Recent 13F filings show that both Morgan Stanley and Citadel Advisors increased their Solana exposure in the first quarter through Bitwise ETF products rather than direct token ownership. Morgan Stanley raised its position in Bitwise’s Solana Staking ETF to $29.9 million from $15.3 million, while Citadel Advisors increased its Bitwise Solana ETF exposure to $22.3 million from $2.6 million, a reported 760% increase. The disclosures highlight continued institutional interest in Solana-linked investment vehicles offered through regulated fund structures.
