Definition
The Digital Markets Act (DMA) is EU legislation that imposes structural behavioral requirements on designated “gatekeepers” — large digital platforms with significant market power. Unlike traditional antitrust law (which reacts to harm after the fact), the DMA proactively prohibits specific behaviors and mandates interoperability, data portability, and open access. Gatekeepers designated include Apple, Meta, Google/Alphabet, Amazon, Microsoft, and ByteDance/TikTok.
Why It Matters
The DMA is the EU’s most ambitious attempt to structurally rebalance power between dominant platforms and the businesses and users who depend on them. It creates enforceable obligations without requiring proof of specific harm — reversing the traditional antitrust burden. The €1M SBLC complaint against Apple shows both the DMA’s ambition (it compelled Apple to allow third-party app stores) and its limits (Apple complied technically while creating new barriers).
Evidence & Examples
- Apple complaint: Article 19 and Society for Civil Rights filed DMA complaint over Apple’s €1M standby letter of credit requirement, which effectively excludes SMEs from iOS distribution Apple Hit with EU Antitrust Complaint Over App Store Policies
- DMA penalties: up to 10% of global annual revenue; repeated violations up to 20%
- Apple’s defense: “The EC is mandating how we run our store and forcing business terms that are confusing for developers and bad for users” — Apple positions DMA compliance as regulatory overreach Apple Hit with EU Antitrust Complaint Over App Store Policies
- DMA alongside AI Act and DSA: the EU’s three-instrument digital regulation package; each targeting different aspects of platform power
- DSA connection: Digital Services Act (companion legislation) mandates data access for researchers studying platform harms Echo Chamber Research Systematic Review
Tensions & Counterarguments
- The DMA’s “gatekeeper” designation requires market power at a scale that small platforms will never trigger — regulatory benefit flows mainly to large incumbents and their competitors, not to genuinely new entrants
- Technical compliance vs. substantive compliance: Apple’s SBLC requirement shows how companies can comply with the letter while violating the spirit
- The DMA is EU-only; US tech companies face no equivalent structural obligations in their home market
- Some argue the DMA’s interoperability requirements will harm security and privacy by forcing open closed ecosystems
- Speed of enforcement vs. speed of tech innovation: DMA investigations take years; tech changes in months
