An AI agent can recommend any retailer, but it can only buy from the ones whose checkout it can actually complete. This study scores the readiness of leading retailers for agent-driven checkout and payment in 2026. We define agent-payable as a site where an AI agent can complete a purchase without a human stepping in to clear a captcha, create an account, or re-enter payment details. Across the top 200 retailers we track, only 23% are fully agent-payable today, though another 38% are one fix away. The leaders are not always the biggest names.
Agent-Payable Readiness Among Top Retailers
We group the top 200 retailers by readiness band. Each band reflects how an agent fares attempting a real purchase.
| Readiness band | Share of top 200 | Agent checkout success | Typical blocker |
|---|---|---|---|
| Fully agent-payable | 23% | 86% | None |
| Near-ready | 38% | 58% | Login wall |
| Partially ready | 24% | 34% | Captcha |
| Not ready | 15% | 12% | Multiple |
Readiness by Retail Segment
Digitally native and marketplace retailers lead, while category specialists and luxury lag on automated checkout.
| Retail segment | Avg readiness score (0-100) | Fully payable share | Has agent payment rail |
|---|---|---|---|
| Marketplaces | 74 | 41% | 52% |
| Digitally native brands | 68 | 36% | 44% |
| Big-box general retail | 57 | 24% | 29% |
| Category specialists | 48 | 16% | 18% |
| Luxury and premium | 39 | 9% | 11% |
Key Findings
- Only 23% are fully agent-payable. Most top retailers can be discovered and recommended by agents but cannot yet be transacted with end to end.
- The login wall is the common near-miss. 38% of retailers are near-ready and blocked mainly by forced account creation, the easiest blocker to remove.
- Marketplaces lead, luxury lags. Marketplaces score 74 on readiness while luxury sits at 39, leaving high-margin agent demand unserved in premium categories.
Methodology
Data is compiled from the Presenc AI monitoring platform plus public sources, with Presenc AI estimates used where authoritative figures are unavailable. Readiness scores are modeled from observed agent sessions, public commerce signals, and vendor-reported benchmarks. Projections use compound growth modeling. Findings are reviewed quarterly.

How Presenc AI Helps
If agents recommend you but cannot check out, you lose the sale to a more payable competitor. Presenc AI scores your store against the agent-payable criteria in this study and shows exactly which blocker is costing you agent revenue. Track which AI agents hit your site and get your agent-payable readiness grade to move up a band before your category does.
