The Democratic vice presidential slot for 2028 remains wide open more than two years before the general election, producing tightly clustered trader probabilities across a broad field of potential nominees. No declared candidates or formal primary process yet exists, so positioning reflects early name recognition, past national profiles, and speculation about who might complement a future presidential ticket rather than concrete campaign momentum. Recent cycles show vice presidential selections often hinge on electoral math in swing states, demographic outreach, and Senate or gubernatorial experience, factors that have not yet produced clear separation here. Midterm results, early primary polling, or high-profile endorsements could quickly reorder the market, while the absence of any dominant frontrunner keeps probabilities compressed among the leading names.
