Public quantum computing companies are thriving with a collective valuation exceeding $36 billion, while startup investment has cooled considerably. Quantum startups have raised $1.2 billion so far in 2026, a sharp decline from last year's record $4.1 billion despite continued deal activity.

Recent funding rounds highlight continued investor interest in select players. Vancouver-based Photonic secured $200 million at a $2 billion valuation, while Dutch QuantWare raised $178 million in Series B funding. London's Quantum Motion also attracted $160 million for its cost-efficient quantum computing approach.

The market consolidation continues through acquisitions and IPOs. IonQ acquired Oxford Ionics for $1.08 billion, while D-Wave purchased Quantum Circuits for $550 million. Quantinuum, majority-owned by Honeywell, is preparing to go public with a pre-money valuation of $10 billion, signaling continued confidence in quantum's long-term potential.
