Plurimarket

How Plurimarket Works

The first fully permissionless prediction market where anyone can create markets and AI resolves them — no gatekeepers, no intermediaries.

STEP 1

Anyone Can Deploy a Market

Plurimarket removes all barriers to market creation. Whether you want to bet on the outcome of an election, a sports game, a crypto milestone, or any verifiable event — you can create a market for it in seconds.

There are no approval processes, no review boards, and no waiting periods. Simply write a clear question, define a resolution prompt that tells the AI how to determine the outcome, set a resolution date, and your market goes live immediately.

Creating a market is simple:

  • 1Write a question — a clear, unambiguous question about a future event.
  • 2Define a resolution prompt — tell the AI exactly how to verify the outcome using publicly available information.
  • 3Set a resolution date — choose when the market should be resolved.
  • 4Go live — your market is instantly available for the world to trade on.
STEP 2

All Markets Are Settled With AI

Traditional prediction markets rely on centralized resolution committees or designated oracles to determine outcomes. This creates bottlenecks, introduces bias, and requires trust in third parties. Plurimarket eliminates all of this.

When a market reaches its resolution date, an AI model with real-time web search capabilities evaluates the outcome. It reads the resolution prompt defined by the market creator, searches for current information across the web, and delivers a deterministic YES or NO answer.

How AI resolution works:

Resolution triggers automatically — when the market's resolution date arrives, the process kicks off without human intervention.
AI searches the web in real time — the model uses OpenAI's GPT-5.2 with web search to find authoritative, up-to-date information about the event.
Outcome is delivered on-chain — the result is posted to the blockchain via Chainlink Functions, making it tamper-proof and publicly verifiable.
STEP 3

Transparent, Permissionless and Open Source

Every market on Plurimarket shows you exactly how it will be resolved — before you place a single trade. The resolution prompt that will be sent to the AI is clearly posted on every market page, so you can read the exact instructions the model will follow. The system prompt given to the OpenAI API call is also publicly visible, so you know precisely how the AI is configured to evaluate outcomes.

There are no hidden rules, no secret criteria, and no behind-the-scenes adjustments. What you see is what the AI sees. This level of transparency means you can evaluate the fairness and clarity of any market before you participate.

Plurimarket is built on smart contracts deployed on-chain. Every market, every trade, and every resolution is recorded on the blockchain — immutable and auditable by anyone. There is no company that can shut down a market, block a user, or change the rules after the fact.

The entire codebase — smart contracts, frontend, backend, and AI integration — is open source. Anyone can audit the code, verify the resolution logic, fork the project, or contribute improvements.
