Solana ETFs just had their biggest day yet. On September 21, US spot products brought in a combined $26.1 million in net inflows, giving the fast-growing category its strongest single-day showing so far.
Bitwise’s BSOL did most of the heavy lifting, attracting $14.4 million on its own. Grayscale’s GSOL followed with $7.8 million, while Fidelity, VanEck and the other products divided what remained.
The latest inflows pushed the category beyond $1.4 billion in cumulative net inflows. Together, the funds now hold roughly $1.74 billion in net assets.
That puts one product conspicuously ahead of the others.
Solana ETFs Have a Clear Front-Runner
Bitwise launched BSOL on October 28, 2025, with a staking feature built into the product. Since then, it has collected more than $1.1 billion in cumulative net inflows — around 80% of all money flowing into US spot Solana ETFs.
The staking structure is central to the product. Rather than simply tracking Solana, BSOL is designed to seek rewards from the network on behalf of its holders.
That has helped distinguish it as more products entered the US market. Grayscale, Fidelity and VanEck have all launched their own Solana ETFs, but none has matched BSOL’s staking setup.
Grayscale’s GSOL is still attracting meaningful interest. Its $7.8 million haul on September 21 was substantial, but it remained well behind BSOL’s $14.4 million.
The broader category has also been building momentum for weeks. Before September 21, other single-day inflow records had reached $10.19 million and $33.5 million during the previous few weeks.
Why BSOL Keeps Pulling Ahead
A crowded market does not necessarily mean evenly distributed attention.
BSOL’s roughly 80% share of cumulative inflows gives it an increasingly large asset base, which can reinforce its position through greater liquidity, tighter spreads and more visibility across institutional trading platforms.
Grayscale has another advantage of its own. GSOL benefits from the company’s established brand and distribution reach, including recognition built through its legacy GBTC trust.
Fidelity and VanEck also arrive with institutional relationships and established distribution networks. But so far, none has combined those advantages with the staking feature offered by BSOL.
Bitwise also used a temporary fee waiver when the fund launched, giving early investors another reason to take a closer look.
For Solana ETFs, that combination of first-mover momentum, staking and scale has produced an unusually concentrated market.
And with the category already above $1.4 billion in cumulative inflows, the next milestone is starting to come into view. If September’s pace continues, Solana ETFs could move materially closer to $2 billion in net assets.
