After spot Bitcoin ETFs opened for trading in the USA in January 2024, investors had more than a dozen options. The market was expected to witness fierce competition with the participation of major players such as BlackRock, Fidelity, Ark Invest, Bitwise, VanEck and Franklin Templeton. However, after approximately 18 months, the outlook gradually turned into a structure in which two large funds came to the fore.
The weight of the entries was collected in two funds
Data shows that BlackRock’s iShares Bitcoin Trust fund IBIT and Fidelity’s Wise Origin Bitcoin Fund fund FBTC have become decisive in institutional capital inflows. The impact of smaller-scale funds on the total market direction remained limited.
There was a total of $840.6 million in net inflows into spot Bitcoin ETFs on January 14. Of this amount, $648.4 million went to IBIT and $125.4 million went to FBTC. Thus, the two funds alone collected more than 90 percent of the total inflows on the day.
A similar picture was seen on April 17. Total daily net inflow reached $663.9 million, while IBIT attracted $284 million and FBTC attracted $163.4 million. The two funds together accounted for nearly two-thirds of new money across the industry.
| History | Total net inflow | IBIT | FBTC |
|---|---|---|---|
| January 14 | $840.6 million | $648.4 million | $125.4 million |
| 17 April | $663.9 million | $284 million | $163.4 million |
| May 1 | $629.8 million | $284.4 million | $213.4 million |
On May 1, total net inflow was 629.8 million dollars. IBIT attracted $284.4 million and FBTC attracted $213.4 million, resulting in a combined inflow of approximately $500 million. This trend was repeated throughout most of 2026, with the significant portion of inflows on high allocation days concentrated in these two funds.
Data reveals that investors are increasingly concentrating their Bitcoin ETF preferences on the largest and most liquid products.
Scale came to the fore in a weak market
This concentration has become evident during a challenging period for Bitcoin and the broader crypto ETF market. Bitcoin has fallen approximately 29 percent since the beginning of the year. This decline tested the attitude of institutional investors and brought about multiple withdrawal waves on the ETF side.
There were several days between mid-May and early June that saw high outflows in spot Bitcoin ETFs. While withdrawals in Bitcoin were considered as buying opportunities in previous periods, recent data pointed out that a more cautious approach has come to the fore in investor behavior.
Despite this, IBIT seems to have become the flagship product of the industry. While the fund recorded the highest inflows on most days, it played a stabilizing role during periods of increased market pressure. On some days when the broader ETF group saw sharp outflows, IBIT either remained in positive territory or experienced more limited outflows than its rivals.
Small issuers left behind
This picture also reflects the priorities of large institutional investors. For buyers such as financial advisors, registered investment advisors, hedge funds, family offices and retirement advisors, not only access to Bitcoin but also liquidity, transaction volume and the reputation of the issuer are decisive.
BlackRock manages over $10 trillion in assets worldwide. Fidelity, on the other hand, has one of the largest retirement and brokerage networks in the USA. This distribution power and brand influence have made the two funds the default choice for many investors.
By contrast, Franklin Templeton’s EZBC fund, VanEck’s HODL fund, Valkyrie’s BRRR fund and WisdomTree’s BTCW fund trade with single-digit million-dollar inflows or outflows most days. For this reason, the impact of these products on the total market direction remains limited.
Instead of a broad issuer competition, a structure in which scale, liquidity and distribution power determine investor decisions and the winner gets the biggest share comes to the fore.
Although Bitwise’s BITB fund and Ark’s ARKB fund were once considered strong competitors, today they are in a secondary position behind the two largest products in the market. Additionally, Trump Media & Technology Group withdrew from its planned spot Bitcoin ETF initiative earlier this year. This step showed that competitive conditions are becoming more difficult in the market, which is becoming increasingly crowded but concentrated in two large providers.
