Fidelity's Wise Origin Bitcoin Fund (FBTC) recorded $103.06 million in client purchases on October 13, 2026, capturing nearly the entire day's inflows for the US spot Bitcoin ETF sector. The broader category logged total net inflows of $109.8 million that day, leaving approximately $6.7 million to be split among competing products.
The concentration underscores FBTC's dominant position within the market. The fund typically ranks second only to BlackRock's iShares Bitcoin Trust (IBIT) by both assets under management and trading volume. Both funds charge among the lowest fees in the category, with FBTC charging 0.25%.
The October 13 inflow arrived as Bitcoin traded above $86,000. October has seen volatile trading patterns across the sector, with flows swinging between significant inflows and outflows throughout the month. On October 1, the entire sector logged $102.7 million in net inflows, with IBIT leading that session. FBTC has historically exhibited similar volatility, frequently alternating between sizable inflows and outflows as market conditions shift.
US spot Bitcoin ETFs launched in January 2024 and have since accumulated approximately $57 billion in cumulative net inflows. Total assets across the sector have exceeded $100 billion at various points throughout the year. Firms including SoSoValue and Farside Investors track primary market activity for these funds, monitoring the creation and redemption of shares daily. This data is significant because spot Bitcoin ETFs must hold actual Bitcoin to back newly created shares.
