As Real Madrid firm as favorites to keep Vinicius Junior, Polymarket and Kalshi promo code "DIMERS" unlocks $20 + up to $500 bonuses on the transfer market

Vinicius Junior’s future is one of the summer’s most heavily traded transfer questions, and both Polymarket and Kalshi have full markets live on where the Brazilian lands next. The prediction markets have moved decisively toward a Real Madrid stay: Polymarket prices Real Madrid at 78¢ to be his next club with Arsenal at 22¢, while Kalshi has Real Madrid at 76¢ against Arsenal at 24¢. Traders on both platforms can access sign-up bonuses using promo code DIMERS: new users who register on Polymarket and deposit $10 receive a $20 sign-up bonus, while new users who register on Kalshi and trade at least $25 on Kalshi's Predictions markets become eligible for a bonus credit of up to $500.

Vinicius Junior Next Club — Live Prediction Market Odds

Real Madrid have been the clear favorite across both platforms for weeks. On Polymarket, Real Madrid’s “Yes” side has firmed to 79¢ with the “No” at 24¢, implying roughly a 78% chance he stays at the Bernabéu. On Kalshi, Real Madrid sit at 76¢ with a 77% implied chance on the market page. Both platforms are in tight alignment, and both show Arsenal as the only credible alternative the market takes seriously.

The Arsenal position is the defining prop in this market. Despite being the second choice on both platforms, the Gunners have drifted hard—down 28% over the period on Polymarket, sliding to 22¢, with Kalshi easing them to 24¢. The Saudi Pro League route through Al-Hilal, once a live rumor, has collapsed to under 1¢ on Polymarket, and both Manchester clubs are priced as longshots barely registering on either board. Note that Kalshi lists Manchester United as its third option while Polymarket lists Manchester City and Al-Hilal—the outsider fields differ slightly between platforms, but the top two are identical.

For a primer on how prediction markets process transfer sagas, the Dimers guide covers the mechanics in detail.

The story the markets are telling is one of a transfer saga losing its heat. With Real Madrid firmly ahead on both Polymarket and Kalshi and every rival trending downward, the smart-money read is a stay rather than a switch. For traders, the interest now sits less in the outright—which is heavily skewed—and more in whether Arsenal’s fade has further to run or whether a late twist could reprice the market before it resolves.
