Kalshi has announced a $10 million prize pool for the upcoming NCAA 'March Madness' tournament, following in the footsteps of Warren Buffett's famous challenge. The platform will award $1 billion to any user who perfectly predicts all game outcomes, a feat with odds of 1 in 120 billion. Additionally, Kalshi will grant $1 million to the participant with the highest prediction score and donate another $1 million to charitable organizations. The NCAA 'March Madness' tournament is set to begin tomorrow. Since 2014, Buffett has offered a similar $1 billion prize through Berkshire Hathaway, though no one has ever claimed it due to its difficulty. In 2018, Buffett adjusted the challenge, offering $1 million annually to anyone who correctly predicts all 16 tournament games.
