FAQ
- Can a sitting VP (Vance) win the Republican nomination?
- Historical precedent shows Vice Presidents possess structural advantages but face no guarantee of success. George H.W. Bush secured the Republican nomination in 1988 following Reagan; Al Gore failed to capture the presidency in 2000 despite his VP status. Prediction markets currently position Vance as the leading contender whilst acknowledging meaningful uncertainty.
- When do 2028 nomination markets resolve?
- Both Republican and Democratic nomination contracts settle following conclusion of their respective party conventions — ordinarily scheduled for July or August 2028.
- Are there markets for specific primary states?
- Markets covering Iowa's caucuses and New Hampshire's primary typically become available 6-12 months ahead of voting — consult PolyGram's prediction market guide and the political markets section for current offerings.
