Apple has been fighting antitrust regulators globally and is about to lose another battle in the US after attempting to charge commissions on third-party payment platforms. In a regulatory filing, Apple admits it may no longer be able to extract such fees.

The EU Commission first forced Apple to allow third-party app stores, challenging its 30% commission on purchases. Similar rulings followed in Japan and Brazil. In the US, courts required Apple to permit alternative payment platforms for in-app purchases, but the company imposed a 27% commission plus 3% processing fees, effectively maintaining its revenue model.

A US judge deemed this a clear abuse of the ruling. Apple argued the court didn't specify acceptable rates but offered reduced commissions: 15% for standard apps, 10% for partner programs and subscription renewals, and 5% for Small Business Program apps.

Despite these concessions, Apple acknowledges it will likely collect nothing from third-party platforms. Services revenue faces a sharp decline over coming quarters — a first for the company — which will likely impact Apple's valuation.
