Fidelity’s spot Bitcoin fund had a very good Monday. Clients of the Fidelity Wise Origin Bitcoin Fund (FBTC) bought $103.06 million worth of Bitcoin on October 13, 2026.
That would be a solid day on its own. What makes it stand out is that Fidelity accounted for almost all of the money flowing into US spot Bitcoin ETFs that day.
The entire sector posted net inflows of $109.8 million. FBTC’s haul, tracked at approximately $103.1 million in research data, left the rest of the field to split roughly $6.7 million in net terms.
A big day in a choppy month
The inflows arrived as Bitcoin traded above $86,000.
Firms like SoSoValue and Farside Investors monitor primary market activity for these funds, meaning the shares created and redeemed each day. Those creations matter because a spot ETF has to hold the real asset. When investors pour cash into FBTC, the fund needs actual Bitcoin to back the new shares.
October has not been a straight line. ETF flows swung between inflows and outflows through the early part of the month. On October 1, the sector logged a net inflow of $102.7 million, with BlackRock’s iShares Bitcoin Trust (IBIT) leading the way. Later that same week, FBTC saw outflows.
That pattern is typical for Fidelity’s fund. FBTC is one of the most active products in the category, frequently flipping between sizable inflows and sizable outflows as markets move.
Where FBTC sits in the ETF pecking order
US spot Bitcoin ETFs launched in January 2024. Since then, the group has gathered approximately $57 billion in cumulative net inflows. Total assets across the sector have topped $100 billion at various points this year.
Within that market, FBTC usually ranks just behind IBIT on both assets and trading volume. FBTC charges a 0.25% fee, placing it among the lowest-cost major Bitcoin ETFs alongside IBIT, and that fee has potentially been waived during some periods.
On-chain data helps separate ETF activity from ordinary retail transactions, giving analysts a clearer view of how much demand is coming through these regulated vehicles.
What this means for investors and the ETF race
The concentration is a notable detail. When one fund captures nearly the whole sector’s net inflow, it can mean other products saw flat days or small outflows that offset each other.
FBTC’s own history is a reminder of volatility. The same fund that drew $103.06 million on October 13 saw money leave just days after the sector’s strong October 1 session.
The flow data from SoSoValue and Farside Investors will keep offering a daily scorecard. For now, Fidelity has the bragging rights, and its clients have a fresh $103 million worth of Bitcoin to show for it.
