BlackRock's IBIT Drew $292M to Lead US Bitcoin (BTC) ETFs' Third Weekly Inflow

IBIT Carries a Third Week of Inflows

US spot Bitcoin (BTC) ETF market closed a third consecutive week of net inflows, taking in $82.93 million for the five trading days from September 28 through October 2. BlackRock's iShares Bitcoin Trust (IBIT) did nearly all the lifting, absorbing $292 million, a figure that more than covers the redemptions posted by every other fund in the lineup combined. Daily flow data from SoSoValue, the analytics platform that aggregates the sector's creations and redemptions, confirms the streak: the last three weekly tallies are all positive, and each has leaned on the same flagship product. The math makes the concentration plain. Strip IBIT out of the aggregate and the remaining funds ran a net deficit for the week, so the headline inflow exists because a single issuer's vehicle out-earned the sector's exits. Grayscale's Bitcoin Mini Trust contributed $24.9 million and the ARK 21Shares Bitcoin ETF (ARKB) added $25.5 million, lifting ARKB's cumulative net intake to roughly $1.4 billion. IBIT itself now holds a lifetime record of $65.73 billion in net creations, the deepest pool of institutional capital in the entire complex. The flows arrived as the market itself firmed: Bitcoin (BTC) price printed $86,326 around 08:25 UTC on Monday, a 1.5% gain over 24 hours, so the institutional bid is landing on an appreciating tape rather than defending a falling one. For an asset class that spent years dependent on offshore vehicles and opaque custody, three straight weeks of ETF demand marks a settled channel, and nothing in the weekly data suggests it is breaking.

The outflow column shows where the money moved from. Fidelity's Wise Origin Bitcoin (BTC) Fund (FBTC) posted the largest exit of any major fund at $167.9 million for the week, and $125.58 million of that left in a single session on September 30, a one-day withdrawal of the size usually associated with whale accounts repositioning. Analysts read the timing as quarter-end portfolio rebalancing plus profit-taking after a strong stretch, and the same logic runs through the legacy share class: Grayscale's Bitcoin Trust (GBTC) lost another $54.6 million, even though the same issuer's Mini Trust took in $24.9 million. One issuer's product family split in two directions during the same week, the cleanest evidence that this is rotation between wrappers, not a retreat from the asset. September's full tally sharpens the point: US spot Bitcoin ETFs absorbed $2.65 billion for the month, the second-highest monthly figure on record behind August, so the institutional bid is broad in aggregate even when it is narrow in any given week. Distribution now matters more than direction. Concentration into IBIT means the ETF market's health tracks one fund's behavior, and the accumulation discipline behind the strategic bitcoin reserve model is playing out inside a single product. Allocators are being selective about vehicle, fee and liquidity rather than applying a uniform HODL stance to their exposure, and that choice shows up weekly in the flows across the wider Bitcoin ecosystem.

$87,331 Resistance in Focus

COINOTAG's proprietary 42-indicator composite S/R scoring engine rates the $87,331 resistance at 90/100 on a confluence of the swing high, R1 and the Donchian upper band, with the strongest support at $85,233 scoring 84/100 from the Ichimoku Tenkan, a low-volume node and a resistance-to-support flip. Spot trades at $86,326, up 1.5% over 24 hours, after the Uptober rally cooled from Sunday's push. RSI prints 67.79, the MACD signal is bearish and the trend stays up. Funding of 0.0049%, open interest of $16.61 billion and a 1.07 long/short account ratio keep positioning constructive, and the Fear and Greed Index reads 70, in Greed. A break above $87,331 opens $95,445 next; rejection and a loss of $85,233 would invalidate the bullish read. The full Bitcoin technical analysis tracks every level, and our earlier work on the largest liquidation cluster at $90K frames the squeeze risk overhead, with three straight weekly ETF inflows after September's $2.65 billion backing the bid.
