Ethereum News Today: Institutional Bet on Ethereum Boosts Fidelity's Crypto Holdings by $3B

Fidelity's digital asset custody portfolio expanded by $3.02 billion in the third quarter of 2025, rising from $45.13 billion on July 1 to $48.15 billion by September 30, according to analysis by Finbold. The growth was driven primarily by Ethereum, with Fidelity's ETH holdings increasing from 625,770 to 853,380 tokens, adding nearly $1.97 billion in value as prices surged from $2,502 to $4,139. This marked a stark contrast to Bitcoin, where custody balances fell by 4,160 BTC despite a price increase from $108,383 to $112,162. The shift reflects institutional clients rotating toward Ethereum exposure, signaling a broader trend of diversification beyond Bitcoin dominance in the crypto market.

The Q3 growth followed a mixed first half of 2025. In Q2, Fidelity's portfolio expanded by $11.05 billion, driven by Ethereum's 131,560-token increase and Bitcoin's $10.43 billion gain. However, Q1 saw a $5 billion decline in holdings due to price slumps and reduced balances, particularly for Ethereum. Year-to-date as of September 30, Fidelity's crypto custody assets had grown by $9.54 billion, with Ethereum accounting for over 350,000 tokens of the rebound. This resilience underscores Ethereum's role as a key driver of institutional adoption, particularly as smart contract platforms gain traction.

Comparative analysis with other major players highlights Fidelity's steady but modest growth. During the same period, BlackRock's crypto portfolio expanded by $22.46 billion, rising from $79.63 billion to $102.09 billion. While Fidelity's $3.02 billion increase represented less than one-seventh of BlackRock's growth, both firms prioritized Ethereum in Q3, reflecting shared institutional interest in decentralized finance (DeFi) and tokenized infrastructure. Fidelity's continued expansion in Ethereum, however, positions it as a significant player in custody services, even as it trails larger competitors.

Year-to-date data reveals an even more pronounced trend. As of August 20, Fidelity's combined holdings in the Fidelity Bitcoin ETF (FBTC) and Fidelity Ethereum ETF (FETH) surged by 26.1%, adding $5.37 billion in value. Bitcoin's holdings fell slightly in volume but gained $3.76 billion in value due to price appreciation. Meanwhile, Ethereum's token holdings rose 62%, pushing its valuation from $1.55 billion to $3.16 billion-a 103.9% increase. These figures highlight Ethereum's outsized role in institutional portfolios, with Fidelity's broader custody assets reaching $46.21 billion as of August 20, up from $36.22 billion at the start of 2025.

The institutional shift toward Ethereum aligns with broader market dynamics. Q3 2025 saw U.S. legislative clarity for stablecoins and DeFi, with the GENIUS Act and CLARITY Act reshaping regulatory oversight. Ethereum's dominance in smart contract platforms and DeFi infrastructure positioned it to benefit from these developments. Additionally, declining exchange-held Ethereum balances and rising ETF inflows suggest sustained institutional demand. Analysts note that while Bitcoin remains the cornerstone of crypto portfolios, Ethereum's growth in both volume and value reflects its evolving role as a foundational asset in the digital economy.

Fidelity's performance in 2025 underscores the accelerating integration of crypto into traditional finance. With over $45 billion in digital assets under custody, the firm has solidified its position as a major player in institutional crypto services. The firm's strategic focus on Ethereum, coupled with the broader market's regulatory and technological advancements, signals a maturing industry. As spot ETFs deepen their presence in U.S. capital markets, Fidelity's growth trajectory-anchored by Ethereum-positions it to benefit from ongoing institutional adoption.
