In a stunning twist during the Dutch elections on October 29, 2025, prediction markets Polymarket and Kalshi saw traders lose millions after heavily backing Geert Wilders' nationalist PVV party. Despite late polls showing a surge for the centrist D66 party, markets remained stubbornly bullish on PVV until exit polls triggered a violent 5%-to-100% price swing, liquidating overconfident long positions. This event reveals how ideological conviction can override market rationality, with data-driven traders profiting from the volatility while true believers held losing bets. Meanwhile, the $6.3B prediction market industry faces growing scrutiny as platforms jockey for dominance ahead of Polymarket's anticipated US relaunch.
How Dutch Election Bets Went Spectacularly Wrong
Up until election night, Polymarket contracts showed 85% confidence in a PVV victory, with Kalshi traders similarly positioned. "I've never seen such divergence between polls and market prices," noted a BTCC analyst. "Traders treated this like a political meme stock rather than a data-driven market." Final results gave both PVV and D66 26 seats in the 150-seat parliament - a catastrophic 11-seat drop for Wilders' party that few in prediction markets anticipated. The resulting liquidation cascade wiped out millions in long positions within minutes when exit polls dropped.
The Psychology Behind Failed Election Bets
Polymarket data reveals fascinating behavioral patterns: 72% of losing PVV positions were held until expiration, suggesting ideological commitment outweighed financial sense. "These weren't trades - they were political statements," observed one market maker. Meanwhile, traders like "Wisser" and "ciro2" banked six-figure profits by shorting PVV after late polls showed D66 gaining. The episode demonstrates how prediction markets can reflect participant biases rather than objective probabilities - especially when crypto traders (traditionally right-leaning) dominate the action.

Lessons From the Prediction Market Meltdown
The Dutch election offers three crucial lessons for prediction market participants:
- Markets can stay irrational longer than you can stay solvent (especially with leveraged positions)
- Ideological trading creates exploitable inefficiencies
- Late poll movements often contain more signal than early market positioning
