From the trading floors of Polymarket comes a dispatch suggesting the Republican Party of 1928 — fond of its certainties — may find 2028 rather more turbulent. A single unnamed frontrunner commands 49 cents on the dollar for the nomination, a figure that speaks of dominance without quite delivering it. The party faithful may be preparing a coronation; the markets, for their part, are not yet ringing the bells.

The stakes are considerable. A nominee secured early commands the machinery of party fundraising, donor loyalty, and media attention — advantages that compound with time. Yet prediction markets, reporting a daily trading volume exceeding three million dollars on this question alone, assign the remaining 51% to the field entire. In the parlance of the exchanges, this is a favorite, not a certainty — a distinction that has humbled many a presumptive standard-bearer before ballots were cast.

Should a credible challenger emerge — from the governors' mansions, the Senate, or some corner of the party yet unannounced — that 49% could erode with startling speed.
