Open Markets Institute Europe

Open Markets Institute Europe is a Brussels-based competition-policy advocacy organisation, operating as the European branch of the Open Markets Institute (founded in Washington DC in 2017). It focuses on monopoly enforcement, platform regulation and digital-market competition, conducting research and convening civil-society coalitions to press European institutions for stronger antitrust action. Open Markets Institute Europe does not represent corporate clients; it operates on a non-profit model funded by foundations and philanthropic grants. Its policy positions consistently favour aggressive enforcement of the Digital Markets Act and structural remedies over behavioural conditions in competition cases.

In May 2026 Open Markets Institute Europe led a Coalition of more than 30 civil-society organisations in writing to Commission President Ursula von der Leyen, expressing grave concern at the prolonged delay to the European Commission's DMA fine against Google for search self-preferencing. The fine had originally been scheduled for March 2026; the hold-up was attributed by the Coalition letter to von der Leyen's personal intervention, shifting political accountability from the DG Competition case team to her office . The campaign placed the delay alongside CAIDA's serial deferrals as evidence of political paralysis in EU tech enforcement at a moment when trade pressure from Washington was intensifying.
