Perpetual futures do not expire, so exchanges use funding payments to pull the contract price back toward the spot market. MetaMask’s 2026 guide explains the basic idea: when perpetuals trade above spot, longs often pay shorts, and when they trade below spot, shorts often pay longs. The details vary by venue, but the economic purpose is similar.
The trap is that funding looks tiny when quoted as an interval rate. A trader may see a small payment every few hours and ignore it, especially if the position is profitable on screen. With leverage, repeated funding payments become a real cost. A 20 times leveraged long that pays funding through a sideways market can lose account equity even if the coin barely moves.
Funding can also become a sentiment indicator. Very positive funding says traders are paying to stay long, which can be bullish during a clean trend but dangerous after a crowded move. Negative funding can show short demand, but it does not automatically mean a squeeze is coming. The better question is whether spot demand confirms the derivatives signal.
A funding-aware plan should record the funding interval, the estimated dailyized cost, the break-even price move needed to justify holding, and the event calendar around the next few payments. Traders running basis or cash-and-carry strategies also need to include borrowing costs, exchange risk and execution slippage, not only the funding rate shown on the screen.
Risk notice: Perpetual futures are leveraged derivatives. Funding rates can change quickly, and a strategy that earns funding can still lose money through price moves, liquidation, exchange outages or collateral volatility.
