The Varosity AI GTM Report — Sep 21: Amazon Blocks Meta's Agent, Shopify Hands It Checkout

Agentic commerce split in two over one weekend: Amazon blocked Meta's Muse agent from Amazon.com on Sunday, and on Monday Shopify announced agentic checkout with Shop Pay for that same agent across every store on its platform. Meanwhile Muse hit No. 1 on the US app charts and Meta's market cap jumped past $1.89 trillion, a researcher found a zero-day in Muse's Mac app that leaks the account auth token, SpaceXAI shipped Grok 4.7 at unchanged token pricing but higher token burn, Xiaomi open-sourced Opus-5-class agent performance under an MIT license, and Ireland fined Google €403 million over ad-targeting location data. Jack King on what all of it means for revenue and go-to-market teams.
