According to data from The Block, CME Ethereum futures options trading volume reached $1.26 billion in May. This is a significant increase from the $615.75 million trading volume in April and sets a new record high for monthly trading volume.
According to Wednesday's Wintermute market update, the number of open Ethereum futures contracts on CME is close to an all-time high. Wintermute analysts said the increase in open interest shows that institutional investors are increasingly interested in trading Ethereum (relative to Bitcoin) in anticipation of the upcoming launch of an Ethereum spot ETF.
