Polymarket reportedly raises $300 million from Donald Trump Jr.’s investment fund

Polymarket has reportedly raised $300 million from 1789 Capital as part of a roughly $1 billion funding round, following a prior $200 million investment from the same firm. The raise comes as prediction markets face mounting litigation from states over sports wagers, while the Trump administration argues federal regulators should have sole oversight.

The investment underscores how politically connected capital is flowing into prediction markets just as their legal status is being contested. A shift toward federal oversight could help platforms scale nationally, but continued state resistance may keep regulatory uncertainty high.
