Kalshi Promo Code LABS: Trade $10, Get a $10 Bonus for the First Round of March Madness

The First Round of the men’s NCAA Tournament is where March Madness really starts to feel massive: all-day windows, bracket pressure, and nonstop swings from one game to the next. The First Round takes place on Thursday, March 19 and Friday, March 20, immediately after the First Four in Dayton, Ohio.

If you want a regulated, event-based platform that fits the chaos of those two days, the Kalshi promo code LABS is an easy place to begin. Kalshi is a CFTC-regulated predictions market platform. New users can unlock a simple offer: Trade $10, Get a $10 Bonus. That setup works well for March Madness because it keeps the first step small while giving you extra room to explore additional college basketball markets as the tournament unfolds.

What You Get with Kalshi Promo Code LABS

The offer tied to Kalshi promo code LABS is simple:

• Trade $10
• Get a $10 Bonus

That low entry point makes the platform approachable for first-time users. You can make one $10 first trade, receive the bonus, and then use that extra value to explore more than one market during the busiest two days of the tournament.

The Kalshi referral code LABS is especially useful during the First Round because the schedule is so dense. Instead of centering everything into one matchup, you can spread your activity across multiple games and react as the bracket develops.

Why the First Round of March Madness Fits Kalshi Predictions

The First Round is made for prediction markets because it creates constant information swings. Teams travel to several first and second round sites, the game windows stack quickly, and every upset changes how fans think about the next slate.

That makes Kalshi a natural fit for fans who like tracking:

• late injury and availability updates
• seeding pressure and matchup styles
• pace changes and turnover trends
• how early upsets shift tournament expectations

Because Kalshi uses clearly defined event contracts, it offers a structured way to follow those shifts in real time. If you aren’t sure how prediction market prices work or want to check them compared to American odds, use our prediction markets calculator to make the sharpest trades.

How to Make the Most of Your $10 Bonus During March Madness

A smart approach is to use the bonus across multiple ideas instead of pushing everything into a one single market. The First Round changes quickly, and a spread out approach can help you stay engaged as the bracket evolves.

That matters even more during the March Madness First Round schedule because it isn’t one event. It’s a two-day wave of games, and the bonus gives you extra room to participate in that broader tournament environment.
