Political prediction markets are the most followed and most liquid markets in the space. **Here's where to find the best political markets in 2026 and what they're currently saying.**
Why Political Markets Are The Most Accurate
Political markets attract the most knowledgeable participants — political analysts, journalists, pollsters and activists who follow events closely. The result is that political prediction markets are generally the most accurate and most liquid category on every major platform.

FAQ
Can I trade on UK by-elections on Polymarket?
It depends on whether the community creates a market. Major UK by-elections and party leadership races typically get Polymarket markets. More obscure local elections are better found on Manifold Markets.
