Bitwise's Solana Staking ETF, ticker BSOL, crossed $1 billion of cumulative net inflows in late August, the first single U.S. spot Solana fund to do it, even as Monday's category print cooled to $925,010. That Monday figure was the weakest session of a 10-day inflow streak, down from $18.1 million on Friday. The milestone still stands. SoSoValue put BSOL's cumulative net inflows between $1.01 billion and $1.03 billion, about 77% to 80% of all capital that has ever gone into the nine U.S. spot Solana products. The fund launched on NYSE Arca on 28 October 2025 with a 0.20% fee. President Teddy Fusaro noted shares were about 40% below listing while SOL itself sat about 60% off its high. Investors kept sending dollars anyway. The yield is the reason they give.
BSOL holds Solana and stakes 100% of it, passing network rewards to shareholders. Historical staking yields on Solana have averaged around 7%. Recent fund commentary has cited about 5.80%. Assets under management are a different file. InflowScan put AUM near $965 million on 28 August after a $40.2 million creation. Earlier last week the holdings were closer to $760 million to $770 million. The gap is the 2026 drawdown. Dollars in minus redemptions can be $1 billion while the bag is worth less. Buyers as a group are still underwater on principal. The coupon narrows that hole. It does not close it. Goldman Sachs has been disclosed as the largest known institutional holder, with one filing putting the stake near $88.1 million. Combined AUM across the nine funds is about $1.49 billion. Category cumulative inflows sit above $1.3 billion.
Monday's $925,010 is the tell, not the trophy
A 10th green session at under $1 million is a bid that paused. Friday's $18.1 million and 27 August's $60.91 million, of which BSOL took $40.2 million, or 66%, were the heat. See how Ether funds kept an 11-day streak at $88 million a day. Solana is high-beta to that tape. If Tuesday copies Monday's trickle, the $1 billion inflow badge is historic and the near-term flow is not. If BSOL takes another $40 million clip, the yield product is still the allocator default inside the Solana wrapper.
Yield inside the ETF is the product now
Spot Bitcoin and most Ether funds pay no coupon. BSOL does. That is why money arrived through a year when the token fell. It is also why a weak Monday matters: if the yield is the sale, a pause in creations says the sale is rate-path sensitive too. Warsh's hike odds near 60% raise the hurdle for any coupon-bearing crypto fund. For the 21Shares Polkadot staking product that went live last week after costly payouts, see how TDOT's Q2 staking cash compared with DOT sales. A billion dollars of inflows is conviction. It is not a floor under $103 Solana.
