GPU Compute Tightness Index
The Compute Tightness Index dropped to 43.8/100 as of 2026-06-29, entering Loose territory with a -13.7 pt monthly decline. Spot discounts on H100, B200, and H200 reached 55%, 47%, and 31%, signaling abundant idle AI infrastructure and supply exceeding near-term demand.

Compute Tightness Index
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 (the output — tokens consumed).

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.
Methodology
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: 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. Young series (data since 2026-05-07); thresholds will calibrate as history accrues. Full daily history is available as CSV.
