Quantum computing remains one of the most speculative corners of the market, with NVIDIA (NASDAQ: NVDA) CEO Jensen Huang previously suggesting large-scale commercialization is at least 15 years away.
Despite the long horizon, operating fundamentals across the publicly traded quantum pure-plays have materially improved in 2026, with stronger bookings, cash positions, and revenue visibility than at any prior point.
All three stocks carry extreme price-to-sales multiples, with reported figures as high as approximately 109 for IonQ, 836 for Rigetti, and 791 for D-Wave, making them aggressive, lottery-ticket-style positions rather than core portfolio holdings.
IonQ (NYSE: IONQ) leads the group by market cap at roughly $20.11 billion, posting Q1 FY26 revenue of $64.67 million, a 755% year-over-year increase that beat the midpoint of its own guidance by 30%.
Management raised full-year revenue guidance to between $260 million and $270 million, pointing to organic growth above 100% year over year as the company accelerates its commercial push.
Remaining performance obligations surged 554% year over year to $470 million, and IonQ secured its first 256-qubit Tempo system sale to the University of Cambridge, marking a shift toward commercial-scale deployments.
CEO Niccolo de Masi called it “the biggest quarter in our company’s history,” though investors should note the stock has already fallen 25% over the past month, with an adjusted EBITDA loss guidance range of negative $330 million to negative $310 million for FY26.
Rigetti Computing (NASDAQ: RGTI), with a market cap of roughly $6.35 billion, is the technology-purity bet of the group, with its 108-qubit Cepheus-1-108Q system now generally available across Rigetti QCS, Amazon Braket, Microsoft Azure Quantum, and qBraid.
CEO Subodh Kulkarni described Cepheus-1-108Q as “one of the most powerful generally available gate-based quantum computers in the world,” achieving median 99.8% two-qubit gate fidelity at 40-nanosecond gate speeds.
Q1 FY26 revenue nearly tripled to $4.40 million from $1.47 million a year earlier, and the company holds $569 million in cash and investments with no debt, funding a planned $100 million UK investment targeting a 1,000-plus qubit system.
Insider selling warrants attention, however, with CTO David Rivas disposing of 499,328 shares at $25.396 on May 29, and Director Ray Johnson selling over 207,000 shares in early-to-mid June.
D-Wave Quantum (NYSE: QBTS), valued at roughly $8.79 billion, stands apart as the only company pursuing both annealing and gate-model quantum computing simultaneously, giving it a broader addressable market than its peers.
Q1 FY26 bookings reached $33.40 million, up nearly 2,000% year over year, anchored by a $20 million Florida Atlantic University system deal and a $10 million Fortune 100 quantum computing as a service agreement.
CEO Alan Baratz stated the company is “uniquely positioned to participate in the full addressable quantum computing market,” with the Quantum Circuits acquisition accelerating its gate-model roadmap toward a 17-qubit dual-rail system in 2026 and 100 logical qubits targeted by 2032.
Headline Q1 revenue of $2.86 million fell 81% year over year, though this decline is mechanical, as the prior-year period included a one-time $12.6 million system sale that inflated the comparison.
Adjusted EBITDA loss widened to negative $32.8 million from negative $6.1 million, and GAAP operating expenses rose 125% year over year, underscoring the cost intensity of scaling a dual-modality quantum platform.
June drawdowns across all three names, with IonQ down 25%, Rigetti down 24%, and D-Wave down 21% on the month, illustrate how rapidly sentiment can shift in this sector.
Q2 earnings in early August will be the next major test of whether bookings momentum is durable or whether the sector is repricing toward the longer commercialization timeline that skeptics continue to highlight.
Investors watching this space should monitor government contract announcements closely, along with any updates on the pending SkyWater and Quantum Circuits integrations, as both could significantly influence near-term price action.
