Marketplace Basis
CCIR's headline reference rate is built from posted list-asks: every panel source posts a rate card. Vast.ai posts a different kind of number: a live marketplace ask that reprices continuously. So Vast is kept out of the Tier 3 list-ask panel and tracked here instead, as a basis against that panel. Positive basis means Vast is pricing above the posted panel. Negative means below.
| Chip | List-ask · T3 | Vast | Basis · 7d |
|---|---|---|---|
| B200 | $5.71 2 sources | $6.00 on-demand · posted ask | +5.2% 1d -2.5% |
| H200 | $3.82 3 sources | $4.01 on-demand · posted ask | +5.1% 1d +31.8% |
| H100 | $3.02 9 sources | $1.82 on-demand · posted ask | -39.6% 1d -38.6% |
| A100 80GB | $1.44 6 sources | $0.83 on-demand · posted ask | -42.1% 1d -44.1% |
| A100 40GB | $1.98 5 sources | $0.60 on-demand · posted ask | -69.7% 1d -79.8% |
As of 2026-09-01 · 7-day window · operator-equal medians on both sides, matched tier (Tier 3), guaranteed on-demand terms. The list-ask panel excludes Vast. Where Vast exposes an interruptible reserve bid, the Vast side uses it, flagged on the row. Otherwise it uses the posted on-demand ask. The 1d line repeats the computation on today's prints only. Single-venue signal: Vast is the one live marketplace in the panel.
Implied market utilization — Vast marketplace
The same venue's listings disclose how much of each machine is currently rentable: enough to reconstruct occupancy machine by machine, snapshot by snapshot. Both lines read the same direction: higher means tighter. Capacity (solid): share of listed GPU capacity not currently rentable. Whole nodes (dashed): share of machines without a rentable 8-GPU block. The panel-wide availability view is a separate product (see Availability), and the two are never blended.
Four snapshots daily. A machine with zero rentable chunks may be fully rented or host-paused. The public feed cannot distinguish them, so the utilization read is IMPLIED: share of listed capacity not currently rentable. Denominator is listed capacity only. History begins 2026-05-13. Single-venue market-intelligence signal.
