## Perpetual Futures Open Interest

Perpetual futures open interest represents the total number of outstanding derivative contracts that have not been settled. Unlike traditional futures, perpetual contracts do not have an expiration date, allowing traders to hold positions indefinitely.

Open interest is a measure of the total capital committed to a specific direction in the market. An increase in open interest during a price rise suggests new money is entering the market, confirming the trend.

Conversely, if prices rise while open interest falls, it may indicate a short-covering rally that lacks sustained momentum. In the crypto ecosystem, open interest is a critical indicator of leverage levels.

High open interest relative to market capitalization indicates a highly leveraged market susceptible to volatility. Analysts track changes in open interest to understand the sentiment and positioning of traders.

It is a fundamental component of quantitative finance models used to assess systemic risk.
