Quantinuum Raises $1.68 Billion in Nasdaq Listing After Record 2025 Quantum Funding

Quantinuum completed a Nasdaq IPO in June that raised $1.68 billion at $60 per share, with shares debuting at $68. The listing followed a November 2025 Series B round of $838.9 million at a $10 billion pre-money valuation. Venture capital investment in quantum computing totaled $3.9 billion across 125 deals in 2025, the highest annual figure recorded, Fortune reported citing PitchBook.

Q3 2025 alone accounted for $1.6 billion, while Q1 2026 brought in another $1.2 billion. BlackRock deployed $1.7 billion and Nvidia deployed $1.6 billion into quantum investments. The venture growth stage captured 30.4 percent of quantum deal value in 2025, up from roughly 1 percent the prior year.

PsiQuantum closed a $1 billion Series E in September 2025 at a $7 billion valuation, led by BlackRock, Temasek, and Baillie Gifford. Cumulative global government commitments to quantum now exceed $60 billion. China’s 15th Five-Year Plan, adopted in early 2026, placed quantum at the top of its future industries list and included an estimated $17.5 billion National Guidance Venture Fund.

Four quantum exits in Q1 2026 by Xanadu, Infleqtion, Quantum Circuits, and Horizon Quantum Holdings totaled $5.7 billion. The median quantum deal size in 2025 was $9 million while the average reached $50.4 million. Most quantum companies have gone public through SPAC-style reverse mergers rather than traditional IPOs.

PitchBook senior AI analyst Dimitri Zabelin said companies such as Nvidia are aware of market scrutiny when selecting investment themes. He added that quantum physicists are scarce and that future systems will likely combine quantum with AI rather than operate independently.
