Upvote PM Line Check Share 1 / 3 ## About PM Line Check PM Line Check is a free tool that compares Polymarket odds against SX Bet in real time, letting traders see where prices diverge between the two venues. The interface lists markets across NBA, MLB, NHL, World Cup, EPL, UCL, UEL, Serie A, Ligue 1, and UFC, showing SX Bet and Polymarket prices side by side along with a calculated best payout. Odds can be viewed in American, decimal, or implied probability format, and users can set a bet size to see how payouts change accordingly. Markets can be sorted by start time, by best edge, or alphabetically, which makes it easier to scan for the widest pricing gaps at a glance. The tool is aimed at traders who want to catch mispriced lines before they close, using the price difference between Polymarket and SX Bet as a signal for better entry points or arbitrage. Data refreshes so users can check current spreads rather than working from stale odds, and there's a copy/share function to export a market snapshot as an image or post it directly to X. It functions as a lightweight cross-market monitor rather than a full trading platform, focused specifically on catching the moment before prices on one venue adjust to match the other.
