Cryptocurrency ETF capital flow on September 9: Altcoin funds attracted nearly US$59 million, and Bitcoin spot funds had a net outflow of US$120 million.
On September 9, Ethereum (ETH), Ripple (XRP) and Solana (SOL) related ETFs combined received a net inflow of nearly US$59 million, while U.S. spot Bitcoin funds lost approximately US$120 million on the same day. This data led to a clear asset differentiation trend in the capital flow of cryptocurrency ETFs that day.
Core Points
- Ethereum, Ripple and Solana ETF together attracted nearly US$59 million in net inflows.
- Bitcoin funds experienced a $120 million outflow.
- The above data all refer to the trading day of September 9.
Ethereum, Ripple and Solana ETFs attracted nearly US$59 million on September 9.
In September 9 transactions, these three types of altcoin ETF products together attracted nearly US$59 million. This figure covers the sum of Ethereum, XRP and Solana products, rather than the performance of a single asset.
According to SoValue's data, CryptoSlate reported that the net inflow of Ethereum ETF on that day was US$34.75 million, the net inflow of XRP products was US$12.29 million, and the net inflow of Solana ETF was US$11.73 million. These figures add up to $58.77 million, consistent with the description of "nearly $59 million."
It is worth noting that the above specific split data by asset classification comes from a secondary report, and detailed row data for ETH, XRP and SOL categories have not been independently restored in the original data. Recently, Ethereum products have gained strong momentum, recording the highest monthly net inflow since August 2025; in contrast, XRP funds have relatively flat funding, with net inflows of less than US$2 million in lighter trading days.
Bitcoin funds lost US$120 million on the same day
On September 9, the U.S. spot Bitcoin ETF recorded a daily net flow of US$-120.24 million. This marks an outflow of funds at the fund level rather than a decline in Bitcoin's price or market value. This is the second consecutive negative trading day after recording-46.65 million US dollars on September 8.

Comparison of Bitcoin outflows and total altcoin inflows
Bitcoin's capital outflows are slightly higher than the combined inflow of nearly US$59 million among the three types of altcoin ETFs. Adding these four sectors together, the overall market on the day showed a net outflow of approximately-61 million US dollars.
The sell-off was mainly concentrated at the specific fund level. The ARK21 Shares Bitcoin ETF (ARKB) contributed an outflow of-77.98 million US dollars, while the Morgan Stanley Bitcoin Trust (MSBT) achieved a positive inflow of 4.49 million US dollars. Currently, the net assets of the Bitcoin ETF are US$99.33 billion, and the average daily transaction value is US$2.05 billion. Despite the volatility, these one-day changes have not reversed Bitcoin's previous inflow trend of more than US$700 million for several consecutive days.
Interpretation of a snapshot of crypto ETF fund flows on September 9
Single-day data is not enough to establish long-term trends
Opposite fund flows on a single trading day do not prove that investors have shifted capital from Bitcoin funds to Ethereum, XRP or Solana products. The aggregated traffic data cannot identify specific investor-level transfers, and relevant analysts do not claim that funds have moved directly between these products.
The data on September 9 is not the total statistics of the entire crypto ETF market, and a single trading session cannot define long-term trends. There have been pattern reversal in previous trading days, such as the Bitcoin ETF rebounded when the winning streak of Ethereum and XRP ended, highlighting the rapid shift in market dominance every day.
As another real-time indicator of market sentiment, the Fear and Greed Index at the time of writing is at 69 points, in the "greedy" range. It should be noted that this reading is independent of the September 9 ETF trading day data. In the next 24 to 72 hours, we need to focus on whether Bitcoin ETF will experience a third consecutive outflow and whether the altcoin category can maintain its total inflow trend.
