Timing, as they say, is everything. In the days before Federal Reserve Chair Kevin Warsh delivered a hawkish policy speech on August 28, 2026, institutional investors were loading up on crypto ETFs at a notable pace. Then Warsh spoke, and the trade turned ugly fast.

Eight sessions, $2.8 billion, and then the floor fell out

The inflow streak wasn’t a one-day phenomenon. U.S. spot Bitcoin ETFs had logged eight consecutive sessions of net positive flows before Warsh took the podium, accumulating $2.8 billion in total over that run.

That sustained buying pushed total Bitcoin ETF assets under management to $98.56 billion, putting the funds within $1.44 billion of a symbolic $100 billion milestone.

BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) were the primary vehicles drawing institutional capital. Authorized participants including Jane Street and Citadel facilitated the mechanics of those flows, handling the creation and redemption processes that keep ETF prices tethered to underlying Bitcoin values.
