IonQ is showing strong growth with a 222% year-over-year revenue increase and a projected revenue range of $106 million to $110 million for 2025. The company also has a contracted backlog of $141.1 million, indicating future revenue visibility. With no debt and a cash balance of $3.5 billion, IonQ is in a good financial position. On the other hand, D-Wave Quantum’s quantum annealing technology has seen success in real-world applications, with revenues soaring nearly 100% year over year to $3.7 million in the third quarter. While both companies have rich valuations, IonQ seems to offer a better risk-reward profile for long-term investors.
