BitMEX Positions

BitMEX invented the perpetual swap, and its XBTUSD contract was for years the price-discovery centre of Bitcoin derivatives. This page is planned to track position distribution and large-position changes on BitMEX, reading the positioning structure of a venue whose historical influence still lingers.

BitMEX's share has fallen from outright dominance in 2019 to low single-digit percentages, so its absolute open interest carries less information than it once did. As a flagship inverse (coin-margined) venue it remains useful for understanding coin-margined leverage — where collateral value shrinks as price falls, mechanically amplifying liquidation cascades. When comparing venues, do not mistake BitMEX's shrinking share for market-wide deleveraging.

Volume and market-structure metrics describe the size and distribution of trading activity. Methodologies differ sharply between venues (wash-trading filters, USD conversion), so confirm the accounting basis before comparing platforms side by side.

BitMEX's flagship XBTUSD is an inverse contract: each contract is worth one US dollar, while margin and P&L settle in bitcoin. This construction produces a convexity that stablecoin-margined traders never face. As price falls, the BTC collateral backing every position is itself losing dollar value, so losses accelerate non-linearly and liquidation cascades on inverse venues are mechanically harsher. That is why coin-margined open interest deserves separate tracking rather than being folded into a single aggregate. Reading BitMEX positioning today is mostly about the composition of legacy leverage: accounts that prefer inverse contracts skew toward long-tenured, coin-collateralised traders whose behaviour differs from the stablecoin majority. The March 2020 episode, when BitMEX liquidations drove the global market until its circuit breaker paused the engine, remains the canonical illustration of how one venue's liquidation mechanics can briefly set the worldwide price, and it is the context in which this dataset is usually cited.

The live chart for this metric is still being wired up. Global volume, venue share and perp-vs-spot pages already carry real data.
