IonQ’s stock surged roughly 12% on September 8, 2026, after the quantum computing company lifted its full-year revenue forecast and held its first-ever joint Investor Day. The catalyst was straightforward: a major acquisition that adds manufacturing muscle and, critically, meaningful revenue to the books.
The company raised its 2026 revenue guidance to a range of $450 million to $460 million, incorporating contributions from SkyWater Technology, a semiconductor foundry IonQ acquired on July 31, 2026. With the deal closing in late July, SkyWater accounts for roughly five months of consolidated revenue in the updated figures.
What changed and why it matters
Before folding in SkyWater, IonQ’s standalone 2026 guidance already sat at $280 million to $290 million, itself a raise from earlier projections. The jump to $450–460 million reflects how transformative the SkyWater deal is to IonQ’s near-term revenue profile.
IonQ also reported that remaining performance obligations stood at $485 million at the end of Q2 2026. A backlog of that size signals customers are committing to future deliveries, which reduces the risk that current revenue growth is a one-time event.
Q2 results set the table
The Investor Day announcement came weeks after IonQ posted its Q2 2026 results, where the company recorded revenue of $80.1 million. That figure represents a 287% increase compared to the same quarter a year earlier.
Management used the Investor Day to introduce Superion, IonQ’s sixth-generation quantum computing platform. Chips for the Superion line are manufactured at SkyWater’s facility, which is precisely why the acquisition matters beyond its revenue contribution. The company now controls its own supply chain at a critical juncture in quantum hardware development.
Reading the market reaction
The stock began moving before the opening bell, gaining over 6% in premarket trading, with the full intraday move reaching approximately 12% by the time markets closed.
