Market context

The United States will hold its 2028 presidential election on 7 November, with the winner determined by Electoral College majority. The race remains wide open given that incumbent President Joe Biden has signalled he will not seek re-election, fundamentally reshaping the field. Democratic frontrunners include Vice President Kamala Harris alongside governors and senators still testing viability, whilst Republican contenders centre on former President Donald Trump, who leads most early polling despite ongoing legal proceedings. The 1% implied probability reflects the market's assessment that no single candidate has yet secured sufficient momentum or delegate commitments to be considered the presumptive winner at this stage.

Historical precedent suggests wide-open cycles without an incumbent candidate produce volatile markets. The 2008 Democratic primary saw Barack Obama overcome Hillary Clinton despite trailing significantly in early 2007, whilst 2016 saw both major-party nominees emerge as relative outsiders to establishment expectations. Current polling carries limited predictive value this far from November 2028, with candidate consolidation, debate performance, and economic conditions likely to reshape the landscape substantially.

Key catalysts include the Democratic National Convention scheduled for August 2028, where Harris or an alternative nominee will be formally selected. Republican delegate allocation accelerates through spring primaries, with Super Tuesday results in March typically narrowing the field. Traders should monitor third-party candidacy filings, which could fragment vote share in competitive states, alongside macroeconomic data releases and any developments in Trump's legal cases that might affect his viability as a general-election candidate.
