Rigetti Computing (RGTI) sells quantum computing systems into a market its own management describes as early, making a straightforward investment case nearly impossible to construct.
Traditional valuation tools like price-to-earnings ratios are useless here because Rigetti continues to lose money, leaving investors with few conventional anchors.
The more useful measure is the price-to-sales multiple, which divides a company’s market value by its last twelve months of revenue.
RGTI currently trades at 399 times sales, compared to just 3.1 times for the S&P 500, meaning sales would need to grow roughly 129 times from current levels to close that gap at today’s share price.
Revenue remains counted in millions rather than billions, which is why the multiple looks enormous rather than merely elevated.
The recent directional trend, however, offers some encouragement, as management reported second-quarter 2026 revenue of about $5.1 million, up from $1.8 million a year earlier, driven by on-premises Novera QPU sales.
Gross margin also improved to approximately 43% in the quarter, up from 31% in the prior year period, suggesting the unit economics are gradually moving in the right direction.
The longer revenue record is less flattering, with Rigetti’s sales contracting at an average annual rate of about 2.4% over the last three years, slipping from $14.4 million to $13.4 million, while the S&P 500 grew revenues at a 5.8% annual clip.
Management attributed the uneven revenue profile to the timing of system deliveries and government-funded project milestones, both of which can create lumpy, unpredictable recognition patterns.
Profitability remains a significant concern, with the operating margin over the last twelve months sitting at -728%, compared to a positive 18.6% for the S&P 500, while operating expenses reached $30.3 million in the most recent quarter.
Shares currently trade at $15.99, which is already 72% below the 52-week high of $56.34, and the stock lost 20.0% over the last twelve months while the S&P 500 gained 17.0%.
RGTI also carries above-average downside volatility, having fallen 32% peak to trough during the 2025 US tariff shock, compared to a 19.0% decline for the broader index during the same period.
The liquidity position does provide some cushion, as management said the company ended the second quarter with about $541.3 million in cash, cash equivalents, and available-for-sale investments, while continuing to operate with no debt.
The competitive argument management offers is specific and notable: only three gate-based quantum systems above 100 qubits exist in the world, located at IBM, Google, and Rigetti respectively.
Management also argues that its chiplet-based architecture represents a more practical path to 1,000 qubits than monolithic designs, though coherence time remains the primary constraint on gate fidelity.
On the funding side, a key uncertainty was resolved when the company finalized a $100 million definitive agreement with the U.S. Department of Commerce under the CHIPS Act in September 2026.
A concrete near-term catalyst also exists in the form of an $8.4 million C-DAC order for a 108-qubit system in India, which management expects to recognize as revenue in the fourth quarter of 2026.
Management is additionally targeting a median two-qubit gate fidelity of approximately 99.5% on its Cepheus-1-108Q system later in 2026, a technical milestone that could influence how the market prices future growth.
Investors willing to buy RGTI today at 399 times sales are, in effect, betting that those technical and commercial milestones materialize faster than the current revenue trajectory would suggest.
Whether that bet is rational depends entirely on how much weight a buyer places on the architecture argument versus the hard math of what each dollar of current sales actually costs.
