Bitcoin ETFs log best day in a month, add $524 million as cumulative trading volume approaches $1.5 trillion

The U.S. spot bitcoin exchange-traded funds bounced back to add $524 million worth of net inflows on Tuesday — the largest daily figure since just after the cryptocurrency hit all-time highs of around $126,000 on Oct. 6.

BlackRock's IBIT dominated the inflows with $224.2 million, followed by Fidelity's FBTC with $165.9 million, Ark Invest's ARKB with $102.5 million, Grayscale's BTC with $24.1 million, and Bitwise's BITB with $7.3 million, according to data compiled by The Block. The remaining funds saw zero flows for the day.

Since launching in January 2024, the Bitcoin ETFs have attracted total net inflows of $60.8 billion, with cumulative trading volume in that time now approaching the $1.5 trillion milestone.

The inflows come despite bitcoin dropping roughly 3% on Tuesday to around $103,000. However, the foremost cryptocurrency has recovered somewhat in early trading on Wednesday, currently changing hands for $104,724, according to The Block's BTC price page.

The worst 30-day flow period since March

Ahead of Tuesday, the ETFs had faced a period of cooling demand following the historic Oct. 10 deleveraging event, K33 Head of Research Vetle Lunde noted in a new report, with 30-day flows standing at -29,008 BTC — marking the worst 30-day flow since March 2025 and weaker flows than any period in 2024.

"While recent net flows are negative, ETP flows tend to move in waves, and periods of outflows tend to be short-lived compared to periods of inflows," Lunde said. "We view the recent sale pressure from ETF owners as a temporary reflection of derisking and expect 30-day flows to trend higher from here, with 30-day flows of -29,008 BTC marking the bottom for H2 2025."

BRN Head of Research Timothy Misir told The Block that while the renewed Bitcoin ETF inflows are encouraging, the longer pattern shows "cautious, episodic demand" rather than a sustained bid. "The recovery requires broader, consistent spot flows to break the $108,000–$110,000 battleground," he said.

Mixed picture for altcoin ETFs

Meanwhile, the U.S. Ethereum ETFs saw net outflows of $107.1 million on Tuesday, led by Grayscale's ETH product with $75.7 million, adding to a largely negative streak totalling nearly $615 million so far this month.

In contrast, the new U.S. spot Solana ETFs brought in another $8 million worth of net inflows on Tuesday, with Grayscale's GSOL topping Bitwise's BSOL for the first time, adding $5.9 million and $2.1 million, respectively. Cumulative Solana ETF inflows since they began trading on Oct. 28 stand at around $350.5 million.

The recently launched U.S. spot HBAR and Litecoin ETFs generated zero flows for the day, attracting a modest $71.1 million and $4.5 million in cumulative net inflows since their Oct. 28 debut, per SoSoValue data.
