U.S. spot exchange-traded funds that track Solana (SOL) recorded a historic week of capital inflows, pulling in $188 million across all listed products. The momentum came as investors sought exposure to the blockchain without handling private keys, and it unfolded while the network’s developers were trialing a major performance upgrade.
Record-breaking weekly inflows
During the five trading sessions ending on September 25, every Solana-linked ETF registered positive net additions, culminating in a combined $188 million of new money. The bulk of the activity occurred on Friday, when the funds together added roughly $87 million— the largest single-day contribution since the products launched. This surge pushed the cumulative net inflows for the Solana ETF family to $1.6 billion.
Bitwise’s overwhelming share
Bitwise’s BSOL fund emerged as the clear leader, drawing about $128 million, which translates to roughly 68% of the week’s total. Over the life of the Solana ETF suite, Bitwise has amassed around $1.2 billion in net inflows, accounting for about 76% of the aggregate figure. Competing products—Grayscale’s GSOL, Fidelity’s FSOL, and funds from Morgan Stanley, VanEck, Franklin Templeton and 21Shares—combined for the remaining $60 million of the week’s flow.
Network upgrade adds context
The inflow spike coincided with the public testing phase of Solana’s Alpenglow upgrade. Designed to slash transaction finality from roughly 12.8 seconds to an anticipated 150 milliseconds, the upgrade aims to make the chain competitive for high-frequency use cases. Although the live rollout date has not been announced, the testing milestone reached on Friday may have bolstered investor confidence, prompting the influx of capital.
Parallel trends in crypto ETFs
The Solana surge unfolded alongside robust activity in other crypto-focused exchange-traded products. U.S. Bitcoin ETFs accumulated about $2.4 billion in net inflows over the same week, while Ether-linked funds added close to $690 million. These figures suggest a broader appetite for regulated, brokerage-based exposure to digital assets.
Why it matters
The unprecedented weekly inflow into Solana ETFs underscores growing institutional and retail interest in diversified, custodial-free exposure to emerging layer-1 blockchains. Bitwise’s dominant market share highlights the importance of brand recognition and product accessibility in this nascent segment. Meanwhile, the concurrent testing of the Alpenglow upgrade signals that technological advancements continue to drive market sentiment, potentially setting the stage for further capital allocation as Solana’s performance metrics improve.
