WSJ: Amazon blocks Muse shopping while Walmart and Shopify partner with Meta
Meta's Muse shopping agent is now a visible threat to Amazon's nearly $70 billion advertising business, according to the Wall Street Journal. Amazon has blocked Muse from purchasing on its platform, citing security, while Walmart and Shopify have taken the opposite route and partnered with Meta for agent-driven shopping. The split matters for anyone running a selling agent: channels that welcome agents will capture agent orders first, while blockers must build their own agent play.
