IonQ Q2 2025 earnings: revenue grows to $20.7M as losses widen and cash pile swells

August 6, 2025 · Published August 7, 2026

IonQ's quantum-computing revenue kept climbing in Q2 2025, but losses widened; the company raised full-year guidance and boosted cash after a $1B capital raise and acquisition spree.

Figures as reported by the company to the SEC for the quarter ended June 30, 2025. Analyst estimates are not part of a filing, so no comparison to expectations is shown.

Key takeaways

• Quarterly revenue came in at $20.7 million, continuing a rapid growth trajectory for the quantum-computing company as more customers use its hardware and cloud-based quantum computing services.
• The company posted a net loss of $177.5 million for the quarter, reflecting heavy ongoing spending on R&D, building out quantum hardware, and integrating several recently acquired companies — costs that are still far larger than the revenue IonQ is currently generating.
• Over the trailing 12 months, gross margin was about 36%, meaning IonQ keeps roughly a third of each revenue dollar after covering the direct cost of delivering its systems and services — before R&D, sales, and administrative expenses are subtracted.
• Operating margin over the same 12 months was deeply negative, underscoring that day-to-day operating costs still vastly exceed revenue — a common pattern for an early-stage hardware company that is scaling up production and research spending faster than sales.
• Net and pretax margin over the trailing 12 months appear positive, but that mainly reflects non-operating, non-cash items such as swings in the value of financial instruments tied to the company’s capital raises, rather than the underlying business turning profitable.
• Cash, cash equivalents and investments stood at $656.8 million at quarter-end, rising to roughly $1.6 billion on a pro-forma basis after a $1.0 billion equity investment closed shortly after the quarter closed — giving IonQ a large cash cushion to fund growth and acquisitions.
• IonQ raised its full-year 2025 revenue outlook to a range of $82 million to $100 million and guided to $25 million to $29 million for the third quarter.
• The quarter capped an active period of dealmaking: IonQ closed its acquisition of quantum-networking startup Lightsynq, closed its purchase of space-based quantum-key-distribution company Capella, and announced a proposed $1.075 billion acquisition of UK-based Oxford Ionics, moves aimed at building out both its quantum computing and quantum networking roadmap.
• The company also expanded internationally, signing memorandums of understanding with Japan’s AIST and GQAT, being selected by South Korea’s KISTI, and signing a $22 million deal with Tennessee utility EPB to build what it describes as the first U.S. commercial quantum computing hub.
• CEO Niccolo de Masi said the company “strengthened our balance sheet via the largest equity investment from a single institution in the quantum industry,” and said the closed Lightsynq deal and proposed Oxford Ionics acquisition together create what IonQ calls the most advanced quantum computing and networking roadmap in the industry.

Q2 2025 in context

Figures for the quarter ended Jun 2025 and the quarter ended Jun 2024, as reported to the SEC.

How the stock took it

IONQ Inc closed at $42.02 on Aug 5, 2025, the last session before the report, and at $40.49 on Aug 7, 2025, the first session after it — -3.6% across the report.

Closes from the market's daily record. Each figure spans the report date — from the last session that closed before it to the first that closed after — because a company may report before the open or after the close.
