Markets

Connects ESPN schedules with Kalshi and Polymarket so you can see prediction market odds next to live games across NBA, NFL, MLB, and other major sports. The main use is checking if sportsbook lines diverge from market consensus or finding cross-platform arbitrage. It normalizes prices automatically (American odds, 0-1 probabilities, 0-100 integers) and pipes through edge calculation and Kelly sizing if you want a full bet evaluation. If you just need raw Polymarket data or pure odds math, use those skills directly. This is for when you want the context layer that ties game schedules to market prices in one dashboard.
