Quantinuum ended the second quarter of 2026 with $2.1 billion of cash, cash equivalents and short-term investments after completing a $1.7 billion initial public offering, providing the quantum computing company with substantial capital as revenue increased 279% year-over-year.
Q2 revenue reached $8 million compared with $2 million a year earlier. Quantinuum characterized its IPO as the industry’s first traditional initial public offering and said the transaction generated approximately $1.7 billion in gross proceeds.
The company’s adjusted gross margin remained high at 62%, down 60 basis points from a year earlier. GAAP gross margin improved by 27 percentage points but remained negative at 64.4%.
Quantinuum continues to operate at a substantial loss as it invests in quantum hardware, software and commercial expansion. Q2 GAAP net loss reached $597 million compared with $57 million a year earlier, while Adjusted EBITDA loss widened to $68 million from $43 million. Adjusted net loss per share was $0.28.
The large GAAP loss included significant non-cash charges associated with stock-based compensation following the company’s reorganization and remeasurement of liability-classified warrants. Quantinuum said those charges were driven by accounting triggers and external inputs rather than current operating activity.
The company established its first formal full-year guidance as a public company, expecting 2026 revenue of $28 million to $32 million.
Quantinuum is also expanding commercialization of its Helios quantum platform. The company announced a partnership with Oracle to deploy Helios within an Oracle Cloud Infrastructure AI data center, enabling hybrid quantum-AI workloads as an OCI service while integrating with existing compute, networking, storage, identity and data services.
Helios separately demonstrated near five-nines logical fidelity using a new quantum error-correction code family. Quantinuum is advancing its next-generation Sol system toward a planned 2027 launch, while Apollo remains scheduled for 2029.
Quantinuum also entered a strategic collaboration with HPE focused on hybrid quantum, high-performance computing and AI environments and signed a joint development agreement with a major global electronics manufacturer to develop manufacturing capabilities for future quantum systems. Nexus, its cloud-based developer platform, is now being used by 180 organizations.
