Around 2,000 institutional investors reported holding Bitcoin in their first quarter 2026 filings, up from around 1,975 in the previous quarter. This suggests that two years after spot Bitcoin ETFs launched in the United States, they have become a popular option among professional investors looking to gain exposure to the largest cryptocurrency.
The introduction of spot ETFs in January 2024 removed many of the regulatory and operational hurdles that previously made pension funds, asset managers, endowments and financial advisors hesitant to invest at scale. Instead of setting up their own digital asset custody infrastructure, investors can now purchase Bitcoin through the same brokerage accounts they have used for years.
Spot Bitcoin ETFs hold real Bitcoin and issue shares that closely track its price, minus management fees. This structure allows institutions to integrate Bitcoin into their existing investment, compliance and reporting frameworks. Holdings can be disclosed in quarterly 13F filings alongside stocks, settled through traditional market structures, and supervised within established institutional policies.
Before Spot ETFs: Custody and Private Key Challenges
Before the existence of spot ETFs, institutions wishing to invest in Bitcoin had to hold their own private keys, which control access to the digital assets. Losing these keys meant losing access to the cryptocurrency. Businesses have also had to deal with evolving accounting standards, custody requirements, and compliance policies that were not designed for cryptocurrency ownership.
Alternative investment vehicles had their own problems. The Grayscale Bitcoin Trust often traded at significant premiums or discounts to the true value of its Bitcoin holdings. Futures-based ETFs provided only indirect exposure and came with rolling futures costs. Neither gave institutions a regulated way to access the Bitcoin spot.
Spot ETFs solve the custody problem, but concentrate the risks
Spot ETFs have solved one of the industry’s biggest challenges: custody. Instead of protecting private keys themselves, investors rely on qualified custodians who hold Bitcoin in “cold” wallets that are offline and less vulnerable to cyber threats.
However, this has led to a concentration of childcare services among a few companies. SatsIntel, a research firm, reports that Coinbase Custody holds assets for nine of the twelve spot Bitcoin ETFs in the United States, representing approximately 84% of the Bitcoin held by these funds.
Fidelity is an exception, using its own Fidelity Digital Assets as a custodian for its FBTC fund. BlackRock also diversified by adding Anchorage Digital, the first federally chartered crypto bank, as an additional custodian of its IBIT ETF. SatsIntel believes this reduces dependence on a single vendor.
Survey shows growing, but cautious, institutional confidence
The results are consistent with regulatory filings. A January 2026 survey of 351 institutional decision-makers by Coinbase and EY-Parthenon found that two-thirds already own cryptocurrencies through spot exchange-traded products. Notably, 81% prefer to obtain spot exposure through regulated investment vehicles.
The survey also revealed growing confidence, tempered by discipline. Nearly three-quarters of respondents said they were willing to allocate more to crypto within a year, while 49% felt their risk management, liquidity control and position sizes had improved. However, the continued lack of clear regulation could hamper further increases in benefits. Clearer rules could lead to greater institutional participation.
Commercial activity and global ownership demonstrate greater acceptance
Trading data supports acceptance of spot ETFs. BlackRock’s IBIT accounts for approximately 75% of the trading volume in the U.S. spot Bitcoin ETF market, giving institutions enough liquidity to execute large trades during normal market hours.
Evidence of institutional ownership extends beyond the United States. As of May 2025, Bitcoin ETFs hold over $109 billion in assets. Notable investors include Mubadala, Abu Dhabi’s sovereign wealth fund, which owns $408.5 million in Bitcoin ETFs; Future of Hong Kong with around $700 million; and the Brown University endowment with approximately $5 million. Although small compared to major asset managers, Brown’s investment is noteworthy because it shows that conservative institutional investors are starting to feel comfortable with Bitcoin as a market option.
Future regulatory filings will reveal whether more institutions will grow beyond the current 2,000-plus investors. Fund issuers will also closely monitor changes to custody, aiming to balance operational efficiency with the risks of over-reliance on a single custodian. These two trends combined will provide a clearer picture of how institutional adoption of Bitcoin is evolving in the ETF spot market.
