Two-legged arbitrage — lock YES + NO below $1.00 and hold to resolution

PolymarketKalshiMatched order books between Polymarket and Kalshi

The bot buys the YES and NO legs on opposite venues whenever their combined cost drops below $1.00, then holds to resolution. Each resolved pair pays $1.00 per share regardless of outcome — there is no token to sell across venues, so profit is locked the moment both legs fill.
