U.S. spot Bitcoin ETFs recorded approximately $241 million in net inflows during the trading week from September 28 through October 2, extending their positive run to three consecutive weeks. According to SoSoValue’s U.S. crypto spot ETF dashboard, the latest total represented a sharp slowdown from the roughly $2.39 billion attracted during the preceding five sessions. Bitcoin ETF demand remained net positive for the week despite a substantial midweek redemption day and a roughly 90% decline from the prior week’s inflow total.
Farside Investors’ daily data reconciles the latest week to about $241.1 million: $31 million on September 28, $66.2 million on September 29, a $148.7 million outflow on September 30, followed by $102.7 million and $189.9 million of inflows on October 1 and 2. The weekly result therefore reflects volatile creation and redemption activity rather than five consistently positive trading sessions. The September 30 reversal came after Bitcoin ETFs had accumulated roughly $3.08 billion during a nine-session inflow streak.
BlackRock Offsets Outflows Elsewhere
BlackRock’s IBIT accounted for roughly $450 million of weekly net inflows, exceeding the entire category’s $241 million net result. ARK 21Shares’ ARKB added approximately $25.5 million, while Fidelity’s FBTC recorded about $168 million in net redemptions. The distribution shows that the positive weekly headline was concentrated rather than shared evenly across Bitcoin ETF issuers.
The slowdown looks especially pronounced against the preceding week. Bitcoin ETFs attracted approximately $999 million on September 21, $714.7 million on September 22 and $346.9 million the following day before finishing the week with smaller positive sessions. The latest $241 million week extends the positive sequence, but at a substantially lower rate than the late-September surge, which included a $999 million single-day Bitcoin ETF inflow.
Ether ETFs moved in the opposite direction. ETF flow data shows approximately $138 million of net outflows between September 28 and October 2, including sizable withdrawals during the final three trading sessions. The withdrawals erased the week’s small opening inflow and pushed cumulative Ether ETF net inflows down from their recent peak. The result marked the second negative week in the past three after a strong positive stretch ending September 25.
Bitcoin and Ether ETF Flows Diverge
The split between Bitcoin and Ether does not establish a broad institutional preference for one asset over the other. ETF flows can reflect portfolio rebalancing, arbitrage, adviser allocations, retail orders and other creation or redemption activity. What the data establishes is narrower: Bitcoin products received net new creations during the week while Ether products experienced net redemptions.
That contrast is also part of a highly variable September pattern. Earlier in the month, Bitcoin ETFs lost roughly $463 million across four consecutive sessions before flows reversed strongly later in September. Short streaks of inflows or outflows therefore provide a snapshot of fund activity rather than evidence of a durable allocation trend.
Smaller crypto ETF categories recorded comparatively modest activity. SoSoValue data put XRP spot ETFs at approximately $4.74 million in net inflows and Solana products at about $2.43 million during the tracking period. Those totals were much smaller than the Bitcoin and Ether flows and should remain tied to SoSoValue’s specific methodology and reporting coverage.
The week ultimately preserves Bitcoin’s positive streak while showing considerably weaker momentum than the previous period. Three consecutive positive Bitcoin ETF weeks demonstrate sustained net creations through the regulated fund wrappers, but neither the flows nor the contrast with Ether reveal the identity of the underlying investors or guarantee that the pattern will continue. The September 30 redemption, followed immediately by two positive sessions, shows how much day-to-day volatility can sit underneath a positive weekly total.
