BlackRock Bitcoin ETF Pulls In $665 Million While Rivals Lose Money

TL;DR: BlackRock’s IBIT recorded roughly $665 million in net inflows on October 19, even as several other US spot Bitcoin ETFs saw investors take money out.

A strong day for Bitcoin ETFs wasn’t quite as broad-based as the headline number suggests. BlackRock’s iShares Bitcoin Trust took in approximately $665.16 million on Monday, according to SoSoValue’s fund-flow figures, while the US spot Bitcoin ETF group recorded a combined inflow of about $526.6 million.

That difference is the story. Money going into IBIT more than offset withdrawals from competing funds. Fidelity’s FBTC registered roughly $83.6 million in outflows, while Grayscale’s GBTC shed about $54.9 million.

Rather than a uniform surge of demand for every Bitcoin product, Monday’s numbers point to a preference for the market’s biggest vehicle. IBIT has become the default choice for many investors seeking exchange-traded Bitcoin exposure, although a single day’s figures cannot establish why individual institutions moved money.

The reversal also follows a Friday session in which the group recorded net withdrawals. It underscores how quickly flows can shift around market volatility and broader risk sentiment.

Flows are useful evidence of ETF subscriptions and redemptions, but they shouldn’t be read as a direct measure of new cash buying Bitcoin at a particular hour. Fund mechanics and market-making activity complicate that picture.

The next question is whether demand spreads to other products or whether IBIT continues to absorb most of the market’s incremental interest.
