Digital Markets Act
An EU regulation targeting large platform 'gatekeepers' with rules on fair competition, data portability, and advertising transparency.
What Digital Markets Act means
The Digital Markets Act (DMA) is an EU regulation that imposes specific obligations on large platforms designated as 'gatekeepers' (including Google, Meta, Apple, Amazon, and others). For advertising, key DMA requirements include: prohibiting gatekeepers from combining personal data across services without consent, requiring interoperability with third-party services, mandating advertiser access to performance data, ensuring ad transparency and measurement verification, and restricting self-preferencing in ad auctions. The DMA complements the DSA and GDPR, creating a comprehensive regulatory framework for digital platforms. Non-compliance can result in fines up to 10% of global annual turnover. The DMA directly impacts how major ad platforms operate in the EU and influences global platform practices.
