BlackRock's IBIT and ETHA absorb nearly all new crypto ETF money

US spot Bitcoin and Ethereum ETFs pulled in a combined $892.7 million over the two trading days of August 26 and 27, according to Farside Investors flow data. The headline number hides where the money went.

BlackRock's IBIT took in $478.4 million of that on its own, more than the entire Bitcoin ETF category combined. Grayscale's GBTC gave back $77.6 million over the same two days, and Fidelity's FBTC, normally the second-largest Bitcoin fund by inflows, flipped to a net outflow of $58 million after a sharp $83.6 million withdrawal on August 27 alone. Smaller funds from Bitwise, Ark, and VanEck added modest inflows, and Bitcoin's spot ETFs closed the two days at $474.5 million net, a category total smaller than IBIT's inflow by itself.

Ethereum ETFs told a similar story on a smaller scale. BlackRock's ETHA pulled in $245.9 million over the two days, nearly 59% of the category's $418.2 million total. Fidelity's FETH added $88.2 million, and the rest of the field, funds from Bitwise, 21Shares, VanEck, Invesco, and Franklin, split what remained.

• IBIT (BlackRock), Aug 26-27: +$478.4M combined
• GBTC (Grayscale), Aug 26-27: -$77.6M combined
• FBTC (Fidelity), Aug 26-27: -$58.0M net, despite a positive first day
• Grayscale's low-fee BTC fund, Aug 26-27: +$58.5M combined
• All Bitcoin spot ETFs, Aug 26-27: +$474.5M combined
• ETHA (BlackRock), Aug 26-27: +$245.9M, 59% of the Ethereum ETF total
• Grayscale's low-fee ETH fund, Aug 26-27: +$49M combined
• All Ethereum spot ETFs, Aug 26-27: +$418.2M combined

The inflows land as Bitcoin trades near $79,700, up 1.2% over 24 hours, after a rebound capped by a cluster of moving averages under $80,000 earlier this week. The two days extend a run Intokened covered when it reached six days and $2.26 billion, a streak other trackers now put at nine consecutive days.

None of this means institutional interest in Bitcoin and Ethereum ETFs is fading. It means that interest is concentrating in one place. IBIT charges a 0.25% fee against GBTC's 1.50%, and every week that gap sits there is another week for money managers to notice it. Fidelity's single-day reversal is the more interesting signal: even a fund that usually ranks second is starting to see the kind of exit that used to be reserved for Grayscale's legacy product alone.

Grayscale's own cheaper spinoffs tell the same story from a different angle. Its low-fee BTC and ETH funds, launched specifically to compete with IBIT and ETHA on price, took in $58.5 million and $49 million respectively over the same two days, even as the original GBTC bled. Grayscale isn't losing the ETF race outright; it's losing the high-fee version of it, and its own cut-price product is catching some of the money leaving GBTC's door.
