Rigetti Computing Stock Could Plunge 50% in Second Half of 2026 Despite Government Funding

Summary · why it matters

Rigetti Computing stock could drop by 50% or more in the second half of 2026 due to an elevated valuation, inconsistent revenue, and steep losses, even after the U.S. government announced a $100 million investment over three years as part of a broader $2 billion initiative across nine quantum computing companies. Rigetti's flagship Cepheus-1-108Q system, with 108 qubits, achieves a single-qubit gate fidelity of 99.9% but a two-qubit fidelity of only 99.1%, meaning it still makes too many errors for most real-world applications, and the company says a system with 99.9% two-qubit fidelity could be three years away. Revenue jumped 198% year over year to $4.4 million in the first quarter, but it declined in 2025, and the company posted a GAAP net loss of $20.5 million in the quarter following a $216 million loss in 2025. With a market capitalization of $7 billion, Rigetti trades at a price-to-sales ratio of 663, far above SpaceX's 137.8, and even based on a consensus 2026 revenue estimate of $23.6 million, its forward price-to-sales ratio is nearly 300. The company had $569 million in cash and short-term investments as of March 31, but a capital raise within the next couple of years could dilute shareholders.

IBM Wins $1 Billion Commerce Award as Anderon Quantum Foundry Begins Production

IBM secured a finalized $1 billion award from the Commerce Department for its Anderon subsidiary, which is now operating a 300-millimeter quantum-wafer foundry in Albany, New York. IBM is committing another $1 billion of its own capital to the project, bringing newly disclosed commitments to $2 billion, with the federal government covering half of that total. Initial wafers have already entered production at the facility, which is designed to manufacture technology for superconducting qubits, input-output signaling and readout components, with additional quantum architectures expected to follow. The funding split reduces how much IBM must fund itself while potentially turning Anderon into manufacturing infrastructure for outside quantum-chip designers. IBM shares gained approximately 0.2% to $237.87 Thursday morning, about 2% below the $242.72 GF Value estimate, though IBM has not yet disclosed customers, purchase commitments, wafer volumes or expected Anderon revenue.

IBM's Anderon Finalizes $1 Billion CHIPS Act Quantum Foundry Award

Anderon, an IBM subsidiary, finalized a $1 billion research-and-development award from the U.S. Department of Commerce on Wednesday under the 2022 CHIPS and Science Act. The funding will support Anderon's efforts to advance quantum wafer manufacturing at its facility in Albany, New York, where a 300-millimeter quantum wafer foundry serves customers across the quantum industry. IBM has put up $1 billion of its own money alongside the federal award, and production is underway with quantum wafers already in process. The Anderon award is part of a broader $2 billion package distributed across nine quantum computing companies under the CHIPS and Science Act, with GlobalFoundries in line for $375 million and D-Wave Quantum, Rigetti Computing, and Infleqtion each expected to receive $100 million; each of the nine firms will give the federal government a minority ownership stake in exchange for the funding. The finalization follows a letter of intent between IBM and the Commerce Department announced in May, and last week Rigetti Computing, D-Wave Quantum, and Quantinuum each finalized $100 million deals with the department. IBM stock fell 3.3% on Wednesday and has declined nearly 19% this year.

Mitsubishi Electric Launches Two Quantum Computing R&D Projects Selected by NEDO

Mitsubishi Electric Corporation announced that two of its research and development projects have been selected through a public solicitation by Japan's New Energy and Industrial Technology Development Organization, or NEDO, for support under an initiative to advance quantum computing and other information technology in the post-5G era. The NEDO project is officially known as the Research and Development Project to Strengthen Post-5G Information and Communication System Infrastructure, Accelerating the Development and Demonstration of Next-Generation Quantum Computers to Solve Societal Issues. Following the selection, Mitsubishi Electric will launch its two projects aimed at scaling up quantum computers: Research and Development of Multi-Qubit-Control Laser Systems, and Development of Ultra-Compact, Multi-Channel, Low-Noise Amplifier Modules for Large-Scale Superconducting Quantum Computers. The company said quantum computers are expected to revolutionize computing infrastructure by enabling larger-scale simulations and optimization than conventional computers in fields including medicine and drug discovery, finance, logistics and energy. Because qubits are fragile and highly susceptible to noise, technologies that combine multiple qubits are needed to correct errors, making scaling to the level of one million qubits a key challenge.
