U.S. spot Solana ETFs recorded their largest weekly inflows to date, drawing $188 million in new capital as all seven funds posted positive flows. Bitwise’s BSOL captured approximately two-thirds of the weekly total.

The funds also reached a new daily high on Friday, when combined inflows reached roughly $87 million.

BSOL accounted for about $128 million of the weekly figure across the five trading sessions through Sept. 25. Grayscale’s GSOL attracted approximately $28 million, while Fidelity’s FSOL brought in $18 million, according to weekly figures shared by Solana’s official account.

The other $14 million was distributed among Morgan Stanley, VanEck, Franklin Templeton and 21Shares.

Friday Marks a New Daily High

Friday’s $87 million inflow represented nearly half of the entire weekly amount and marked the strongest one-day intake since the ETFs began trading.

Bitwise accounted for approximately $56 million of Friday’s total, while Grayscale attracted another $19 million.

Spot Solana ETFs give investors a way to gain exposure to SOL through brokerage accounts without directly holding the asset or managing a crypto wallet.

Net inflows measure new money entering the funds after withdrawals and are different from the trading volume generated when investors buy and sell ETF shares among themselves.

BSOL Leads Cumulative Inflows

Bitwise continues to account for most of the capital entering Solana ETFs.

BSOL has attracted approximately $1.2 billion from the roughly $1.6 billion in combined cumulative net inflows across the seven funds, representing about 76% of total demand since launch.

Its share of inflows during the latest week was lower at around 68%, with rival products collectively attracting approximately $60 million.

Crypto ETF Demand Remains Broad

The weekly inflows were part of a broader increase in demand for U.S. crypto investment products.

Bitcoin ETFs collected roughly $2.4 billion during the same period, while ether ETFs brought in approximately $690 million, based on CoinDesk’s calculations using Farside’s daily flow data.

SOL traded around $119 during Monday’s Asian morning session, remaining roughly 60% below its all-time high near $293.

Alpenglow Reaches Second Test Environment

Solana’s strong ETF flows coincide with continued development work on Alpenglow, an upgrade designed to accelerate transaction finality.

The proposed upgrade seeks to reduce the time needed for transactions to become irreversible from approximately 12.8 seconds to about 150 milliseconds.

Alpenglow entered its second public testing environment on Friday. The 150-millisecond figure remains a development target, and no mainnet launch date has been announced.
