Bitcoin ETFs Draw $2.95B as Inflows Extend to Eight Days
US spot Bitcoin ETFs attracted $2.95 billion over the past 30 days, extending their net-inflow streak to eight trading days. They recorded $31.07 million in inflows on Sept. 28, the weakest result of the run, as daily buying cooled after nearly $1 billion on Sept. 21 and $715 million on Sept. 22.
BlackRock’s IBIT led the latest session with $54.84 million in inflows. Grayscale’s GBTC recorded $23.19 million in outflows, while Fidelity’s FBTC lost $10.90 million. The current streak began on Sept. 17, shortly after Bitcoin ETFs saw $450.4 million in outflows following the US Senate’s failure to advance the Clarity Act.
Weekly Bitcoin ETF inflows later reached about $2.4 billion, the highest since October 2025. Bitcoin also moved above the estimated average ETF holder cost basis of $81,722, returning the typical investor to profit. Ethereum ETFs attracted $982.5 million over 30 days, while Solana and XRP funds recorded inflows of $278.2 million and $127.05 million. Sustained crypto ETF demand supports Bitcoin sentiment, but slowing daily inflows and continuing redemptions leave BTC vulnerable to volatility.
Bullish
The news is moderately bullish for BTC because Bitcoin ETF inflows have remained positive for eight consecutive trading days, with $2.95 billion entering the funds over 30 days. This suggests sustained institutional demand and has helped push Bitcoin above the estimated average ETF holder cost basis of $81,722, improving market confidence.
In the short term, strong cumulative inflows and the return of many ETF investors to profit could support buying momentum and reinforce bullish sentiment. However, the latest $31.07 million inflow was the weakest of the streak, while GBTC and FBTC recorded outflows. This slowdown could limit upside and increase the risk of profit-taking or consolidation, particularly if Bitcoin fails to hold gains.
Over the longer term, continued ETF adoption and inflows into Ethereum, Solana and XRP products indicate broader institutional interest in crypto assets. If these flows persist, they could provide structural support for BTC. Nevertheless, regulatory uncertainty, changing ETF flows and macroeconomic conditions remain key risks, so the bullish impact is supportive rather than a guarantee of a sustained breakout.
