Bitcoin will retain 80-85% of ETF market share – Analyst reveals how

• BTC ETFs could dominate 85% of the market share when altcoin ETFs go live. 
• Benjamin Cowen expects BTC dominance to soar to 66%. 

Bitcoin [BTC] would retain a massive market share amongst institutions, despite the potential of altcoin ETFs (exchange-traded funds).

According to Bloomberg analyst Eric Balchunas, the altcoins would be a ‘minor dent.’ He stated, 

“Bitcoin ETFs command 90% of all the crypto fund assets globally. While a ton of alt/memecoin ETFs are likely going to hit market this year, they will only make minor dent, Bitcoin likely to retain at least 80-85% share long-term.”

Per the attached chart, overall BTC ETFs have $110 billion in assets under management (AUM) while ETH products control $7 billion (5% of market share) as of April 2025. 

BTC dominance soars

The current ETF share slightly mirrors the top assets’ current spot market size. ETH market share has dropped to 7% from 19% peak levels in 2024. On the contrary, BTC dominance surged to 64.5% from 50% (including stablecoin market cap). 

In fact, analyst Benjamin Cowen echoed Balchunas’ projection. He stated that BTC could extend its outperformance against altcoins and hit 66%. 

“I think that ALT/BTC pairs will continue to bleed here, just like they did last year when the Fed announced they would slow Quantitative Tightening (QT). BTC dominance to 66%.”

That said, the U.S. spot BTC ETFs recorded sustained sell-offs in 2025. Under tariff uncertainty, over $4 billion was withdrawn from the products between February and April.

However, on the 21st of April, the products logged $381 million in daily inflows, the highest since February. The renewed interest in BTC followed a U.S. dollar sell-off and flight to gold and the digital asset as ‘safe havens.’ The total net assets stood at $97 billion. 

In the meantime, at the time of writing, BTC exchanged hands at $88.4K.

The next step would be clearing the 200-day Moving Average (MA) at $88.3K and the previous range-low at $92K to maintain the recovery.
