Geeknewz exclusive data read of US spot crypto ETF flows for October 1–2, 2026, built from Farside Investors Bitcoin ETF Flow, Farside Ethereum ETF Flow, and same-day market context from CryptoSlate and NewsBTC. Numbers below are Farside's published session totals in millions of US dollars. No invented quotes or off-table estimates.
The headline on October 1 looked simple: US spot Bitcoin ETFs flipped back to net inflows after a redemption day. Dig one layer deeper and the day is almost entirely a BlackRock story sitting next to another day of Ethereum fund outflows. That split is the Geeknewz angle. Regulated brokerage demand did not move as one crypto blob.
Below is the issuer table from Farside, our own concentration math, the Bitcoin-versus-Ethereum gap, and a plain verdict on what one strong IBIT print can and cannot prove.
What Farside printed for Oct 1
Farside's Bitcoin table shows a category total of $102.7M net inflows on October 1. BlackRock's IBIT alone added $195.6M. Fidelity's FBTC lost $60.7M, Grayscale's GBTC lost $31.4M, and several smaller products also redeemed. Grayscale's lower-fee Bitcoin Mini Trust (listed as BTC on Farside) added $14.6M, and Morgan Stanley's MSBT added $7.0M.
| Fund (Farside) | Oct 1 flow ($M) | Fee (Farside) |
|---|---|---|
| IBIT (BlackRock) | +195.6 | 0.25% |
| FBTC (Fidelity) | -60.7 | 0.25% |
| GBTC (Grayscale) | -31.4 | 1.50% |
| BTC / Mini Trust | +14.6 | 0.15% |
| MSBT | +7.0 | 0.14% |
| BITB / ARKB / others (net) | -22.4 | mixed |
| US spot BTC total | +102.7 |
Our math on concentration: take IBIT out of the day and the rest of the Bitcoin complex sums to 102.7 − 195.6 = −$92.9M. Every dollar of the positive headline was IBIT covering other funds' redemptions, then some. Positive prints that day were IBIT ($195.6M), Mini Trust ($14.6M), and MSBT ($7.0M), or $217.2M of gross creations. IBIT was 195.6 ÷ 217.2 ≈ 90% of that gross. Category net was positive; breadth was not.
The ETH side of the same session
Farside's Ethereum table shows −$55.4M net for October 1. That is not a crash-sized print by itself, but it lands on the same calendar day Bitcoin funds took $102.7M. The relative gap is 102.7 − (−55.4) = $158.1M of opposite direction between the two largest US spot crypto ETF stacks.
Day-over-day context on Bitcoin: September 30 was −$148.7M on Farside. October 1's +$102.7M is a $251.4M swing from the prior session. CryptoSlate tied the overnight reclaim of about $86,000 to that flow flip plus short-cover pressure ahead of the US jobs print. Useful color, not a substitute for the fund tape.
Early October 2 on Farside (still incomplete for some columns when we checked) already showed Bitcoin products at about +$31.7M with IBIT still blank, while Ethereum sat at about −$17.3M. Treat that as a live board, not a closed session.
Issuer fees on Farside also help explain some of the shuffle. GBTC still lists at 1.50%, while Mini Trust sits at 0.15% and MSBT at 0.14%. When money leaves a high-fee wrapper and lands in IBIT or a mini trust, the category can look quieter than the desks feel. October 1 was not only fee arbitrage, though. FBTC at 0.25% redeemed $60.7M while IBIT at the same headline fee took in $195.6M, so ticker preference and liquidity mattered more than a pure fee race that day.
Geeknewz verdict
Geeknewz's view: read October 1 as a BlackRock absorption day, not a broad institutional stampede back into every Bitcoin wrapper. A single $195.6M IBIT print can turn the category green while Fidelity, Grayscale, and others still shrink. If the next few sessions broaden across issuers, the demand signal gets stronger. If IBIT keeps doing all the work, the headline inflows overstate how many desks are actually adding risk.
On Ether, one −$55.4M day is noise until it stacks. Watch whether ETH products keep redeeming while BTC stays positive. That is the cleaner tell than any one-day tweet about "crypto inflows." ETF flows still miss OTC desks, corporate treasuries, and futures. They do show where brokerage-accessible US money moved on the day, and on October 1 that money preferred Bitcoin wrappers over Ethereum ones, with BlackRock doing the heavy lifting.
