JPMorgan Chase disclosed its first reported position in a Solana-linked exchange-traded fund through a $523,000 stake in the Bitwise Solana Staking ETF, according to its first-quarter 13F filing. The disclosure indicates the bank gained exposure to Solana through an ETF structure rather than by directly holding the token. A 13F filing is a quarterly U.S. regulatory disclosure that shows certain institutional investment holdings, making it a closely watched source for shifts in professional investor exposure to digital asset products.
