BTC ETFs Draw $730.9M: Biggest Day Since January 14
Bitcoin ETFs post their strongest day since mid-January
Spot Bitcoin ETFs took in $730.9M on Wednesday, September 3, the largest single-session net inflow since January 14. The previous best day between February and August was April 17 at $663.9M, so the September 3 print did not just edge past the recent range; it cleared it by roughly ten percent. One session erased the damage from a stretch of choppy weeks, and the flow landed right as spot BTC was turning up from its $76,200 low.
AUM rebounds from $97B back above $103B
Total assets across the US spot Bitcoin ETF complex moved from $97.22B to $103.34B in a single reporting day. That jump bundles two forces: the $730.9M of new money plus mark-to-market gains, since BTC itself climbed through the session. The seven-day net is back to a positive $1.08B after a negative stretch that bottomed at a $236.5M outflow on September 1. For context, the complex sat near $169B at its October 2025 peak, so the current level still has ground to recover, but the direction has clearly turned.
Fund flows and the short squeeze fed each other
Derivatives data shows the move was accompanied by one of the heaviest short squeezes of the year: 24-hour liquidations reached roughly $619M and about 89 percent of that was short positions, with Hyperliquid reporting over 98 percent short-side liquidations at one point. BTC is now trading near $80,950 on Binance and OKX, up about 4.2 percent on the day, after touching a 24-hour low near $77,400. Institutional buyers were adding exposure during the early stage of that rebound rather than chasing the top, which is a different signal from the panic-buying pattern seen at local highs.
What the inflow pattern says next
Flows of this size rarely arrive in isolation. When ETF subscriptions line up with forced short covering, the two tend to reinforce each other in the following sessions, and the $103B AUM level becomes a reference point traders watch for support on any pullback. The main risk is the flip side: if the next US session prints a big outflow, the same leverage that amplified the squeeze can amplify the unwind, because open interest has been rebuilding alongside price. Watch the next two daily flow prints and whether funding rates start charging longs; a sustained inflow run above $300M per day would be the stronger confirmation, while a single-day reversal back to outflows would cool the momentum fast.
