Key Takeaways

• Traders repriced the field as a White House trade-policy headline hit, with the market still led by Newsom rather than a clear runaway favorite.

The White House will not extend the U.S.-Mexico-Canada trade agreement, according to a report published on July 1. The report framed the decision as a clear stance on the future of the pact rather than a push for an extension. The headline comes as trade policy remains a prominent political issue, with implications for cross-border commerce and supply chains. The report did not provide further detail in the available excerpt beyond the White House’s position.

Beyond the 2028 Primary: Other High-Volume Geopolitical and Macro Contracts Polymarket Traders Are Tracking

Beyond the 2028 primary jockeying, Polymarket traders are also allocating size to big-ticket international political risk, where liquidity can move faster on a single headline. In Brazil’s Presidential Election contract, Luiz Inácio Lula da Silva leads at 57.5% with $108,349,395 in matched volume after an 8.0-point swing, while the Next French Presidential Election market is more fragmented, with Jordan Bardella topping the book at 25.5% on $106,440,127.
