OpenAI marketplace won't require its own inference, puzzling analysts

On October 1, analyst Matt Slotnick posted a tweet thread unpacking OpenAI's app marketplace announcement. His core finding: listing on the marketplace apparently does not require using OpenAI's own inference infrastructure—the participant list even includes an open-source model provider—and the marketplace takes only a small cut of transaction value.

Confirmed

Per the announcement, joining the OpenAI marketplace is not contingent on using its inference services, and an open-source model provider is among the listed participants.
The marketplace monetizes by taking a relatively small percentage commission on transactions.

Why it matters

Slotnick contrasts this with the hyperscaler marketplace model, where value comes mainly from co-selling customers onto your own infrastructure—customers running on another cloud can't even get marketplace listing or co-sell eligibility. By choosing not to use the store as an infrastructure-lock-in lever, OpenAI may be giving up the path of using the marketplace to force inference compute pull-through, instead keeping the ecosystem open with a low take rate—a strategic difference that will shape developer adoption and the platform's long-term monetization structure.
