BlackRock's IBIT Draws $665.2 Million in Bitcoin (BTC) ETF Flow Reversal

IBIT Carries the $665.2 Million Turn

US spot Bitcoin (BTC) ETFs swung back to net inflows on Monday, taking in $526.7 million in their largest single-day intake since Sept. 22, when the cohort pulled $714.7 million. The Bitcoin (BTC) price did not keep up: the coin's Binance price history shows a Monday peak of $83,155 and a close of $81,938, about 0.22% lower on the day, and it now trades near $81,800, barely changed since. BlackRock's iShares Bitcoin Trust (IBIT) carried the session on its own, absorbing $665.2 million, a figure larger than the whole group's net total. Two rivals worked against it: Fidelity's Wise Origin Bitcoin Fund (FBTC) shed $83.6 million and Grayscale Bitcoin Trust (GBTC) lost $54.9 million, while every other fund sat flat. Daily flow disclosures tracked by Farside Investors, which compile the issuers' creation and redemption filings, carry the breakdown. Because these products operate through spot trading, buying the coin directly rather than through futures, a creation day of this size usually reaches the market as fresh orders, and the gap between $526.7 million in and a flat close is what this session leaves to explain.

October Ledger Still Underwater

The backdrop makes Monday's figure stand out. Weekly Bitcoin ETF flows had turned negative in each of the previous two weeks: roughly $229 million left last week on top of $681 million the week before, and Oct. 7 alone saw $483.9 million walk out the door, the heaviest daily withdrawal since June. Friday's session on Oct. 16 added another $82.4 million in net outflows, the exact hole Monday's intake filled and exceeded. Even so, the month is not repaired. After Monday's session the cohort remains about $88 million negative for October as a whole, so one strong day has offset only a fraction of the pressure. The mechanics matter when reading the tape: these funds issue shares against coins held in custody, and our primer on how spot Bitcoin ETFs work explains why a creation-heavy print does not always hit the order book one-for-one, since execution, hedging by authorized participants and liquidity all sit between the flow figure and the market.

Resistance Cluster at $84,404

Our own level map frames where Monday leaves the coin. Spot sits at $81,846 at the time of writing, down 1.07% across 24 hours but just 0.1% below its level when the flow figures landed. Below, the strongest support reads $81,333 and scores 91 out of 100, a shelf that leans on the 0.236 Fibonacci retracement alongside its other references. Above, $84,404 carries an 89/100 as the heaviest resistance. Momentum is tepid in between: the relative strength index prints 48.9, the MACD signal is bearish, and the broader trend still grades as an uptrend. Positioning is calm, with perp funding at 0.0056% and open interest near $15.9 billion. The full ladder of levels sits in our Bitcoin technical analysis. Either a close through $84,404 or a break of $81,333 would force a rewrite of the near-term picture.

Altcoin ETFs Keep Leaking

The split ran through the rest of the board too. Ether funds kept their exit streak, and the altcoin side of the market offers an even sharper contrast: Solana products shed $6.7 million in total, with Bitwise's BSOL at $4.9 million and Fidelity's FSOL at $1.8 million, while Grayscale's Zcash vehicle lost $10.4 million, its second heavy day after $14.8 million left on Oct. 15. The Hyperliquid ETF recorded no net movement at all. Add the markets together and Bitcoin (BTC) did all the lifting: combined net inflows across the five tracked digital-asset ETF markets came to $406.3 million, meaning Bitcoin's intake covered every other asset's withdrawals and then some. Solana funds have logged net outflows on most October trading days, and the Zcash product has leaked repeatedly through the month. None of these vehicles showed anything resembling the demand that hit Bitcoin's funds on Monday.

Ether's Fourth Straight Day Out

Ether's ledger is the cleanest read on the divergence. Spot Ether ETFs have now posted net outflows four trading days in a row, and Monday's exit was broad rather than concentrated in one product: ETHA gave up $95.4 million, Fidelity's FETH $5.96 million and Grayscale's ETHE $1.92 million. The weekly record is no kinder. Ether funds shed about $320 million last week, a third consecutive week of net withdrawals, after daily losses of $160.9 million on Oct. 7 and $129.5 million on Oct. 14, with only a one-day inflow of $24.8 million on Oct. 13 interrupting the run. Set the two markets side by side as the session closes: Bitcoin's funds took in $526.7 million while the coin itself finished Monday at $81,938 and now sits near $81,800, effectively flat, whereas Ether's outflow streak continues with nothing comparable coming in. The two series, money and price, still do not point the same way on the Bitcoin (BTC) side, and whether Monday's demand carries into a second session is the next data point for both.
