Solana ETFs have attracted $1.5 billion in inflows since their launch in July, despite a 57% drop in SOL's price, according to Bloomberg ETF analyst Eric Balchunas. Notably, half of these inflows are from institutional investors with over $1 billion in assets under management, as indicated by 13F filings. This suggests strong institutional interest and confidence in Solana's long-term potential, even amid challenging market conditions.
