NVIDIA’s Indirect Billion-Dollar Bet on Xanadu Quantum Technologies
April 18, 2026 – 9:58 am
Christian Weedbrook, the founder and CEO of Toronto-based Xanadu Quantum Technologies, became a billionaire this week without NVIDIA investing a single dollar in his company. His 46.4 million multiple-voting shares were worth approximately $1.5 billion as of midday Friday, after Xanadu’s stock surged nearly fivefold in six trading sessions. The catalyst wasn’t anything Xanadu did; it was NVIDIA’s announcements that sent the entire sector into a rally, making Xanadu the most dramatic beneficiary.
NVIDIA’s Announcements and Market Impact
NVIDIA did not buy Xanadu shares or sign any contracts with them. Instead, on April 14, NVIDIA:
- Launched Ising, a family of open-source AI models designed to solve two major challenges hindering quantum computers: error correction and calibration. These models are faster and more accurate than current industry standards.
- Unveiled NVQLink, an open system architecture for coupling GPUs with quantum processing units, supporting various QPU builders, controller manufacturers, and national laboratories.
- Announced the NVIDIA Accelerated Quantum Research Center in Boston, integrating quantum hardware with AI supercomputers.
These moves signified a shift from quantum computing being a research curiosity to an engineering problem, with NVIDIA aiming to bridge classical and quantum systems.
NVIDIA’s venture arm, NVentures, has already invested heavily in other quantum startups: leading Quantinuum’s $600 million Series B round, participating in QuEra Computing’s funding, and joining PsiQuantum’s $1 billion raise.
Xanadu, a photonic quantum computing company, benefited from this broader trend, even without direct investment from NVIDIA.
