Spot BTC ETF Cumulative Inflows metric
Overview
Spot bitcoin ETF flows measure the net creations minus redemptions across the US exchange-traded funds that hold bitcoin directly, and are widely used as a proxy for institutional and brokerage-channel demand. The first US spot bitcoin ETFs began trading in January 2024, after court rulings compelled the SEC to reconsider its earlier denials — most notably Grayscale's win at the U.S. Court of Appeals for the D.C. Circuit on 29 August 2023. BlackRock's iShares Bitcoin Trust (IBIT) launched in that first cohort and by May 2024 had become the world's largest bitcoin fund, with nearly $20 billion in assets. Flow data is reported per issuer on a daily basis and is aggregated by trackers such as Farside, SoSoValue and CoinGlass.
