A trader on the prediction market platform Polymarket has reportedly earned over $150,000 by accurately predicting Rick Rieder as the next Federal Reserve Chair nominee. The trader, identified as HD2, placed a $10,000 bet on January 15 when Rieder's chances were below 10%. As of January 25, Rieder's probability surged to nearly 60%, significantly increasing the value of HD2's position. The prediction market saw heightened activity as former President Trump made public comments about potential nominees, including Kevin Hassett and Kevin Warsh, causing fluctuations in their probabilities. However, Rieder, an executive at BlackRock, emerged as a strong contender following Trump's interview with him and subsequent media coverage. The total trading volume for the event exceeded $300 million, highlighting the market's intense interest in the nomination process.
