ETH: CFTC Largest Traders' Share of Open Interest
Shown as its 2–31 Oct 2026 sample; the latest readings and full history are included with Plus.
The share of the open interest in CME's Ethereum futures (50 ETH a contract) held by its 4 and 8 largest traders, on each side.
Why use it. A market held by a few traders can move sharply when one of them leaves; rising concentration on one side marks a crowded position. How to read it. Long lines above short lines mean the biggest positions are long. A sudden drop in one line means a large trader closed or cut a position.
