Polymarket said Tuesday it secured an investment from venture capital firm 1789 Capital and added Donald Trump Jr. to its advisory board, according to CNBC. Though the company did not disclose the terms, a source told Reuters that 1789 Capital’s investment in Polymarket was worth double-digit millions. The prediction market platform has surged in popularity, processing $6 billion in trades in the first half of 2025, driven by interest in event derivatives on politics, economics, and global affairs. Trump Jr. praised the platform for bypassing media narratives by letting people stake money on their beliefs. 1789 Capital describes itself as funding “the next chapter of American exceptionalism” and counts Trump Jr. among its partners. The Trump family has expanded its portfolio with ventures in finance, golf, hotels, telecom, and crypto, aligning with the president’s policies.
