The Five Marketplaces That Distribute AI Agents in 2026
The agentic AI ecosystem in May 2026 is organised around five major marketplaces and one open standard. The AI agents market itself reached $12.06 billion in 2026 and is projected to grow to $53.2 billion by 2030 (~45 percent CAGR). This page maps the marketplaces, their hosted agent counts, and where the open Agent Skills standard fits.
Marketplace Comparison (May 2026)
| Marketplace | Owner | Catalog Size | Headline Product |
|---|---|---|---|
| Microsoft Marketplace | Microsoft | 11,000+ AI models, 4,000+ AI apps and agents | Unified Azure + AppSource; Copilot Agents Hub |
| Salesforce Marketplace (merged) | Salesforce | 10,000+ AppExchange apps; 2,600+ Slack apps; 1,000+ Agentforce agents | Agentforce 360 with Claude + GPT-5 integration |
| Google Gemini Enterprise | Folded former Agentspace into Gemini Enterprise | Agent creation, orchestration, discovery as one platform | |
| ChatGPT Workspace Agents | OpenAI | Team-built, share-then-refine model; not a public catalog | Per-team agents with persistent memory |
| Agent Skills Directory (open standard) | Anthropic + OpenAI joint standard | 1.2 million+ skills compatible with Claude Code, Codex CLI, ChatGPT | Open spec released December 2025 |
Six Things the Marketplace Landscape Tells You
- Salesforce has the broadest enterprise distribution. Combined Agentforce + AppExchange + Slack marketplace makes Salesforce the de facto distribution channel for enterprise AI agents. Anthropic Claude and OpenAI GPT-5 are both integrated as Agentforce 360 model options, making Salesforce one of the few cross-LLM platforms by default.
- Microsoft has the largest model catalog. 11,000+ models in the unified Marketplace, dwarfing any single competitor. The breadth reflects both Azure's model-hosting business and Microsoft's acquisition / partnership posture (Mistral, MosaicML, OpenAI, others).
- Agent Skills is the rare cross-vendor open standard. Anthropic released the Agent Skills spec in December 2025 and OpenAI adopted it for Codex CLI and ChatGPT shortly after. With 1.2 million+ skills now available, this is the largest open agent-extension ecosystem and works across Claude, ChatGPT, and OpenAI-derived products.
- Google merged Agentspace into Gemini Enterprise. The standalone agent marketplace approach was deprecated in favour of bundling agent creation into the main Gemini Enterprise product. This is a different model from Microsoft and Salesforce, which both maintain dedicated marketplace surfaces.
- ChatGPT Workspace Agents are not a public marketplace. OpenAI's approach is per-team-build-and-share rather than catalog distribution. This works well for internal-only agents but limits cross-organisation discovery, which is where Salesforce and Microsoft win.
- The 44.9 percent CAGR is the structural signal. Forecasts of $53.2B by 2030 imply ecosystem-wide investment growth that outpaces almost any other software category. Marketplaces compete on developer experience, model neutrality, and revenue share; the market is large enough to support multiple winners.
What This Means for AI Visibility
Each marketplace becomes a brand-discovery surface for the agents distributed through it. When an agent on Microsoft Marketplace looks for a payment processor or a CRM integration, the candidate set comes partly from the agent's training data and partly from the marketplace's own integration catalog. Brands with strong marketplace listings (deep integration metadata, recent activity, positive reviews) surface disproportionately in agent recommendations. Brands that ignore marketplace listings cede a significant slice of agent-mediated discovery to competitors. Treat marketplace listings as a first-order AI visibility investment for any brand that sells into agent-mediated channels.
Methodology
Marketplace data aggregated May 14, 2026 from Salesforce's 2026 AI agent trends, James Fahey's agent marketplace analysis, vendor announcements, and the Agent Skills directory. Catalog sizes are vendor-reported and not independently audited. Refreshed quarterly.
How Presenc AI Helps
Presenc AI tracks brand mentions and presence across agent-mediated discovery surfaces, including the major marketplaces above. When a brand's discoverability differs across marketplaces (strong on Salesforce Agentforce, weak on Microsoft Marketplace), the gap usually signals either an integration depth or a listing-completeness issue. Marketplace listing health is now a structural input to total AI visibility.
