Trump out as President by June 30?

Platform comparison

Market context

Donald Trump remains the sitting US President with no credible mechanism currently in place to force his resignation or removal before June 30, 2026, which explains the market’s 0% implied probability for him ceasing office. Historically, the only US president removed from office was Andrew Johnson via impeachment, though he survived the Senate vote; Richard Nixon resigned to avoid impeachment, and Bill Clinton was impeached but remained in power. No modern president has faced permanent removal without a catastrophic health event or voluntary resignation, and Trump’s legal and political entrenchment mirrors Nixon’s pre-resignation stance more than Johnson’s vulnerability.

Traders should monitor the 2026 congressional election schedule, particularly if results are close in states with Democratic governors, as recent reporting suggests Trump may invoke a national emergency to mobilise the National Guard and seize ballot boxes if Republicans face uncertainty [1]. Any announcement of resignation or removal would instantly resolve the market to “Yes”, regardless of when the action takes effect. Watch for shifts in federal worker protections under Schedule F, which could trigger internal administration turnover or loyalty crises [4], and track Kalshi’s parallel market on Trump announcing departure, which currently also shows 0% probability [3].

Polymarket and Kalshi diverge on fee structures and KYC requirements: Polymarket offers lower fees and minimal identity verification, while Kalshi mandates full KYC and US residency, affecting liquidity depth on this specific event. Decimal odds on Kalshi contrast with Polymarket’s implied probability display, though both platforms currently price this outcome at zero. Betfair and Smarkets, operating outside US regulation, may offer higher liquidity but lack the same settlement clarity on constitutional removal clauses. The market’s consensus remains absolute: Trump will not cease office by the deadline.
