Summary
The inflow dynamics proved particularly striking. U.S. spot Bitcoin ETFs logged eight consecutive days of net inflows totaling $2.1 billion, representing the longest positive streak since a nine-day run in October 2025. BlackRock's IBIT captured approximately 75% of these inflows, cementing its position as the dominant institutional Bitcoin vehicle in the U.S. market. This sustained capital deployment marked a decisive reversal from a brutal five-week outflow period that had drained roughly $3.8 billion, suggesting a structural pivot in institutional sentiment.
Recent weekly performance showed consistent strength, with Bitcoin ETFs recording $787 million in net inflows in one recent week and $853.54 million in another—the strongest weekly total since mid-April. Individual daily inflows also remained robust, with spot ETFs recording $1 billion in single-day inflows and $556 million in another session. These figures indicate that the rally was not a fleeting event but rather supported by sustained institutional accumulation.
The short-squeeze component amplified the move, as traders with bearish positions were forced to cover, adding additional buying pressure to the upside. Strategy, an identifiable market participant, purchased 950 BTC during this period, reflecting confidence among larger investors. The combination of technical momentum, institutional ETF demand, and the unwinding of short positions created a confluence of positive factors that pushed Bitcoin decisively higher and past the $85,000–$87,000 range for the first time in eight months.
