Quantum Computing Stocks QUBT, RGTI, and QBTS Rally After Q1 Earnings Reports

Key Takeaways

• Quantum Computing Inc. saw Q1 2026 revenues skyrocket to $3.7 million from a mere $39,000 the previous year
• Rigetti Computing surpassed analyst projections with $4.4 million in Q1 sales, reflecting a 200%+ annual increase
• D-Wave Quantum experienced an 80%+ revenue decline to $2.9 million, yet bookings exploded to $33.4 million
• Despite ongoing losses, each firm maintains substantial cash reserves to support research and development initiatives
• The quantum computing sector is gaining momentum as investors search for the next transformative technology beyond artificial intelligence

The quantum computing sector is experiencing renewed investor enthusiasm following recent quarterly financial disclosures. Three prominent pure-play companies — Quantum Computing Inc., Rigetti Computing, and D-Wave Quantum — have emerged as the most closely monitored stocks in this emerging field.

This heightened attention follows company announcements showcasing expanding revenues, technological breakthroughs, and reinforced balance sheets. However, profitability remains elusive for all three, forcing investors to balance future promise against current financial challenges.

Let’s examine the current standing of each company.

Quantum Computing Inc. (QUBT)

Quantum Computing Inc. posted Q1 2026 revenues totaling $3.7 million. This represents a dramatic increase from the $39,000 recorded during the comparable quarter twelve months prior.

Quantum Computing, Inc., QUBT

This remarkable expansion stemmed primarily from the company’s strategic acquisitions of Luminar and NuCrypt. These transactions not only amplified reported revenues but also generated significant investor interest in the stock.

According to Seeking Alpha, this revenue explosion created positive spillover effects for competing quantum firms such as IonQ, Rigetti, and D-Wave.

The company is simultaneously progressing with its Fab 2 manufacturing initiative, which could prove significant should demand for photonic quantum solutions accelerate. Given its modest size and developmental stage, investors should monitor whether expansion can persist independently of acquisition-driven increases.

Rigetti Computing (RGTI)

Rigetti Computing announced Q1 2026 revenues of $4.4 million, exceeding analyst forecasts of approximately $4.1 million. Revenues climbed over 200% compared to the prior year period.

Rigetti Computing, Inc., RGTI

The company’s adjusted per-share loss also showed improvement, registering $0.04 compared to a $0.08 loss in the equivalent quarter last year.

Rigetti unveiled its 108-qubit platform and maintains a chiplet-based technology roadmap that market observers consider central to its investment thesis.

Financial Resources and Government Partnerships

The company concluded the quarter holding approximately $569 million in cash, providing ample runway for continued innovation. Additionally, it has obtained an $8.4 million contract from India’s Centre for Development of Advanced Computing and previously secured a $5.8 million agreement with the U.S. Air Force.

Rigetti presents a hardware-centric quantum narrative with genuine commercial and governmental momentum. The challenge remains that enterprise adoption of quantum technologies is still nascent.

D-Wave Quantum (QBTS)

D-Wave Quantum disclosed Q1 2026 revenues of $2.9 million, representing a decline exceeding 80% year over year and falling short of analyst projections. Despite this, shares rallied as investors concentrated on forward-looking bookings.

Bookings soared to $33.4 million from $1.6 million in the previous year. This surge included a $20 million quantum computing system purchase by Florida Atlantic University and a $10 million two-year agreement with an unnamed Fortune 100 corporation.

D-Wave concluded the quarter with approximately $588.4 million in cash and marketable securities.

The company also completed its acquisition of Quantum Circuits to broaden its gate-model quantum computing capabilities, while maintaining its focus on annealing technology platforms.

Bottom Line

All three organizations continue operating at a loss within an immature market. Yet each presents a distinct investment angle on quantum computing exposure.

Quantum Computing Inc. demonstrates rapid revenue expansion. Rigetti delivers a hardware and systems narrative supported by government partnerships. D-Wave boasts the most impressive bookings momentum and the most established commercial client portfolio to date.

Investors tracking this sector should observe whether bookings materialize into actual revenue and whether any of these companies can approach profitability in upcoming quarters.
