GPU Compute Tightness Index

The GPU Compute Tightness Index fell to 43.8/100 as of June 29, 2026, entering Loose territory after a monthly drop of 13.7 points, indicating abundant idle AI infrastructure and supply exceeding near-term demand. Per-GPU readings show H100 at 37, B200 at 47, and H200 at 57, with spot discounts of 55%, 47%, and 31% below on-demand pricing.

The Compute Tightness Index sank to 43.8/100 as of 2026-06-29 , pushing the blended gauge into Loose territory after a -13.7 pts monthly drop that pulled it under the prior 44–64 range. Per-GPU readings of 37 for H100, 47 for B200, and 57 for H200 correspond to spot discounts of 55% , 47% , and 31% below on-demand, signaling abundant idle AI infrastructure and supply that currently exceeds near-term training and inference demand. It is the input-side companion to the Token Demand Index /token-demand the output — tokens consumed . ← looser · 45 balanced · 60 tight · tighter → As of 2026-06-29 the blended index sits at 43.8 Loose and has been loosening over the past 30 days -13.7 pts . Listing-weighted across H100, H200 and B200 by on-demand market depth. | GPU | On-demand $/hr | Spot $/hr | Spot discount | Listings | CTI | 30d | |---|---|---|---|---|---|---| B200 | $6.42 | $3.43 | 47% | 46 | 46.6 | ▼ -5.9 | H200 | $4.13 | $2.84 | 31% | 69 | 56.9 | ▼ -20.9 | H100 | $3.62 | $1.64 | 55% | 145 | 36.8 | ▼ -13.5 | MI355Xthin · excl. from blend | $8.60 | $0.00 | 100% | 2 | — | Spot discount = how far below on-demand the spot rate trades. A shrinking discount rising CTI means spare capacity is drying up; a widening discount falling CTI means idle GPUs are being dumped on spot. MI355X is tracked for coverage but excluded from the blended index — its listing count is too thin to weight reliably. For each GPU on each day: CTI = 100 × 0.8 · spot avg/on demand avg + 0.2 · unavailable/ unavailable + on demand listings . The scarcity term is the share of listed capacity that has gone dark clamped to 1 . The blended index is the listing-weighted mean across B200, H200 and H100 weighted by on-demand listing count, a proxy for market depth . Inputs are the daily GetDeploying aggregate of public GPU rental listings — on-demand, reserved and spot averages plus availability — one snapshot per day. Reading it: <45 loose · 45–60 balanced · 60–80 tight · 80 acute scarcity. The spot-premium term dominates day to day; the availability term only bites when providers actually go dark, so it spikes the index during genuine capacity crunches.
