What Needs To Be True To Buy Rigetti Stock Today

Rigetti Computing (RGTI) sells quantum computing systems into a market its own management calls early, which makes the buy question hard to answer. You cannot lean on earnings, because Rigetti loses money, which leaves its price-to-earnings ratio meaningless. You can measure what you pay for each dollar of sales. Here is that walk, one step at a time.

How Should You Judge What You Pay For Rigetti?

A price-to-sales multiple divides market value by the last twelve months of sales. Take a round-number example, not Rigetti: a company worth $1 billion with $10 million of sales trades at 100 times sales. For that multiple to fall to 10 times without the share price dropping, sales have to reach $100 million. The measure tells you how much future growth the price already assumes. Now run Rigetti through the same steps.

Where Does Rigetti Land On That Same Math?

Rigetti trades at 399 times sales, against 3.1 times for the S&P 500. Run the same step: at today's price, sales must be about 129 times what they are now to reach that 3.1. Sales are still counted in millions, not billions, which is why the multiple is enormous rather than merely high.

The direction is better than the level. On the second-quarter 2026 call, management said revenue was about $5.1 million, against $1.8 million a year earlier, and that the increase came from on-premises Novera QPU sales. Gross margin was about 43% in the quarter, up from 31%.

The longer record is worse. Rigetti's revenue has contracted at an average rate of about 2.4% a year over the last three years-slipping from $14.4 million to $13.4 million-while the S&P 500 grew at a 5.8% annual clip. Management said the revenue profile is influenced by the timing of system deliveries and government-funded projects.

Profitability sits further behind. The operating margin over the last twelve months was -728%, against 18.6% for the S&P 500, so the company spends far more than it takes in. Operating expenses were $30.3 million in the quarter, concentrated in research and development and in investments in refrigeration and infrastructure.

What Could Break Or Support The Price You Pay?

You pay $15.99 a share, or 399 times sales, and that price is 72% less than the 52-week high of $56.34, after the stock lost 20.0% over the last twelve months while the S&P 500 gained 17.0%. The lower price has not made the sales multiple ordinary.

The stock also drops further than the market does. In the 2025 US tariff shock, Rigetti fell 32% peak to trough, against 19.0% for the S&P 500. Management said the company ended the second quarter with about $541.3 million in cash, cash equivalents and available-for-sale investments and continues to operate with no debt, so the near-term pressure is not a funding one.

The case for paying up is specific. Management said only three gate-based systems above 100 qubits exist in the world, at IBM, Google, and Rigetti, and that its chiplet-based architecture is a more practical path to 1,000 qubits than monolithic designs. The doubt comes on the technical side: management notes that coherence time is now the primary constraint on gate fidelity. On the funding front, however, the uncertainty has cleared-the company finalized its $100 million definitive agreement with the U.S. Department of Commerce under the CHIPS Act in September 2026.

So here is a check you can run yourself. The $8.4 million C-DAC order for a 108-qubit system in India is expected to be recognized as revenue in the fourth quarter of 2026, and management is aiming for a median two-qubit gate fidelity of about 99.5% on Cepheus-1-108Q later in 2026. Weigh those two against what you pay for each dollar of sales today.
