| description | Analyze Polymarket prediction market data to provide investment insights for Chinese concept stocks (中概股) and A-shares. This skill should be used when the user asks about Polymarket data, prediction markets, A-share (A股) investment advice based on prediction market sentiment, or 中概股 correlations. |
Polymarket + Multi-Source China Market Sentiment Analyzer
Collect data from multiple information channels to support comprehensive sentiment analysis for Chinese concept stocks (中概股) and A-shares.
The agent performs all judgment and interpretation. The scripts in this skill are pure data collectors — they fetch raw information without making directional calls.
When to Use
- The user asks about Polymarket prediction market data for China/HK topics
- The user wants sentiment context for A-share or 中概股 investment decisions
- The user requests multi-source market intelligence (news, macro, market proxies)
- The user asks about specific stocks: BYD, NIO, Alibaba, Tencent, SMIC, etc.
Prerequisites

brew tap Polymarket/polymarket-cli https://github.com/Polymarket/polymarket-cli
brew install polymarket
curl -sSL https://raw.githubusercontent.com/Polymarket/polymarket-cli/main/install.sh | sh
polymarket --version
yfinance (optional — enables market proxy data)
pip install yfinance

scripts/filter-markets.py — Polymarket multi-filter
Defaults to --status active. Use --status closed or --status all to override.
python3 scripts/filter-markets.py --keywords taiwan,invasion --volume 100000
python3 scripts/filter-markets.py --keywords byd,nio,xpeng,alibaba,tencent
python3 scripts/filter-markets.py --status active --volume 50000 --format json

Executes all seven channels and prints a structured report:
python3 scripts/polymarket_analyzer.py
Channels unavailable at runtime degrade gracefully with no crash.
Analysis Workflows & Scenarios
Three scenario-specific workflows are defined in references/workflows/. Each workflow applies First Principles Thinking — defining a hypothesis first, then fetching only the data needed to test it.
| Scenario | File | Use When |
|---|
| 1. Macro & Geopolitical Risk (Top-Down) | references/workflows/scenario-1-macro-geopolitical.md | Taiwan, tariffs, PBOC, elections, USD/CNY stress |
| 2. Sector-Specific Catalyst (Bottom-Up) | references/workflows/scenario-2-sector-catalyst.md | EVs, Semiconductors, Property, Internet, specific companies |
| 3. Daily Market Pulse / Fast Digest | references/workflows/scenario-3-daily-pulse.md | Pre-market briefing, end-of-day delta check |
Core Analytical Principles (applied in all scenarios)
- Liquidity Weighting: Polymarket odds mean nothing without volume. Verify pool size. A 90% probability with $500 volume is noise; with $5M volume, it's a signal.
- Divergence Detection: The most profitable insights stem from discrepancies between explicit prediction market odds and implicit market proxy pricing.
- Probability Momentum: Focus on the delta (change over time). A contract moving from 10% to 30% in two days is highly actionable.
- Active Markets Only (Data Collection): Scripts default to active-only. Never treat a closed/resolved contract as a current signal.
- Historical Context (Mandatory): Always compare the current PM probability against: (a) the trend of the last 7–30 days for this specific contract, and (b) how analogous resolved contracts priced and resolved historically. A probability without a trend is not a signal — it is a datapoint. Use
--all to retrieve resolved contracts for comparison.
- Conflict-First Analysis: When any two sources disagree, the conflict itself is the most important finding in the report. Explain the conflict and its likely cause before forming any directional thesis. A thesis built by ignoring a conflict is not a thesis — it is wishful reasoning.
- Multi-Source Minimum: A directional conclusion requires ≥2 independent channels in agreement. Single-source signals must be labeled "Unconfirmed — Watch Only." State explicitly which channels confirm and which dissent.
Accumulated Experience
Before running any analysis, check EXPERIENCE.md for relevant prior observations:
- Source reliability notes calibrated from past sessions
- Known false signal patterns (e.g., sectors where PM historically misprices)
- Conflict resolution examples from past analyses
- User feedback on conviction thresholds
After the user provides feedback on analysis quality or outcome accuracy, append a new entry to EXPERIENCE.md using the format defined in that file.
Standardized Output Templates
Two templates are defined in references/templates/. Always use the appropriate template when generating a response.
| Template | File | Use When |
|---|
| A: Comprehensive Investment Insight Report | references/templates/comprehensive-insight-report.md | Full analysis from Scenario 1 or 2; includes confidence score, proxy confirmation table, source attribution, and data provenance |
| B: Quick Brief | references/templates/quick-brief.md | Daily pulse (Scenario 3) or when user needs a rapid digest; ALERT / WATCH / No-Change triage format |

Troubleshooting
Polymarket CLI not found
export PATH="$PATH:$HOME/.cargo/bin:$HOME/.local/bin"
yfinance not installed — fetch-market-data.py will print an error and exit cleanly; all other channels still work.
Chinese news sources unreachable — Some domestic RSS feeds block non-CN IPs. Use a HK/mainland proxy, or focus on: caixin, reuters_china, scmp, xinhua_en.
