The Digital Markets Act (DMA), a historic European regulation aimed at ensuring greater competition on digital markets, comes fully into force. Apple, Alphabet, Meta, Amazon, Microsoft and ByteDance must comply with all the obligations established by the DMA.

The six companies were designated by the European Commission in September last year as gatekeepers. Gatekeepers, who have so far started testing measures to comply with European legislation, will have to demonstrate that they are actually compliant by describing the measures taken in compliance reports.
