FAQ
- Can a sitting VP (Vance) win the Republican nomination?
- Historical precedent demonstrates vice-presidents possess structural advantages but face no guarantee of success. George H.W. Bush (1988) inherited Reagan's mantle successfully; Al Gore (2000) failed as the sitting VP. Prediction markets position Vance as the leading contender whilst acknowledging substantial uncertainty.
- When do 2028 nomination markets resolve?
- Both Republican and Democratic nomination contracts settle following their respective party conventions — ordinarily scheduled for July or August 2028.
- Are there markets for specific primary states?
- Individual state primary and caucus markets — including Iowa and New Hampshire — typically materialise between six and twelve months ahead of those contests. Polymarket versus alternative platforms each maintain dedicated political prediction sections where such offerings appear.
