Senators Amy Klobuchar and Chuck Grassley reintroduced the American Innovation and Choice Online Act on June 10, reviving a bipartisan effort that died four years ago. The legislation targets the largest online platforms, aiming to curb self‑preferencing that gives dominant firms an edge. Apple, Amazon, Google and Meta have previously lobbied heavily against similar proposals, and could set a precedent for future regulation.

Supporters argue self‑preferencing harms competitors and skews markets, while critics claim it would force Apple to loosen controls that protect privacy and security on iOS. The bill could reshape the App Store, limiting Apple’s ability to promote its own services. Industry groups disclosed that the tech giants collectively spent $100 million on lobbying to block earlier versions, raising concerns among developers about app visibility.

Earlier drafts cleared the Senate Judiciary Committee but never reached a floor vote, despite bipartisan backing. The resurgence reflects growing congressional appetite to rein in platform power after Europe’s Digital Markets Act forced Apple to alter its European App Store rules. Whether the revived bill will advance remains uncertain, but its return signals renewed pressure on big tech’s ecosystem dominance.
