What happened

Oratomic, a California quantum-computing startup founded in 2025, raised $475 million in a Series B, lifting its valuation to $5.5 billion from $1.5 billion, SiliconANGLE reports. The round came three months after a $300 million Series A and brings total funding to $775 million. On the same day, UK-based Universal Quantum announced a Series A of more than $100 million (about €89 million), which it and local reports describe as the largest ever raised by a UK-headquartered quantum firm. The two companies use different hardware: Oratomic works with neutral atoms and Universal Quantum with trapped ions.

What we know

SiliconANGLEsiliconangle.comEU-Startupseu-startups.comTech.eutech.eu
  • Per SiliconANGLE, Oratomic's $475 million Series B was co-led by ARCH Venture Partners, Spark Capital, Khosla Ventures, Index Ventures, General Catalyst and Bezos Expeditions, and its valuation rose to $5.5 billion from $1.5 billion.
  • Per SiliconANGLE, the Series B follows a $300 million Series A from about three months earlier and takes Oratomic's total funding to $775 million.
  • Per SiliconANGLE, DCVC and Firgun Ventures co-led Universal Quantum's round of more than $100 million. EU-Startups puts the figure at over €89 million ($100 million), and Tech.eu also reports $100 million.
  • Per Tech.eu and EU-Startups, Universal Quantum, a University of Sussex spinout based in Brighton, says this is the largest Series A raised by a UK-headquartered quantum firm; EU-Startups hedges the claim with 'reportedly'.
  • Per SiliconANGLE, Universal Quantum says it will put the money into its modular chiplet-based approach and its Singapore R&D center, its first outside Europe, plus expansion in the US, Japan and Hamburg, Germany.

What we don't know yet

  • Oratomic says it can reach high-fidelity error correction with about 10,000 qubits, against an industry figure SiliconANGLE puts near 1 million. No independent verification or hardware demonstration is cited in the sources.
  • Whether the $1.5 billion earlier valuation was set at the Series A is not stated in the sources we have; only SiliconANGLE reports the valuation figures, and no company filing is linked.
  • Oratomic's CEO told the Wall Street Journal, per SiliconANGLE, 'We have no idea what the business models are going to be.' Revenue timelines and applications remain unspecified.
  • SiliconANGLE cites a McKinsey estimate of up to $2.7 trillion in value by 2035 and more than $1 billion in 2025 industry revenue. We have not checked McKinsey's report directly, and such forecasts have a long record of shifting.

Why it matters

A reported 3.7x valuation jump in three months for a startup founded in 2025, with no stated product revenue, shows how much venture capital is now betting on fault-tolerant quantum architectures; rivals relying on larger qubit counts face a funded competitor claiming a hundredfold smaller requirement.
