BTC ETF AUM Crosses $100B, 7-Day Inflow $2.56B
BTC ETF AUM crossed the $100B mark
BTC ETF AUM crossed $100 billion for the first time on Wednesday. The combined holdings of the US spot funds closed at $100.9B, up from $98.6B the day before, after another $242.2M of net inflows. The number matters less than the path: inflows have now been positive for nine straight sessions since August 17, adding roughly $3.0B in that window alone.
The flow picture behind the milestone
Wednesday's $242.2M intake pushed the seven-day total to $2.56B. Cumulative net inflows now stand at $54.9B. Fund AUM has grown from $84.3B on August 19 to $100.9B in six trading days, a $16.6B jump driven mostly by fresh money rather than price appreciation.
Spot price is not following the flows
BTC trades near $79.7K at the time of writing, up about 1.4% in 24 hours but still below the $81.5K 24-hour high. Binance and OKX both show the same picture: price holding in the $79K-80K band, 24h range roughly $78.5K to $81.5K on both venues. Institutions keep buying, yet the spot price keeps getting sold into. Someone on the other side is happy to hand over coins at these levels, which is typical when ETF buying meets profit-taking from earlier entries.
Derivatives stay calm, funding near zero
Open interest across BTC futures sits at $45.3B, up just 1% in 24 hours. Funding rates are effectively neutral: Binance at 0.01% and OKX at 0.0086% per 8 hours, both far from the levels that mark a crowded long. Liquidations tell a similar story, $457.7M wiped market-wide in 24 hours with shorts paying 63% of it, but BTC's own $149.6M slice is small relative to its open interest. Leverage is not chasing this rally.
What it means for traders
The ETF milestone confirms institutional demand is real and persistent around $79K-81K, a zone that has now absorbed over $3B of net ETF buying in nine sessions without breaking lower. But a sustainable breakout needs derivatives participation, and funding near zero shows leveraged traders have not joined in yet. Watch two things: whether ETF inflows keep running at this pace, and whether funding climbs above 0.03% on a sustained basis, a sign longs are finally willing to pay up. Until then, the $79K support stays the line in the sand, with the $81.5K high as the immediate ceiling.
