IonQ Falls 6% as $2B Equity Offering Follows $1.3B Elisity Stock Deal; D-Wave and Rigetti Retreat 4%

IonQ (NYSE:IONQ | IONQ Price Prediction) stock is trading at $32.76, down 6%, after the quantum company priced a $2 billion equity offering. Its raise arrives days after IonQ agreed to buy cybersecurity company Elisity in an all-stock deal worth up to $1.3 billion, so shareholders are absorbing two rounds of fresh equity in quick succession.

Meanwhile, D-Wave Quantum (NASDAQ:QBTS) stock is at $12.87, down 4%, as the selling spreads to other quantum names. As a sector gauge, the Defiance Quantum ETF (NASDAQ:QTUM) is down 2% to $145.22. For comparison, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.4%, with the broad market lower after an inflation reading came in above expectations.

IonQ’s back-to-back deals raise a question hanging over pure-play quantum names, including Rigetti Computing (NASDAQ:RGTI); Rigetti stock is declining 4% to $12.26 today. At issue is how much of their ownership existing holders give up to pay for growth. Speculative corners like this can still earn a place in a portfolio when they’re fenced off with real rules, which is the whole premise of our free speculation guide, here.

Heights Capital Deal Follows the Elisity Purchase

Under the offering terms, IonQ sold common stock and pre-funded warrants to an entity managed by Heights Capital Management at a price set above the prior session’s close, with J.P. Morgan as sole underwriter. The package also includes seven-year warrants to buy 100 million additional IonQ shares at an exercise level set well above what the Heights entity paid in the offering.

At its core, IonQ builds trapped-ion quantum computers, led by its IonQ Tempo systems, and sells access to them alongside networking, sensing and security products such as the ClavisXG Multiplex. Recent acquisitions of SkyWater Technology, which closed July 31, and Nexus Photonics brought chip fabrication and integrated photonics in-house.

Weighing the Bullish and Bearish Cases

The bullish case rests on operating momentum. IonQ reported Q2 2026 revenue of $80.05 million, up 286.8% from a year earlier, then lifted its 2026 outlook to a range of $280 million to $290 million. IonQ CEO Niccolo de Masi defended the long-horizon spending on the company’s August 5 earnings call: “Our capital strength also allows us to invest for the long term, which is essential, of course, in quantum, even as we execute quarter to quarter to quarter.”

Commercial commitments are growing too, with IonQ’s remaining performance obligations up 297% year over year. Separately, IonQ has signed memorandums of understanding with Anduril and Sandia National Laboratories on defense and national security work.

Dilution is the offset for IonQ. Its balance sheet is stronger for the new money, yet each existing share now represents a smaller claim on whatever the platform eventually earns. Adding to that pressure, the company’s stock-based compensation reached $141.8 million in Q2 2026.

D-Wave Faces the Same Funding Math

With its acquisition of Quantum Circuits in January, D-Wave added momentum to a gate-model program that sits alongside its annealing systems, giving it a dual-platform approach. D-Wave stock is down 51% year to date (YTD), a deep drop for a company still building out its commercial base.

Near-term results remain the weak spot, with D-Wave’s Q2 2026 revenue of $3.08 million missing estimates and holding essentially flat year over year. Demand signals look stronger, as the company’s first-half bookings surged to $35.5 million and commercial customers made up 62.4% of second-quarter revenue.

Share Count Race Defines IonQ’s Next Chapter

IonQ’s open question is whether commercial revenue scales fast enough to outrun a share count that has expanded with every deal. Management expects to begin commissioning 256-qubit systems in 2027, with those semiconductor-based machines set to become the main revenue driver.

Elisity adds a second test, since IonQ says customers increasingly discuss quantum computing and quantum security together. Success there would give the new shares more revenue to stand behind. Until then, shareholders may choose to size their positions for the possibility of further dilution.
