What is Bitcoin open interest?

BTC open interest is the total notional value of Bitcoin perpetual positions that remain open across the exchanges PerpDEX Wars tracks. Unlike trading volume, which measures how much is traded over a period, open interest measures the value still tied to active positions.

The Bitcoin open interest chart shows how aggregate OI changes over the selected period, while the exchange table breaks current open interest down by venue and shows 24-hour and 7-day changes. This makes it easier to see where leverage is building, shrinking or becoming concentrated across the market.

Changes in BTC OI are most useful when read alongside price, funding rates and liquidations. Rising open interest means the value of outstanding positions is increasing, while falling open interest means positions are being reduced or closed. The page also shows how much of total tracked Bitcoin open interest sits on PerpDEXs versus the broader exchange market.

Frequently asked

What is BTC open interest?

BTC open interest is the total notional value of Bitcoin perpetual positions that are currently open. It measures outstanding market exposure rather than the amount traded during a given period.

What does rising or falling BTC OI mean?

Rising BTC OI means the value of open positions is increasing, while falling OI means outstanding exposure is being reduced. Open interest alone does not show whether traders are bullish or bearish, so it is more useful when combined with price, funding rates and liquidation data.

Why compare Bitcoin open interest across exchanges?

The exchange breakdown shows where open positions are concentrated. A large change on one venue can have a different market impact from a broad increase across Binance, Bybit, Hyperliquid and other exchanges.

What does the Bitcoin open interest chart show?

The chart tracks aggregate Bitcoin open interest over time for the selected period. It helps show whether outstanding leverage has been building or unwinding and puts the current level in historical context.

How is Bitcoin PerpDEX share calculated?

PerpDEX share compares the combined BTC open interest on the decentralized perpetual exchanges tracked on this page with total BTC open interest across all tracked exchanges.
