OpenAI Acquires Ona To Expand Codex Agent Capabilities

TLDR

• OpenAI agreed to acquire cloud infrastructure startup Ona.
• Ona’s team will join OpenAI’s Codex division.
• Codex now has over five million weekly active users.
• The deal remains subject to customary closing conditions.
• OpenAI continues expanding through recent AI acquisitions.

OpenAI has agreed to acquire cloud infrastructure startup Ona as it expands support for autonomous AI agents. The deal will bring Ona’s team into OpenAI and strengthen the company’s Codex coding platform. OpenAI said the acquisition will help agents handle longer tasks and improve enterprise deployment capabilities.

Ona Technology Set To Strengthen Codex Platform

According to OpenAI, Ona provides secure and pre-configured cloud environments for AI agents. Those environments allow agents to access tools, systems, and operational context. OpenAI said the technology will help Codex complete longer-running assignments. The company also stated that organizations will gain better tools for deploying agents into production environments. Financial terms of the acquisition were not disclosed.

The transaction remains subject to customary closing conditions. Once completed, Ona employees will join OpenAI’s Codex team. OpenAI said the integration will support ongoing development of agent-based products. The company has increased investment in coding tools during recent months. Demand for AI-powered software development tools continues to grow across enterprise users.

Ona’s chief executive, Johannes Landgraf, commented on the acquisition in a LinkedIn post. Landgraf said the transaction represents an expansion of the company’s mission. “I always thought selling the company would feel like an ending,” he wrote. He added that the company’s work now feels larger and more important. His comments came shortly after OpenAI announced the agreement.

Competition In AI Coding Tools Continues To Intensify

OpenAI launched ChatGPT in 2022 and helped accelerate adoption of generative artificial intelligence tools. Since then, the company has expanded its focus beyond chatbots. Coding assistants have become a major area of development and investment. OpenAI has directed additional resources toward Codex as adoption increases. Software developers increasingly use AI agents within daily workflows.

Company figures show Codex now supports more than five million weekly active users. OpenAI reported three million weekly users in April. The latest figure represents continued growth for the platform. Meanwhile, rival Anthropic has gained traction through its Claude Code product. Anthropic does not publicly disclose usage figures for the service.

OpenAI and Anthropic are also moving toward public market listings. OpenAI confidentially submitted its prospectus to regulators on Monday. Anthropic filed its own confidential registration documents days earlier. Both companies continue competing across several AI product categories. Coding assistants remain one of the fastest-growing segments in the industry.

Acquisition Strategy Remains A Key Growth Focus

The Ona acquisition extends a series of recent purchases by OpenAI. In March, the company announced plans to acquire cybersecurity startup Promptfoo. Earlier in January, OpenAI acquired healthcare technology company Torch. Reports valued the Torch transaction at approximately $60 million. The company has steadily expanded through targeted acquisitions.

Before those deals, OpenAI announced the purchase of software applications in October. The startup developed an artificial intelligence interface called Sky for Apple Mac users. OpenAI also completed one of its largest acquisitions in May 2025. The company agreed to buy Jony Ive’s AI hardware startup io. Reports valued that transaction at more than $6 billion.

OpenAI continues to add technology and talent through acquisitions. The company said Ona’s infrastructure will support future Codex development. OpenAI expects the technology to improve agent performance across complex workflows. The acquisition also expands the company’s enterprise-focused capabilities. Closing conditions must be completed before the transaction becomes final.
