Honeywell‑backed quantum computing firm Quantinuum raised its IPO size ahead of its Nasdaq debut (ticker: QNT). The company now plans to offer 26.5 million shares at $53–55 per share** , raising up to **$1.46 billion at a **$14.3 billion valuation** . Earlier terms were 21.1 million shares at $45–50 (up to $1.05 billion).

The upsized offering follows a recent US government initiative that awarded $2 billion in equity investments to nine domestic quantum firms, including **$100 million for Quantinuum** . Quantinuum was formed in 2021 through the merger of Honeywell’s quantum division and Cambridge Quantum, and today has nearly 700 R&D personnel. Unlike many quantum startups that went public via SPAC, Quantinuum chose a traditional IPO path.

Honeywell will retain 48.1% voting power after the offering.
