DISPATCH FROM THE PROBABLE FUTURE — If the speculators on Polymarket have read the tea leaves correctly, the presumed favourite for the 1600 Pennsylvania Avenue address in 2029 is, at best, a one-in-five proposition. With election day fixed for November 7th, 2028, the markets are issuing a stern advisory: this contest belongs to no one yet.

The arithmetic is bracing. A 21-cent probability, per Polymarket's current consensus, means that for every dollar wagered on the frontrunner's triumph, the market expects a loss nearly four times out of five. Some $4.4 million in fresh capital changed hands on that question in a single day — a figure that speaks not to certainty, but to the electrifying absence of it. Prediction markets, which aggregate the cold calculations of thousands of self-interested forecasters, have seen fiercer convictions dissolve before a single ballot is cast.

A late entrant, a scandal, a party realignment, or the inexorable churn of economic fortune could redraw this map entirely between now and autumn of 2028.
