The Forbes billionaire list will be checked at 10:00 AM ET daily. UPDATE: On October 1, 2025, Forbes posted a story about Elon Musk having a net worth over 500 billion dollars. However, this market is determined by the 10am values of Forbes' The World's Real-Time Billionaires tracker. As noted at the end of the article, his net worth dropped to 499.1 billion later that day, and did not reach over 500 billion on the following day at 10am. Kalshi will continue to monitor the index at 10am for the strikes to resolve to YES.
