Péter Magyar's swearing-in as Hungary's prime minister on May 9, 2026, following his Tisza party's supermajority victory (141 seats) in the April 12 parliamentary election, has driven trader consensus to 100% certainty on Polymarket. This landslide ousted Viktor Orbán after 16 years, propelled by voter backlash against economic woes, corruption allegations, and EU tensions, enabling swift National Assembly convening and government formation within constitutional timelines. With Tisza's dominance securing legislative control, challenges like a no-confidence vote or resignation appear remote absent extraordinary developments such as health crises, scandals, or legal challenges to the election results. Upcoming cabinet confirmations and policy rollout could further solidify his position.
