Founders Fund Made Polymarket CEO Coplan Repay Expenses; ICE Joins Push for COO: Report

Backers of Polymarket have pressed founder and CEO Shayne Coplan to tighten the company’s finances and hand off more of its day-to-day management, Bloomberg reported on Tuesday, citing people familiar with the matter. The report lands as the prediction market raises new money while trailing rival Kalshi in trading volume. According to people familiar with the negotiations, Founders Fund , the venture firm cofounded by Peter Thiel, learned during its 2025 due diligence that Coplan had charged private jet trips, his apartment rent and other personal costs to the company, at a time when Polymarket had no revenue.
