Independent. Transparent.
Built for the compute
market.
TCI publishes reproducible reference prices for AI and HPC compute — methodology-driven, vendor-neutral, and rebuildable from public sources by anyone.
Headline series — today
One row per class the index prices, for the 7 Sep 2026 session. A class below the provider gate keeps its row and states the gate it missed; the last good value is never promoted into today's slot.

|---|---|---|---|
| TCI‑CRI‑H100 | EU/EEA | $3.25 | ±0.00% |
| TCI‑CRI‑H200 | EU/EEA | — | gap · below the provider gate |

TCI‑CRI‑H100
NVIDIA H100 SXM 80GB, on-demand, EU/EEA regions. Weighted median over offers, per GPU-hour, ex-VAT.
Sub-indices
The segment and variant cuts of the headline. A series below the provider gate keeps its slot and shows a gap with the reason.

TCI‑CRI‑H100
USD per GPU-hour · 30 sessions to 7 Sep 2026 · 16 published, 14 gapped
A gapped session is drawn as a hairline tick on the baseline and the line breaks across it. Nothing is interpolated: the index publishes a gap rather than a value it cannot defend.

Sources
Every collector the index reads. Overlay data (power prices) is published beside the index and never enters the calculation.
How the number is made
Three commitments, each one checkable against the repository rather than taken on trust.
Reproducible
Every parameter is a visible config value, and the five files that can change a print are hash-locked. Every print can be rebuilt from public sources by anyone with the repo.
Vendor-neutral
A weighted median over offers from marketplaces, neoclouds and sovereign operators, gated at 5 providers, with a 25% concentration cap — no single source sets the price.
Open methodology
Design follows the IOSCO Principles for Financial Benchmarks as voluntary best practice — published, versioned, and change-controlled, with the full constituent set behind every print.
A family of indices
One index is published today. The rest are stated as what they are — in development or planned — and carry no numbers until they do.
TCI‑CRI
Compute Reference Index — GPU-hour pricing across 6 hardware classes, published daily with its full constituent set.
TCI‑ERI
Energy Reference Index — the power cost behind the compute cost. Day-ahead power prices are already collected as an overlay; they do not enter any index value.
TCI‑SRI
Storage Reference Index — reference pricing for high-throughput storage. No data is collected for this yet.
