Polymarket Promo Code TSN Unlocks $20 Sign-Up Bonus
| Polymarket Promo Code | TSN |
|---|---|
| New User Offer | $20 sign-up bonus |
| Terms and Conditions | 18+ and Present in the US |
| Bonus Last Verified On | August 14, 2026 |
Exclusively available for new Polymarket customers, this promotion grants a $20 sign-up bonus to help build an initial trading portfolio. To qualify, users must be 18+ and located in an eligible Polymarket state. The $20 bonus is automatically unlocked after the user has made an initial trade of at least $10, giving traders immediate access to extra funds.
Once that minimum trade clears and the bonus is activated, those funds can be applied directly to Friday's MLB slate. Whether traders want to take a position on Gerrit Cole, fresh off becoming the fastest pitcher in franchise history to reach 1,000 strikeouts as a Yankee, and the 68-win New York Yankees battling Shane Bieber's Toronto Blue Jays, or prefer the late showdown between the Milwaukee Brewers and Los Angeles Dodgers featuring starters Robert Gasser and Yoshinobu Yamamoto, the bonus can be utilized across any of Friday's exciting prediction markets.
Use Polymarket MLB Promo on Friday's Slate
| Matchup | Probability |
|---|---|
| MIL @ LAD | MIL 37% / LAD 64% |
| NYY @ TOR | NYY 59% / TOR 42% |
| BOS @ PIT | BOS 54% / PIT 47% |
When evaluating that marquee MIL @ LAD matchup, the Dodgers' steep market price is backed by a distinct offensive edge at home. Los Angeles sports a .260 batting average and a .766 OPS in their home ballpark, outpacing the Brewers' .251 average and .731 OPS on the road. However, Milwaukee, which possesses baseball's best overall record, presents intriguing underdog value on the mound. The Brewers' pitching staff has a 3.53 road ERA, which edges out the Dodgers' 3.71 mark at home. This dynamic is especially notable given recent frustrations surrounding Los Angeles' run support for starting pitchers like Yamamoto and late-inning bullpen unreliability.
