IonQ buys SkyWater for $1.8B to build vertically integrated quantum platform
What’s the deal? IonQ has agreed to acquire US chipmaker SkyWater Technology in a deal valuing the foundry at about $1.8 billion. The quantum computing company will pay $35 per share, split between $15 in cash and $20 in IonQ stock, with SkyWater becoming a wholly owned subsidiary.
The acquisition gives IonQ direct access to semiconductor manufacturing, combining its quantum hardware and software with SkyWater’s US-based foundry operations. IonQ has a market value above $16 billion and says the deal will create a vertically integrated quantum computing platform.
Why now? IonQ is moving as investor interest in quantum computing accelerates and the US government prioritises domestic chip manufacturing. The deal aligns with policy efforts to strengthen US supply chains and support technologies seen as critical to national security.
IonQ has also been on an acquisition spree, following its $1.08 billion purchase of UK-based Oxford Ionics in 2025. Owning manufacturing capacity could help it speed up development timelines and reduce costs as competition intensifies.
What could go wrong? The transaction is IonQ’s largest to date and adds operational complexity to a company still commercialising an early-stage technology. Integrating a capital-intensive foundry business could weigh on margins if demand does not scale as expected.
Quantum computing remains costly and largely limited to research use, with widespread commercial adoption still uncertain. The stock component of the deal is also subject to a collar, exposing both sides to share price swings.
The signal: The deal highlights a push towards vertical integration in quantum computing, mirroring earlier moves in the semiconductor industry. Companies are looking to control more of the stack to gain an edge in performance, cost, and supply security.
It also signals growing confidence that quantum computing is shifting from lab experiments to strategic infrastructure. With government backing and large acquisitions, the sector is starting to look less speculative and more industrial.
