BlackRock's iShares Bitcoin Trust (IBIT) drew $665.2 million in a reversal of Bitcoin (BTC) exchange-traded fund flows, according to a COINOTAG report published on October 20, 2026. Daily flow figures for U.S.-listed Bitcoin ETFs are widely tracked because they offer a running measure of investor demand for Bitcoin exposure through regulated, exchange-listed vehicles.

COINOTAG Update 07:14 UTC: On-chain context adds a floor to the picture, with these readings landing later than Monday's $83,155 peak on Binance.

IBIT is the ticker for the iShares Bitcoin Trust, a spot Bitcoin ETF issued by BlackRock, the world's largest asset manager. The fund began trading in January 2024, after the U.S. Securities and Exchange Commission approved the first group of spot Bitcoin exchange-traded funds in the United States. Since its launch, IBIT has grown to become the largest spot Bitcoin ETF by assets under management — a scale that has made its daily flows a regular reference point in coverage of the broader Bitcoin ETF category.

The $665.2 million figure refers to flows into the fund as tracked by COINOTAG, which characterized the movement as a reversal in Bitcoin ETF flows. In ETF coverage, a reversal denotes a shift in the direction of net flows rather than a specific price level. The accompanying on-chain readings, published after the $83,155 price peak on Binance earlier in the week, were presented as additional context supporting a floor beneath the market, according to the report. Subsequent daily flow updates and on-chain readings from the same source are the data points to watch in determining whether the pattern described in the report continued.
