Friday, August 14 brings a three-sport bonanza, and the Kalshi promo code SIBONUS lets you claim $20 bonus to trade on the action. You'll need to deposit at least $20 and complete $20 in trades to unlock your bonus. Check out other prediction market promos available today, but SIBONUS is your ticket to trading this stacked weekend opener.

How the Kalshi Promo Code Works for Friday's Three-Sport Slate

The Kalshi promo code SIBONUS delivers straightforward value: deposit $20, trade $20 worth of contracts, and Kalshi credits your account with a $20 bonus. You must be 18 or older and a new user to qualify. The code is required during registration, and you have seven days to complete your $20 in trades and seven days to use your bonus credit once awarded.

Friday's slate gives you plenty of trading targets. Three NFL preseason games kick off simultaneously: Dolphins-Commanders, Buccaneers-Jets, and Broncos-Falcons. You could trade on which backup quarterback impresses most or which team's special teams unit performs best. MLB offers Cardinals-Cubs at Wrigley, Yankees-Blue Jays in the evening, and Brewers-Dodgers as the night's marquee matchup. The WNBA features Wings-Fever, with Dallas visiting Indiana for a star-studded showdown.

Your bonus applies regardless of whether your trades settle as winners or losers. Say you trade $20 on the Dolphins-Commanders preseason game predicting Miami covers the spread. If that trade settles against you, you still unlock your $20 bonus. Alternatively, if you trade $20 on a Yankees-Blue Jays outcome and win, you keep those winnings plus your bonus credit, giving you extra capital to explore Kalshi's broader marketplace.

Key terms to remember: You must complete all $20 in trades within seven days of registration. Your bonus credit expires seven days after being awarded. Identity verification through KYC is required, including a government-issued ID and selfie. Kalshi accepts multiple payment methods including debit cards and PayPal for deposits.
