On Nvidia investing in PsiQuantum

Is Quantum ready for a breakout?

Jensen Huang says quantum computing is far off from being mainstream, but Nvidia seems ready to invest.

Just a little note on Nvidia’s efforts in Quantum. This is a short note for investors.

PsiQuantum is the biggest Quantum semiconductor moonshot company having raised over $1.7 billion and achieving a valuation of $6 billion as of March 2025.

PsiQuantum employs a photonics-based approach called "fusion-based quantum computing" (FBQC). This method utilizes individual photons as qubits and relies on well-established optical technology, though it requires precise manufacturing to scale up.

Nvidia investing in PsiQuantum could deliver a stock market hybe bubble for Quantum computing that could significantly move the needle. This is because Nvidia is on pace to become the most valuable company in the world dominating the AI chip market. Since they are also focusing on Quantum’s capabilities it has profound consequences for the Quantum computing nascent industry.

A Black Rock Party

NVIDIA is reportedly in advanced talks to invest in PsiQuantum as part of a $750 million funding round led by BlackRock, marking its first direct investment in quantum hardware and potentially valuing the company at nearly $6 billion.

Usually this wouldn’t be news but because of the size of the bet of PsiQuantum and the fame of Nvidia, will make many onlookers starting to notice.

The deal would mark Nvidia’s first investment in a company focused on building physical quantum computers. Nvidia is looking into Quantum hybrid datacenters in its partnerships with TSMC, Taiwan and major winners of the Quantum chip race.

Nvidia investing in PsiQuantum and Quantinuum going IPO are the two major events of consequences I see that could rally the Quantum industry into a more hyped and mainstream category. Infleqtion, SandboxAQ, Quantum Machines and others need to think about going IPO too. The timing by around 2026-2028will be right for a Quantum stock rally that makes today’s figures look well, normal. Currently the bell-weather stock for Quantum is IONQ 0.00%↑. As you might know, it’s up 295% in the last year.

Nvidia’s support for PsiQuantum could not just help bridge the gap between theoretical advancements and practical implementation, but mean Quantum stocks become even more elevated leading to an IPO goldrush for the best Quantum startups. This is inevitable, it’s just a question of timing. This is the best thing the VC community around the Quantum industry can do to keep capital flowing into the space and push innovation forwards.

The U.S. stock market is an accelerator, and Nvidia understand this full well now as of 2025. Whatever you make of PsiQuantum, they are a big bet for a nascent industry. A $750 million round for a Quantum startup is not just rare, it’s pretty much unheard of.
