During an interview with CNBC on Thursday, January 18, 2024, Sonnenshein projected that, ultimately, only two or three ETFs would remain in the financial market.

Some days leading up to the US Securities and Exchange Commission’s approval of 10 spot Bitcoin ETFs on January 10, many of the potential ETF issuers slashed their trading fees to attract investors and compete aggressively in the market. These reductions ranged from approximately 0.2% to 0.4% for most ETFs, with Bitwise offering the cheapest rates.
Grayscale opted not to participate in this fee-slashing rally, maintaining its existing 1.5% fee for its ETF, the Grayscale Bitcoin Trust (GBTC). Consequently, GBTC currently boasts the highest trading fees in the market.
Sonnenshein explained the reasons behind GBTC’s relatively high trading fees, emphasizing Grayscale’s position as the largest bitcoin issuer with over a decade of successful operation and a diverse investor base.
The CEO highlighted that investors consider crucial factors such as track record and liquidity when choosing an ETF product to determine the issuer’s credibility. He asserted that investors are likely to favour investment firms with a proven track record, which many newly launched ETFs lack.
“Grayscale is a crypto specialist. And it has really paved the way for a lot of these products coming through,” Sonnenshein reportedly stated.
Despite having approximately $23 billion in assets under management (AUM), GBTC is notably underperforming compared to other recently approved spot Bitcoin ETFs. It has experienced five consecutive days of negative net flows despite its high transaction volumes.
The ETF market is becoming crowded
The Bitcoin ETF competition is also part of a much larger expansion in exchange-traded products.
More than 1,000 new ETFs had launched in the U.S. by the end of August 2026, according to FactSet data cited by Investopedia. The surge has created intense competition across everything from traditional funds to leveraged, thematic and crypto-related products.
The SEC has also begun reviewing how it regulates ETFs as increasingly complex products enter the market. The agency opened a public comment period in June covering products including crypto-linked ETFs, leveraged funds and event-based products.
What happens next for Bitcoin ETFs?
Since the first spot Bitcoin ETFs launched, access is no longer the main problem. Investors now have a growing list of products offering exposure to the same underlying asset. The competition is shifting toward fees, liquidity, scale and distribution.
That could lead to consolidation if smaller funds fail to attract enough assets to remain commercially viable.
For Grayscale, the challenge is different from when it first pushed for a Bitcoin ETF. The company has already secured its place in the market. Its task now is defending that position as cheaper products and major traditional asset managers continue to enter. The future of the Bitcoin ETF market may therefore involve fewer dominant products rather than an ever-growing number of funds.
