Cboe launches Cboe Predicts with S&P 500 “yes/no” close contracts
Interactive Brokers is live first, and Cboe expects Charles Schwab access in the coming months.
Start hereEvent contracts trade from $0 to $1, so the job is managing probability moves and execution, not just being right at settlement.

The edge is matching your thesis to each contract’s resolution rule and close time, not guessing “hawkish” or “dovish.”

Bots can earn by enforcing YES+NO parity and capturing spreads, but thin liquidity and operational risk cap sustainable returns.

A good Polymarket trade needs both a probability edge and an execution edge, because the displayed price can be a midpoint or a stale last trade.

True arbitrage only exists when contracts match on settlement, you can fill both legs at size, and fees still leave a net edge.
