IonQ Stockholders Approve $1.8 Billion SkyWater Deal to Build US Quantum Foundry Stack
2 articles · Updated · The Quantum Insider · Jun 12
Summary
$1.8 billion in cash and stock won IonQ shareholder approval for its SkyWater Technology acquisition, leaving the quantum-semiconductor deal awaiting regulatory clearance.
IonQ said the purchase would create a vertically integrated platform by pairing its trapped-ion quantum hardware with SkyWater, the largest exclusively US-based pure-play semiconductor foundry.
That manufacturing push follows IonQ’s September 2025 acquisition of Oxford Ionics, whose electronic qubit control technology helped IonQ report 99.99% two-qubit gate fidelity in October 2025.
The strategy reflects a broader trapped-ion race in which companies are trying to preserve fidelity advantages while solving scaling and manufacturing bottlenecks needed for fault-tolerant quantum computing.

Will trapped ions' superior accuracy overcome slow qubit scaling to beat rivals in the race for fault-tolerant computing?
As US giants consolidate the market, can European innovators using microwave control successfully challenge their dominance?
IonQ Acquires SkyWater for $1.8B: Vertical Integration, Regulatory Delays, and the Future of U.S. Quantum Computing
Overview
The proposed acquisition of SkyWater Technology by IonQ is facing a complex regulatory process, highlighted by an extended review period from the Federal Trade Commission. This reflects a broader trend of increased regulatory scrutiny in critical technology sectors like quantum computing and semiconductors. The deal is structured as a two-step merger, where IonQ’s subsidiary will first merge with SkyWater, making it a wholly owned subsidiary, followed by a second merger step. The extended review and intricate merger structure underscore the significant hurdles the companies must overcome, emphasizing the growing importance of regulatory approval in major technology transactions.
