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

Polymarket CLI (required for prediction market data)

brew tap Polymarket/polymarket-cli https://github.com/Polymarket/polymarket-cli
brew install polymarket
# or
curl -sSL https://raw.githubusercontent.com/Polymarket/polymarket-cli/main/install.sh | sh
polymarket --version

yfinance (optional — enables market proxy data)

pip install yfinance

  • CNN Fear & Greed Index — US market psychology; extreme readings affect EM risk appetite
  • Reddit Social Sentiment — r/investing, r/wallstreetbets, r/china, r/ChineseStocks, r/emergingmarkets
  • World Bank Macro — China GDP, CPI, export growth, FDI, US real interest rate

Scripts Usage

scripts/query-markets.py — Polymarket raw search

Returns active markets only by default. Use --all to include closed/resolved markets.

python3 scripts/query-markets.py "china"
python3 scripts/query-markets.py "taiwan" --limit 100 --format json
python3 scripts/query-markets.py "byd" --limit 50
python3 scripts/query-markets.py "pboc rate"
# Include resolved markets (for historical analysis only):
python3 scripts/query-markets.py "taiwan" --limit 100 --format json --all

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
# Closed markets (historical reference only):
python3 scripts/filter-markets.py --keywords taiwan --status closed --format json

scripts/fetch-market-data.py — Market proxy raw data

python3 scripts/fetch-market-data.py
python3 scripts/fetch-market-data.py --format json
python3 scripts/fetch-market-data.py --period 30d
python3 scripts/fetch-market-data.py --tickers "FXI KWEB ^VIX"

scripts/fetch-cn-news.py — China news raw headlines

python3 scripts/fetch-cn-news.py
python3 scripts/fetch-cn-news.py --format json --limit 20
python3 scripts/fetch-cn-news.py --source caixin --limit 30
python3 scripts/fetch-cn-news.py --source caixin,scmp

scripts/polymarket_analyzer.py — Full composite run

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)

  1. 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.
  2. Divergence Detection: The most profitable insights stem from discrepancies between explicit prediction market odds and implicit market proxy pricing.
  3. Probability Momentum: Focus on the delta (change over time). A contract moving from 10% to 30% in two days is highly actionable.
  4. Active Markets Only (Data Collection): Scripts default to active-only. Never treat a closed/resolved contract as a current signal.
  5. 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.
  6. 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.
  7. 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.
