# Margus

> Margus is a sports data and research site: schedules, standings, team pages and player stats for the NFL, NBA, MLB, NHL and soccer, with sportsbook and prediction market odds compared on one board and the best price highlighted on each side. It does not take bets or hold funds.

Sports fans who want stats and odds in one place, and adults 21+ who bet or trade where it is legal and want the best available price before they act. Free to browse. Margus may earn affiliate commission from some outbound links; that never changes how prices rank. Prices are observations stored by Margus, not live operator quotes: confirm every price with the book before betting. Contact: hello@margus.app.
