McKinsey recently found that quantum companies generated more than $1bn in revenue in 2025.
Honeywell International-backed Quantinuum has filed for an initial public offering (IPO) less than a year after a $600m round valued it at $10bn. Reports suggest that an IPO could raise more than $1.5bn for Quantinuum and value the company at as much as $20bn.
The round comes after the Irish-founded Horizon Quantum and Canada’s Xanadu went public in March, following the US-based Infleqtion a month prior. Meanwhile, shares at D-Wave have grown more than 115pc since last year; IonQ, by nearly 55pc; and Rigetti Computing, by around 84pc, all reflecting the technology’s rising popularity as commercial adoption ramps up to reach a ‘tipping point’.
The UK-founded, Colorado-based Quantinuum produces full-stack quantum platforms with commercially deployed systems. Its products are used by businesses across sectors including pharmaceuticals, materials science, financial services and governments, it said. The company has multiple sites in the US, as well as in the UK, Germany, Japan and Singapore.
