OpenAI’s Ona deal gives Codex secure cloud runtimes for longer agent work

Codex is moving from short interactive coding help toward longer-running work that needs a trusted place to execute. OpenAI said on June 11, 2026, that it has reached an agreement to acquire Ona, a company focused on secure cloud execution and orchestration. The timing matters because OpenAI says more than 5 million people now use Codex each week, a 400% increase from earlier this year.

We’ve reached an agreement to acquire @ona_hq. Its secure cloud execution technology will help Codex take on longer-running work, even when laptops are closed, and help more organizations deploy agents securely in production. After closing, Ona will join OpenAI’s Codex team.

The substantive signal came from the OpenAI Newsroom account. The source tweet frames Ona as infrastructure for Codex agents that can continue after the user’s local machine is no longer active. The linked OpenAI post adds that Ona has helped 2 million developers work in secure, reproducible cloud environments, which is directly relevant to agent workflows that may run for hours or days.

The technical question is no longer only whether a model can write code. For production agents, companies need control over where the agent runs, which systems and credentials it can access, how activity is logged, and where review gates sit. OpenAI says Ona’s customer-controlled execution model will let agents operate inside an organization’s own cloud environment while OpenAI supplies the intelligence and orchestration behind the experience.

That positions Codex as a broader enterprise workflow system rather than a tool tied to one device or one active chat session. The OpenAI post points to sustained work across the software lifecycle: running tests, resolving issues, modernizing applications, addressing vulnerabilities, and supporting complex workflows over time. Those examples make the deal more concrete than a generic platform expansion.

The next item to watch is closing. OpenAI says the transaction remains subject to customary closing conditions, including required regulatory approvals, and that OpenAI and Ona will remain separate and independent until then. After closing, the Ona team is expected to join Codex; the real test will be whether persistent, customer-controlled runtimes become a visible part of how organizations deploy Codex agents in production.
