Rigetti Computing ( (RGTI) ) has shared an announcement.
On April 7, 2026, Rigetti Computing announced the general availability of its 108-qubit Cepheus-1-108Q quantum system, now accessible via Rigetti Quantum Cloud Services and Amazon Braket as the industry’s largest modular quantum computer based on a chiplet architecture. The system, which triples the qubit count of Rigetti’s prior 36-qubit machine, is currently achieving a 99.1% median two-qubit gate fidelity at roughly 60 ns gate speed and 99.9% median single-gate fidelity, validating the company’s scaling strategy and strengthening its position in cloud-delivered, high-speed superconducting quantum hardware.
Cepheus-1-108Q incorporates key engineering advances, including enhanced qubit and coupler designs, upgraded control electronics, and an advanced fabrication process that shifts performance limits from coupler behavior toward qubit coherence times. By being the first gate-based device with over 100 qubits on Amazon Braket and offering improved fidelities for deeper circuits in areas such as materials science, optimization, and quantum simulation, the launch is expected to deepen Rigetti’s partnership with AWS and broaden its appeal to global enterprise, government, and research users of quantum computing services.
The most recent analyst rating on (RGTI) stock is a Buy with a $33.00 price target. To see the full list of analyst forecasts on Rigetti Computing stock, see the RGTI Stock Forecast page.
Spark’s Take on RGTI Stock
According to Spark, TipRanks’ AI Analyst, RGTI is a Neutral.
The score is held down primarily by weak financial performance (shrinking revenue, margin compression, widening losses, and ongoing cash burn) and bearish technicals (below key moving averages with negative MACD). These are partially offset by a more positive earnings-call outlook driven by a strengthened cash position, specific near-term deployment milestones, and defined revenue-recognition timing for recent orders.
