BlackRock and Fidelity Dominate U.S. Spot Bitcoin ETF Inflows, Sidelining Smaller Funds

BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) have absorbed the majority of new institutional capital into U.S. spot Bitcoin ETFs as the market shifts toward a two-firm structure.

“BlackRock and Fidelity are quietly turning bitcoin ETFs into a two-firm market BlackRock's IBIT and Fidelity's FBTC are attracting the vast majority of new bitcoin ETF money, leaving smaller funds increasingly sidelined as institutional investors consolidate around the industry's largest players”

On January 14, U.S. spot Bitcoin ETFs recorded a net inflow of $840.6 million, with IBIT attracting $648.4 million and FBTC attracting $125.4 million, together accounting for more than 90% of the total.

The same concentration pattern reappeared on April 17, when the overall market saw a net inflow of $663.9 million, with IBIT attracting $284 million and FBTC attracting $163.4 million, together accounting for about two-thirds of the day’s new funds.

On May 1, despite weak market sentiment, ETFs still recorded net inflows of $629.8 million, with IBIT contributing $284.4 million and FBTC contributing $213.4 million—combining to nearly $500 million.

CoinDesk framed the shift as a move away from a multi-manager competitive field, saying the battle increasingly looks like a two-player race as smaller funds become largely irrelevant in determining the direction of the overall market.

Bloomingbit reported that institutional investors remain cautious as spot ETF outflows continue and a recovery in spot demand has yet to materialize.

Diana Pires, chief business officer at digital-asset prime brokerage sFOX, said some buying has emerged after Bitcoin’s recent price decline, but she added that “a meaningful recovery in spot demand has yet to be confirmed.”

Pires also said continued outflows from spot Bitcoin ETFs are keeping institutional investors cautious, while CoinDesk described how the two largest funds often determine whether the sector records net inflows or outflows when investors buy or sell.

CoinDesk tied the concentration to the behavior of IBIT during stress, noting that on several days when the broader ETF complex experienced heavy outflows, IBIT either remained positive or saw far smaller redemptions than its competitors.

The KuCoin report similarly described how, during many periods of volatility, IBIT and FBTC have still maintained net inflows, or their redemption amounts have been significantly smaller than those of other products.

The reports describe the U.S. spot Bitcoin ETF market as consolidating around scale, liquidity, and distribution networks, with smaller issuers losing influence as IBIT and FBTC capture most new inflows.

KuCoin said the daily fund flows for Franklin Templeton’s EZBC, VanEck’s HODL, Valkyrie’s BRRR, and WisdomTree’s BTCW typically amount to only a few million dollars, limiting their impact on overall market direction.

CoinDesk added that funds such as Franklin Templeton's EZBC, VanEck's HODL, Valkyrie's BRRR and WisdomTree's BTCW frequently record daily flows measured in single-digit millions of dollars, leaving their contributions too small to move the market on many trading days.

The KuCoin report also noted that Trump Media & Technology Group withdrew its spot Bitcoin ETF plan earlier this year, abandoning its attempt to enter a market now dominated by leading products.

In the same vein, CoinDesk said the concentration has become particularly noticeable during periods of volatility, as the industry increasingly resembles a sector where the winner takes the majority of the market.
