Polymarket, the peer‑to‑peer prediction platform, is offering a limited‑time incentive for baseball fans. By entering the referral code ROCKY during sign‑up, newcomers receive a $20 credit that becomes active once they complete $10 worth of trades on the site.
The incentive coincides with Sunday Night Baseball, where the New York Yankees host the Philadelphia Phillies in a high‑stakes matchup. Odds currently list the Phillies as 65‑cent favorites and the Yankees as 36‑cent underdogs, reflecting a tightly contested game that draws considerable betting interest.
Claiming the ROCKY Bonus
To claim the bonus, users simply paste the ROCKY code at account creation, bypassing the standard waitlist, and then place at least $10 in trades. The $20 credit adds to a total of $30 of trading power, giving a tangible edge for early market participation.
What sets Polymarket apart is its dynamic contract system. Prices shift in real time as orders flow, as starting pitchers are announced and lineups are revealed, allowing the market to adjust instantly to new information.
The platform operates as a direct order book, matching buyers with sellers without an intermediary. This structure fuels rapid price discovery, especially on high‑profile events where global liquidity converges.
Polymarket shares the stage with Kalshi, another US‑regulated prediction marketplace that also runs sign‑up promotions. Both services let users wager on a wide range of markets, from sports outcomes to political events, while offering transparent, exchange‑listed contracts.
Beyond baseball, Polymarket provides access to markets for the PGA Tour, NFL futures, NBA games, UFC bouts and even political races. The breadth of options, combined with the ROCKY bonus, makes the platform attractive to both casual viewers and seasoned bettors.
