IonQ Stock Up 16% Since Q2 Earnings: Should You Buy or Book Profits?

IonQ IONQ has witnessed a notable rebound since its Aug. 5, 2026, second-quarter earnings release, with shares surging 15.9% since then, outperforming Rigetti Computing’s RGTI 12.1% gain and D-Wave Quantum’s QBTS 1% decline. Importantly, this momentum follows a massive July selloff that sharply reset valuations across pure-play quantum stocks, with IonQ among the hardest hit.

The post-earnings recovery reflects improving fundamental momentum. IonQ reported a strong revenue increase of 287% year over year, while remaining performance obligations reached $485 million. The company also raised its 2026 revenue outlook to $280-$290 million.

The completion of the SkyWater acquisition further strengthens its vertically integrated, U.S.-based manufacturing strategy and quantum roadmap. With quantum computing gaining strategic importance amid rising government and enterprise investment, investors should now thoroughly reassess IonQ’s execution, valuation and commercialization trajectory for potentially significant 2026 upside.

What Is Driving IonQ’s Stock Outperformance?

Stronger Fundamentals:  IonQ delivered 287% year-over-year revenue growth and 20% above the midpoint of its prior guidance. Growth was driven by global deployments of its Tempo systems, cloud utilization and broader commercial momentum. Importantly, 60% of revenues came from commercial customers, while international and multi-product revenues represented about 50% and 25%, respectively. RPO also climbed 297% year over year, supporting the company’s decision to raise 2026 revenue guidance to $280-$290 million. Management expects $135-$145 million of revenues in the second half and does not anticipate a sequential revenue decline, pointing to continued growth through year-end. The 2026 outlook also assumes more than 100% organic growth and excludes any contribution from the recently completed SkyWater acquisition, leaving potential upside if the integration and commercialization strategy progresses as planned.

Favorable Policy and Strategic Backdrop: The June 22 White House executive order explicitly called for accelerating the commercialization and deployment of quantum computing, sensing and networking, while also strengthening domestic quantum supply chains and manufacturing. This aligns closely with IonQ’s July 31 completion of its SkyWater acquisition, which creates a vertically integrated U.S. quantum platform. The second-quarter update also cited new defense and national-security initiatives with Anduril and Sandia National Laboratories, potentially expanding IonQ’s addressable government market.

What's Next for IonQ: Q3 and Full-Year 2026 Estimates

The Zacks Consensus Estimate for IONQ’s third-quarter and 2026 EPS is pegged at a loss of 26 cents and a loss of $1.19 per share, respectively, implying 92.74% and 34.6% improvements over year-ago reported figures.

IonQ's 50-Day and 200-Day Moving Averages

Technically, the chart shows IONQ is currently slightly above its 50-day SMA and above its 200-day SMA, indicating that the recent post-earnings rebound has pushed the stock back above both key trend indicators. The move above the 200-day SMA is notable after the July selloff and suggests that near-term momentum is improving. However, the narrow gap between the stock price and both moving averages indicates that the recovery is yet to establish a strong technical cushion.

Valuation Remains a Key Risk

The valuation remains demanding despite the recent pullback. IONQ is currently trading at 46.51x P/S versus 5.03x for the S&P 500, a roughly 9.2x premium. While below its three-year median of 67.48x, the premium leaves limited room for execution missteps.

Conclusion: Book Profit Now?

IonQ’s improving fundamentals and quantum-computing progress support its long-term prospects, but the near-term risk-reward profile appears less attractive following the recent rally. Also, limited cushion above its 50- and 200-day moving averages suggests that much of the near-term optimism may already be priced in. The stock carries a Zacks Rank #4 (Sell) and trades at 46.51x sales, significantly above the broader market. With shares already up 15.9% since the second-quarter release, investors may consider locking in gains while reassessing the stock after its strong recovery.
