The U.S. Securities and Exchange Commission (SEC) recently announced the postponement of its approval decisions for several spot cryptocurrency ETFs, including Grayscale's Hedera, Franklin's Solana, and Bitwise's Dogecoin ETF, with new decision dates set for June 10-11, 2025. This move has raised concerns in the market about regulatory uncertainty. The SEC also delayed Fidelity's Ethereum ETF staking feature and Invesco Galaxy's physical subscription and redemption mechanism for Bitcoin and Ethereum ETFs. Bloomberg ETF analyst James Seyffart expects more related applications to be postponed this week, with the final deadlines for most products likely extended to October 2025 or later.
