What happened: IonQ (IONQ) stock jumped more than 18% Monday, breaking to a six-month high as quantum stocks caught a fresh bid.
What’s behind the move: SkyWater stockholders on Friday approved IonQ’s planned acquisition of the pure-play semiconductor foundry, giving the quantum stock a fresh catalyst. The $1.8 billion deal would bring SkyWater’s US-based semiconductor manufacturing and advanced packaging capabilities inside IonQ, giving the company more control over a key part of its quantum supply chain. The transaction is still subject to regulatory approvals and is expected to close in the second or third quarter of 2026.
