Why does Ireland receive 60%+ of DSA Article 26 enforcement cases?

The Ireland concentration in DSA Article 26 enforcement is a structural feature of the EU regulatory framework rather than an accident of implementation. The Irish Data Protection Commission (DPC) serves as the lead supervisory authority for most Very Large Online Platforms because Meta, Google, TikTok, X, LinkedIn, and several other VLOPs maintain their EU headquarters in Ireland for corporate-tax purposes. The 'one-stop-shop' mechanism in EU regulation — established under GDPR and extended to DSA enforcement — channels cross-border cases to the supervisory authority of the country where the platform has its main EU establishment. The mechanism means that any DSA Article 26 violation by Meta, Google, TikTok, or similar Ireland-headquartered VLOPs is handled by the Irish DPC regardless of which EU member state the affected users reside in. A German user filing a complaint about a Meta political ad targeting Germany has the complaint routed through the German national regulator initially, but the substantive enforcement decision is made by the Irish DPC in Dublin. The result is that approximately 60% of cross-border DSA cases in 2025-2026 have landed on the Irish DPC's desk. The concentration produces several operational consequences worth understanding. First, the Irish DPC has had documented capacity constraints — the office's headcount and budget have lagged the volume of cases routed to it, producing case backlogs of 12-18 months for complex cross-border matters. The backlog has been the subject of public criticism from civil society organisations (Access Now, EDRi, Irish Council for Civil Liberties) and from other member states' regulators who experience delays when their cases route through Dublin. Second, the Irish DPC's enforcement philosophy has historically been more cautious than several continental European regulators, producing lower per-case penalty amounts even when the substantive violation is established. Critics characterise the pattern as regulatory accommodation of Ireland's economic interest in retaining Big Tech corporate headquarters; defenders characterise it as principled adherence to procedural fairness. Third, reform proposals are pending. The European Commission's mid-2025 DSA implementation review identified the Ireland concentration as a structural issue and signalled possible structural reforms including a dedicated EU-level DSA enforcement body that would sit alongside or above the national supervisory authority framework. The reforms are unlikely to take effect before late 2027 even if approved. For advertisers, the practical implication is that DSA Article 26 enforcement timing is dominated by Irish DPC processing capacity, and case-resolution timelines should be planned accordingly. The defensive posture is to avoid generating cases in the first place. Article 26 violations are typically procedural rather than substantive, which means they can be prevented through standard compliance discipline rather than requiring strategic judgement calls. Advertisers who treat Article 26 as a tactical compliance area rather than a strategic one absorb the framework with significantly less risk and overhead. The structural advantage of preventive compliance is amplified by the Ireland-routing pattern because once a case enters the backlog the resolution timeline is largely outside the advertiser's control, and the lost-time cost of unresolved compliance exposure compounds. See the EU DSA Compliance Guide for the broader EU regulatory landscape.

How does Article 26 interact with the EU's Political Advertising Regulation (Regulation 2024/900)?

EU Regulation 2024/900 — formally the Political Advertising Regulation (PAR) — is the EU's dedicated political advertising framework adopted in early 2024 with a phased application schedule beginning October 2025. The PAR overlaps with DSA Article 26 but operates as a separate regulatory layer with distinct requirements, distinct supervisory mechanisms, and distinct penalties. Understanding the interaction is critical for compliance posture. The DSA Article 26 framework applies to VLOPs and imposes platform-side obligations around the political ad library, retention, advertiser identification, and targeting disclosure. The framework was operational from August 2023 for designated VLOPs and is fully in force across all 27 member states. The Political Advertising Regulation applies more broadly to political advertising regardless of distribution platform — it covers political ads on VLOPs, on smaller platforms, on traditional media (TV, radio, print), and through other distribution channels. The PAR also imposes more specific substantive requirements: advertiser-side transparency labels on the ad creative itself, restrictions on profiling for political ad targeting that go beyond DSA's broader disclosure framework, sponsor-identification requirements that extend to influencers and other intermediaries, and country-of-origin disclosure for cross-border political ads. The interaction between the two frameworks is overlapping rather than substitutive. A political ad served on Meta in Germany faces both DSA Article 26 obligations (Meta-side library entry, retention, targeting disclosure) and PAR obligations (creative-level transparency label, profiling restrictions, sponsor identification down to ultimate funder). Compliance with one does not satisfy the other. The supervisory mechanisms also differ: DSA Article 26 enforcement runs through the Ireland-concentrated VLOP supervisory authority framework described above; PAR enforcement runs through national-level supervisory authorities in each member state with EU coordination through the European Cooperation Network on Elections. The penalty layers are independent and can stack — a single political ad violation can trigger DSA Article 26 enforcement (via Irish DPC) and PAR enforcement (via German Bundesnetzagentur, for example) concurrently. The PAR penalties reach up to 6% of annual worldwide turnover for repeated serious infringements, comparable to DSA's penalty ceiling. The Q4 2025 first-application window of the PAR coincided with the German federal election campaign and produced the first published enforcement actions under the new framework, with the case load expected to expand through 2026. The dual-framework operational discipline that advertisers must develop is to treat both frameworks as concurrent compliance requirements rather than alternatives, and to invest in compliance infrastructure that addresses both in a single workflow rather than two parallel ones. The natural temptation is to focus on the framework that produced the immediate trigger for compliance work (typically DSA Article 26 because of its earlier effective date), but the PAR layer carries equal substantive weight and the supervisory mechanisms are independent. Compliance documentation should explicitly cover both frameworks per campaign with separate sign-off, and audit trails should be structured to support inquiry under either framework. The dual coverage adds operational overhead but eliminates the risk of discovering PAR exposure during a DSA Article 26 enforcement action — a scenario that has occurred in 2025-2026 enforcement records. For coordinated cross-framework compliance see the Legal Compliance Scan and for the deeper EU regulatory framework see EU DSA Compliance Guide .

What are the penalty amounts and case patterns under Article 26 through 2026?

DSA Article 26 enforcement through May 2026 has produced a tiered penalty pattern with several published cases establishing the operational range. The structural penalty framework under Article 74 of the DSA caps fines at 6% of the platform's annual worldwide turnover for serious or repeated infringements. For the largest VLOPs, the cap translates to multi-billion euro maximum exposure per consolidated enforcement action. The Q4 2025 case load included the first major published DSA Article 26 enforcement decision against a designated VLOP for incomplete ad library disclosure — the case settled with a penalty in the low nine figures (€100-200M range) and a corrective order requiring schema-compliant disclosure within 90 days. The settlement amount sits well below the theoretical cap because the case was treated as a first-instance procedural violation rather than a substantive transparency failure. The Q1 2026 case load expanded with three additional published decisions: two against mid-tier VLOPs for retention period non-compliance (records expiring before the required one-year window) and one against a major VLOP for targeting parameter disclosure gaps. Aggregate Q1 2026 penalty totals reached approximately €350M across the three published decisions and additional smaller settlements. The case patterns identify several persistent compliance gaps that advertisers should understand. First, retention compliance is the most frequent violation category — ad records being purged or becoming inaccessible before the one-year minimum window. Second, advertiser identification gaps are common, particularly where pass-through entities (agencies, PACs) are listed as advertiser of record without ultimate-funder disclosure. Third, targeting parameter disclosure has been incomplete on most platforms — the structured format requirements are interpreted differently by different platforms and the resulting library entries vary in completeness. Fourth, cross-border ads (running in multiple EU countries simultaneously) have shown the highest compliance gap rate, with the additional jurisdictional complexity contributing to errors. The penalty trajectory through the remainder of 2026 is expected to escalate as the Q3-Q4 enforcement-priority window approaches. The Irish DPC's published 2026 enforcement priorities placed DSA Article 26 in the top tier, signalling sustained case-flow through year-end. For ongoing enforcement tracking see /enforcement and for cross-jurisdiction penalty analysis see the Legal Compliance Scan . The penalty trajectory has also produced a secondary effect worth noting: platforms have responded to early enforcement actions by tightening their own ad-product compliance review for political ads, which means advertisers experience longer review queues and stricter rejection thresholds during peak political ad windows than they did prior to active Article 26 enforcement. The platform-side tightening is itself a compliance cost for advertisers — production timelines must extend to absorb the additional review latency. The combined effect of direct penalty exposure plus indirect operational cost makes Article 26 a meaningful budget line item for advertisers running EU political campaigns at scale, with mid-sized programs reporting compliance overhead of 8-15% of total campaign budget through 2025-2026. The overhead is expected to stabilise as platforms refine their review infrastructure but is unlikely to drop below high single digits for the foreseeable future. Advertisers should plan compliance overhead and contingency budgets accordingly, particularly for cross-border EU political campaigns running during election windows.

How should non-EU advertisers handle Article 26 obligations for EU-targeted political ads?

Article 26 obligations attach to political ads served to EU users regardless of where the advertiser is based — a US-based campaign committee running ads targeting EU users via Meta, Google, or TikTok faces the same Article 26 obligations as an EU-based advertiser. The framework treats the user's location at the time of ad delivery as the jurisdictional anchor, not the advertiser's headquarters location. The practical compliance posture for non-EU advertisers requires several adjustments to the standard ad operations workflow. First, the political ad classification must be applied at the campaign setup stage on each platform. Meta's political ad registration, Google's election advertiser verification, and TikTok's political ad pre-approval each require explicit declaration that the campaign is political in nature and is targeting EU users. The declaration triggers the platform-side compliance flow that enables Article 26-compliant disclosure. Failure to declare results in either ad rejection or — more dangerously — ads running outside the political ad system and creating both Article 26 violation exposure and platform-policy violation exposure. Second, advertiser identification must extend to the ultimate funder, not just the payment-method holder. Non-EU advertisers using pass-through entities (US PACs, party committees, advocacy organisations) for EU-targeted political ads must document and disclose the ultimate funder chain. The disclosure obligation is on the advertiser, and the platform's library will display the disclosed identification. Inadequate disclosure produces Article 26 violations that propagate to the advertiser. Third, targeting parameter discipline must conform to PAR restrictions in addition to Article 26 disclosure. The PAR places substantive limits on profiling-based political ad targeting in the EU that go beyond US-standard targeting practices. Non-EU advertisers accustomed to behavioural targeting on US platforms face restrictions on the same targeting parameters when the ads are EU-targeted. Fourth, cross-border ad management requires per-country compliance review. A campaign running in Germany, France, and Italy simultaneously faces three sets of national supervisory authority oversight in addition to the Irish DPC routing for VLOP-level violations. The complexity is the largest single source of compliance error for non-EU advertisers entering EU political ad markets. The recommended preparation is a 60-90 day pre-campaign compliance setup involving platform political ad registration, advertiser identification documentation, targeting parameter conformity review, and per-country compliance counsel engagement. The setup is operationally significant and should not be compressed into a last-minute campaign launch. Non-EU advertisers entering EU political ad markets for the first time should plan for the 60-90 day setup window as part of the campaign timeline rather than as a parallel administrative task — the dependencies between platform registration, advertiser identification documentation, and creative-level disclosure preparation make sequential execution the most reliable path. Second-time entrants benefit from prior setup work and can typically compress the window to 30-45 days, but the documentation and counsel-engagement components still require their own lead times. The compression advantage is the primary return on the initial setup investment and justifies the higher first-year overhead. Compressing the setup typically produces either ad rejection at launch or library-record gaps that surface as Article 26 violations within the first 72 hours. The reputational cost of either failure mode tends to exceed the cost of the upfront setup investment. For coordinated cross-jurisdiction review see the Legal Compliance Scan .

What's the practical advertiser checklist for Article 26 compliance before EU campaign launch?

The practical advertiser checklist for Article 26 compliance falls into five work areas with concrete deliverables and timelines. The five areas should be completed in the documented sequence, with each area depending on the prior one's completion. Sequence skipping is the most common avoidable compliance error pattern observed in 2025-2026 campaign post-mortems. Area one — platform registration and verification. The advertiser must complete each target platform's political ad registration and verification flow before any campaign creative is uploaded. Meta's political ad registration takes 5-10 business days; Google's election advertiser verification similar; TikTok's political ad pre-approval queue extends to 7 days during peak. The registration should be initiated 14-21 days before intended campaign launch to provide buffer for re-submission if initial verification fails. The verification step requires documentation of advertiser legal identity, ultimate funder identification, and (for non-EU advertisers) EU representative designation. Area two — advertiser identification documentation. The advertiser must prepare and submit complete advertiser identification information including legal name, registered address, ultimate funder chain (for pass-through entities), and contact details. The information will populate the platform's political ad library and must be accurate at the time of campaign launch. Identification errors discovered after campaign launch trigger library-record correction obligations and may produce inquiry from the Irish DPC or other supervisory authorities. Area three — targeting parameter conformity review. The advertiser's planned targeting parameters must be reviewed against both Article 26 disclosure requirements and Political Advertising Regulation profiling restrictions. The review identifies any targeting parameters that violate the PAR profiling restrictions and produces a targeting plan compliant with both frameworks. The review should be documented for audit purposes and signed off by EU compliance counsel. Area four — creative-level disclosure preparation. Each ad creative must include the appropriate disclosure label (paid for by, political ad designation, country of origin for cross-border ads). The disclosure label must conform to platform-specific formatting requirements while satisfying the PAR's creative-level transparency obligations. Disclosure preparation typically requires creative production rework if the original creative was designed without disclosure overlay space. Area five — post-launch monitoring and library verification. Within 24 hours of campaign launch, the advertiser should verify that the political ad library records have populated correctly with all required fields. Library records with missing or incorrect data should trigger immediate platform support escalation. The 24-hour window is critical because Article 26's near-real-time obligation makes delayed correction a substantive violation rather than a procedural delay. The five-area checklist is structured as a sequence rather than a parallel list because each area depends on the prior one's completion — area three (targeting parameter review) requires the registration of area one to be complete, and area five (post-launch monitoring) is meaningless without the foundation laid in areas one through four. Compliance teams that execute the checklist as parallel work streams report higher error rates than teams that execute sequentially. The structural discipline is therefore as important as the substantive content of the checklist.

EU DSA Article 26 2026: Political Ad Transparency Data

Quick Answer

EU DSA Article 26 mandates political advertising transparency across all 27 EU member states — public Ad Library entries with retention periods of at least one year, advertiser identification, targeting parameter disclosure, and audience reach data. First-year implementation through May 2026 shows uneven member-state enforcement activity, with Ireland receiving over 60% of cross-border cases as lead supervisory authority for most VLOPs. Penalty cases through Q1 2026 reached aggregate figures in the low hundreds of millions of euros, with the structural enforcement bottleneck concentrated in Dublin.

EU DSA Article 26 — Political Advertising Transparency: First-Year Implementation Data Across 27 Member States

Why Article 26 Is the 2026 Compliance Anchor

EU DSA Article 26 is the structural anchor for political advertising compliance across the European Union in 2026. The provision — part of Regulation (EU) 2022/2065 (the Digital Services Act) — imposes mandatory transparency obligations on Very Large Online Platforms (VLOPs) hosting political advertisements: a public political ad library, retention periods of at least one year, advertiser identification including ultimate funder, and targeting parameter disclosure in machine-readable format.

The framework has been operational since August 2023 for designated VLOPs and reached full first-year implementation across 27 EU and 3 EEA member states by mid-2025. The first 18 months of enforcement data, now available through Q1 2026, surface several structural patterns that advertisers planning EU-targeted political campaigns must understand. Implementation is uneven across member states. Ireland is the gravitational center of enforcement because most VLOPs maintain EU headquarters in Dublin and the Irish DPC serves as lead supervisory authority. Penalty cases are scaling, with aggregate Q1 2026 totals reaching approximately €350M across published decisions.

This guide walks the provision itself, the cross-member-state implementation variation, per-platform compliance rates, the structural Ireland enforcement bottleneck, the 2025-2026 penalty case pattern, and the practical compliance checklist for non-EU advertisers entering the framework.

"Providers of very large online platforms that present advertisements on their online interfaces shall compile and make publicly available in a specific section of their online interface a repository containing the information referred to in this Article."
— Regulation (EU) 2022/2065 (Digital Services Act), Article 39 (as referenced through Article 26)

Article 26 — The Provision Itself

Article 26 of the DSA imposes four core obligations on VLOPs hosting political advertisements. The obligations operate at the platform layer with downstream advertiser cooperation requirements, and apply uniformly across all 27 EU and 3 EEA member states.

Public political ad library

VLOPs must maintain a publicly accessible repository of all political advertisements served on the platform. The library must be searchable, machine-readable through API access, and free to access without authentication. Meta's Ad Library, Google's Political Advertising Transparency Center, and TikTok's Commercial Content Library are the platform implementations.

Retention periods

Each political ad record must be retained for at least one year from the date the ad last ran. The retention applies to the full record — actual creative, targeting parameters, reach figures, and advertiser identification all remain accessible for the full window. Records purged before the one-year minimum trigger Article 26 violation.

Advertiser identification

The natural or legal person who paid for the political advertisement must be identified in the public record. The obligation extends to identifying the actual funding source when the advertiser of record is a pass-through entity (agency, PAC, campaign committee). The transparency runs to the ultimate funder, not just the payment-method holder.

Targeting parameter disclosure

The audience targeting parameters used to deliver the political ad must be disclosed in the public record. This includes demographic targeting, interest-based targeting, behavioural targeting categories, and audience-list-based targeting if a custom audience was used. The disclosure is structured rather than narrative — machine-readable format is mandatory.

Article 26 also imposes timing requirements: records must appear in the library within 24 hours of the ad first running; updates to ad metadata must propagate within an additional 24-hour window. The result is a near-real-time transparency framework rather than periodic disclosure.

27 Member States — Implementation Variation

Article 26 imposes uniform obligations across the EU but member state implementation has varied significantly. The variation reflects different national regulator capacities, different national enforcement priorities, and the cross-border supervisory framework that channels VLOP-level cases through specific national authorities.

Member State	National Regulator	2025-2026 Enforcement Posture
Ireland	Data Protection Commission (DPC)	Lead supervisory for most VLOPs; concentrated case load
Germany	Bundesnetzagentur (BNetzA)	Active national-level enforcement; PAR coordination
France	ARCOM	Aggressive substantive enforcement; specialised audiovisual focus
Italy	AGCom	Active enforcement; cross-border coordination
Spain	CNMC	Active enforcement; democratic-process focus
Netherlands	Autoriteit Consument & Markt	Active enforcement; algorithmic transparency focus
Belgium	BIPT	Active enforcement; EU institutional adjacency
Austria	RTR	Active enforcement; broad inclusion in territorial scope
Poland	UKE	Implementation focus; capacity-building phase
Sweden	PTS	Coordinated enforcement; Nordic council collaboration

The variation matters for advertisers because cross-border campaigns face oversight from multiple national authorities in addition to the Irish DPC routing for VLOP-level violations. A campaign running in Germany, France, and Italy simultaneously faces three sets of national-level oversight plus Irish DPC coordination — four supervisory authorities for a single campaign. The complexity is the largest single source of compliance error for non-EU advertisers entering EU political ad markets.

Beyond the formal supervisory structure, member states have varied in their public guidance and outreach to advertisers. Germany's BNetzA has published detailed operational guidance with worked examples for political ad classification edge cases. France's ARCOM has run advertiser training sessions in coordination with industry associations. Italy's AGCom has issued sector-specific guidance for political advertising during election windows. The Northern European cohort (Sweden, Denmark, Finland, Netherlands) has produced coordinated guidance through Nordic Council channels. The Eastern European member states have been comparatively quieter on public guidance, focusing capacity on internal implementation rather than external advertiser outreach. The guidance variation produces an information asymmetry that experienced EU political advertisers can exploit and that newer entrants must invest to overcome through engagement with national-level industry associations and EU-level legal counsel.

Per-Platform Compliance Rate

VLOP compliance with Article 26's specific requirements has varied across the cohort. Audit-rate disclosure, ad library completeness, retention period compliance, and targeting parameter machine-readability have all been areas of platform-specific gap.

Platform	Library Coverage	Retention Compliance	Targeting Disclosure
Meta (Facebook + Instagram)	High — Ad Library mature	High — explicit one-year retention	Medium — structured but incomplete
Google (Search + YouTube)	High — Political Transparency Center	High	High — well-structured disclosure
TikTok	Medium — Commercial Content Library launched late 2024	Medium — early retention gaps remediated	Low — disclosure structure inconsistent
YouTube (via Google framework)	High — inherits Google framework	High	High
X (formerly Twitter)	Low — repeated coverage gaps in 2025	Low — multiple retention violations	Low — minimal targeting disclosure

The platform-level variation produces uneven advertiser experience. Campaigns running on Meta and Google enter mature, well-structured library systems with clear disclosure flows. Campaigns running on TikTok face evolving library infrastructure with frequent platform-side updates that require advertiser-side adjustment. Campaigns running on X face the highest compliance risk because the platform's library coverage gaps create both platform-level enforcement exposure and downstream advertiser exposure.

The Q1 2026 published enforcement cases concentrate on X (two cases for retention period non-compliance), TikTok (one case for targeting disclosure gaps), and Meta (one case for ultimate-funder disclosure gaps). The cases collectively account for the ~€350M aggregate Q1 2026 penalty figure cited earlier.

The asymmetry of platform compliance maturity has downstream consequences for advertisers planning multi-platform EU political campaigns. The natural temptation is to run the same campaign across all major platforms with a single creative and disclosure package; the reality is that each platform's library structure imposes specific formatting constraints that produce per-platform variation in the disclosure submission. The operational discipline that disciplined campaign teams adopt is to maintain platform-specific compliance templates and to verify library record completeness within 24 hours of each platform launch — a workflow that adds modest overhead but eliminates the most common Q1 2026 violation patterns. Campaigns that run with a unified single-template approach face elevated risk of platform-specific gaps surfacing as Article 26 violations.

Hidden Gem — The Ireland Effect

The Ireland concentration in DSA Article 26 enforcement is a structural feature of the EU regulatory framework that advertisers and analysts often miss. The Irish Data Protection Commission (DPC) serves as the lead supervisory authority for most VLOPs because Meta, Google, TikTok, X, LinkedIn, and other major platforms maintain EU headquarters in Ireland for corporate-tax purposes. The 'one-stop-shop' mechanism in EU regulation channels cross-border cases to the supervisory authority of the country where the platform has its main EU establishment.

The mechanism means that any DSA Article 26 violation by Ireland-headquartered VLOPs is handled by the Irish DPC regardless of which EU member state the affected users reside in. A German user filing a complaint about a Meta political ad targeting Germany has the complaint routed through the German national regulator initially, but the substantive enforcement decision is made by the Irish DPC in Dublin.

Approximately 60% of cross-border DSA cases in 2025-2026 have landed on the Irish DPC's desk. The concentration produces three operational consequences. First, capacity constraints — the Irish DPC's headcount has lagged the case volume, producing case backlogs of 12-18 months for complex cross-border matters. Second, enforcement philosophy — the Irish DPC has historically been more procedurally cautious than several continental regulators, producing lower per-case penalty amounts even on established violations. Third, reform pressure — the European Commission's mid-2025 DSA implementation review identified the Ireland concentration as a structural issue and signalled possible reforms including a dedicated EU-level DSA enforcement body. Reforms are unlikely to take effect before late 2027 even if approved.

For advertisers, the practical implication is that DSA Article 26 enforcement timing is dominated by Irish DPC processing capacity. Case-resolution timelines for substantive Article 26 violations should be planned with 12-18 month windows in mind, and compliance posture should be calibrated to prevent violations rather than rely on appeal of adverse decisions through a backlogged system. For coordinated EU compliance review see the EU DSA Compliance Guide.

Penalty Cases 2025-2026

DSA Article 26 enforcement through May 2026 has produced a tiered penalty pattern with several published cases establishing the operational range. The structural penalty framework under Article 74 of the DSA caps fines at 6% of the platform's annual worldwide turnover for serious or repeated infringements — multi-billion euro maximum exposure per consolidated enforcement action for the largest VLOPs.

Q4 2025 — first major published Article 26 decision: Settled at €100-200M against a designated VLOP for incomplete ad library disclosure. Corrective order required schema-compliant disclosure within 90 days.
Q1 2026 — three additional decisions: Two against mid-tier VLOPs for retention period non-compliance (records expiring before one-year minimum); one against a major VLOP for targeting parameter disclosure gaps. Aggregate ~€350M across the quarter.
Pending Q2 2026: Multiple investigations active with decisions expected by July; case load weighted toward retention compliance violations and ultimate-funder disclosure gaps.

Four persistent compliance gap categories explain most published cases. First, retention compliance — ad records being purged or becoming inaccessible before the one-year minimum. Second, advertiser identification gaps where pass-through entities (agencies, PACs) are listed without ultimate-funder disclosure. Third, targeting parameter disclosure that does not conform to the structured machine-readable format. Fourth, cross-border ads showing the highest compliance gap rate because of jurisdictional complexity.

The penalty trajectory through the remainder of 2026 is expected to escalate as Q3-Q4 enforcement priorities approach. The Irish DPC's published 2026 enforcement priorities placed DSA Article 26 in the top tier. For ongoing tracking see /enforcement.
