How much money has gone into bitcoin funds, and how has that changed?
Research question: How much money has flowed into bitcoin investment funds, and how has that changed over time?
The records show inflows arriving in large bursts rather than steadily. Grayscale's products took in about $3.3 billion in the fourth quarter of 2020 1, and the first quarter of 2024 saw the 11 spot Bitcoin ETFs draw about $12.1 billion in net inflows 2. The newest figure is that Bitcoin ETFs took in $6.3 billion in net inflows in the third quarter of 2026 13, which is recent relative to October 2026. The facts do not provide a combined running total across all bitcoin funds, only Grayscale's cumulative inflows of nearly $6.9 billion as of 31 December 2020 6. Investors also sold most aggressively near January 2026's peak 14, so the flows have reversed as well as grown.
