Bitwise's share of Solana ETF inflows slipped on the category's record $80 million day
Bitwise's BSOL drew $55.7 million of US spot Solana ETFs' record $80 million to $87 million day, a smaller share than its 76% to 80% of all inflows. Grayscale and the smaller funds took a bigger slice of the new money than of the old.

What happened
- US spot Solana ETFs took in about $80 million to $87 million on September 25, more than double the $33.5 million single-day record set in August.
- Since the funds launched on October 28, 2025, BSOL has collected around $1.22 billion of more than $1.6 billion in cumulative inflows, a share the source puts at about 80%.
- Weekly inflows across the category reached $181 million, according to Crypto Briefing.

Why it matters
- contradiction The source's own dollar figures cap Bitwise's cumulative share at 76%, so its lead is a few points smaller than the 80% figure used to describe it.
- decision Grayscale, Fidelity and Morgan Stanley are the ones who have to decide whether to change fees or staking terms; Bitwise can leave its own alone while it holds $1.22 billion.
- constraint If every fund stakes, yield explains why allocators pick a Solana fund over a Bitcoin fund and cannot by itself explain why they pick Bitwise's.
Bitwise's lead is large under either of the source's figures. Around $1.22 billion of $1.6 billion is 76% [1] (at most, because the source says cumulative inflows have crossed $1.6 billion [4]), and an 80% share would require about $1.28 billion [10].
On the record day the share ran lower. BSOL's $55.7 million was 64% to 70% of the $80 million to $87 million that arrived on September 25, depending on which end of the range holds [2]. Everyone else took $24.3 million to $31.3 million, or 30% to 36% of the day [4]. Since launch, the same group has taken about $380 million, roughly 24% of the total [3]. Grayscale's GSOL supplied about $18.5 million of the day's non-Bitwise money, leaving $5.8 million to $12.8 million for Fidelity's FSOL, Morgan Stanley's MSOL and any other funds [8][5].
Crypto Briefing credits staking for the demand. The funds earn yield by staking the SOL they hold, a return Bitcoin ETFs cannot structurally offer, according to the publication [9]. It describes institutional appetite for staking-enabled funds as accelerating [12]. The same article says the category could become more competitive if Grayscale, Fidelity or Morgan Stanley "adjust their fee structures or staking strategies" [11]. A rival with a staking strategy to adjust is presumably staking already. In that case staking explains why an allocator buys a Solana fund instead of a Bitcoin fund, and explains little about why the allocator picks Bitwise's. The article does not give fees, staking yields or holder data for any of the funds, so the flows cannot show whether the buyers are institutions.
Crypto Briefing calls the week the peak of a sustained multi-week trend [13]. The record session supplied 44% to 48% of the week's $181 million [6]. The other sessions shared $94 million to $101 million [7].
I see three ways this goes. BSOL's first-year head start keeps compounding, particularly if category assets, now $1.8 billion to $1.96 billion, pass the $2 billion mark the source says could draw a new wave of buyers [5][14]. The rivals could instead change fees or staking terms and keep taking a third of the heavy days, so Bitwise's share of the total drifts toward two-thirds [2]. A third possibility is that the surge was buying with SOL near $120, well below its high, and fades once the price moves [10]. Meanwhile Bitwise, holding $1.22 billion of the category's inflows, faces nothing in these figures that would push it to cut fees [7]. The pressure sits with the three rivals splitting the rest.
The evidence supports concentration, with Bitwise holding about three-quarters of the money [1], and it supports demand, with the record day at 2.4 to 2.6 times August's high [8]. It does not support consolidation at the margin. On the one day the source breaks down by fund, new money was less concentrated than old money [2][4]. The consolidation thesis fails if Bitwise's share of heavy days stays near two-thirds, and it holds if the next few big sessions put that share back above 76% [1].
What to watch
- BSOL's share of the next several heavy inflow days, measured against its 76% share of cumulative money.
- Any fee cut or change to staking terms from Grayscale, Fidelity or Morgan Stanley.
- Whether category assets pass $2 billion, and whether daily flows hold if SOL moves away from $120.
