Polymarket Competitors & Sites Like Polymarket (2026)
Polymarket is the biggest prediction market, but it is not the only one. Here are the main competitors and how they compare, so you can pick the right platform.

The main alternatives
Kalshi is the closest competitor: a CFTC-regulated US exchange with bank funding and a vetted, finance-heavy menu, but higher per-trade fees. Manifold uses play money and is great for learning without risk. PredictIt is a long-running, US-academic-licensed market with small position caps. Each suits a different trader.
On fees, breadth and liquidity, Polymarket leads for most active traders. Kalshi wins if you want regulated US access with a bank account rather than crypto.
How to choose between them
Pick by what matters most to you. If it is the lowest fees, the widest range of markets and deep liquidity, choose Polymarket. If it is simple bank funding with US regulation, choose Kalshi. If you want to practice with zero financial risk, start on Manifold's play money. If you specifically want the long-running US political markets, PredictIt is worth a look despite its position caps.
There is no rule that you must pick only one. Many active traders run accounts on both Polymarket and Kalshi and route each trade to whichever shows the better price, which is the simplest way to get the best of both.
