BlackRock's IBIT draws $450 million in a week when all US bitcoin ETFs net $241 million
BlackRock's IBIT took in $450 million last week while all US spot bitcoin ETFs together netted $241 million, about 90% less than the week before. That keeps a three-week inflow streak alive on one fund's buyers heading into October.
The Investor · Invest desk
What happened
- Fidelity's FBTC lost $167.94 million, Grayscale's GBTC $54.58 million and Bitwise's BITB $38.65 million in net outflows over the week.
- A $148.69 million outflow on Wednesday ended a nine-session run of inflows before buyers added $102.67 million Thursday and $189.84 million Friday.
- Ether ETFs swung to about $138 million of net outflows after taking in $690 million the week before.
- Bitcoin traded near $86,200, up about 3.7% over seven days, according to CoinGecko.
Why it matters
- Who's exposed exposure One week of flat IBIT flows would end the streak if outflows at FBTC, GBTC and BITB continue at last week's pace.
- What it costs cost Fidelity bears the cost of the split: its bitcoin and ether funds lost a combined $242 million in one week, about the bitcoin category's entire net intake.
- What doesn't add up contradiction Bitcoin.com credits ETF strength with an institutional cushion under bitcoin's price, but SoSoValue's year-to-date total implies that cushion was built in September after eight months of net outflows.

Two funds account for 85% of Thursday's $317 million bitcoin and ether ETF outflowConfirmed2 publishers
Take IBIT out and every other US spot bitcoin ETF together lost $209.10 million in the week [19]. BlackRock's fund took in about 1.87 times the category's net [27]. FBTC, GBTC and BITB shed $261.17 million between them [20], so the remaining funds took in about $52 million net [21].
The 90% figure depends on which week you measure against. Last week's intake was roughly a tenth of the $2.39 billion from the five sessions before [2]. Against the streak's opening week [8], it was about 39 times larger [23]. About 91% of the three weeks' money came in the middle week [24].
September brought in more than the year has. SoSoValue puts year-to-date net inflows at about $1.2 billion and the cumulative total at $57.8 billion, according to Cointelegraph [14][7]. Bitcoin.com counts $2.65 billion for September alone [12], about $1.45 billion more than the year's running total [18]. The two publishers' weekly figures agree, at $241.08 million and $241.1 million [1][7]. For January through August to have been positive, the first days of October would have had to lose more than $1.45 billion. The week had one outflow day, and it was about a tenth that size [9]. The eight months before September were therefore net outflows [18].
The week supports more than one reading. In one, the middle week of the streak was a spike, a few hundred million a week is the normal pace, and IBIT is taking share from older funds. In another, weakness elsewhere reaches bitcoin funds next: the ether reversal [4] came in the same week Zcash funds had their first weekly outflow on record, about $94 million [5]. In a third, price and flows separate. Bitcoin rose over a week of slower ETF buying [15], and according to Bitcoin.com, September payrolls of 29,000, below expectations, eased fears of more Federal Reserve tightening [17].
I think the evidence supports cooling plus concentration, with no reversal yet. The streak held, and Friday was the week's largest inflow day [9]. The counter-thesis is that the category outside IBIT is already reversing, with a few large IBIT buyers propping up the total [19]. The weekly data does not show whether IBIT's money came from new buyers or from holders switching out of FBTC and GBTC [10][11]. The view is wrong if IBIT itself posts an outflow week [10], or if bitcoin funds follow ether into outflows in October [4].
New money outside bitcoin and ether went mostly to the newest product. Bitwise's NEAR fund took $58.35 million in its first week [13], more than five times the $10.48 million that went into Solana, XRP and HYPE ETFs combined [26]. That more than covered Bitwise's BITB outflow, leaving the issuer $19.70 million ahead across the two funds [25]. ETF Store president Nate Geraci called the SEC's approval of listings for the first 3x leveraged bitcoin and ether ETFs a "wild turn of events" [16].
What to watch
- Bitcoin.com names October flows staying positive as the key test; a negative first full week would end the streak at three.
- Early flows into the newly approved 3x leveraged bitcoin and ether ETFs, and whether they draw money from spot funds.
- NEAR's second week, after its daily inflows fell from $35.99 million on debut day to $241,620 on Friday.
