Polymarket describes itself as the world’s largest prediction market. It lets users bet real money on the outcome of future events, from elections to economic indicators.
The integration is available starting today. Authors on Substack can now add Polymarket data to their writing without leaving the platform.
The goal is to give writers access to what the market currently thinks will happen on any given topic. Prediction markets are often used as a real-time gauge of public probability estimates.
Polymarket made the announcement on its official social channels. The company said “journalism is better when it’s backed by live markets.”
Substack has grown into one of the largest independent publishing platforms. It hosts thousands of writers covering finance, politics, technology, and more.
The move connects two platforms that already attract a politically and financially engaged audience. Many Substack writers already reference prediction market data manually in their work.
What the Integration Does
The native integration removes the need for writers to screenshot or manually copy data. Market probabilities can now be embedded directly
