A quantum-computing infrastructure vendor is testing public markets in 2026, but deal size and valuation are still unset.
The filing arrives as DARPA's Quantum Benchmarking Initiative targets utility-scale performance by 2033, with IBM targeting a first fault-tolerant system in 2029. Google and IBM roadmaps illustrate the supply-chain opening SeeQC is targeting as an infrastructure provider.
The registration statement is on its fourth amendment with blank pricing and share-count fields, and there has been no public market for the common stock. Nasdaq listing approval is a stated condition to the offering.
