Quick take: In a direct comparison of two public quantum computing plays, IonQ emerges with clearer revenue momentum and margin strength, while Rigetti displays a concerning decline in sales and a valuation that sits well above a Fair Value estimate. Both names are highly volatile and remain speculative investments.
Price and market snapshot
- IonQ (IONQ): $39.71 (up 8.97% on the day), market cap $13.60B.
- Rigetti (RGTI): $16.07 (up 7.46% on the day), market cap $4.97B.
Key valuation and performance metrics line up unevenly across the two companies. IonQ’s modeled Fair Value is lower than its market price by about 18%, while Rigetti appears priced roughly 45% above its Fair Value estimate. Analyst target upside is larger for Rigetti in percentage terms, though that optimism sits against a weakening revenue base.
Revenue and margin dynamics
The clearest distinction between the two businesses is top-line direction. IonQ’s revenue has stepped up sharply over recent fiscal years - moving from $22M to $43M and then to $130M across three fiscal years - and its latest last-twelve-months (LTM) revenue is shown at $187.12M, with analysts projecting roughly $265.02M for the coming year. That rapid scaling supports a speculative premium for a pre-profit technology company and pairs with a gross margin of 36.1%, a figure that suggests some pricing power in its commercial arrangements.
By contrast, Rigetti’s revenue trend is deteriorating. Historical figures show revenue moving from $12M to $10.79M to $7.09M, and the table of recent metrics lists an LTM revenue of $10.02M with a FY+1 revenue estimate of $23.29M. Its gross margin is reported at 30.0% while the firm posts a deeply negative LTM net income margin (-2,253.6%), indicating substantial losses on current operations.
Valuation, earnings and volatility
IonQ’s Fair Value model produces a reference price of $32.56, leaving the stock at about an 18% premium to that estimate. Notably, IonQ’s LTM net margin appears positive in the data, but the analysis flags that this is likely influenced by non-recurring items and that forward EPS remains negative (FY+1 EPS shown at -$1.17).
Rigetti’s Fair Value is shown at $8.80 against the market price of $16.07, implying about a 45% overvaluation by that model. Forward EPS (FY+1) is negative as well (shown at -$0.18). Volatility differs between the two: IonQ’s five-year beta is 3.23, while Rigetti’s is 1.96, and one-year returns in the table show -4.4% for IonQ and +5.9% for Rigetti.
Bull and bear case summarized
- Support for IonQ: accelerating commercial revenue, trapped-ion architecture advantages cited by proponents, and revenue scale that can justify its speculative premium.
- Risks for IonQ: high historical volatility and recent analyst downward revisions to earnings expectations.
- Support for Rigetti: a larger percentage upside in analyst targets and a lower absolute share price that may appeal to some investors seeking optionality.
- Risks for Rigetti: shrinking revenues, a large implied overvaluation versus Fair Value, and a business not yet demonstrating scale.
The bottom line
When judged on current fundamentals, IonQ offers the more credible upside backed by a visible revenue engine and healthier gross margins. Rigetti represents a higher-risk scenario: greater headline upside per analyst targets but a disconnect between that optimism and the company’s recent financial trajectory. Both stocks carry extreme volatility and should be position-sized with that risk in mind.
