Global venture capital investment reached $227.4 billion across 8,440 deals during Q2 2026, according to KPMG's latest Venture Pulse report. This represents the second-highest quarterly total, though it declined from the record $332.9 billion invested in Q1, which was boosted by OpenAI's $122 billion round. US companies received $144.9 billion across 3,644 deals, accounting for nearly 64% of global investment. Major US transactions included a $12 billion round for AI modeling company Project Prometheus and a $5 billion raise by defense technology company Anduril Industries.
Within the quantum-computing sector, investment slowed from the record pace recorded in 2025 but remained active, according to KPMG. Netherlands-based QuantWare raised $178 million, Germany's eleQtron secured $66 million, and Quantinuum raised $1.6 billion through a Nasdaq listing that valued the company at $17.6 billion. According to Galaxy Research, venture firms invested approximately $4 billion across 355 crypto and blockchain deals in Q1 2026, with funding falling 50% from the previous quarter. Trading, exchanges, investing, and lending companies collected approximately $2.6 billion, representing close to three-fifths of the quarterly total.
Moon Pursuit Capital founder Utkarsh Ahuja told crypto.news that investors will need to consider quantum risks well before a computer capable of breaking current blockchain security becomes available. The firm co-led AmericanFortress' $8 million seed round alongside SAVA Digital Asset Fund and 0G Labs. AmericanFortress has developed a proposed security system called ZK-PoSP that would allow wallets to prove control of their original seed without exposing it, covering addresses on Bitcoin, Ethereum, and Solana without requiring holders to move their funds or rotate their keys. Ahuja said the investment was based partly on the product's planned compatibility with infrastructure already used by crypto networks.
The US National Institute of Standards and Technology finalized its first three post-quantum cryptography standards in August 2024, with quantum-vulnerable algorithms expected to be deprecated by 2030 and removed from standards by 2035. In July, Strategy, BlackRock, Coinbase, and six other companies created a Bitcoin security consortium, pledging a combined $15 million over three years. Ethereum Foundation researcher Justin Drake announced that Ethereum's future layer-1 design will move away from the Poseidon hash function and use established functions such as SHA-2 or BLAKE2s, with a production version of leanVM scheduled for 2027 and planned protocol deployments in 2028.
