US spot Solana ETFs pull in $26M in a single day as BSOL continues its dominance
Bitwise's staking-enabled Solana ETF accounted for more than half the day's inflows, extending its grip on roughly 80% of cumulative category flows.
US spot Solana ETFs just logged their strongest single-day performance yet, pulling in $26.1 million in net inflows on September 21. Bitwise’s BSOL led the pack with $14.4 million, while Grayscale’s GSOL added another $7.8 million. The rest of the field split what was left.
That $26.1 million figure pushed cumulative inflows for the entire Solana ETF category past $1.4 billion, with combined net assets now sitting at roughly $1.74 billion.
BSOL’s staking edge keeps compounding
Bitwise launched BSOL on October 28, 2025, and the product has since accumulated over $1.1 billion in cumulative net inflows. That’s approximately 80% of all money that has flowed into US spot Solana ETFs, period.
BSOL is structured as a staking product, meaning it targets Solana network rewards on behalf of holders. Even as Grayscale, Fidelity, and VanEck have rolled out their own Solana ETF products, BSOL’s first-mover advantage combined with its staking mechanics has kept it firmly in the lead. Grayscale’s GSOL managed a respectable $7.8 million on the same day, but that still left it at barely half of BSOL’s haul.
What’s driving the broader Solana ETF wave
The September 21 figures extended what has been a multi-week stretch of positive inflows into the category. Previous single-day highs had already reached $10.19 million and $33.5 million in prior weeks before the September 21 record.

The competitive landscape is getting crowded, but not evenly
Bitwise, Grayscale, Fidelity, and VanEck all have products live. BSOL’s 80% share of cumulative inflows is the kind of market concentration that tends to be self-reinforcing. Larger asset bases mean tighter spreads, better liquidity, and more visibility on institutional platforms.
Grayscale’s GSOL has carved out a meaningful niche, and its brand recognition from the legacy GBTC trust gives it distribution advantages that most rivals can’t match. Fidelity and VanEck bring their own institutional relationships and distribution muscle. None of them have matched BSOL’s staking feature, and BSOL also benefited from a temporary fee waiver designed to attract new investors at launch.
If September continues at this pace, the month could meaningfully accelerate the category’s path toward the $2 billion net asset milestone.
