FAQ

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

Precedent indicates vice-presidential nominees possess structural advantages but face no guarantees. Bush Sr (1988) secured the Republican nomination following Reagan; Gore's 2000 campaign as sitting VP ended unsuccessfully. Current prediction markets reflect Vance's leading position without assigning overwhelming certainty.

When do 2028 nomination markets resolve?

Nomination outcomes crystallise following each party's summer convention — anticipated for July or August 2028.

Are there markets for specific primary states?

State-level primary markets, including Iowa and New Hampshire contests, typically commence 6-12 months prior to voting — consult PolyGram's political markets offerings for current availability.
