US spot Bitcoin exchange-traded funds shed $89.9 million on Monday, ending a two-day inflow streak as Bitcoin slipped below $86,000 and traded within a day of the one-year anniversary of its October 2025 all-time high.

According to SoSoValue, the outflow trimmed cumulative net inflows into US spot Bitcoin ETFs to $57.7 billion, a 5.8% decline from roughly $61.3 billion. Bitcoin's record of $126,080 was set on Oct. 6, 2025; the asset traded at $85,559 at the time of publication, per CoinGecko, leaving it down 32% from that peak.

How deep did Monday's flows run?

The reversal came after the spot Bitcoin ETF complex absorbed approximately $293 million across the previous two October trading sessions. Aggregate trading volume across the 11 spot products reached $2.2 billion on Monday, SoSoValue data shows.

Are Ether ETFs keeping pace with the Bitcoin retreat?

US spot Ether (ETH) ETFs recorded approximately $51 million in net outflows on Monday, extending a five-session losing streak. The funds have shed a combined $206 million over that stretch, with cumulative net inflows now standing at $13.8 billion, according to SoSoValue.

What did altcoin ETFs do on the same day?

The Monday session produced mixed results across other single-asset products:

• Solana (SOL) funds recorded $9.3 million in net outflows.
• Zcash (ZEC) funds recorded $3.6 million in net outflows.
• XRP ETFs reported zero net flows after posting $3.3 million in outflows on the prior Friday.

What comes next for the spot complex?

The pullback landed one session before Bitcoin's all-time-high anniversary and against a backdrop of broader cooling in crypto risk appetite. With BTC sitting 32% below its 2025 peak and cumulative inflows down 5.8% from their plateau, SoSoValue's next daily flow print will determine whether Monday's outflow marks a one-day tremor or the leading edge of a more sustained institutional retreat.
