According to Odaily Planet Daily, data from The Block showed that CME Ethereum futures options trading volume reached US$1.26 billion in May, a significant increase from US$615.75 million in April, setting a record high for monthly trading volume. According to Wednesday’s Wintermute market update, the number of open Ethereum futures contracts on CME is near an all-time high. Analysts at Wintermute said the increase in open interest indicates that institutional investors are increasingly interested in trading Ethereum (relative to Bitcoin) in anticipation of the upcoming launch of an Ethereum spot ETF.
