NEW YORK, June 1, 2026, 12:02 EDT
Rigetti Computing shares moved up about 3.4% to $26.41 by late Monday morning, bouncing back after early weakness. Investors were active on quantum-computing news and last week’s U.S. funding signals. The stock changed hands between $24.12 and $26.47, with over 35 million shares traded before noon in New York.
Rigetti is still in early days, but its market cap has already reached almost $8.8 billion. So any technical update, talk of government funding, or move from rivals tends to move the stock more than it would at a mature hardware name. Broader U.S. stocks hovered near records on Monday as tech gained ground, even with oil prices up and U.S.-Iran tensions in focus.
Latest from Rigetti is research, not a customer contract. A paper in Nature Communications on Monday—by Riverlane and some Rigetti authors—shows real-time, low-latency quantum error correction on superconducting qubits. The team ran an 8-qubit test with as many as 25 rounds of decoding and managed to keep mean decoding time per round under a microsecond.
The market isn’t focused on earnings now, it’s looking for proof. Quantum computers are still mainly research hardware. Error correction is a major hurdle between current noisy setups and something that can actually do practical work at scale.
Rigetti’s share price still shows the effect of recent funding news. The company said on May 21 that it signed a letter of intent with the U.S. Commerce Department for up to $100 million over three years from the CHIPS Act. Rigetti said the government would take an equity stake tied to the funding. CEO Subodh Kulkarni said that support could help Rigetti work through “key scaling bottlenecks.” GlobeNewswire
Rigetti posted Q1 revenue of $4.4 million and an operating loss of $26 million. Cash, cash equivalents and available-for-sale investments totaled $569 million at the end of March. The company said its 108-qubit Cepheus-1-108Q quantum system is now generally available on Rigetti QCS, Amazon Braket, Microsoft Azure Quantum and qBraid. CEO Kulkarni said Rigetti is still focused on “disciplined execution.” GlobeNewswire
D-Wave Quantum laid out a gate-model plan Monday, aiming for 100 logical qubits and more than 1 million operations by 2032. The company describes logical qubits as error-corrected units built from physical qubits. CEO Alan Baratz called it a “credible path” to fault-tolerant quantum computing. Late Monday morning, D-Wave shares were up 2.9%, IonQ was off 0.5%. Peers added to the noise. Business Wire
Quantum stocks are about to get another look from the market. Quantinuum, Honeywell’s quantum arm, increased the target size of its planned IPO to $1.46 billion, Barron’s said Monday. The deal would bring another quantum company with deep backing to public investors.
Rigetti faces a clear bear case. The company’s valuation is built on future milestones that could be far off, with limited revenue and ongoing losses. TD Cowen’s Krish Sankar cut his rating on the stock in February, pointing to a “premium valuation” and the potential need for capital to fund a $200 million fabrication plant, according to TipRanks. Form 144 filings have surfaced again and flagged insider-sale notices for market watchers; these filings signal planned sales of restricted or control shares, not confirmation the shares have been sold.

Rigetti’s next set corporate event is its virtual stockholder meeting, set for June 9 at 9 a.m. Pacific. Until then, trading in the stock should stay driven by funding updates, reports from the lab, headlines from rivals, and a market that’s still attaching a premium to quantum stories.
