OpenAI's marketplace for custom GPTs — the largest agent distribution channel by user count, evolving toward agentic capabilities.
Why It Matters
The GPT Store (and its evolving Agent Store successor) has something no other agent marketplace can match: massive distribution. Millions of ChatGPT users can discover and use your agent without leaving the OpenAI ecosystem. Custom GPTs are evolving beyond simple prompt wrappers toward real agentic capabilities with tool use, code execution, and multi-step workflows. If reach matters more than flexibility, this is the channel to be on.
Strengths
- Largest user base of any agent marketplace by a wide margin
- Zero-friction discovery and usage for ChatGPT subscribers
- Evolving toward genuine agentic capabilities beyond simple GPT wrappers
- OpenAI's brand and distribution create immediate trust with end users
Limitations
- Locked into the OpenAI ecosystem — your agent only works in ChatGPT
- Limited customization compared to building on open frameworks
- Revenue sharing and monetization model is still maturing
- Quality control is inconsistent; the store is flooded with low-effort GPTs
Risks
- The store is a graveyard of abandoned GPTs — thousands of listings with no maintenance, broken tools, and stale data
- OpenAI can change the rules, deprecate features, or delist your GPT at any time with no recourse
- Revenue sharing has been underwhelming for most creators; the promised "GPT economy" hasn't materialized for anyone outside the top 0.1%
- Prompt injection attacks on custom GPTs are well-documented and OpenAI's mitigations are insufficient — users can extract system prompts
- Discovery is algorithmic and opaque; most custom GPTs get buried and never found
