We built an AI data agent for the hardest problem in sports — your March Madness bracket

When we learned that the perfect March Madness bracket has never been filled out, we couldn't stop thinking about it. Not once. Not by the most obsessive fan, not by the sharpest analytics team, not by anyone in a verifiable way in the entire history of the tournament.

The perfect bracket has never been filled out. That fact got us thinking about what an AI data agent could actually do with it.

Turns out, there are 9.2 quintillion possible bracket combinations. The math is staggering. And yet every year, people approach it the same way: gut feelings, school loyalties, a podcast they half-listened to in the car. What could our AI data agent actually do with that problem? We needed to find out!

What we built

Delphina is the most trusted data agent for AI-native teams. With a focus on knowing your business and using the right knowledge and context, we help fast-growing tech companies and global enterprises turn complex data into clear, usable insights. And this week, we pointed our data agent at something a little different: we loaded 11 seasons of NCAA D1 basketball data into our platform, added live Polymarket prediction markets, and focused our agent on March Madness.

The result is your new personal sports analyst and a bracket tool that actually thinks. Not a prediction model you have to trust blindly. Not a ranking someone else made. An AI you can interrogate — in plain language, right now, for free — at delphina.ai/ncaa.

You can use it to build you a fully personalized, data-powered bracket in just a few minutes, or ask it anything you want to know about any team, player, trend, or current odds.

Try asking anything, such as:

• Which teams are this year's best Cinderella candidates, and why?
• Which #1 seeds are most vulnerable to an early upset this year?
• Which 11-seeds should I pick to beat a 6-seed — and what does history say?
• Duke's championship odds surged nearly 8 points in a month. What does the data say about their chances?
• Is Polymarket undervaluing any teams this tournament?

With Delphina, every answer is verified by a critic agent and the analysis behind every claim is visible if you want to see it. And you can push back, ask follow-ups, and actually disagree with it.

Why this, why now

We’re excited to show what the product actually does in a way that anyone could engage with, where the stakes feel real, even if those stakes are just bragging rights. March Madness is perfect for that. Everyone has an opinion. The selection questions are genuinely hard to answer well without data. And the tournament runs for three weeks, and we believe you’ll have more fun with Delphina on your team.

Try it

Our data includes the full Selection Sunday field, is updated daily, and Delphina will be live through the tournament — so whether you're picking your Final Four today or second-guessing your Elite Eight bets next week, Delphina will be there.

Don’t take our word for it. Try it yourself!
