Rigetti Computing closed late 2025 with more than $600 million in cash and short-term investments, a buffer that management says will fund aggressive research and development initiatives through key qubit-scale milestones. With this level of liquidity, the company can pursue full-stack hardware and software integration without tapping equity markets or issuing new debt, preserving current share count and minimizing dilution risks for existing investors.

Since the start of the artificial intelligence revolution, Rigetti shares have climbed nearly 3,000%, and in 2025 alone the stock advanced approximately 46%. This performance outpaces broader quantum benchmarks, such as the Defiance Quantum ETF, which rose 37% over the same period. The rally reflects investor optimism around Rigetti’s superconducting-qubit architecture and its promise to unlock next-generation AI algorithms inaccessible to conventional GPUs.

Rigetti’s price-to-sales ratio stands at about 925, a level vastly higher than the 51 and 144 multiples seen by Amazon and eBay at their dot-com peaks. While elevated valuation underscores future growth expectations, it also raises the risk of a sharp correction should revenue traction prove slower than anticipated. In prior technology bubbles, heavy multiples often preceded double-digit drawdowns when operating metrics failed to match sky-high investor forecasts.

Through the first nine months of 2025, Rigetti generated just $5.2 million in revenue but incurred $63.4 million in operating losses. Although the semiconductor division shows scalable potential, the company’s burn rate remains substantial relative to its top line. Management’s ability to convert qubit breakthroughs into recurring cloud-access subscriptions will be critical to narrowing losses and validating the current valuation over the next 12 to 18 months.
