About the company

IonQ sells quantum computing through cloud access and on-site systems that use trapped-ion qubits. Its processors, such as Forte and Tempo, are accessed by customers via cloud platforms or deployed on customer sites, and the company is expanding into quantum networking, quantum key distribution, and sensing through acquisitions and a SkyWater Technology deal. It differentiates itself with trapped-ion technology and by building a broader quantum ecosystem through strategic acquisitions and partnerships to connect devices and services beyond hardware alone. Its goal is to scale commercial quantum computing, grow revenue, and strengthen its cash position to support ongoing expansion and ecosystem development.

Simplify's Take

What believers are saying

  • NVIDIA selected IonQ’s Superion 256 for its Accelerated Quantum Research Center.
  • Florida International University ordered a Superion 256 system for late 2027 campus installation.
  • IonQ raised 2026 revenue guidance to $280 million-$290 million after record Q2 results.

What critics are saying

  • FTC warned July 31, 2026 SkyWater integration could foreclose rival foundry access.
  • Scott+Scott and Wolfpack Research targeted IonQ in 2026 over Pentagon contract disclosures.
  • Quantum commercialization still depends on 2027 deliveries; execution slip would crush the valuation premium.

What makes IonQ unique

  • IonQ’s trapped-ion systems posted 287% Q2 2026 revenue growth.
  • Superion 256 adds integrated electronic qubit control for 2027 customer deployments.
  • IonQ controls hardware, networking, and foundry capacity after SkyWater closing on July 31, 2026.

IonQ is the one quantum stock to buy with $1,000, despite $273M cash burn

A Motley Fool columnist says IonQ (NYSE: IONQ) is the one quantum computing stock he would buy with $1,000, though he calls it a speculative pick within a diversified portfolio. IonQ uses trapped-ion technology, in which ions hold their quantum states longer, cutting error rates. It is natively integrated with Google Cloud, Microsoft's Azure Quantum, and Amazon's Braket, and it has a deal with Nvidia to link its Superion 256 system with Nvidia's AI supercomputing rack. The finances are risky. Revenue rose 412% year on year in the first half of 2026, but free cash flow was negative $273 million. IonQ holds more than $2.1 billion in liquidity, about four years at the current burn rate, and trades at a price-to-sales ratio of 44.

IonQ's quarterly revenue hits $80M, nearing Innodata's $92.1M as AI data firm's growth slows

IONQ's quarterly revenue is close to overtaking Innodata's, as the quantum computing company grows far faster than the artificial intelligence data firm. IONQ earned $80.0 million in the quarter ended June 30, 2026, up from $12.4 million in the quarter ended September 30, 2024. Innodata took in $92.1 million, up from $52.2 million. Innodata's growth has slowed in 2026. Leadership changes in its chief executive officer and chief financial officer roles have also weighed on the stock, which is down about 35% over the past 12 months. IONQ has agreed to acquire an enterprise security infrastructure company in an all-stock deal valued at $1.3 billion. It also reached the final round of the Defense Advanced Research Projects Agency's Quantum Benchmarking Initiative on October 7.

IonQ shares fall 9% as it agrees $1.3B all-stock deal for Elisity

IonQ agreed to buy Elisity, a zero-trust security software maker, in an all-stock deal valued at up to $1.3 billion. The company's shares fell 9.07% to $36.27 on October 12, wiping about $1.44 billion off its market value. Quantum peers also slid. The price includes up to $150 million in earnouts tied to Elisity's performance. Closing is expected in the fourth quarter of 2026, pending regulatory approval. The share count depends on IonQ's 20-trading-day average price before closing, within a $33.07 to $49.61 collar. At the October 12 close, the deal equals about 35.8 million shares, roughly 9% on top of 397.30 million outstanding. IonQ said Elisity has doubled revenue and customers year over year, with more than 100 deployments, but gave no revenue figure.
