How the Kalshi Promo Code Offer Works
The Kalshi Promo Code offer is built for new users who want to try a CFTC-regulated prediction market rather than a traditional sportsbook. Sign up through the Bettors Insider link, enter INSIDER1 as your referral code when you create your account, and finish identity verification. The offer is limited to new Kalshi users, so anyone who already has an account will not qualify.
To earn the bonus, you need to deposit at least $10 and settle at least $25 worth of trades within 30 days of signing up. Once that threshold is met, $25 in trading credits is applied to your account automatically. Those credits cannot be withdrawn directly, but any profits you earn from trades made with them can be. The credits expire 7 days after they are issued, so plan to use them promptly and confirm the latest terms at Kalshi.com.
The offer is not available in Arizona, Illinois, Maryland, Michigan, Montana, New Jersey or Ohio, and the minimum age is 18 in most places and 21 in some states. For the full breakdown, see our Kalshi promo code page and our Kalshi review.
Sunday NFL Slate: Bengals in Madrid, Giants-Eagles and Bucs-Bears
Week 9 is the halfway point of the NFL season, and Sunday starts early. The Cincinnati Bengals (5-2) face the Atlanta Falcons (3-5) at Santiago Bernabeu Stadium in Madrid at 9:30 a.m. ET, the franchise’s third international game. At the time of writing, Cincinnati is a 3- to 3.5-point favorite with a total around 52.5.
Joe Burrow is the reason the Bengals are favored. He leads the NFL with a 73.0 completion percentage, 302.1 passing yards per game and 20 touchdown passes, and he has thrown 13 touchdown passes during a three-game winning streak. In Week 8 he threw for 462 yards and five touchdowns and added the game-winning touchdown run in overtime of a 43-36 win over Tennessee. He has thrown at least four touchdown passes in three straight games, and one more would tie him with Dan Marino, Tom Brady and Peyton Manning for four in a row.
Atlanta arrives on shaky footing. Michael Penix Jr. threw a career-high four interceptions in a 16-0 loss at Tampa Bay last week, and the Falcons defense has allowed 11 touchdown passes in eight games. Bijan Robinson gives Atlanta a ground-based path to staying in the game, leading the league with 704 rushing yards, but the matchup tilts toward Burrow and a Cincinnati offense that has been scoring at will.
The afternoon brings Giants at Eagles at 1:00 p.m. ET, where first-place New York is a 3.5-point favorite in Philadelphia, followed by Sunday Night Football, where the 6-2 Bears host the Buccaneers as 6.5-point favorites in a meeting of the NFL’s top two rushing offenses. Tampa Bay averages 168.6 rushing yards per game and Chicago averages 150.8. Lines can move before kickoff, so always check current numbers before you trade.
Why This Offer Stands Out
Most welcome offers for football fans come from sportsbooks, which makes this one a useful alternative. If you are weighing options, compare it against the DraftKings promo code offer, or read how prediction markets differ from sportsbooks before you sign up. New to the format? Our guide to how prediction markets work walks through the basics.
The Kalshi Promo Code INSIDER1 offer rewards a modest, achievable amount of trading activity with $25 in credits, and a full Sunday of football gives new users plenty of markets to explore. Check Kalshi’s own terms and your state’s eligibility before you deposit, and trade only what you can afford to lose.
