- IonQ traded up 10.5% at $62.77, ahead of gains among other tech and quantum names.
- Quantinuum’s Nasdaq debut last week gave investors a new way to track public trapped-ion quantum stocks.
- IonQ’s May guidance hike is still holding up the trade. But losses and a slow path to commercialization are the main risks here.
IonQ stock rose Monday, last trading up 10.5% at $62.77. Shares moved between $56.66 and $64.90 during the day. That takes the quantum-computing firm’s market cap to about $23.3 billion.
The move gets attention now because there’s a new public-market comp for the quantum business. Quantinuum, the Honeywell quantum arm, pulled in $1.68 billion in a U.S. IPO last week. Shares started trading on Nasdaq as QNT, putting another listed name in quantum—still a thin field.
Growth and tech stocks pushed higher alongside the rally. Reuters said the Nasdaq and chipmakers bounced, leading gains on Wall Street after last Friday’s drop. The S&P 500 tech sector added 1.8%. The Philadelphia Semiconductor Index jumped 6.2%.
IonQ outperformed most other quantum stocks in the area. Rigetti Computing ended up 5.8%, D-Wave Quantum closed 7.6% higher and Quantum Computing Inc was up 4.3%. The Invesco QQQ Trust, which tracks big Nasdaq growth names, gained 1.6%.
Quantinuum started trading at $68, above its $60 IPO price, Reuters reported. The debut puts the Honeywell-backed firm at a $17.63 billion valuation. Both Quantinuum and IonQ run on trapped-ion systems, using lasers on charged atoms for computing, according to Reuters.
Analysts at Wedbush said last week that adding more public quantum stocks might “improve price discovery” and “ripple across listed peers,” Reuters reported. That fits with what happened Monday: IonQ didn’t announce a new contract, this looks like a group reset. Reuters
IonQ’s latest figures come from the May 6 update. Q1 revenue came in at $64.7 million, 755% higher from the prior year. The company raised its 2026 revenue guidance, now $260 million to $270 million. Remaining performance obligations — business contracted but not yet recorded as revenue — climbed 554% year over year to $470 million.
IonQ CEO Niccolo de Masi told Reuters following the results, “Profitability is not a key focus this year,” and said the priority is revenue growth and R&D spend. D.A. Davidson’s Alex Platt said the stock had entered earnings with “high expectations” and there was still skepticism about trapped-ion qubits. Reuters
A qubit is a quantum bit. It handles more complex data than the regular 0-or-1 bit, but qubits are tough to manage and make mistakes easily. That’s still a big challenge for the sector.
Commercialization is moving past the lab, say backers of the bull case. “Commercialization has started,” Quantinuum CEO Raj Hazra told Reuters. IPOX Schuster analyst Kat Liu said investors are interested in the “long-term potential” of quantum computing and its role in national security, AI, communications, and advanced computing. Reuters
But the risk is clear. IonQ is guiding for an adjusted EBITDA loss of $330 million to $310 million in 2026, based on a measure that excludes interest, taxes, depreciation, amortization and other items. If investors see Quantinuum’s IPO as a cap on valuations instead of a floor, IonQ’s premium could come in quickly.
Right now, it’s a straightforward trade: contracts, cash, and a more active quantum tape line up against losses, technical risk, and questions about adoption. On Monday, Wall Street took the first side.
