The Block2 min read6 sources

Why are Bitcoin ETF inflows up seven days in a row?

US spot Bitcoin ETFs (BTC) logged $134.5M in net inflows on Friday — a seventh straight session totaling $2.98B — even as Bitcoin fell to $83,100 Monday on a broad risk-asset selloff.

What happened

US spot Bitcoin ETFs (BTC) logged $134.5M in net inflows on Friday — a seventh straight session totaling $2.98B — even as Bitcoin fell to $83,100 Monday on a broad risk-asset selloff. The buying streak ran September 17 through 25, with the peak on September 21 when the funds absorbed $999M, the single largest daily haul of 2026. BlackRock's IBIT led with $1.2B for the week, Fidelity's FBTC added $701.7M, and Ark's ARKB contributed $294.7M. The run absorbed the $351.6M Bitget exchange hack on September 24 without institutional retreat, and flipped 2026 year-to-date flows positive for the first time since May.

Why it matters

US spot Bitcoin ETFs absorbing a $351.6M exchange hack without a single day of outflows shows that institutional demand has grown more resilient than in earlier cycles. September is now on track to close as the strongest ETF-inflow month of 2026, with roughly $4.8B in net new capital, exceeding August's prior record of $3.52B. That resilience, combined with Bitcoin holding near $83,000 during a risk-off Monday driven by rising Treasury yields and Iran tensions, signals the asset class is increasingly weathering external shocks as Q4 approaches.
