Bitcoin spot ETFs recorded $723.1 million in net inflows on Sept. 3 after Bitcoin broke above $80,000. Santiment Intelligence said the surge marked the largest single-day inflow since January, while recent ETF activity has remained mixed. The data covers ETF flows from January 2024 through mid-2026, alongside Bitcoin’s price movements.
ETF Inflows Surge After Bitcoin Breakout
According to Santiment Intelligence, ETF buyers moved quickly after Bitcoin cleared $80,000. The firm said such large inflows can reflect traders entering after prices have already risen.
Santiment also highlighted June 26, when Bitcoin ETFs recorded a major outflow near a market low. The firm linked that session to fear, capitulation and late selling after prices had already fallen.
Meanwhile, the latest flows have alternated between gains and withdrawals. Santiment said another wave of ETF outflows could emerge after Bitcoin’s mild retrace.
Institutional Flows Shift Across Market Cycles
The broader data shows several periods of heavy ETF activity since January 2024. Early 2024 featured frequent inflows and outflows, with some inflows above $500 million. ETF activity increased from October 2024 into early 2025.
Several inflow sessions reached $800 million to $1 billion, while the largest visible inflow approached $1.35 billion. However, withdrawals also reached roughly $700 million to $1 billion during that period.
The figures showed large institutional transactions moving in both directions. Another accumulation period developed between May and October 2025. Inflows repeatedly reached several hundred million dollars, with some sessions exceeding $1 billion.
Recent Flows Remain Mixed Into 2026
Bitcoin’s price climbed during the stronger 2025 inflow period before retreating later. From late 2025 into 2026, ETF flows became less consistent. Bitcoin also declined during early 2026 as negative ETF flows returned.
The market later showed partial stabilization alongside renewed inflows. The latest data includes inflows between $300 million and $700 million. However, one recent outflow approached $450 million.
Santiment’s Sept. 3 figure therefore stands within a broader pattern of sharp two-way ETF flows. The firm expects impatient ETF traders could withdraw funds following Bitcoin’s recent retrace.
