MARKETS: U.S. spot $BTC ETFs draw $999M on Monday, biggest one-day inflow since $BTC's $126K record on Oct. 6, 2025

U.S. spot BTC ETFs recorded $999M of net inflows on Monday, the largest daily intake since BTC's prior all-time high. The scale and timing of demand signals renewed institutional risk appetite and improved market depth via regulated vehicles, which can tighten available spot supply and support near-term sentiment across crypto. Flow strength also tends to influence derivatives positioning and broader digital-asset correlations.
