The latest data from the U.S. Commodity Futures Trading Commission (CFTC) shows that hedge funds are shorting Ethereum positions worth $1.73 billion on the Chicago Mercantile Exchange (CME), with leveraged net positions showing a significant short bias. This operation is regarded as a typical basis trading strategy, where traders short $ETH contracts on the CME while buying spot ETFs to achieve Delta neutrality and obtain an annualized return of approximately 9.5%. In addition, if traders choose to buy spot $ETH and stake it, they can also obtain an additional annualized return of approximately 3.5%. However, it is worth noting that the current Ethereum spot ETF does not support staking, so additional returns cannot be achieved. Overall, this type of arbitrage strategy has attracted a lot of institutional attention, given that the total assets under management of spot ETFs are approximately $12.00 billion.
