Why did Orbán lose?
Viktor Orbán, a man who for sixteen years was considered unsinkable, lost the election in a landslide. He lost in a manner that marks the end of an era. Péter Magyar’s TISZA party achieved a success comparable only to that achieved by Orbán in 2010. According to data released after the election, with a near-full recount, TISZA won approximately 53 percent of the list vote, Fidesz approximately 38-39 percent, and Mi Hazánk less than 6 percent. Seat forecast: TISZA approximately 138 seats in the 199-seat parliament, Fidesz approximately 54-55, and Mi Hazánk 6-7. A constitutional majority requires 133 seats. Magyar thus took more than just power. He was given the tools to completely dismantle Orbán’s system.
Turnout reached nearly 80 percent. This was a mobilization against the system, not a routine change of power. TISZA won in Budapest, but something else was more important: it broke through beyond the opposition’s metropolitan sanctuary. In the capital’s metropolitan area, in the country’s western regions, in industrial cities, among young people, in previously places controlled by the Fidesz apparatus, a wave of support that Orbán was unable to stem. The avalanche was the culmination of a process: Fidesz fatigue, a crisis in public services, corruption, a dirty campaign, and finally, fear of the authorities, whose movements have been increasingly volatile lately.

Why did Orban lose?
Fidesz’s economic system turned out to be more of a propaganda mechanism than a mechanism for building real prosperity.
For years, the Orbán myth has been based on a simple image: tough leader, stable state, growth, jobs, investment, national capitalism. Except that the average Hungarian doesn’t live off Minister Szijjártó’s daily press conferences about another battery factory. They live off salaries, food prices, rent, bills, the quality of hospitals, the state of the railways, and how much money is left in their wallet. And here, the balance sheet is merciless.
In 2010, when Orbán returned to power, Hungary’s nominal GDP per capita was about $13,200. Poland was at a similar level then, around $12,600. Romania was far behind, around $8,300. In 2024, the last full data from the World Bank, Hungary had a GDP per capita of about $23,300, Poland around $25,100, Slovakia around $26,000, the Czech Republic around $31,800, and Romania around $20,100.

What does this mean politically?
