TLDR
- BlackRock’s IBIT and Fidelity’s FBTC captured over 90% of Bitcoin ETF inflows on some days in 2026
- On January 14, the two funds took in $773.8M of a total $840.6M in daily inflows
- Bitcoin is down roughly 29% year-to-date, yet IBIT has acted as a stabilizing force during selloffs
- Smaller funds like VanEck’s HODL and Franklin Templeton’s EZBC regularly see only single-digit million flows
- Trump Media & Technology Group scrapped plans for its own Bitcoin ETF earlier this year
When spot Bitcoin ETFs launched in the U.S. in January 2024, investors had over a dozen funds to choose from. The expectation was fierce competition. Eighteen months later, two firms have pulled far ahead.
The U.S. spot Bitcoin ETF market is starting to look much less competitive than people expected at launch.
BlackRock’s IBIT and Fidelity’s FBTC are now absorbing most of the meaningful inflows while many smaller ETF products are slowly fading into the background.

BlackRock’s iShares Bitcoin Trust and Fidelity’s Wise Origin Bitcoin Fund now dominate the market. On most high-volume days, these two funds capture the majority of all new money flowing into Bitcoin ETFs.
The numbers are hard to argue with. On January 14, 2026, total Bitcoin ETF inflows hit $840.6 million. BlackRock alone took in $648.4 million. Fidelity added $125.4 million. That’s more than 90% of all inflows that day going to just two funds.
The pattern held throughout the first half of 2026. On April 17, total inflows reached $663.9 million. BlackRock brought in $284 million, Fidelity added $163.4 million — roughly two-thirds of the total between them.
On May 1, inflows hit $629.8 million. The two funds again combined for nearly $500 million of that total.
Why Investors Are Choosing These Two Funds
The concentration comes down to a few practical factors. For institutional investors — financial advisers, hedge funds, family offices, and pension managers — liquidity and issuer reputation matter as much as the product itself.
BlackRock manages over $10 trillion in assets globally. Fidelity runs one of the largest retirement and brokerage networks in the U.S. Both firms have deep distribution relationships and established trust with large allocators.
That makes IBIT and FBTC the default choice for many institutions seeking Bitcoin exposure.
Smaller Funds Are Struggling to Keep Up
The story looks very different for everyone else. Funds from Franklin Templeton, VanEck, Valkyrie, and WisdomTree regularly record daily flows in the single-digit millions. Their impact on overall market direction is minimal.
Even Bitwise and Ark Invest, once seen as strong competitors, now sit well behind the two leaders.
Earlier this year, Trump Media & Technology Group withdrew its plans to launch a spot Bitcoin ETF. The move reflected the challenge of entering a market now shaped by the two biggest players.
All of this is happening during a tough stretch for Bitcoin. The price is down about 29% year-to-date. That decline has triggered multiple waves of ETF redemptions, particularly between mid-May and early June 2026.
During those selloffs, IBIT often held steady or saw smaller outflows than rivals. On several days when the broader ETF market posted heavy redemptions, BlackRock’s fund either stayed positive or declined far less than competitors.
The Bitcoin ETF market is increasingly looking like a winner-take-most business. Scale, liquidity, and distribution are driving investor decisions, and right now, BlackRock and Fidelity have all three.
