Open Interest
Total notional value of all open futures positions at a given moment.
BTCUSDT open interest is up 1.6% over the last 24 hours. The biggest OI gainer among 90 tracked Binance perps is USELESS (+57.7%), the biggest drop is RAM (-36.3%).
Open interest (OI) counts every contract that has been opened but not yet closed. Rising OI while price rises usually means new buyers are entering (bullish momentum). Rising OI while price falls means new shorts piling in. Falling OI means positions are being closed. A sudden OI spike without price movement is almost always leverage buildup that will resolve violently. We track 1h / 4h / 24h OI delta on every top-30 Binance USDT-M perpetual.
Open Interest FAQ
What is open interest in crypto?
Open interest (OI) is the total value of all futures contracts that have been opened but not yet closed. Unlike volume, which counts turnover during a window, OI measures how much leveraged exposure is currently live in the market.
What is Bitcoin's open interest change today?
Whenever fresh data is available, the live panel on this page shows BTCUSDT's 24-hour open interest change plus the biggest OI gainers and losers across tracked Binance USDT-M perps, refreshed roughly every 15 minutes.
What does rising open interest mean?
Direction comes from pairing OI with price: rising OI while price rises means new longs are entering; rising OI while price falls means new shorts are piling in; falling OI in either direction means positions are being closed rather than opened.
Why do sudden open interest spikes matter?
An OI spike without a matching price move is leverage building up on both sides. That buildup usually resolves violently, as one side gets liquidated once price picks a direction. Reading OI spikes together with funding shows which side is paying to hold the risk.
Open interest vs volume: what is the difference?
Volume counts every contract traded during a period, so it resets each window and double-counts churn. Open interest is a snapshot of contracts still open right now. High volume with flat OI is churn; modest volume with climbing OI is genuine new positioning.
