Quantinuum IPO Targets $12.7B Valuation on Nasdaq
The quantum-computing company plans to raise up to $1.05 billion as it tests investor demand after cutting its target from earlier whispers.
On Tuesday, Quantinuum, the Broomfield, Colorado-based quantum-computing company majority-owned by Honeywell, filed for a U.S. IPO targeting a valuation of up to $12.7 billion, planning to raise up to $1.05 billion by selling 21.05 million shares at $45 to $50 apiece on Nasdaq under ticker "QNT".
Heightened investor attention around quantum computing, driven by the technology's promise to solve complex problems exponentially faster than classical supercomputers, has accelerated sector funding, with the Trump administration announcing $2 billion in equity stakes across nine quantum companies including a $100 million grant for Quantinuum.
Quantinuum reported a net loss of $192.6 million on revenue of $30.9 million in 2025, compared with a net loss of $144.1 million on revenue of $23 million a year earlier, though its trapped-ion qubits offer a longer error-correction runway than the superconducting approach used by most quantum competitors.
Honeywell will retain about 49.1% of combined voting power and remain a customer and partner post-IPO, while the listing marks the largest quantum-computing IPO to date and the first direct transition from frontier hardware development to a $10 billion-plus public valuation.
At $12.7 billion, the valuation is about 36% below the $20 billion whisper and disciplined relative to private-market marks, reflecting how public investors have proven more disciplined on pre-revenue frontier physics companies than late-stage private rounds had assumed, with comparable peers IonQ, Rigetti and D-Wave trading well below this mark.
