Kalshi referral code "DIMERS" optimizes $10 UFC 328 bonus for Mother's Day

Saturday, May 9th, 2026, brings an action-packed, all-day postseason slate, and Kalshi has extended its popular referral code, “DIMERS”, into May 2026—meaning the $10 Kalshi referral bonus is now officially available for the UFC 328: Chimaev vs. Strickland middleweight title fight and today's Champions League action.

This timely Kalshi promo code update drops at the perfect moment for sports forecasters looking to invest in today’s pivotal UFC and UCL matchups. Because Kalshi operates under the federal oversight of the Commodity Futures Trading Commission (CFTC) rather than functioning as a standard offshore sportsbook, residents in approved states can legally acquire shares in the outcomes of their favorite sporting events. Notably, this Kalshi bonus is highly popular in California, Oklahoma, and New York among local fight fans eager to back Chimaev or Strickland, as well as soccer fans nationwide tracking the afternoon clash between Arsenal and Atletico Madrid.

With massive championship battles taking place today, activating the Kalshi code delivers an excellent starting point for new traders.

How to Unlock Your $10 Kalshi Bonus with the UFC 328 Promo Code:

When applying DIMERS, this Kalshi code rewards first-time traders with a $10 bonus the moment they execute 10 initial event predictions (or allocate their first $10 in total volume) on the Kalshi exchange.

• Access the Kalshi platform by visiting their website or downloading the mobile application.
• Enter your Kalshi code (DIMERS) while completing the sign-up form.
• Pass the standard identity verification steps and fund your new trading wallet.
• Complete 10 event trades (or trade your first $10) to trigger your $10 Kalshi bonus.

Every single finalized contract counts toward your requirement, whether you are buying shares on Khamzat Chimaev to maintain his undefeated reign or taking a position on Sean Strickland to secure a massive championship upset.
