MWITA-AGC-2026-010 · Evidence C · P1
After excluding identified wash and test activity, Visa and Artemis reported measurable but differently scaled x402 and MPP machine-payment use.
What this does not establish
Mostly machine-to-machine micropayments; counts do not demonstrate consumer-shopping adoption, welfare or autonomous intent.
Counterevidence & uncertainty
Adjusted x402 totals remain materially above the independent study's defensible lower bound and require reconciliation.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform changes and deployed commercial outcomes.
