I Tracked Bitcoin ETF Flows: Here’s What They Signal

Key Points:

  • Across all 170 sessions of 2026 on the Farside Investors tape, a $100 million day of net US spot-ETF creation moves Bitcoin 53.7 basis points.
  • The impact does not reverse. Twenty sessions after a top-decile creation day Bitcoin is flat to slightly higher, not back where it started.
  • My call: Bitcoin holds $77,000 to $81,500 into the 15-16 September FOMC.
In this article:

Bitcoin rose 25% in August and the argument since has been whether the $3.5 billion that went into the spot ETFs was cause or coincidence. I measured the coefficient, and had it backwards for a day before my own reversal test corrected me. Below: what a dollar of ETF money is worth, why a number that works is still no use on a Tuesday, and where it sits into the Fed.
