In the U.S. spot bitcoin exchange-traded fund (ETF) market, BlackRock is cementing its No. 1 position with an overwhelming share. As institutional money flows in in earnest through regulated ETFs, an analysis says concentration toward a small number of large asset managers has become more pronounced.

According to blockchain media outlet BeInCrypto on April 6, about 25 asset managers currently offer cryptocurrency products in the form of ETFs, trusts and funds in 2026, but the top five managers are effectively leading assets of more than $100 billion. The market is centred on spot bitcoin ETFs, with total assets under management (AUM) exceeding about $86 billion.

Among them, BlackRock’s iShares Bitcoin Trust (IBIT) manages about $51.9 billion, accounting for about 45 percent of the total. Its net inflows in the first quarter of 2026 were also $8.4 billion, far ahead of rivals. Including ethereum products, BlackRock’s crypto ETF exposure approaches $60 billion.

Second-ranked Fidelity manages about $12.8 billion, centred on the Wise Origin Bitcoin Fund (FBTC). It is drawing institutional money on the back of its in-house custody infrastructure and a fee structure of around 0.25 percent. Its first-quarter net inflows were also $4.1 billion, second only to BlackRock.

Grayscale, which pioneered the early market, is maintaining its presence with the Bitcoin Trust (GBTC). However, momentum has slowed following large outflows in the past, and it appears to be defending its position with the low-fee Bitcoin Mini Trust (BTC). GBTC’s outflows in the first quarter of 2026 were $1.2 billion, slowing compared with monthly outflows of several billion dollars in 2024.

Bitwise is rapidly expanding its market share by diversifying its product lineup. It manages more than $15 billion in assets through more than 40 products and has stood out in altcoin areas such as spot solana ETFs. Bitwise’s solana staking ETF, BSOL, posted AUM of $500 million in just 18 days after trading began.

Galaxy Digital is seeking differentiation with a model closer to a full-service investment bank than a pure ETF issuer. It has grown platform assets to $12 billion by combining wealth management and investment banking functions, but profitability volatility remains a challenge.

Competition among issuers is also becoming increasingly intense. With fee cuts emerging as a key variable, some assessments say around 0.24 percent is the benchmark.

Against this backdrop, Morgan Stanley has been cited as a wildcard that could shake up the market landscape. Morgan Stanley filed an amended S-1 for its spot bitcoin ETF, MSBT, and presented a fee of 0.14 percent. That is lower than existing products including BlackRock’s 0.25 percent.

In addition, considering Morgan Stanley’s roughly $8 trillion wealth management network, its impact is expected to be significant. Some also raise an analysis that even allocating just 2 percent of client assets could generate demand worth $160 billion.

In 2026, the cryptocurrency market is being rapidly reshaped into an ETF-centred structure led by a small number of large managers. With BlackRock’s dominance, fee competition and institutional inflows are combining, and the fight for leadership on Wall Street is expected to intensify further.
