US spot Solana ETFs recorded net inflows for 12 consecutive weeks, attracting more than $1.4 billion and lifting combined assets under management to approximately $1.62 billion. The week ending September 18 generated $60.7 million in net inflows, including nearly $47.6 million on Thursday. Bitwise's BSOL captured roughly 80% of category inflows since launch and held $1.145 billion in assets as of September 18, supported by a staking structure that passes SOL staking rewards to investors through Helius. Its net staking reward rate was 5.31% annually versus a 5.65% gross rate after fees and operating costs. During the same Sept. 14-18 U.S. trading week, spot Bitcoin ETFs recorded more precise net inflows of $6.2137 million. BlackRock's IBIT led with $121 million, bringing cumulative inflows to $64.120 billion, while Fidelity's FBTC drew $79.9348 million and reached $10.360 billion cumulatively. Solana products therefore attracted roughly 10 times Bitcoin ETFs' net capital from a much smaller asset base.
