The US Senate Judiciary Committee approves the Open App Markets Act, which would allow app sideloading and let developers use their own in-app payment systems
The U.S. Senate Judiciary Committee today approved the bipartisan Open Markets Act, an antitrust bill that would allow for sideloading and alternate app stores on the iPhone.
Context & Ripple Effects
The bill's road to today started with an April 2021 [[a:965543|subcommittee hearing where Apple, Google, Spotify, and Tile testified on app store competition]], followed by the bipartisan unveiling by three senators that August and a House companion bill. Committee approval now moves it past the drafting stage, and it lands alongside a second antitrust push from the same panel: last month the committee voted 16-6 to advance the American Innovation and Choice Online Act targeting self-preferencing platforms.
What makes this approval notable is that it is procedural momentum, not law — as later coverage shows, this version never reached a floor vote and was reintroduced in 2025. The committee stage is where the sideloading and in-app-payment mandates gained their first formal traction.
First-order effects
- Apple and Google would be legally required to permit sideloading and alternate app stores on iOS and Android respectively, ending their exclusive control over app distribution on their own devices.
- Developers would gain the right to route payments through their own systems instead of being locked into each store's in-app purchase rails and commission structure.
Second-order effects
- Alternate app store operators and payment providers get an addressable market on iOS for the first time, shifting pricing pressure onto Apple's and Google's commission rates rather than just their policies.
- Google faces the same mandate despite Android's existing openness, because its leverage runs through Play Store rules rather than OS lockout — so compliance costs hit both gatekeepers, not just the more closed one.
Third-order effects
- If the pattern holds across reintroductions, app store gatekeeping becomes a recurring legislative target regardless of any single bill's fate, forcing Apple and Google to defend distribution economics in Congress indefinitely.
- The endgame is contestable gatekeeping: platform control over access layers persisting in form while developers hold statutory leverage over terms — a structure regulators elsewhere are watching.
The trend: US lawmakers are converting app store competition from hearing-stage scrutiny into binding legislation, with committee advances outpacing the Senate floor where these bills stall.
