The GPT Store is OpenAI's public marketplace of custom GPTs created by users — discoverable, browseable, and (for top builders) monetizable. By 2026 it hosts 3M+ public GPTs across categories.

Launched in 2024, the GPT Store turned custom GPTs from personal toys into a marketplace. Builders define a system prompt + knowledge attachments + Actions + tools; the GPT lives at a discoverable URL with a usage page, ratings, and (for revenue-share-enrolled creators) monetization. Categories include writing, productivity, research, programming, lifestyle. Compared with app stores: discovery is weaker (Search is mostly text-based), trust signals are still maturing (verified builder, usage counts), monetization model is opaque (criteria + payouts not fully public). For B2C builders, the GPT Store is still the largest distribution channel for AI personas in 2026 — distribution beats deep tech for most launches.

## When to use

- Publishing personas to a broad consumer audience.

## Common mistakes

- Treating Store presence as marketing strategy — discovery is weaker than the App Store.
