Summary
BlackRock's iShares Bitcoin Trust (IBIT) recorded net inflows of $665.16 million on Monday, Oct. 19, according to the primary report from Cryptopolitan. That single-day intake exceeded the $526.6 million net total collected by all U.S. spot Bitcoin ETFs combined, indicating that other funds were net sellers on the day. Fidelity's FBTC lost $83.63 million and Grayscale's GBTC shed $54.93 million, a combined outflow of roughly $139 million.
IBIT's inflow was its biggest one-day gain since Oct. 7, 2025 and the largest of 2026. The fund now holds net assets of $66.37 billion and took in approximately 8,130 BTC on the day. Across all spot Bitcoin ETFs, total traded value reached $2.09 billion, net assets finished at $105.46 billion, and cumulative net inflows since the January 2024 launch stand at $57.40 billion. The group had lost around $229 million the prior week, with about $165 million of that from IBIT. Cryptopolitan had previously reported that Bitcoin ETFs turned negative for October after a $487 million outflow, with IBIT losing $207.7 million that day. The group's last larger inflow day was Sept. 22, at $714.75 million.
Bitcoin remained within a narrow band of roughly $82,000 to $83,000 as fears of further interest rate hikes weighed on risk assets. Min Jung, associate researcher at Presto Research, said it was unclear why IBIT was buying, suggesting a possible "catch-up trade" as other risk assets trade near all-time highs, and expected volatility to persist while Federal Reserve policy remains uncertain. Dominick John, an analyst at Zeus Research, said the flows indicate institutional demand is holding up, with ETF buying absorbing sellers at resistance. Market commentator Luke Martin noted the last IBIT inflow of comparable size preceded Bitcoin's strong run in August.
In ether and other altcoin products, outflows continued. Ether ETFs posted a fourth straight day of outflows totaling $103.28 million, with BlackRock's ETHA accounting for $95.40 million, and assets fell to $14.77 billion. Solana ETFs were down for an 11th consecutive day with net outflows of $6.72 million, leaving assets at $1.63 billion. Grayscale's ZCSH Zcash fund lost $10.45 million, while Bitwise's NRR Near ETF added $5.42 million. Separately, BlackRock filed on Monday for the iShares Bitcoin Managed Protection ETF (PBIT), an actively managed options fund based on IBIT that caps upside in exchange for some downside protection.
