Quantum computing stocks jump 12% as peace deal fuels broad rally

Quantum computing stocks surged Monday, with QUBT and QBTS each gaining 12%, after a U.S.-Iran peace deal sparked a broad rally that lifted speculative tech names.

"The move is entirely macro-driven — there's no quantum-specific catalyst today," said Sarah Lin, equity analyst at Edgen. "These names trade as a thematic basket, and when the VIX drops sharply, they tend to outperform on beta."

The S&P 500 tracking SPDR S&P 500 ETF Trust gained 1.67%, while the CBOE Volatility Index fell to 16.24, well below its June 10 intraday peak of 22.22. Rigetti Computing rose 9% to around $22.92, and IonQ added 6% to roughly $61.51. The four names moved in lockstep as a quantum-computing basket, with no company-specific catalyst behind any of the gains.

The rally shows how pre-profit, high-beta names remain tethered to shifts in risk appetite rather than fundamental catalysts. With the formal U.S.-Iran signing expected June 19, traders will watch whether the bid holds into the week's close or fades as an intraday momentum trade.

IonQ Leads on Revenue, but Valuation Remains Steep

IonQ reported Q1 2026 revenue of $64.67 million and raised its full-year guidance to a range of $260 million to $270 million. Still, at a market cap near $23 billion and a price-to-sales ratio of 115 times, the stock trades on expectations rather than current cash flow. The company carries one Strong Buy, 10 Buy, and two Hold ratings from analysts, with an average price target of $67.64.

D-Wave and Rigetti Push Technical Roadmaps

D-Wave Quantum, up 72% over the past 12 months, reported Q1 bookings of $33.4 million and held an investor day at the NYSE on June 1 outlining a gate-model roadmap targeting 100 logical qubits by 2032. Mizuho analyst Vijay Rakesh maintained an outperform rating and raised his price target to $35 from $29, implying more than 20% upside from Friday's close.

Rigetti Computing, up 101% over the past year, posted Q1 revenue of $4.4 million — nearly triple the prior-year period — and narrowed its loss per share to $0.04. Its 108-qubit Cepheus-1-108Q system is available on AWS Braket, Azure Quantum, and qBraid, and management flagged a UK investment of up to $100 million for a 1,000-plus qubit machine.

What to Watch

Quantum Computing Inc., the laggard of the group with shares down 34% over the past year, posted Q1 revenue of $3.69 million, lifted by its February acquisitions of Luminar Semiconductor and NuCrypt. The company holds about $1.4 billion in total cash and investments on its balance sheet.

With no quantum-specific catalyst behind Monday's rally, the action appears driven by macro flows rather than company fundamentals. The next checkpoint for the basket may come from the formal U.S.-Iran signing on June 19 and any fresh sector commentary from upcoming industry events.
