A looming U.S. government shutdown could delay the approval of cryptocurrency ETFs for Solana (SOL) and Litecoin (LTC). Asset managers have been revising their S-1 registration statements with the SEC, but a shutdown would halt most regulatory activities. The SEC has requested exchanges to re-submit 19b-4 filings under new standards, indicating possible approval. However, with the deadline for the Litecoin ETF decision set for October 2, uncertainty looms if Congress does not pass a funding bill by midnight Saturday.
