Kalshi Promo Code: $10 Bonus With Code INSIDER1 for Tonight’s MLB Slate
New Kalshi users who sign up with promo code INSIDER1 receive a $10 bonus in trading credits after completing the qualifying trade requirement — a straightforward way to get started on the only CFTC-regulated prediction market with a full MLB slate to trade tonight. The credit applies automatically once you’re verified and have placed qualifying trades, and it can be deployed on any eligible market, including tonight’s 15-game baseball card.
One of the sharpest matchups to watch tonight is Boston at Toronto, where Dylan Cease takes the mound for the Blue Jays. Cease has been outstanding this season, posting a 2.28 ERA with 184 strikeouts across 126.1 innings — numbers that make him one of the best values on the mound anywhere in baseball right now. Boston counters with Patrick Sandoval, who’s still building innings back at 1-0 with a 3.38 ERA over a small sample. On Kalshi, that gap in form shows up directly in the contract price for a Blue Jays win, giving new traders a clear real-world signal to weigh before committing their bonus credits.
Why Kalshi Trades Differently Than a Sportsbook Bet
Kalshi runs as a federally regulated exchange, not a bookmaker. You’re trading event contracts peer-to-peer against other users rather than betting against the house, and contract prices — from one cent to 99 cents — reflect the market’s live probability estimate for an outcome like a Blue Jays win. There’s no vig baked into the line the way there is at a traditional sportsbook, and because Kalshi also covers politics, economics, and entertainment outcomes alongside sports, the $10 bonus credit isn’t limited to baseball if you want to explore other markets.
How to Claim the INSIDER1 Bonus
Visit Kalshi.com or download the app on iOS or Android and start the registration process. You’ll be prompted to enter a promo code during sign-up — enter INSIDER1 at that step. Complete the identity verification process, which is a regulatory requirement under Kalshi’s CFTC designation and typically takes just a few minutes. Once verified, link a funding source — ACH bank transfer or debit card both work — make your first deposit, and place trades totaling the qualifying volume to trigger the $10 credit, which is applied to your account automatically.
Terms to Know Before You Sign Up
This offer is for new Kalshi users only, one per person and per household. The promo code must be entered during initial registration — it can’t be applied retroactively. Credits typically expire 30 days after being issued, so plan to use them promptly. Kalshi’s sports contracts are currently restricted in a handful of states — including Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, Nevada, and Ohio — due to ongoing litigation with state gaming regulators, though economic, political, and entertainment markets remain available everywhere.
Bottom Line
With Dylan Cease on the mound in Toronto and 14 more games rounding out tonight’s slate, the Kalshi promo code INSIDER1 gives new traders a low-cost way to start putting real-world sports outcomes to work on a fully regulated exchange.
