Second round markets are already up at Polymarket at the time of writing. This is one of the best prediction market sites after all. Although there are fewer matches than the first round, the field is getting tougher and games are becoming even more exciting.
The table below shows how Dino Prizmic and Tommy Paul are priced ahead of their upcoming matchup, as well as the chances of winning based on market sentiment.
| Player | Implied win probability | Trading price |
|---|---|---|
| Dino Prizmic | 22% | $0.22 |
| Tommy Paul | 79% | $0.79 |
American Tommy Paul is the favorite with a 79% implied probability. His $0.79 price is how much it costs to buy a contract for him to win. Each winning contract pays $1, which means if the market settles with him as the winner, you’ll get a $0.21 profit. Dino Prizmic, on the other hand, has a lower trading price and will bring in a bigger profit, but the market suggests the young Croatian has lower chances of winning.
