Nine-Day Streak Walks So Close to August's Record, Almost Trips Over It 🏃

U.S. spot Bitcoin ETFs pulled in $66.19 million on Tuesday, extending their inflow streak to nine consecutive sessions and matching the nine-day run that ran from Aug. 17 to Aug. 27, according to Decrypt's Bitcoin ETF tracker. The current streak, which began on Sept. 17, has drawn roughly $3.08 billion, edging out the August run's approximately $3.04 billion total by about $33 million. Bitcoin changed hands near $84,400 on Wednesday, up roughly 1% on the day and recovering Monday's losses. The funds extended their streak to eight straight days on Monday with $31.07 million in net inflows, the weakest day of that stretch, according to SoSoValue. BlackRock's IBIT led with $54.84 million, while Grayscale's GBTC lost $23.19 million and Fidelity's FBTC shed $10.90 million.

Over the past 30 days, U.S. spot Bitcoin ETFs have accumulated $2.95 billion in net inflows, per SoSoValue. The run of green days started on Sept. 17, right after the worst stretch in months. On Sept. 15, Bitcoin ETFs lost $450.4 million, their biggest one-day outflow since June 24, the same day the U.S. Senate voted 49-50 against advancing the Clarity Act, which needed 60 votes. Ethereum ETFs lost another $142.3 million that day. The following week was subdued, with Bitcoin ETFs netting just $6.2 million, their smallest weekly inflow in 141 weeks. Then buyers returned rapidly. Sept. 21 brought in nearly $1 billion, the best day for the funds since October 2025, with another $715 million following on Sept. 22. Flows then cooled to $347 million on Sept. 23, $191 million on Sept. 24, and $134 million on Sept. 25, for a weekly total of about $2.4 billion, the biggest weekly haul since October 2025.

The rally has lifted $BTC above the average ETF holder's cost basis of $81,722, returning the typical fund investor to profit for the first time since January. $BTC was back above $84,000 on Monday and pushed above $85,000 during the week to a high of $85,000-plus before settling near $84,400. The current nine-day streak still trails the 13 consecutive days from June 2025. Matching that record would require inflows through Monday, Oct. 5. The previous nine-day run ended on Aug. 28, when the funds saw $201.9 million in outflows after Federal Reserve Chair Kevin Warsh spoke at Jackson Hole. U.S. spot Bitcoin ETFs took in $998.95 million on Monday one week earlier, according to SoSoValue, with BlackRock's IBIT drawing $381.37 million, Ark & 21Shares' ARKB adding $289.12 million, and Fidelity's FBTC contributing $238.84 million.

Other crypto ETFs also attracted capital. Ethereum ETFs added $982.5 million over 30 days and $17.1 million on Monday, per SoSoValue. Solana funds took in $278.2 million over the month, while XRP funds brought in $127.05 million. Bitcoin is up 7.33% this month, which would mark the best September in the Coinglass price tracker's history if the figure holds through the month's final session. September 2024 returned 7.29%, leaving the record essentially tied with one day remaining. $BTC is now about a third below its October 2025 record of $126,296, after recovering from a slide to about $75,000 the week the Federal Reserve raised rates by 25 basis points to 3.75%–4% on Sept. 16, its first hike since 2023, a move traders had priced at nearly 93% odds. The Federal Reserve's preferred inflation gauge, the PCE index, rose 0.3% in August and 3.4% from a year earlier, below the 0.4% and 3.7% economists expected, while core PCE rose 0.2% on the month and 3.0% annually, against forecasts of 0.3% and 3.3%.
