Fidelity's crypto holdings climb by $3 billion in Q3 2025 – Finbold report

Fidelity's cryptocurrency holdings surged by over $3 billion during Q3 2025, marking significant growth in institutional Bitcoin and digital asset adoption. The financial giant's crypto custody services expanded from $45.13 billion on July 1 to $48.15 billion by September 30, representing a 6.7% quarterly increase according to Finbold research data.

This substantial growth in Fidelity's digital asset portfolio underscores the continued institutional embrace of cryptocurrency investments and blockchain technology. The $3+ billion increase reflects broader market confidence in Bitcoin, Ethereum, and other major cryptocurrencies during the third quarter.

Fidelity's expanding crypto custody business positions the firm as a major player in the institutional cryptocurrency space, competing with other traditional financial services providers entering the digital asset market. The quarterly growth demonstrates how established financial institutions are increasingly integrating cryptocurrency solutions and DeFi-adjacent services into their offerings.

This development signals continued mainstream adoption of digital assets, with institutional investors driving significant capital flows into the cryptocurrency ecosystem. Fidelity's substantial crypto holdings growth may influence other major financial institutions to expand their blockchain and cryptocurrency service offerings.
