Open Interest Tracker
Open interest across the perpetual markets that settle on Hyperliquid, the clearinghouse Entropy's io:ANTH and io:SNDK settle through. Find crowded trades, potential squeezes, and where capital is actually sitting.
What is open interest? Open interest is the total US-dollar value of perpetual positions that are still open, counted across every matched long and short on a market. Rising open interest means new capital is entering a trade; falling open interest means positions are being closed. One thing to watch on a builder-deployed market: the operator sets an open interest cap per asset. On 2026-08-26 the Hyperliquid API reported a $5M cap on io:ANTH (raised to that level on 2026-08-25) and a $10M cap on io:SNDK. Caps can be changed by the deployer, so re-check the live figures rather than trusting a screenshot. Figures below are denominated in USD and read from the Hyperliquid API on page load.
