Background: xAI and Kalshi

This announcement follows a previous partnership between Musk's xAI and prediction market platform Kalshi.

Musk's Belief in Prediction Markets

Musk has consistently championed prediction markets, particularly Polymarket, as superior to traditional polls for gauging public sentiment. He believes that the financial stakes involved in these markets lead to more accurate reflection of real-world expectations.

In October 2024, Musk tweeted: "Trump [is] now leading Kamala by 3% in betting markets. More accurate than polls, as actual money is on the line."

This belief was further emphasized during a Trump campaign rally.
