Quantum Stock Surge: Why Rigetti (RGTI) and Sector Peer Stocks Are Skyrocketing

TradingKey - There's a trade that's been lighting up the market lately. One of those trades is none other than Rigetti Computing (NASDAQ: RGTI). After being trapped in a tight consolidation through mid-May, this stock jumped 30% in one day to $22.10. This wasn't an isolated event, however. Quantum stocks continue building momentum on the back of three main catalysts: record government investments, rapid movement towards commercialization, and a turn-around from the most influential semiconductor executive in the world. Analysts covering RGTI rate the stock Buy, with an average price target of $30, or a 40% premium over current levels.

Three Reasons Why Quantum Stocks Are Rising Today

It's not just Rigetti – other pure play quantum computing stocks like IonQ (IONQ), D-Wave Quantum (QBTS), and Infleqtion are on fire too. There's a good reason for that – this rally isn't a squeeze or meme rally. Here are the three main catalysts responsible for the recent surge in quantum computing stocks:

1. Government Makes Record Investments in Quantum Computing

The first catalyst came in the form of a headline that broke on May 21. Specifically, the Trump Administration declared $2 billion to be distributed by way of Commerce Department grants to nine quantum computing firms in exchange for minority government stakes in them. These CHIPS and Science Act grants constitute the biggest federal investment in quantum computing hardware in history.

The largest grants went to IBM, which will receive $1 billion in return for building a quantum chip manufacturing factory that will match the investment. Secondly is GlobalFoundries, which received $375 million. All other firms – D-Wave Quantum, Rigetti Computing, Quantinuum, and Infleqtion – will each receive $100 million each. To quote the words of Secretary of Commerce Howard Lutnick, "we are leading the world into a new era of American innovation."

Why is this important for Rigetti? Well, the fact that these are record-breaking grants for quantum computing means great things from the monetary aspect but also from an operational point of view.

First of all, the grants help Rigetti achieve its ambitious goal of delivering utility-scale quantum computers in three years' time. By Q1 2026, Rigetti had $569 million in cash on hand. Nothing in liabilities. Now that Rigetti will be able to add another $100 million to its balance sheet and secure a government equity stake in the company, Rigetti will reach its ambitious milestones much faster, according to CEO Subodh Kulkarni. "The extra capital will help us tackle our critical scaling challenges."

2. Rigetti Continues Building Toward Commercialization

On May 11, Rigetti Computing reported Q1 2026 earnings which beat analyst expectations on all accounts. Revenue increased nearly two-fold compared to last year and reached $4.4 million (against expected $4.1 million), while the loss per share of $0.04 was exactly as analysts predicted.

What matters more than the numbers is that Rigetti announced the launch of yet another product, its latest generation Cepheus-1-108Q quantum processor, containing 108 qubits of computational capacity and available for sale either via Rigetti Quantum Cloud Services network or via Amazon Braket (AWS). But why should this news be important?

Because Cepheus-1-108Q system represents Rigetti's first commercially viable quantum processor. According to Wedbush analysts, "The release of the Cepheus-1-108Q system represents an important commercial milestone," and given Rigetti's proprietary chiplet design, further scaling is inevitable. As an indication of increasing demand from international governments to satisfy their quantum computing needs, Rigetti has secured an order for a 108-qubit computer from the Center for Development of Advanced Computing of India.

So what should investors consider in relation to RGTI valuation? Rigetti Computing still boasts very thin margins. Last year's trailing revenue came in at just $7.1 million while price-to-sales ratio stood at nearly 746x. Clearly, Rigetti's valuation is highly speculative. However, if everything goes according to plan and Rigetti reaches its growth targets, the valuation will eventually turn positive.

3. Nvidia's CEO Takes a Turn on Quantum Computing

Perhaps the most dramatic news regarding quantum computing in the past year comes from a speech Nvidia's CEO, Jensen Huang delivered during CES in January 2025. Specifically, the following words of his made headlines around the world. "It may take anywhere between 15 to 30 years to have genuinely useful quantum computers." Rigetti and IonQ dropped 45% and 39%, respectively, as shares of other quantum stocks took a tumble.

Fast forward to May 2026, and things seem to be changing quite a bit. Nvidia is introducing its open source AI tool called Ising that aims to turn quantum computers into industrial-scale computers. According to Jensen Huang: "AI is key for developing quantum computers; Ising provides the open-source environment where AI serves as control plane (an 'operating system') of quantum computing machines, which transforms fragile qubits into scalable quantum-GPU systems."

Although Nvidia does not manufacture quantum processors itself, the company has significant influence in the computing industry and can serve as a bridge between quantum processors and GPU-based supercomputers. Both Rigetti and IonQ are partners to Nvidia CUDA-Q hybrid computing system. In addition, Nvidia unveiled its NVQLink technology allowing seamless interaction between quantum processing units and GPU clusters at a latency of just four microseconds.

Moreover, Jensen Huang encouraged Congress to pass legislation extending the National Quantum Initiative, as without quantum computers integrated with AI and high-performance supercomputing, US would lose its technological dominance.

The implications are simple – as Jensen Huang invests time and resources in developing the architecture necessary for quantum computing, we won't wait decades for this technology anymore.

Closing Words

The reason why this particular quantum rally seems to be more credible than others is that all the prerequisites for success seem to have fallen into place. Quantum stocks get record-breaking funding from the government. Products are rolling out. The most influential semiconductor executive in the world supports the trend. It seems that all the pieces of the puzzle finally fit to enable quantum stocks to experience a much-needed re-rating.
