Bitcoin spot ETFs pull in $723M as BTC tops $80,000

Bitcoin spot ETFs logged $723.1 million in net inflows on Sept. 3 after Bitcoin pushed through $80,000, according to Santiment Intelligence. The firm said it was the biggest single-day intake since January. Santiment noted that outsized inflows often follow sharp price moves, a sign that traders may be chasing momentum after gains are already in place. That dynamic can raise the risk of subsequent redemptions if the market pulls back. Flow data spanning January 2024 through mid-2026 shows pronounced two-way activity across cycles. Early 2024 saw frequent swings, including several inflow days above $500 million. Activity picked up again from October 2024 into early 2025, when multiple sessions ranged from roughly $800 million to $1 billion and the largest visible inflow neared $1.35 billion. Over the same stretch, outflows also climbed to about $700 million to $1 billion, underscoring large institutional trades moving in both directions. Santiment also pointed to June 26, when ETFs posted a major outflow near a market low, linking that session to fear-driven capitulation and late selling after prices had already declined. Another accumulation phase emerged between May and October 2025, with repeated inflows in the hundreds of millions and some days exceeding $1 billion. Bitcoin rose during the stronger 2025 inflow period before retreating later. From late 2025 into 2026, ETF flows turned less consistent. Bitcoin weakened in early 2026 as negative flows returned, then partly stabilized alongside renewed inflows. Recent readings include inflows of $300 million to $700 million, while one recent outflow approached $450 million. Santiment said Sept. 3's surge fits a broader pattern of sharp back-and-forth ETF flows and warned that another round of withdrawals could follow Bitcoin's mild retracement.
