Quantum Computing Race: IonQ vs. Rigetti

What happened: In the quantum computing race, IonQ has taken the lead with its trapped-ion technology achieving 99.99% 2-qubit gate fidelity and generating $64.7 million in Q1 2026 revenue, a 755% year-over-year increase. Rigetti, using a superconducting approach, offers faster gate speeds but lags commercially with just $4.4 million in Q1 revenue. Despite strong growth, IonQ's stock has fallen 58% from its high, valuing the company at around $13 billion.

Market impact: The recent tech sell-off has affected quantum computing stocks, including IonQ and Rigetti. While IonQ's commercial lead drives investor interest, its high valuation and expected losses may deter some. Rigetti's faster gate speeds could attract customers seeking performance over accuracy, but its lower revenue may hinder growth.

What to watch next: Investors should monitor IonQ's full-year revenue growth guidance, expected to exceed 100% organically. Rigetti's Q2 2026 earnings, slated for late July, will provide insight into its commercial progress. Additionally, both companies' technological advancements and partnerships will be crucial to track, as they could significantly impact the quantum computing landscape.
