## What it does

The skill breaks a request into its parts: event, venue, contract, settlement rule, deadline, related assets and the output you want. Then it picks one of three workflows and opens only that one — an event-probability brief, a cross-venue arbitrage check, or a comparison of market odds against options-implied and asset-implied pricing.

Market data comes from LLMQuant Data: contracts, odds, order-book depth, volume, fees, close dates, plus news, macro releases and related asset prices. Reports keep contract timestamps, settlement criteria, liquidity and market windows. If market data or settlement rules are missing, the skill will not infer fair probability or call something arbitrage — that is your cue to check what the conclusion actually rests on. Odds you type in yourself get labelled as user supplied.

Install runs through `npx skills add`, and the skill file lands at `~/.claude/skills/llmquant-prediction-markets/SKILL.md`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-prediction-markets -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/llmquant-prediction-markets/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/llmquant-prediction-markets/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-prediction-markets -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/llmquant-prediction-markets/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-prediction-markets -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/llmquant-prediction-markets/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install LLMQuant/skills llmquant-prediction-markets
```

2. **Manually: put the files in place**
- File: `.github/skills/llmquant-prediction-markets/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-prediction-markets -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/LLMQuant/skills --path skills/llmquant-prediction-markets
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/llmquant-prediction-markets/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-prediction-markets -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/LLMQuant/skills/tree/HEAD/skills/llmquant-prediction-markets/SKILL.md

## When to use it
- build an event-probability brief from market odds
- check arbitrage across venues and contracts
- compare prediction-market odds with options-implied pricing
- pin down settlement criteria and the contract deadline
- separate user-supplied odds from market data

## Example prompts
- Estimate the probability of this event from the contracts on that venue and write a brief
- Check whether there is arbitrage between the two venues on this event
- Compare the prediction-market odds with what the options are pricing in

# LLMQuant Prediction Markets

This category routes event-probability workflows for prediction markets, options-implied probabilities, and tradable event risk.

## Routing Rules

1. Identify the event, venue, contract, settlement rule, deadline, related assets, and requested output.
2. Select the closest workflow below.
3. Open only that workflow and any referenced local resources.
4. Use LLMQuant Data for prediction-market contracts, prices, liquidity, options, macro, news, and related asset prices.
5. Report contract timestamps, settlement criteria, liquidity, fees, market windows, and missing inputs.

## Workflow Index

| User intent | Workflow |
|---|---|
| Produce an event probability research brief from market odds and evidence. | [`workflows/event-probability-brief.md`](workflows/event-probability-brief.md) |
| Check prediction-market cross-venue or contract-level arbitrage conditions. | [`workflows/prediction-market-arb-watch.md`](workflows/prediction-market-arb-watch.md) |
| Compare prediction-market odds with options-implied or asset-implied event pricing. | [`workflows/probability-vs-options-pricing.md`](workflows/probability-vs-options-pricing.md) |

## LLMQuant Data Contract

Prefer LLMQuant Data when available. The workflows may need these data capabilities:
- Retrieve event contracts, settlement criteria, market odds, order-book depth, volume, fees, and close dates.
- Retrieve related news, macro releases, asset prices, and issuer or sector context.
- Retrieve options-implied probabilities, volatility, skew, and event-window pricing when available.
- Compare venues, contracts, and outcome sets while preserving timestamp and settlement-rule differences.

Fallback:
- If market data or settlement rules are unavailable, do not infer arbitrage or fair probability.
- If only user-provided odds are available, label the evidence as user supplied.
