BTC: Perpetual Funding Rate Heatmap (All Assets)
Shown as its 2–31 Oct 2026 sample; the latest readings and full history are included with Plus.
Every coin's perpetual funding rate in each period as an 8-hour rate, one row per coin.
Why use it. Shows at a glance which coins have crowded longs or crowded shorts, and whether crowding is spreading across the market or sits in a few names. How to read it. Coins run down the side, largest open interest at the top, and time runs across; each cell is one coin in one period. Blue cells are positive funding (longs pay), red cells negative (shorts pay), on a two-sided scale. The summary value is the open-interest-weighted rate over every coin.
Calculation. Each cell is the coin's open-interest-weighted perpetual funding rate (its Futures Perpetual Funding Rate chart). Source: our own minute-by-minute collection of public futures data across every coin with perpetual futures that CryptoKeyhole covers, from Binance, Bybit, OKX, Deribit, Kraken, Bitfinex, Bitget, Gate, Hyperliquid, KuCoin, HTX, Crypto.com and Coinbase (open interest, funding, and the public liquidation feeds we collect), and our own USD price indexes. Each coin counts with the same values its own charts show. The series start on 24 October 2026, the first day our collection held every coin's open interest, funding, liquidations and price; a coin added later joins on the day its collection begins. A period appears once nine in ten of the coins have published it, so the open hour can trail by a few minutes. Venues we do not collect are not included, so totals understate the whole market.
