Quantum Computing Investment Hits Record Highs as BlackRock Pours Billions into Sector

Quantum computing has emerged as a hot sector in venture capital investment, with $3.9 billion poured into roughly 125 deals in 2025, according to PitchBook data.

The crown jewel of this spending spree is PsiQuantum's $1 billion Series E round, led by affiliates of BlackRock and Singapore's sovereign wealth fund Temasek. NVentures, Nvidia's venture arm, also participated in the deal that valued PsiQuantum at $7 billion post-money.

BlackRock hasn't just been investing in quantum startups; the firm has also published research analyzing the impact of quantum computing on blockchain technology and digital asset security. The core concern is elliptic curve cryptography, which secures virtually every blockchain in existence. Quantum computers running Shor's algorithm could potentially break this assumption.

Blockchain projects are already working on quantum-resistant cryptography, sometimes called post-quantum cryptography. BlackRock has even launched the iShares Quantum Computing UCITS ETF, giving traditional investors a simple way to get exposure to the sector.
