One event. Two venues. One number matters: the gap.

gap133 ranks the price difference between Polymarket and Kalshi on the same prediction markets. We cover the overlap: if it trades on both venues, it's on the board; if it doesn't yet, it's in the watch below. We rescan the board every few minutes. Data only, no trading, not financial advice.

Free tier: all 12 pairs on the board, delayed 10 minutes. The desk tier gets the board live, personal gap alerts, 90 days of history, and the API and MCP server.see the desk tier
