Quantum computing just went from academic curiosity to Wall Street darling. Global venture capital investment in the sector hit $3.9 billion across roughly 125 deals in 2025, the highest annual total ever recorded, according to PitchBook data.
The crown jewel of that spending spree: PsiQuantum’s $1 billion Series E round in September 2025, led by affiliates of BlackRock alongside Singapore’s sovereign wealth fund Temasek and investment firm Baillie Gifford. NVentures, Nvidia’s venture arm, also participated. The deal valued PsiQuantum at $7 billion post-money.
The numbers tell a clear story
Q3 2025 alone saw $1.6 billion flow into quantum computing deals. Q4 2025 added another $1.5 billion.
Why crypto investors should care
BlackRock hasn’t just been writing checks to quantum startups. The firm has also published research analyzing what quantum computing means for blockchain technology and digital asset security.
The core concern centers on elliptic curve cryptography, the mathematical foundation that secures virtually every blockchain in existence. Bitcoin, Ethereum, and nearly every other major network rely on the assumption that certain mathematical problems are too hard for classical computers to solve in any reasonable timeframe.
Quantum computers running Shor’s algorithm could, in theory, break that assumption.
Several blockchain projects are already working on quantum-resistant cryptography, sometimes called post-quantum cryptography. The National Institute of Standards and Technology has been standardizing post-quantum cryptographic algorithms, and some blockchain developers have started integrating them.
BlackRock’s ETF play adds another layer
In December 2025, BlackRock launched the iShares Quantum Computing UCITS ETF, giving traditional investors a simple way to get exposure to the sector.
