What to Trade on Polymarket Today — Wednesday, July 8
There's no World Cup action on Wednesday, so the day's live markets center on a three-game MLB slate and a WNBA doubleheader on USA Network. Your $50 bonus can be spread across any prediction market.
MLB on Polymarket (July 8)
| Matchup | First Pitch (ET) | TV | Home Win % | Away Win % |
|---|---|---|---|---|
| Yankees vs. Rays | 6:40 p.m. | Prime Video | 55% | 45% |
| Phillies vs. Reds | 7 p.m. | ESPN | 55% | 45% |
| Diamondbacks vs. Padres | 10 p.m. | ESPN | 56% | 44% |
The Yankees–Rays opener on Prime Video is the headline market of the evening, with the Phillies–Reds NL East matchup close behind. The late Diamondbacks–Padres window gives West Coast traders a nightcap to deploy any remaining bonus funds.
WNBA on Polymarket (July 8)
| Matchup | Tip-Off (ET) | TV | Home Win % | Away Win % |
|---|---|---|---|---|
| Lynx vs. Sun | 7:30 p.m. | USA Network | 29% | 71% |
| Fever vs. Sparks | 10 p.m. | USA Network | 30% | 70% |
The USA Network doubleheader is a clean way to put the Polymarket referral code ACTION bonus to work, from the Lynx–Sun opener to the primetime Fever–Sparks matchup.
Looking Ahead: World Cup Quarterfinals on Polymarket
Wednesday is a soccer off day, but the World Cup quarterfinals are next on the calendar after Tuesday's Round of 16, a good time to price in your tournament positions early rather than chasing them once the bracket sets.
Two ways to trade the World Cup on Polymarket right now:
- Match markets: once the quarterfinal fixtures lock, each game gets its own win/draw/win market. Getting in early, before public money moves the price, is often where the value sits.
- Tournament futures: the World Cup Winner market lets you hold a position on a country all the way to the final, and Polymarket's sell feature means you can cash out of a contract before the market resolves if the price moves your way. Current favorite: France 33%
You can hold your $50 bonus for the quarterfinals or split it between Wednesday's MLB/WNBA slate and a World Cup futures position; the funds are yours to allocate however you like.
