Bush secured the presidency following Ronald Reagan in 1988; Al Gore failed as the Democratic nominee in 2000. Current prediction markets position Vance as the leading contender without overwhelming dominance.
When do 2028 nomination markets resolve?: Nomination markets for both parties conclude following their respective national conventions — ordinarily scheduled for July and August 2028.
Are there markets for specific primary states?: Markets centring on individual early contests such as Iowa and New Hampshire typically commence between six and twelve months prior to voting — consult PolyGram's political markets catalogue for current offerings.
