📊 Full opportunity report: The Skills Marketplace Nobody Is Building Yet on ThorstenMeyerAI.com — validation score, market gap, and execution plan.
TL;DR
A standardized skills marketplace for AI agents exists as a specification and reference implementations but has yet to be built into a functioning marketplace. This gap presents a strategic opportunity for future platform dominance.
The skills marketplace.
The directory exists. The marketplace doesn’t. Here’s the gap — and who closes it.
There are 140+ free Agent Skills on community marketplaces today. 17 official Anthropic skills under Apache 2.0. A published open standard at agentskills.io that OpenAI’s Codex CLI adopted. Microsoft, Google, Vercel publishing skill collections. And no skills equivalent of the App Store. No revenue share. No vetted-author verification. No security audit pipeline. No paid skills at all.
Folder. Frontmatter. Instructions.
A skill is a directory containing a SKILL.md file with YAML frontmatter and Markdown instructions, plus optional scripts and templates. Progressive disclosure: the agent loads only metadata into context until the skill becomes relevant. The format is simple. The implication is significant.

Five layers, in roughly the order they emerged. The first five are real and growing. The last five are the capture gaps — each is a real product, each is uncaptured, and any company that solves four of five wins the layer.

The platform owner’s incentives do not align with the developer’s.
Same structural problem that produced the App Store / Play Store / Steam separation in mobile and gaming. The platform owner extracts rent at the marketplace layer; the developer wants to publish once and distribute everywhere. The two only align if a third party owns the marketplace.
Skills as a platform retention feature.
- Cross-surface friction is a soft retention mechanism, not a bug
- Partner directory is curated to drive distribution into their stack
- Revenue share competes with the lab’s own enterprise sales motion
- Verified-publisher status is awkward when the auditor is also the model vendor
- Skills tied to one model = same problem the standard was built to solve
Three fronts the labs cannot credibly compete on.
- Cross-surface neutrality — “publish once, run on any model”
- Verified-publisher status as a paid security service
- 70/30 revenue share creates incentives for vertical specialists
- Trust calculation is cleaner: auditor ≠ model vendor
- Wins by being the only neutral broker between labs and enterprise

Smaller than you assumed. Closer than you think.
~20 engineers · $30–50M Series A · founded 2026 H2 / 2027 H1. Reference: Replicate’s positioning in model hosting — neutral, multi-vendor, developer-first. The challenge is distribution.
GitHub (= Microsoft, conflict). Cursor. Replit. Linear. The most legible path is “GitHub Skills” — but Microsoft competes at the model layer, reproducing the original problem.
Harvey in legal · a healthcare-AI company yet to emerge · Bloomberg in finance. Slower path, structurally stronger trust position. Customer never has to ask “is this skill safe?”

The 2026 H2 author looks like the 2007 YouTube creator.
Write the skills now. Capture when the marketplace ships.
The capture mechanism does not yet exist. Skills you write today have no way to charge for themselves. This is a feature, not a bug, for the next 12 months. Write skills, accumulate authorship reputation, build a portfolio that becomes legible the moment a marketplace with revenue share goes live.
The directory exists. The marketplace doesn’t. Whoever builds it captures the most defensible position in the post-model AI stack.
Four assignments. By role.
Start writing skills now.
The marketplace doesn’t exist yet but the reputation system runs on what you publish in 2026. The early-mover advantage when the marketplace ships is real. GitHub stars compound into discoverable authorship.
The window is open. Funding is favorable through Q3.
The standard is set, the demand is forming, the labs won’t build it themselves, and the second-mover penalty in marketplaces is severe. The “App Store of agents” thesis is investable today.
Demand a skill governance roadmap.
If your AI vendor’s answer is “we trust Anthropic to vet skills,” the answer is incomplete. Demand SIEM integration, audit logging, enterprise approval workflows. Current admin controls are a starting line.
The position is winnable in 2026 H2.
Natural fits: GitHub, Cursor, Replit. If you build developer tooling but aren’t one of those, you have 12 months to figure out whether your product becomes a skills publishing channel — or watches the value flow past it.
Why a Skills Marketplace Matters for AI Ecosystem Control
The absence of a formal marketplace for AI skills leaves a significant gap in the AI ecosystem. Building this layer could enable new revenue models, foster innovation, and establish platform dominance. Companies that develop a trusted, discoverable, and secure marketplace may position themselves as the core infrastructure providers in the post-model-commoditization era, where model interchangeability and organizational knowledge become key value drivers.Open Standards and the Fragmented Ecosystem of AI Skills
In late 2025, the AI community established an open standard for skills, enabling interoperability across multiple models and runtimes. Reference implementations from Anthropic and OpenAI demonstrated that skills are simple YAML artifacts, making them accessible to non-engineers and easy to deploy. However, despite these advances, no commercial marketplace has emerged. Existing discovery layers are community-driven and lack monetization or vetting, and the ecosystem remains fragmented with no centralized platform. The gap between the standard and a full marketplace reflects a strategic opportunity that smaller firms are positioned to exploit in the next 9 to 18 months.“The specification exists, but the marketplace layer does not. This is the gap that will define the next phase of AI infrastructure.”

Uncertainties Surrounding Marketplace Adoption and Security
It remains unclear which company or set of companies will successfully build and dominate this skills marketplace layer. The security, vetting, and trust mechanisms necessary for enterprise adoption are still in development, with no established standards or pipelines yet in place. Additionally, questions about monetization, discovery, and cross-surface portability are unresolved, and the timeline for a fully functional marketplace remains uncertain, estimated to take between 9 and 18 months.
Next Steps Toward Building a Functional Skills Marketplace
Key developments will include the emergence of platforms that integrate discovery, vetting, and monetization, possibly led by smaller firms or open-source communities. Major AI companies may begin piloting marketplace features, and industry standards could evolve to include security and compliance protocols. The next 12 months will determine which players can turn the open standard into a scalable, trusted marketplace that becomes the backbone of AI ecosystem monetization and distribution.
Key Questions
Why is there no marketplace yet for AI skills?
While open standards and reference implementations exist, a full marketplace layer with discovery, security, vetting, and monetization features has not been built. The ecosystem remains fragmented, and companies have yet to develop a trusted platform.
Who is best positioned to build the skills marketplace?
Smaller firms and open-source communities that can quickly develop and deploy the platform are currently in the best position. Larger AI companies may also enter once the standards and security protocols are established.
What benefits would a skills marketplace bring?
It would enable scalable discovery, secure transactions, and monetization of customer-specific, organizational, or procedural skills, creating new revenue streams and ecosystem control for platform providers.
When is a functional marketplace expected to launch?
Industry estimates suggest it could be within 9 to 18 months from May 2026, depending on the development of security, vetting, and discovery mechanisms.
