Win X March Madness Bracket Challenge, Get A Trip To Mars

March Madness just got a historic twist that is literally out of this world with the X Bracket Challenge.

The social media platform X, still commonly known as Twitter, is giving college basketball fans a once-in-a-lifetime opportunity: a trip to Mars on SpaceX’s Starship vehicle for the perfect bracket. The top participant will still walk away with $100,000 if no one achieves perfection.

Sponsored by Uber Eats, this NCAA Tournament bracket challenge will be hosted directly on X, making it easy to submit brackets, engage with fans, track live standings, and participate in fantasy games throughout March Madness.

The whole thing starts at 6 p.m. Eastern Sunday, and brackets must be submitted by 11 a.m. Eastern Thursday — just before the first round tips off.

How Does the X Bracket Challenge Work?

The X Bracket Challenge is not your typical March Madness contest that has become prevalent everywhere from office pools to sports betting sites.

It combines bracket predictions, fantasy games, and real-time leaderboards. Once brackets are locked in on March 20, participants can follow the action live as teams advance through the tournament.

Here are the prizes:

• Grand prize for a perfect bracket: A trip to Mars on SpaceX’s Starship. If the winner prefers an alternative:
  • $250,000
  • 1 year of free Starlink service
  • Astronaut training for a day
  • Sending a personal item to space on a Falcon 9 launch
  • VIP access to a Starship launch
• First runner-up prize: If no perfect brackets exist, the top participant will win $100,000.
• Fantasy game prizes: Four fantasy game winners will each receive $10,000.
• Bonus reward: All X users who submit a bracket will receive one free month of Starlink service (kit purchase required).

Why March Madness Is the Ultimate Sporting Event

The NCAA Tournament is one of the most exciting sporting events of the year, offering the potential for buzzer-beaters, Cinderella stories, and unforgettable moments. The single-elimination tournament features 68 teams vying for a national championship, with each game bringing intense drama and unpredictable outcomes.

March Madness starts with Selection Sunday, where the bracket is revealed. The First Four games occur Tuesday and Wednesday, followed by the first round on Thursday and Friday — a stage famous for massive upsets and shocking finishes. The tournament schedule continues with:

• Second round: March 22-23
• Sweet 16: March 27-28
• Elite Eight: March 29-30
• Final Four: April 5
• National championship game: April 7

Though millions of brackets get submitted every year, achieving a perfect bracket is nearly impossible — the odds are 1 in 9.2 quintillion. That’s why the X Bracket Challenge’s grand prize — a trip to Mars — matches the challenge’s nearly impossible nature.
