AGENT WARS: AMAZON VS. MUSE

Summary from the TLDR Fintech newsletter

Simon Taylor argues that Amazon's decision to block Meta's Muse agent is an early battle over who owns the customer, captures commerce fees, and bears liability when AI agents transact on users' behalf. He expects the key infrastructure layer to be “Know Your Agent” standards that authenticate agents, define delegated authority, and allocate liability, with merchants, wallets, card networks, platforms, and infrastructure providers all competing to control that trust layer.
