IonQ stock surges 517% as revenue leaps but losses widen

Quantum computing firm IonQ closed the second quarter of 2025 with revenue growth of 82 percent and a 52-week share price jump exceeding 500 percent, yet the company’s net loss deepened sharply compared with the prior year.

Revenue climbs while expenses accelerate

Founded in 2015 and headquartered in College Park, Maryland, IonQ sells cloud-based access to trapped-ion quantum computers through Amazon Web Services, Microsoft Azure and Google Cloud. The company reported second-quarter revenue of $20.7 million, beating analyst estimates by more than 20 percent and nearly doubling the $11.4 million recorded a year earlier.

Operating expenses rose to $181.3 million, pushing the operating loss to $160.6 million. Net loss widened to $177.5 million, or $0.70 per share, versus a loss of $37.6 million, or $0.18 per share, in the same period last year. Adjusted EBITDA came in at negative $36.5 million, and free cash flow stood at negative $90.99 million.

Cash position strengthened by equity raise

IonQ ended the quarter with $656.8 million in cash and equivalents, a 63 percent year-over-year increase. A $1 billion equity offering completed during the period boosted pro-forma cash reserves to approximately $1.6 billion.

The company filed its quarterly report with the U.S. Securities and Exchange Commission, outlining the larger deficit and ongoing investment in research, hardware development and talent acquisition.

Market performance outpaces benchmarks

IonQ shares have risen 16.49 percent over the past five trading days, 76.2 percent in six months and 517 percent in the last 12 months. By comparison, the Russell 2000 Index gained 4.6 percent in the latest week and 9.5 percent over the same annual period, underscoring the higher volatility and stronger upside displayed by the quantum computing specialist.

Analysts continue to weigh IonQ’s rapid top-line expansion against persistent losses and elevated operating costs. The firm’s sizable cash balance provides runway for further development, but profitability remains a central concern as the quantum computing market evolves.
