US spot Bitcoin ETFs absorbed just under $1 billion in a single day on Monday, the ninth-largest inflow since the funds began trading in January 2024 and the strongest since October of last year. On-chain flow tracker Lookonchain put the figure even higher in its own tally of the day's activity, showing Bitcoin ETFs adding roughly 14,613 BTC, worth about $1.26 billion, alongside a seven-day net inflow of 8,277 BTC.
BlackRock's IBIT accounted for the largest share of the reported $998.95 million total at $381.4 million, its fourth-highest daily intake on record. Ark and 21Shares' ARKB added $289.1 million and Fidelity's FBTC brought in $238.8 million, with Grayscale, Bitwise and Morgan Stanley funds also posting positive flows. All six major spot Bitcoin ETFs closed the day in the green, a rarer occurrence than the headline total alone suggests.
Ethereum ETFs saw a comparable surge. Spot ETH funds pulled in $269.98 million, their largest single-day total since early October last year, while Lookonchain's separate tracking showed Ethereum ETFs adding 68,434 ETH ($187.93 million) on the day, even as the same funds remained down 32,923 ETH over the trailing week.

The inflows arrived alongside a sharp move in the underlying asset. Bitcoin briefly touched $87,300 on Monday, its highest level since January 2026, before settling near $85,400, up 4.7% over 24 hours. Ether traded around $2,730, up 2.5% on the day.
Analysts pointed to a mix of factors rather than one single catalyst. Presto Research's Min Jung described the move as reflecting “renewed risk appetite, strong spot ETF demand and some short covering after bitcoin broke above key technical levels,” while Zeus Research's Dominick John called it part of “a broader repricing of risk, underpinned by renewed institutional allocation, short-covering activity, and a more supportive macro backdrop.” BTSE's Jeff Mei tied the rotation back into crypto to easing Treasury yields, softer oil prices and this week's Trump-Xi meeting in Washington, while ViaBTC's Jeff Ko framed it more mechanically as a technical breakout above the $82,000 resistance level that triggered systematic trading strategies to add exposure.
Monday's haul pushes September's month-to-date inflow total to roughly $1.31 billion, building on August's $3.52 billion. That pace remains well short of the record months earlier in the ETFs' history, but it marks a clear reversal from the outflows and choppy demand that characterized much of the summer. Bitcoin's push through key price levels earlier this year had already forced a wave of short liquidations, and Monday's ETF data suggests spot demand is now reinforcing rather than lagging behind the price action.
The renewed institutional bid also lines up with continued corporate accumulation. Strategy's own buying activity has kept corporate treasuries in the conversation alongside ETF flows as a source of structural demand, even as the two channels move somewhat independently of each other week to week.
Whether the renewed appetite holds through the rest of the week will likely depend on how markets digest the ongoing Trump-Xi talks in Washington and any further movement on the interest rate outlook. A repeat billion-dollar day would put September on pace to challenge August's total; a quick reversal would suggest Monday's number reflected a short covering event rather than a durable shift in positioning.
