Rigetti Computing (RGTI +11.50%) stock has risen 81% over the past year at the time of writing, significantly outperforming IonQ (IONQ +20.16%), whose shares are up 31%. This is despite IonQ scaling much faster over the past two years, generating substantially higher revenue. However, Rigetti’s recent launch of its new, more capable quantum computing system could be a catalyst for accelerating growth and narrowing the gap with IonQ over the next few years. Rigetti Computing: Struggling to Grow Revenue Rigetti primarily builds quantum computers and the superconducting quantum processors that power them, integrating these machines into various public, private, or hybrid clouds through its centralized services. Despite launching its largest quantum system and selling a new processing unit to the University of Saskatchewan, it recorded an operating loss of $22.6 million for the quarter ended Dec. 31, 2025. NASDAQ: RGTI Key Data Points IonQ: Accelerating Revenue Trajectory IonQ develops general-purpose quantum computing systems and generates revenue by selling access to these machines through several major commercial cloud providers and its own dedicated service. It expanded operations by acquiring SkyWater Technology, a pure-play semiconductor foundry, and reported an operating loss of $228 million for the quarter ended Dec. 31, 2025. NYSE: IONQ Key Data Points Why Revenue Matters for Investors Revenue is an important measure of how much cash a business collects from selling goods and services. Growth in revenue, or lack thereof, reflects a company's ability to attract customers, deliver its services, and expand its core business operations over time. Image source: The Motley Fool.
