The Crypto ETF Inflow Update shows a quieter end to September, with Bitcoin, Ethereum, XRP, and Solana exchange-traded funds still recording positive flows but at noticeably lower levels. Data for September 28 suggests investors have not abandoned fund products, although daily demand has cooled from stronger readings earlier in September. Bitcoin posted $31.07 million in net inflows, Ethereum attracted $17.10 million, XRP added $3.96 million, and Solana recorded $12.70 million.
Bitcoin ETF Demand Slows
Bitcoin ETFs recorded their smallest inflow of September at $31.07 million, according to SoSoValue data. Cumulative net inflows reached $57.58 billion, while ETF trading value stood near $2.05 billion. Total net assets were $107.82 billion, equal to 6.42% of Bitcoin’s market capitalization.
BlackRock led inflows with $54.84 million, while Grayscale added $10.32 million. Strategy purchased 1,665 BTC for $142.66 million at an average price of $85,681. Its total Bitcoin holdings reached 847,666 BTC.
Bitcoin traded around $83,165.34, with a market capitalization near $1.673 trillion and 24-hour volume of $38.02 billion.
Ethereum ETF Inflows Remain Positive
The Crypto ETF Inflow Update also highlights softer Ethereum demand. Ethereum ETFs recorded $17.10 million in daily net inflows, the second-lowest September figure. Cumulative inflows reached $13.96 billion, while total net assets stood around $17.69 billion, representing 5.40% of Ethereum’s market capitalization.
BlackRock contributed $15.35 million, followed by 21Shares with $1.74 million. SharpLink Gaming also staked another 42,074 ETH worth approximately $112.8 million. Its reported holdings reached 892,127 ETH, alongside substantial staking rewards.
Ethereum traded around $2,670.54, with a market capitalization of approximately $326.05 billion.
XRP ETF Demand Turns Quiet
XRP recorded the weakest daily inflow among the four assets. Its ETFs attracted only $3.96 million on September 28, the third-lowest September reading. Cumulative inflows reached $1.79 billion, while total net assets stood at $1.68 billion, equal to 1.79% of XRP’s market capitalization.
Canary Capital supplied the entire daily inflow. XRP traded around $1.49, with a market capitalization near $93.63 billion and 24-hour trading volume of about $3.81 billion.
Solana Shows Relative Strength
The Crypto ETF Inflow Update shows Solana delivering a stronger daily result. Solana ETFs attracted $12.70 million, taking cumulative inflows to $1.62 billion. Total net assets reached $1.93 billion, representing 2.76% of Solana’s market capitalization.
Bitwise led with $9.65 million, while Canary Capital added $5.04 million. Solana traded around $118.05, with a market capitalization near $69.39 billion.
Upcoming ETF Developments
Another ETF development involves regulatory and product changes. REX Shares and Osprey Funds updated a Staked SEI ETF filing with the SEC on September 28, with October 23, 2026, listed as the effective date.
The report also discussed an IRS notice involving 351 exchange ETFs. Analyst Eric Balchunas said the notice could affect funds operating near existing regulatory boundaries, although he was still reviewing the details.
These figures show why fund flows need context, because one session can reflect temporary positioning rather than lasting changes in investor demand.
Conclusion
The Crypto ETF Inflow Update points to cooling demand rather than a complete withdrawal. Bitcoin and Ethereum continue to attract substantial cumulative capital, XRP remains comparatively quiet, and Solana shows stronger daily inflows. Investors should monitor fund flows, regulatory developments, trading volumes, and broader crypto market conditions together. Daily inflows can change quickly, so the figures provide a snapshot rather than a guarantee of future performance.
