## Summary

**Market Insight:** Bitcoin rose 1.01% in the last 24 hours to $63,706.83.

The U.S. spot Bitcoin ETF market is characterized by significant concentration, with BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) emerging as the dominant players. As of early 2026, IBIT commands approximately half of the U.S. spot Bitcoin ETF market by assets under management, while FBTC maintains a substantial secondary position. These firms have attracted significant institutional interest, with total assets across all spot Bitcoin ETFs exceeding $102 billion and collective holdings surpassing 1.3 million BTC.

While IBIT is noted for its high liquidity, trading volume, and options ecosystem, FBTC is distinguished by its use of in-house custody through Fidelity Digital Assets. Other competitors, such as the ARK 21Shares Bitcoin ETF (ARKB) and newer entrants like Morgan Stanley’s MSBT, continue to operate within the market, though they hold smaller shares of total assets. The market remains competitive regarding fee structures, with expense ratios varying across providers to attract both retail and institutional investors.

## Key points

- BlackRock's IBIT leads the spot Bitcoin ETF market, holding approximately $58 billion to $67 billion in assets depending on the reporting period.
- Fidelity's FBTC ranks as the second-largest spot Bitcoin ETF, utilizing its own Fidelity Digital Assets arm for custody.
- Combined, U.S. spot Bitcoin ETFs hold over 1.29 million BTC, exceeding the holdings of any single private entity.
- Market competition is driven by differences in expense ratios, which range from 0.14% to 1.50%, as well as liquidity and institutional integration.
- IBIT accounts for nearly 45% of total net inflows into spot Bitcoin ETFs during the first quarter of 2026.
