A crypto funding rate heatmap is a colour-coded grid that shows the funding rate of many coins across many exchanges at a single glance — so you can instantly spot where the market is paying the most to hold a position.
Funding rates change every few hours and there are thousands of them across 17 exchanges. Reading them as a long list is hopeless; a heatmap turns that flood of numbers into a picture — green where longs pay shorts, red where shorts pay longs, and the deeper the colour, the more extreme the rate. This guide explains how to read a funding rate heatmap, what the hot cells actually mean, and how to turn them into market-neutral income.
On perpetual futures there is no expiry date, so exchanges use a small recurring payment called the funding rate to keep the perpetual price tied to spot. When the rate is positive, longs pay shorts; when it is negative, shorts pay longs. It is paid every 8, 4 or 1 hour depending on the exchange. If you are on the receiving side, that payment is income — and a heatmap is how you find the biggest ones fast. New to this? Start with funding-rate arbitrage explained.
Picture a grid: coins down the side, exchanges across the top, and every cell coloured by that coin’s funding rate on that exchange. Here is an illustrative snapshot:
| Coin \ Exchange | Binance | Bybit | OKX | Gate |
|---|---|---|---|---|
| BTC | +9% | +11% | +8% | +10% |
| ETH | +12% | +7% | +10% | +9% |
| SOL | +24% | +19% | +22% | +16% |
| SPELL | -596% | -540% | -610% | -575% |
| TLM | -372% | -355% | -361% | -349% |
| BONK | +210% | +188% | +205% | +176% |

| You see | What it means | The market is saying | How you'd collect |
|---|---|---|---|
| 🟩 Green cell | Positive funding — longs pay shorts | Crowded with longs (bullish) | Short the perp, hedge with spot |
| 🟥 Red cell | Negative funding — shorts pay longs | Crowded with shorts (bearish) | Long the perp, hedge the other side |
| Deep colour | Extreme rate (far from zero) | Very one-sided positioning | Biggest carry — but check the risk |
| Pale / white | Near-zero funding | Balanced book | Little to harvest here |
The one rule
A heatmap shows the funding, not your profit. Your real return is the funding you collect minus trading fees on both legs and any slippage. Always read the net number before acting — the brightest cell isn’t always the best trade after costs.
An extreme cell is a crowd. A deep-green +200% cell means traders are piling into longs and paying dearly to stay long — so the market will pay you to take the other (short) side, while you stay price-neutral by holding the coin on spot. A deep-red −596% cell means shorts are crowded and paying longs. Either way, the heatmap is pointing at where positioning is stretched and the carry is richest.
This is exactly the delta-neutral strategy — the heatmap is just the fastest way to find the richest funding to harvest. For the mechanics, see funding-rate arbitrage strategy and size it with the funding-rate calculator.
A screenshot of funding rates is stale within hours — the whole point is that extreme cells revert as positioning unwinds. A useful heatmap is live: it re-colours every funding cycle, ranks by real (net-of-fee) carry, and tells you exactly when each rate pays. That is the difference between spotting an opportunity and catching one.
ArbiScreen’s Funding Radar is a real-time funding heatmap across 17 exchanges. It surfaces the most extreme funding rates, shows the delta-neutral direction to collect them, calculates the net return after fees, and runs a live countdown to each payout — plus Pro alerts the moment a rate turns extreme. No stale screenshots, no manual math.
