Quantum-computing firm IonQ (NYSE: IONQ) completed its acquisition of SkyWater Technology (formerly Nasdaq: SKYT) on Friday, July 31, 2026, closing a $1.8 billion cash-and-stock deal that had been pending since January and clearing final regulatory review three days earlier. The transaction gives IonQ direct ownership of the only United States-owned pure-play silicon foundry — an unusual vertical-integration move that puts a fabless quantum-hardware company in the semiconductor-manufacturing business.
The close punctuates a six-month regulatory and shareholder timeline. IonQ and SkyWater announced the tie-up on January 26, 2026, at a headline value the Wall Street Journal reported at $1.8 billion. Regulators gave the green light on July 28, and the deal closed on July 31.
Deal terms at a glance
SkyWater shareholders received a mixed consideration package at closing: $15.00 in cash plus 0.4883 shares of IonQ common stock for each SkyWater share tendered. The structure lets IonQ preserve some cash while giving legacy SkyWater holders continued equity exposure to the combined business.

Why a quantum firm bought a chip foundry
IonQ builds trapped-ion quantum computers — hardware that manipulates individual charged atoms with lasers. Trapped-ion systems have historically relied on external suppliers for the ion traps, control electronics, and photonic components that make the machines run. Owning a foundry outright is a structural break from that model.
In the closing statement, IonQ chief executive Niccolo de Masi described the rationale as end-to-end control of the manufacturing stack: “Secure chip design, fabrication, and packaging will deliver vertical integration across our full stack of quantum applications for land, sea, air, and space.” De Masi added that the combination “unlocks IonQ’s semiconductor-based approach to manufacturing new generations of quantum computers, while ensuring a fully scalable domestic supply chain.”
The domestic-supply-chain angle is not incidental. SkyWater, based in Bloomington, Minnesota, describes itself as the only U.S.-owned pure-play silicon foundry and holds Department of Defense Trusted Supplier accreditation, per its public company profile. Its fabs in Osceola, Florida and Austin, Texas (the latter acquired in June 2025) manufacture 90-nanometer and 130-nanometer chips on 200mm wafers — process nodes that are old by leading-edge logic standards but well-suited to specialized industrial, defense, and aerospace applications.
Part of a broader IonQ M&A campaign
The SkyWater deal is the largest in a rapid-fire acquisition spree IonQ has run since de Masi took over as CEO in August 2025. Public disclosures document a stream of transactions across quantum hardware, cryptography, satellite, and now semiconductor manufacturing:
Notable precedents in the run: Oxford Ionics in June 2025 for approximately $1.1 billion, adding another trapped-ion hardware team; Capella Space in July 2025 for roughly $311 million in stock, extending IonQ into satellite imagery and space-based quantum key distribution; and controlling stakes in ID Quantique and quantum-photonics firm Lightsynq. SkyWater is materially larger than any of them.
What the market has to digest
For IonQ shareholders, the acquisition materially changes the operating profile. Wikipedia’s summary of IonQ’s 2025 financials shows the pre-deal company at roughly $130 million in revenue against a net loss of $510.4 million. Absorbing a semiconductor foundry — a capital-intensive, gross-margin-thin business relative to software-heavy quantum services — will shift the company’s cost structure and add depreciation. Investors will look for management to lay out the pro-forma picture at the August 5 second-quarter earnings call and, in more depth, at the Sept. 8 investor day.
For the broader capital-markets story, the deal fits a wider pattern in 2026: strategic acquirers using stock as a currency to secure domestic-supplier positions in strategically sensitive industries, with regulators willing to clear even unusual combinations when a U.S.-domiciled critical-technology asset is at stake. That the Federal Trade Commission cleared a quantum-computing company’s takeover of a defense-accredited chip foundry in roughly six months is itself a data point on the current antitrust posture toward critical-technology tie-ups.
What to watch next
- August 5, 2026 — IonQ Q2 earnings call. First formal update as a combined entity; expect segment-level guidance on how SkyWater will be reported.
- September 8, 2026 — IonQ investor day. Company has flagged this as the venue for the multi-year integration and capacity roadmap.
- Post-close SkyWater bookings. SkyWater’s legacy customers include the U.S. Department of Defense and various industrial names. Whether those customers renew now that a quantum company owns the fab is a real integration risk to monitor.
