IonQ posts 755% revenue surge but remains unprofitable on adjusted EBITDA in Q1 2026

Quantum computing company IonQ reported a 755% year-over-year revenue increase to $64.7 million in Q1 2026, beating guidance by 30%. Despite this growth, IonQ posted a net income of $805.4 million largely due to warrant valuation gains, while its adjusted EBITDA showed a $96.8 million loss, reflecting ongoing unprofitability. The company raised its 2026 revenue forecast to $260-$270 million but expects an adjusted EBITDA loss between $310 million and $330 million for the year. IonQ plans to continue heavy investments in R&D and market expansion, supported by $3.1 billion in cash and investments.
