Billionaire Investors Make Major Moves in Quantum Computing Stock

Rigetti US76655K1034

Shares of quantum computing firm Rigetti Computing opened the week with significant momentum on Monday. The surge in interest follows the disclosure of prominent hedge funds' latest portfolio holdings, revealing substantial new investments from several billionaire-led firms during the third quarter of 2025.

Recent regulatory filings show a coordinated accumulation of Rigetti stock by major institutional players. Israel Englander’s Millennium Management added 522,100 shares to its position, while Ken Griffin’s Citadel Advisors acquired 51,700 shares. Steven Schonfeld’s fund also initiated a new position, purchasing 8,900 shares. Market participants interpret this concentrated buying activity as a powerful vote of confidence in the company’s long-term trajectory.

Rigetti’s current market valuation stands at approximately $7.84 billion. This figure is notable for a company that reported third-quarter revenue of just $1.95 million, underscoring the premium investors are placing on its future potential within the high-growth quantum computing sector.

Financial Foundation and Technology Roadmap

From a balance sheet perspective, Rigetti maintains a solid position. As of the end of September, the company held liquid assets of $558.9 million, a reserve that exceeded expectations. This substantial war chest provides management with ample runway to aggressively fund research and development efforts as it works to scale its superconducting qubit processors.

The competitive landscape in quantum computing is intensifying. While companies like Alphabet have demonstrated "verifiable quantum advantage" with chips such as Willow, specialists like Rigetti are pursuing alternative architectural paths. Rigetti’s focus remains on superconducting qubits, a different approach from competitors like IonQ, which utilizes trapped ion technology.

The company has outlined ambitious technical milestones, with a 100-qubit system slated for release by the end of 2025. Its roadmap further targets the development of a system boasting over 1,000 qubits by the end of 2027. The market’s current valuation will likely be tested against the company's ability to deliver on these promised benchmarks.

Analyst Outlook: Significant Upside Projected

Coinciding with the hedge fund activity, analysts released bullish projections for Rigetti on Monday. A TipRanks analysis identifies the company, alongside IonQ and D-Wave, as a likely beneficiary of the accelerating quantum computing race. Experts on Wall Street forecast share price appreciation of at least 60% over the next twelve months, with some models calculating upside potential exceeding 100%.

The consensus rating firmly leans toward "Buy," with six analysts currently recommending purchase of the stock. Price targets vary, with Wedbush Securities setting a $35 target and Mizuho projecting a more optimistic $50. Rigetti shares were trading at $23.94 at the time of publication. The coming months will determine whether the conviction of these major investors is well-founded.
