Four distinct approaches to monetizing AI-mediated commerce have emerged. Each reflects a fundamentally different bet on where value accrues in the new shopping layer.
User searches with intent → Google shows “Direct Offers” from paying merchants → Merchant pays for visibility at the purchase moment. Revenue = Intent × Ad Spend. Familiar model extended from search ads → shopping ads → agent ads. 8.5B daily searches, $175B ad revenue. Open standard (UCP) = more reach.
2. Transaction Fees — OpenAI
User purchases via ChatGPT → Stripe processes payment → OpenAI takes a small percentage as platform fee. Revenue = Volume × Fee %. Path to AI profitability: every purchase funds compute. 810M daily active users, 400M weekly users, Stripe as trusted rails.
3. Infrastructure Tax — Shopify/Stripe
Every AI transaction flows through their infrastructure → Shopify hosts merchants, Stripe processes payments → Collect toll. Revenue = GMV × Infrastructure %. Protocol agnostic. Win regardless of UCP vs ACP. $235B Shopify GMV, $1T+ Stripe volume.
4. Walled Garden — Amazon
Block AI crawlers → Force shoppers to stay on Amazon → Capture full journey value: ads + fulfillment + Prime fees. Revenue = Everything (if you stay). Bet against open ecosystem: protect $56B ad business. 40% market share, 47+ bots blocked.
Google extends its ad model. OpenAI builds commerce infrastructure. Shopify/Stripe win either way. Amazon bets the fortress holds.
