IonQ Inc. (NYSE:IONQ) has reached an agreement to acquire Elisity Inc., a provider of Zero Trust cybersecurity solutions, in an all-stock transaction valued at as much as $1.3 billion. The structure of the deal includes up to $150 million in performance-based earnouts and anticipates a closing in the fourth quarter of 2026, contingent on regulatory approval.
The transaction is intended to combine IonQ's hardware capabilities in post-quantum cryptography (PQC) and quantum key distribution (QKD) with Elisity's software-defined Zero Trust architecture and its IdentityGraph microsegmentation platform. Company statements framing the rationale for the acquisition reference recent White House directives that require federal agencies to migrate to quantum-resistant encryption, positioning the combined offering to defend enterprise and government networks from current high-speed network threats as well as potential future quantum-enabled decryption risks.
Elisity's commercial footprint includes more than 100 enterprise deployments. The company reports a history of doubling annual revenues while maintaining zero customer churn, and it serves a microsegmentation market that is estimated at over $10 billion. IonQ has stated that the acquisition should create cross-selling prospects across its existing customer base; the company noted that multiproduct revenue grew 40% year-over-year in the second quarter of 2026.
Under the terms announced, Elisity will operate as part of IonQ following the close of the deal and will retain its core leadership team, led by Chief Executive Officer James Winebrenner. Market reaction to the announcement included a roughly 2% decline in IonQ's shares during premarket trading on Monday.
