Bitcoin ETF Inflow Streak Snaps as BTC Slides Below $78K After Hitting 3-Month High
U.S. spot Bitcoin ETFs booked their first outflow in nine trading sessions on Friday, coinciding with Bitcoin's pullback from a three-month high above $81,000. Here's what the reversal means for the market heading into the weekend.
A Nine-Day Winning Streak Comes to an End
U.S.-listed spot Bitcoin ETFs closed out the trading week on a sour note, recording roughly $202 million in net outflows on Friday, August 28. The move snapped a nine-session inflow streak that had pulled in more than $3 billion and pushed total fund assets past the $100 billion mark for the first time earlier in the week. ARK 21Shares' Bitcoin ETF led the redemptions, according to data from SoSoValue, while total net assets held by the funds slipped back to roughly $97.6 billion.
Despite Friday's reversal, the picture for August as a whole remains firmly positive. Net inflows for the month stayed above $3 billion, making it the strongest month for U.S. spot Bitcoin ETFs since October 2025, and cumulative inflows since the funds launched in January 2024 remain in the low-to-mid $50 billion range. Analysts largely characterized the single-day outflow as profit-taking and portfolio rebalancing after a rapid run-up, rather than a sign that institutional appetite for Bitcoin exposure is fading.
Bitcoin Pulls Back From a Three-Month High
The ETF reversal tracked closely with Bitcoin's own price action. After climbing from the low-$60,000s in mid-August, BTC touched an intraday high above $81,000 on August 28 before sellers stepped in, pulling the price down roughly 3% to close the day near $77,400–$77,800. Weekend trading on August 29 has been comparatively subdued, with Bitcoin holding in the mid-$77,000s.
That August rally had been fueled by a mix of factors: renewed ETF demand, a wave of short-position liquidations, and a U.S. Treasury move to expand longer-dated bond buybacks, which markets read as a liquidity-friendly signal. With that momentum now cooling, the broader cryptocurrency market followed Bitcoin lower. Total crypto market capitalization fell roughly 2.9% over the past 24 hours to about $2.72 trillion, even as trading volume stayed elevated near $97.6 billion. Bitcoin's dominance of the overall market held steady at around 57.4%, with Ethereum accounting for roughly 10.9%.
What Investors Are Watching Next
Market participants are treating Friday's ETF outflow as a single data point rather than a trend reversal. A one-day pause after nine consecutive inflow sessions is common following a fast rally, and the funds continue to hold well over a million bitcoin in aggregate. Still, with only one U.S. trading session left in August, whether inflows resume — or Bitcoin's pullback deepens — will help set the tone for crypto markets heading into September.
For now, the combination of a cooling ETF bid and Bitcoin's retreat from three-month highs suggests the market is digesting one of its strongest rallies of the year, rather than reversing course entirely.
