What happened: the streak snapped, but only one fund created baskets

US spot Bitcoin ETFs recorded a net inflow of about $32.1 million on July 29, 2026, ending a four-day outflow streak that had bled roughly $526 million from the category, per KuCoin's flash desk and Bloomingbit. The turn landed the same afternoon the Federal Reserve left rates unchanged — exactly the post-decision reset we flagged a day earlier in Bitcoin ETFs bleed a 4th day into the Fed.

But the headline number hides the mechanics. The entire net inflow was one issuer:

Strip out IBIT and the group was still ~$57.7 million in the red. BlackRock's +$89.8M didn't just carry the tape — it out-created the rest of the complex's redemptions by enough to flip the sign, per fund-level figures compiled by Blockchain.News. Category NAV sat near $77.46B, about 6.08% of Bitcoin's market cap, with cumulative net inflows of ~$51.36B.

The macro trigger: a hold, but a hawkish one

The Fed held the federal funds rate at 3.50%-3.75% on July 29 in a 9-3 vote, with regional presidents Beth Hammack, Neel Kashkari and Lorie Logan dissenting in favor of a 25bps hike — the first time since 2016 that three officials dissented on the hawkish side, per cryptonews.com and the Bitcoin Foundation's Fed recap. Chair Kevin Warsh voted with the majority to hold.

Bitcoin jumped from about $63,700 to nearly $64,700 on the print before fading back toward $64,000 as desks parsed the hawkish dissent, per CoinDesk's Fed-day live coverage. Ether was the laggard, drifting near $1,900 with little conviction as its funds gave back some of a three-week inflow run.

This is the ETF-plumbing point that matters: a `hold` removed the binary tail risk that had pushed authorized participants to flatten inventory into the meeting. With the event cleared, the desk most willing to re-create baskets — BlackRock's — did so first and largest, while Fidelity's and ARK's APs stayed on the sidelines. A single day's creation decision at one issuer, not a broad institutional re-risking, is what turned the category print green.

What it means for investors

A +$32.1M print is not a green light — it's an IBIT print. When one fund supplies more than 100% of a day's net creations, the aggregate "Bitcoin ETF inflow" headline tells you what BlackRock's book did, not what the market did. That's the same concentration dynamic that made IBIT's inflow streak snapping a category-wide event on the way down — and it cuts both ways. Watch the breadth of creations across FBTC and ARKB, not the net total, before reading a real re-risking.

The reversal confirms the positioning thesis, not a trend change. We argued yesterday that four red sessions into a coin-flip Fed print were inventory management, and that the tell would be creations resuming once the uncertainty cleared. They did — but narrowly. One clean day off a macro catalyst is consistent with APs unwinding a pre-FOMC hedge; two or three days of *broad* inflows would be the signal that conviction, not plumbing, is back.

Mind the NAV-versus-price gap on days like this. When a decision hits mid-session and price whipsaws $1,000 in an hour, an ETF's last trade can drift from its intraday indicative value until creations arbitrage the spread. The premium/discount mechanics that keep these funds tethered to spot get noisiest exactly when a Fed print is moving the tape — so on July 29 the flow number is a lagging read on yesterday's book, while the spread was the live signal.

Bottom line: the streak snapped, but the reversal is one desk deep. Until FBTC and ARKB stop redeeming, treat the green headline as BlackRock rebuilding inventory after a cleared macro event — not as institutions collectively stepping back in.
