IonQ agrees to buy Elisity in stock deal worth up to $1.3 billion
The proposed acquisition would pair quantum security tools with enterprise network access controls. Closing remains subject to approval.

IonQ said on October 12 that it has signed an agreement to buy cybersecurity company Elisity in a stock transaction valued at up to $1.3 billion. The announced deal has not closed. IonQ expects completion in the fourth quarter of 2026, subject to regulatory approval and other closing conditions.
The maximum value includes as much as $150 million tied to Elisity’s future business performance. That makes the headline figure an upper limit rather than a guaranteed payment.
What the companies want to combine
The proposed purchase would bring together IonQ’s post-quantum cryptography and quantum key distribution capabilities with Elisity’s enterprise network security software. Elisity’s tools use information about identities, devices and risk to restrict which systems can communicate across a network. The companies describe the combination as a way to strengthen current defenses while preparing for future quantum-related security risks.
Those benefits remain plans, rather than demonstrated results of the acquisition. The announcement does not mean that a new combined product is already available.
What happens next
In a separate October 12 statement, Elisity CEO James Winebrenner said the company intends to keep serving customers under its current leadership after closing. He said the proposed roadmap would connect cryptographic upgrades with its existing access-policy platform.
The next concrete milestone is completion of the transaction. Readers following the deal should distinguish the agreement announced today from a later announcement confirming that approvals and closing are complete.
