# Prediction Market Deep Dive

**Answers:** "What's happening in this specific market? Who holds it, who's trading it?"

Use `market_id` from the screener (`nansen-prediction-market` skill).

```bash
MID=<market_id>

nansen research pm ohlcv --market-id $MID --sort period_start:desc --limit 50
# → period_start, open, high, low, close, volume

nansen research pm orderbook --market-id $MID
# → bids[], asks[] with price and size

nansen research pm top-holders --market-id $MID --limit 20
# → address, side, position_size, avg_entry_price, current_price, unrealized_pnl_usd

nansen research pm position-detail --market-id $MID --limit 20
# → address, side, size, avg_entry_price, current_price, pnl

nansen research pm trades-by-market --market-id $MID --limit 20
# → timestamp, buyer, seller, taker_action, side, size, price, usdc_value

nansen research pm pnl-by-market --market-id $MID --limit 20
# → address, side_held, net_buy_cost_usd, unrealized_value_usd, total_pnl_usd
```

Notes:
- `--market-id` is a numeric ID from the screener, not a slug.
- Works with any market ID regardless of status (active or closed/resolved).
- All addresses are Polygon (EVM).
