Live: Complete Rigetti (RGTI) Q3 Earnings Coverage

Rigetti Computing (Nasdaq: RGTI) reports after the close. The stock trades as a high-beta proxy on progress toward practical quantum advantage, so tonight’s focus is less about headline beats and more about proof points on chiplet-based scaling, fidelity, and speed. Management has framed a three-to-four-year journey to quantum advantage, with 2025 positioned as a year to cross the 100-plus-qubit threshold while sustaining 99.5% median two-qubit gate fidelity. Commercial momentum remains concentrated in government and research contracts, leaving quarterly revenue sensitive to program timing and U.S. policy flow.

What to Expect When Rigetti Reports

Key Areas to Watch

• Chiplet performance, fidelity, and speed- Management disclosed Cepheus-1-36Q, a four-chiplet system hitting 99.5% median two-qubit gate fidelity, plus a plan to release a 100-plus-qubit chiplet system at the same fidelity before year-end. They also indicated gate speeds are trending from ~70 ns toward the 50–60 ns range, with sub-50 ns as a target for data-center-class hybrid computing. Updates here are core to the thesis.

• Timeline to quantum advantage- Rigetti continues to frame the requirement set as roughly 1,000+ qubits, 99.9% two-qubit fidelity, <50-ns gate speeds, and real-time error correction, with a ~4-year path viewed as the fastest realistic industry timeline. Any acceleration signals or intermediate milestones will matter for sentiment.

• Government demand and policy cadence- Revenue is concentrated in U.S. and U.K. government research programs. Management pointed to the NQI reauthorization process and DARPA’s QBI program as important demand drivers, with near-term order timing influenced by appropriations. Tonight’s color on pipeline, on-prem opportunities, and program timing is key.

• Balance sheet, OpEx, and runway- Rigetti ended Q2 with ~$571.6 million in cash, cash equivalents and investments, no debt, and completed $350 million of ATM equity sales during the quarter. Expect discussion of OpEx trajectory and hiring pace versus R&D milestones, plus any guardrails on share count following the raise.

• Ecosystem and manufacturing partners- Watch progress with Quanta on control systems and broader hardware stack integration aimed at future higher-volume, lower-cost production. Clarity on when Quanta-built controls enter the flow and how that supports scaling past a few hundred qubits will be a useful leading indicator.
