World Cup Preview
For those ready to put their $50 sign-up bonus to use, the current Round of 16 slate features several compelling international showdowns. When navigating soccer prediction markets, keep in mind that standard match-winner markets ask you to predict the outcome at the end of regular time (90 minutes plus stoppage time). This means a draw is a distinct possible outcome alongside a win for either side.
The table below breaks down the implied win probabilities for the upcoming fixtures based on current prediction market shares.
| Matchup (Home vs Away) | Home Win % | Draw % | Away Win % |
|---|---|---|---|
| Brazil vs Norway | 55% | 27% | 20% |
| Mexico vs England | 31% | 31% | 40% |
