How Polymarket works for World Series Game 1
The Polymarket app is a predictions platform and financial exchange that is federally regulated by the Commodity Futures Trading Commission.
Because of Polymarket US’ status, it is available to users in more than 40 states, plus Washington D.C. Users also only need to be 18 or older to create an account.
Plus, Polymarket US has developed deals with MLB, MLS and NHL as the official predictions platform of those leagues. That makes the Polymarket app the place to predict the World Series.
Trading at a prediction market is different from betting at an online sportsbook. Polymarket US offers probabilities, not odds, and users purchase shares on outcomes as if they were buying stocks at an online exchange.
All trades are peer-to-peer and share prices are in line with the probability of each outcome playing out. But users can bid on shares at any price, and as long as a fellow Polymarket US user agrees to the terms, the transaction will go through.
The Polymarket app invites trading on props, including game and player props. But users can also create their own combo predictions, where they combine markets from multiple games and potentially on multiple sports.
For example, if you wanted to combine the World Series game with the Pistons game, you could click the “combos” tab on the top right of the page. Simply add your markets and your purchase price, and Polymarket US will find a way for you to complete the transaction.
Each successful share will pay out $1, so you can trade as if you were betting at a sportsbook. But the Polymarket app also invites day trading on outcomes, since all markets are live until they officially close.
For instance, if you were day trading on World Series Game 1, you might purchase shares on the Rays at $0.40 apiece then sell them for $0.55 apiece if Tampa Bay took the lead. From there, you could buy shares on the Brewers at $0.45 and sell those at $0.60 if they pulled ahead. The goal would be incremental growth while mitigating some of the risk.
