Since August 2025, Ethereum's Open Interest has been in a relentless decline. Falling from $33.1 billion to $10.4 billion, it has been cut by three, illustrating how severely derivatives were hit by this correction.

This contraction in Open Interest stems from a combination of factors: forced liquidations, falling prices compressing the value of open positions, and voluntary closures.

Given the broader environment, one that remains largely unfavorable to risk-taking, the lack of confidence and interest among market participants is unsurprising, and shows clearly through this metric.

Comparing the leading platforms, Binance holds the highest Open Interest at $4.2 billion, ahead of Gate.io at $1.9 billion and OKX at $1.4 billion. Despite a broad-based decline across all exchanges, Binance's market share has just crossed the 40% threshold, confirming its dominant position in ETH derivatives even during a downturn.

In a derivatives market that continues to contract, Binance keeps asserting its status as the leader in this space.

Derivatives markets nonetheless still represent significantly larger volumes than spot markets or ETFs, and will likely be the first sector where a renewed appetite for risk could shift the current dynamic.
