The Kalshi promo code MLB offer turns a $25 trade into up to $500 in bonuses, and Tuesday’s White Sox-Cubs game on TBS gives new users a marquee market to start with. Enter code LABS at signup, verify your account, and put $25 to work on any MLB market to trigger the reward.
Kalshi credits the bonus the moment your qualifying volume hits $25, so you find out where you land before the final out. Most new traders get $15, while the upper tiers stretch to $75, $100, and a rare $500. Just remember that LABS is the code that unlocks it.
The Kalshi promo code MLB welcome offer, code LABS, reaches traders in 42 states plus Washington, D.C.: AK, AL, AR, CA, CO, CT, DC, DE, FL, GA, HI, IA, ID, IN, KS, KY, LA, ME, MN, MO, MS, NC, ND, NE, NH, NJ, NM, NY, OK, OR, PA, RI, SC, SD, TN, TX, UT, VA, VT, WI, WV and WY.
Kalshi operates as a federally regulated exchange, not a sportsbook, so you buy and sell event contracts against other traders. Prices sit between one cent and 99 cents, which means the market itself shows you the implied probability of each outcome in real time.
White Sox vs. Cubs Odds, Preview and Kalshi Predictions
The Cubs host the White Sox at Wrigley Field at 8:05 p.m. ET on TBS, headlining a full MLB slate. The North Siders enter as the market favorite in MLB odds across the board, though rivalry games historically compress the gap between these two clubs regardless of where each sits in the standings.
Check the MLB lineups roughly two hours before first pitch, since both managers rest regulars in August and a single scratch reshapes the run environment. The MLB weather report carries even more weight at Wrigley: a wind blowing out toward Waveland Avenue inflates totals, while an inbound breeze off the lake pushes them down. Kalshi prediction markets react to that forecast, so early positions often price better than late ones.
Bullpen usage over the previous three days matters here too. Both staffs leaned heavily on high-leverage arms this month, and a short bridge to the ninth changes how much a one-run lead actually means in the sixth.
White Sox vs. Cubs Prediction: Kevin Gausman 6+ Strikeouts (60%): Kevin Gausman draws a favorable strikeout matchup against a White Sox lineup with a 26.3% projected K rate, and his increased splitter usage has generated more whiffs. With Chicago struggling offensively since July 1, Gausman is in a strong spot to rebound and record 6+ strikeouts.
