As of Q3 2025, IonQ reported a revenue increase of 222% year-over-year, totaling $39.9 million, exceeding expectations by 37%. The company achieved a milestone of 99.99% two-qubit gate fidelity and plans to ship its Tempo system in 2026, alongside significant contracts with the Department of Energy. Conversely, Rigetti’s Q3 results showed modest financial traction, booking $5.7 million in purchase orders and securing a $5.8 million contract with the Air Force, while targeting a 150+ qubit system by end-2026.
IonQ enhanced its cash position to approximately $3.5 billion with a $2 billion equity offering, whereas Rigetti aims for a more modular approach to scaling its systems, having already released a 36-qubit multi-chip system. In terms of stock performance, Rigetti shares rose by 69.4% over the past three months, outperforming IonQ’s 13.6% gain and the S&P 500’s 5.7% growth.
Estimates for IonQ’s 2025 loss per share have climbed from $1.77 to $5.14, while Rigetti’s loss estimate changed from $0.09 to $0.68. Both companies are considered speculative investments with a Zacks Rank of #3 (Hold) as they approach 2026.
