What each gauge means
- PMX-Volume — today's platform volume vs a recent average (~100 = typical).
- PMX-Whale — buy/sell tilt among large wallets (~100 = balanced).
- PMX-Sentiment — average implied probability across active books (a coarse mood proxy, not a forecast).
- Category heat — volume in each tagged vertical vs its own 30-day average. Tags match the Polydata screener: Politics, Sports, Crypto, Esports, Geopolitics, Economy, Weather, Culture, Commodities.
Tagged verticals vs full Polymarket nav
PMX category series follow Polydata's market_tags classification — the same nine used by the market screener. Polymarket's homepage tabs go wider (Iran, Tech, AI, Elections, …); those labels are useful for browsing books but are not separate PMX indices until they exist as stable tags in our index. For absolute platform size use State of Polymarket; for large individual fills use whales.
