The U.S. Securities and Exchange Commission (SEC) is experiencing a surge in cryptocurrency ETF filings, with at least five new submissions this week. The ongoing government shutdown has stalled the review process, leaving numerous applications pending. Among the latest filings, VanEck has proposed a Lido Staked Ethereum ETF, while 21Shares and ARK Invest have also submitted new proposals. Analysts are describing the situation as a 'land rush' for crypto ETFs, driven by record inflows and increasing investor interest.
