BTC: Kraken Perpetual Open Interest
Shown as its 13–19 Mar 2023 sample; the latest readings and full history are included with Plus.
USD value of open BTC perpetual positions on Kraken (all its BTC perpetuals together), one side of each position.
Why use it. A single venue's open interest with a longer history than our cross-venue charts, which start when our own collection began in October 2026: rising open interest means leverage entering the market, falling open interest positions closing. How to read it. Read the changes alongside price: price up with open interest up suggests new leveraged positions; a sharp drop marks liquidations or mass closing. One venue only, so compare its trend, not its level, with the cross-venue charts.
Calculation. Each period takes every Kraken BTC perpetual's open interest at the period's close and sums them in USD: inverse contracts at their USD face value, linear contracts in coins valued at the closing mark price. Before our own collection of Kraken began, the values are Kraken's published hourly figures (served from March 2023); from then on they are our own minute-by-minute collection of the same figures. Source: the public open-interest history Kraken publishes for all its BTC perpetuals, read once by us on 7 November 2026: hourly figures from 7 March 2023, with its hourly mark prices (each contract from its listing if later). It is joined to our own collection of Kraken's public futures data from 14 October 2026. Kraken alone: other venues are not included, nor contracts Kraken no longer lists.
