Market note · 15 September 2026
A small uptick as coverage keeps climbing
The Agentic Economy Price Index closed the 15 September observation at 100.34, up from 100.324 on 14 September (about +0.016% day-over-day; the public card rounds to +0.02%). Over 30 days the headline is still up +0.20%. Like-for-like coverage rose again — 7,359 pairs, from 7,348 the day before. Pulse released 2026-09-15T06:41:41Z (release_id 19, aepi-ledger-v1).

Keep the scale honest: this is a market whose headline barely moves. Most listings never reprice on a given day, which is why small chained moves and the occasional large published reprice are the useful read.
Agents and MCPs, not one blend
| Scope | Level | Pairs | 30d |
|---|---|---|---|
| All | 100.34 | 7,359 | +0.20% |
| Agents | 100.537 | 2,014 | +0.10% |
| MCPs | 100.442 | 3,981 | +0.23% |
| Infrastructure | 99.627 | 1,214 | +0.22% |
| APIs | 102.12 | 222 | +2.12% |
| Platforms | 98.916 | 925 | −0.19% |
| Frameworks | 100.695 | 67 | 0.00% |
| Skills & plugins | 98.376 | 31 | +2.71% |
APIs remain the strongest 30-day riser in this release set; platforms are still soft. Skills & plugins move hard on a thin cohort (31 pairs) — low confidence by design.
What published
Only published genuine repricings for the day (held / niche-not-indexed / below-movers-bar moves omitted):
- blitzreels Agency (team_sme): $99 → $199/mo (+101.0%)
- blitzreels Starter (individual): $25 → $39/mo (+56.0%)
One provider drove both published movers — a sharp Agency double and a Starter lift. Net still only a fractional headline step: coverage and quiet chain maths matter more than any single card.
