New research shows the firm’s cryptocurrency holdings have expanded by more than $5.3 billion year-to-date, underscoring the rapid institutional adoption of Bitcoin and Ethereum in 2025.
At the start of the year, Fidelity’s two spot ETFs — the Fidelity Bitcoin ETF (FBTC) and the Fidelity Ethereum ETF (FETH) — reported combined holdings of over 201,000 BTC and 462,000 ETH, valued at $20.55 billion.
By August 20, those figures had shifted to 199,127 BTC and 728,939 ETH, worth $25.92 billion at current prices. While Fidelity’s Bitcoin stash decreased slightly in unit terms, the surge in BTC’s price from $92,595 to $113,500 boosted its dollar value by nearly $3.8 billion.
Ethereum delivered the real standout performance. Fidelity’s ETH holdings jumped by 62% in tokens and more than doubled in dollar value, soaring from $1.55 billion to $3.16 billion over the same period.
Fidelity’s crypto presence isn’t limited to its ETFs. Its custody division has also seen major growth, safeguarding assets for hedge funds, corporations, and other institutional investors.
Data from Arkham shows Fidelity Custody now manages $46.2 billion in crypto assets, up from $36.2 billion at the beginning of the year. On-chain activity also reveals frequent transfers between Fidelity Custody and Coinbase, highlighting active flows linked to both ETFs and private clients.
With a total digital asset footprint above $45 billion, Fidelity has become a heavyweight in the U.S. crypto market. The growth mirrors a broader trend among Wall Street firms competing for dominance in spot crypto ETFs.
BlackRock, the largest player in the space, has seen even faster expansion — growing its crypto portfolio by nearly $49 billion in 2025 alone, more than doubling assets under management since January.
Fidelity’s steady accumulation underscores how Bitcoin and Ethereum are being integrated into traditional finance at an unprecedented scale. With ETFs gaining traction and custody services expanding, institutional adoption is deepening, signaling that crypto is no longer a fringe asset class but a core part of global capital markets.
