FAQ

Can a sitting VP (Vance) win the Republican nomination?

Precedent demonstrates vice-presidential nominees possess structural advantages without guarantees. George H.W. Bush succeeded Ronald Reagan in 1988; Al Gore's 2000 campaign failed despite incumbency. Current prediction markets position Vance as leading contender whilst acknowledging meaningful uncertainty.

When do 2028 nomination markets resolve?

Nomination contracts across both parties settle following their respective national conventions, ordinarily scheduled for July and August 2028.

Are there markets for specific primary states?

State-level primary markets, particularly Iowa caucus and New Hampshire primary contracts, typically commence trading between six and twelve months preceding those contests — consult PolyGram's regulatory status and political markets offerings for current availability.
