Rigetti's Quantum Breakthrough Boosts Stock 1.38% as $580M Trading Volume Ranks 192nd

On August 12, 2025, Rigetti Computing (RGTI) rose 1.38% with a trading volume of $0.58 billion, ranking 192nd in daily trading activity. The company announced the general availability of its 36-qubit multi-chip quantum computer, Cepheus-1-36Q, which achieved a 99.5% median two-qubit gate fidelity—a 2x reduction in error rates compared to its prior system. The launch underscores Rigetti’s proprietary chiplet-based architecture, enabling scalable quantum computing with enhanced performance and manufacturing efficiency.

Financially, Rigetti reported Q2 2025 revenue of $1.8 million, a $39.7 million net loss, and operating expenses of $20.4 million. Despite losses, the firm strengthened its balance sheet with a $350 million equity raise, boosting cash reserves to $571.6 million. CEO Dr. Subodh Kulkarni emphasized the company’s confidence in hitting end-of-year technology goals, including a planned 100+ qubit system by 2025. Rigetti’s chiplet strategy aligns with its roadmap for quantum advantage and fault tolerance, leveraging mature semiconductor technologies to reduce complexity and improve yields.

The 100+ qubit system, expected to maintain 99.5% fidelity, positions Rigetti to advance practical quantum applications. With no debt and a robust cash position, the firm is well-placed for R&D and potential strategic collaborations. However, sustained operating losses highlight the challenges of scaling quantum infrastructure ahead of commercial revenue.

A backtested strategy of purchasing the top 500 stocks by trading volume and holding for one day yielded $2,340 in profit from 2022 to the present. The maximum drawdown of -15.3% occurred on October 27, 2022, reflecting market volatility inherent in short-term trading approaches.
