Rigetti Computing Shares Jump 42% Amid Quantum Computing Momentum

Rigetti Computing (RIGT) posted a 42% gain in trading activity during the week ending March 1, 2026, marking one of the most significant weekly swings in the semiconductor and high-growth tech sector. The rally coincided with the company’s announcement of a new 128-qubit processor prototype, which achieved a 99.1% gate fidelity—exceeding industry benchmarks for fault-tolerant quantum operations. This advancement positions Rigetti as a competitive player in the emerging quantum hardware landscape. The surge reflects a broader revaluation of quantum computing as an infrastructure play, particularly as demand for AI-driven computational power intensifies. Investors are increasingly viewing quantum capabilities as a strategic differentiator, especially in tandem with advancements in AI accelerators from firms like NVIDIA (NVDA) and AMD. Market analysts note that RIGT’s valuation now exceeds $2.1 billion, up from $1.5 billion at the start of the quarter, indicating rising institutional interest. The rally has also spurred a 17% increase in trading volume over the past five days, with over 22 million shares changing hands—a 280% spike compared to the 30-day average. This heightened activity suggests growing participation from both retail and institutional investors, particularly those targeting long-term exposure to next-generation computing technologies. As quantum computing moves closer to practical applications in drug discovery, financial modeling, and optimization, Rigetti’s progress is being watched closely by technology investors. The company’s partnership with a major U.S. national lab to develop quantum-classical hybrid systems has further bolstered market confidence. Meanwhile, the stock’s performance stands in contrast to the broader tech index, which saw minimal movement, underscoring the niche yet high-potential nature of quantum investments.
