AMW Analysis
Codex is an enterprise-focused blockchain platform designed exclusively for stablecoins, providing dedicated and compliant infrastructure to minimize UX friction for enterprise use cases. Founded in 2021 and based in San Francisco, it has raised $15.8 million in seed funding from investors including Dragonfly Capital, Coinbase Ventures, and Circle Ventures.
Recent news flow, however, shows a different entity also named Codex—an OpenAI product receiving significant updates. In April 2026, OpenAI updated its Codex system with autonomous macOS control, memory, and new plugins to compete with Anthropic's Claude Code. Separately, OpenAI unveiled GPT‑Rosalind, a biology-tuned LLM available via Codex, and the infrastructure platform Temporal, which powers OpenAI's Codex, raised $300 million at a $5 billion valuation. These developments indicate that the name "Codex" is currently associated with two distinct companies: one focused on stablecoin blockchain infrastructure and another as an OpenAI development tool. The stablecoin-focused Codex has no tracked news of its own, while the OpenAI Codex is actively expanding its capabilities and infrastructure backing.
