U.S. spot Bitcoin ETFs took in $241.1 million in net inflows last week, the third straight week of positive flows, according to fund data. BlackRock's iShares Bitcoin Trust did most of the heavy lifting, pulling in more than $450 million — the largest weekly haul among the listed funds.
The buying wasn't perfectly even. Money came in every trading day except Wednesday, when roughly $149 million left the funds. Fidelity- and Morgan Stanley-managed products also saw notable trading activity and inflows during the week.
What's driving the bid
The macro backdrop has shifted. Bitcoin began rallying in August after the U.S. Treasury Department said it would more than double the size of its government debt repurchases — a liquidity move that tends to help risk assets. The dollar weakened in August, then rose nearly 6% over a 30-day stretch in September, adding another variable for traders to weigh.
On-chain analytics firm CryptoQuant noted in September that Bitcoin had crossed back above its 365-day moving average, a signal that has historically preceded sustained rallies. By the numbers, Bitcoin's third quarter was its best three-month stretch since 2024.
A bear market that won't quit
Context matters here. Bitcoin spent most of 2026 in a bear market, and it remains well off its all-time high of $126,080 set last October. That peak came just before a massive liquidation event knocked prices down, and the market has been clawing back since.
The current price sits around $85,605, up nearly 7% over the past 30 days. That's a recovery, not a victory lap. The gap between here and the October high is still wide enough that anyone who bought the top is deep underwater.
Uptober hopes
October has historically been a strong month for Bitcoin — traders call it 'Uptober' — and the ETF flow data suggests some investors are positioning for exactly that. The pattern of inflows, pause on Wednesday, then resumption, looks more like accumulation than a momentum chase.
Whether that holds depends on two things: the Treasury's debt repurchase program continuing to inject liquidity, and Bitcoin holding above that 365-day moving average. CryptoQuant's September note flagged the crossover as the start of a bull market, and so far the price action hasn't contradicted it.
But the funds are still a small slice of the market. BlackRock's $450 million week is real money, yet it's a fraction of what would be needed to retake the old high. The next few weeks will show whether this is a durable turn or another false start in a year that's mostly been red.
