Fidelity’s FBTC inflow surge and the competitive ETF landscape

Inflow Momentum

Fidelity Wise Origin Bitcoin Fund (FBTC) captured $310.72 million in net inflows on September 18, a single-day figure that dwarfed other products in the category. On September 18, FBTC pulled in $310.72 million in net inflows, which accounted for roughly 72% of the entire day’s haul across all US spot Bitcoin ETFs during that specific trading session. This single-day amount represented roughly 75% of an entire multi-week accumulation spree. This momentum continued through the following week. The fund added $238.8 million on September 21 and $257.4 million on September 22. On September 22, BlackRock’s iShares Bitcoin Trust (IBIT) led with $350.3 million, while Morgan Stanley’s MSBT added $99 million. The fund recorded another $143.2 million in inflows on September 23. On September 18, IBIT added $108 million. These recent movements contribute to the $11,073 million in cumulative net inflows FBTC has seen since its January 2024 inception. The combined four-session run from September 17 through September 22 totals approximately $2.31 billion for the entire category. On September 22, the total daily inflow reached $714.7 million. Such activity helps support the $102.53 billion in total assets held by US spot Bitcoin ETFs as of mid-September.

Custody and Cost Comparison

Fidelity’s FBTC provides a clear advantage through its proprietary custody model. The fund holds $13,866 million in total assets and maintains a 0.0% portfolio turnover rate. Investors often select FBTC to achieve custody diversification because it uses Fidelity Digital Assets for its holdings. Ten of the twelve spot Bitcoin ETFs rely on Coinbase or Coinbase-affiliated custodians for their Bitcoin. You might find the fee structure a point of contention if you prioritize the absolute lowest cost available. While FBTC carries a 0.25% expense ratio, the Morgan Stanley Bitcoin Trust (MSBT) charges only 0.14% annually. MSBT, which launched on April 8, 2026, became the first spot Bitcoin ETF issued directly by a major US bank. This bank utilizes a network of approximately 16,000 financial advisors managing roughly $6.2 trillion in client assets.

The fund’s size remains substantial compared to newer entrants like MSBT, which holds roughly $300 million in net assets.
