DC-GPU Spot Index
TKX-SPI tracks settled per-card spot prices. It stays empty until real settled deals exist on the platform — a listing price is not a trade.
Why is this empty? An index of settled prices needs settled trades. TKX publishes a model's SPI only once at least 3 verified deals exist for it, with methodology version and constituents open for third-party recomputation — the same discipline as TTPI. Until then this reads Collecting, not an estimate.
Rental benchmark (measured)
Live rental rates per GPU-hour, measured on public marketplaces. This is a rental price, not a hardware purchase price — the two are different markets and are never mixed.
Payback calculator
Enter a card price you were quoted; TKX computes payback against the measured rental rate. Your input stays in your browser.
Settlement calculator
The brokerage fee is paid by the buyer; the listed price is what the seller receives. TKX does not deduct it from the goods payment — it is invoiced after settlement.
