GQI's 2026 predictions flagged that DARPA will announce which companies participating in Stage B of its Quantum Benchmarking Initiative will be invited to Stage C before the end of 2026. The QBI is one of the most rigorous independent evaluations of quantum computing systems, requiring companies to demonstrate practical advantage on problems of defence relevance.

Stage C selection is not a prize. It is DARPA's judgment about which hardware platforms have demonstrated enough capability to merit continued investment in defence applications. The funnel is expected to remain broad but the companies that advance will have the most credible government endorsement in the sector.

DARPA selection is different from a commercial endorsement because DARPA evaluates against defence-relevant problem specifications that companies cannot game by choosing convenient benchmarks

The companies most likely to advance are the ones with the strongest error correction demonstrations because DARPA's problems require circuit depths that NISQ machines cannot reach reliably

IonQ, Quantinuum, and IBM are the obvious candidates for Stage C but the neutral atom companies including Infleqtion and potentially Oratomic are the dark horse selections that would shift the narrative significantly

Advancing to Stage C changes a company's fundraising environment more than almost any other external validation. Government technical endorsement is the signal that institutional investors who cannot evaluate quantum hardware directly trust most
I'm not always right, but I'm never wrong ;)

The EU Quantum Grand Challenge participants being announced at similar timing creates a parallel evaluation that will produce a different but complementary picture of which approaches are most promising

Stage C selection happening before the Quantinuum IPO would potentially be the most strategically valuable timing for that company. Going public with DARPA Stage C participation is a different story than going public without it
