Bloomberg: Founders Fund discovered Polymarket CEO misused company funds before considering investment

October 20 – According to Bloomberg, in 2025, when Founders Fund was considering an investment in the prediction market startup Polymarket, it discovered that the company's CEO Shayne Coplan had used company funds to pay for private jet trips, personal apartment rent, and other personal expenses. At the time, Polymarket had not yet generated any revenue. People familiar with the matter said that before finalizing the investment, Founders Fund explicitly required Coplan to implement the company remediation measures then underway: improve financial controls and return the misused funds to the company.
