OpenAI launches B2B marketplace with 32 partners

KEY FACTS

  • OpenAI launched its B2B marketplace on September 29, 2026, at DevDay, with an initial 32 partners.
  • Enterprise customers can apply their existing OpenAI committed spend to products inside the marketplace.
  • Baseten, as a partner, provides access to open-source models through Codex or the Responses API.
  • Enterprises can optimize agent workflows across open-source and closed-source models, routing each task to the best model.
  • OpenAI's current annualized revenue is about $70 billion, with enterprise business accounting for more than half.

PHYSIX OBSERVATION

OpenAI is shifting from a model provider to an AI application distribution platform, mimicking cloud vendors in becoming the enterprise software gateway. Allowing committed spend to buy Baseten's open-source models shows it values customer retention over token traffic. But the marketplace initially charges no listing fees and offers no co-selling, and open-source inference does not contribute to its own compute revenue, leaving long-term sustainability in doubt.
