Polymarket, the $9 billion prediction market platform, describes itself as 'News 2.0' but a New York Times review found its social media feeds filled with hundreds of false and misleading posts. The company's accounts on X, TikTok, Facebook, and Instagram have amplified unproven claims from the Trump administration and baseless conspiracy theories, reaching nearly two million followers.

Despite positioning itself as a truth-seeking platform where users back predictions with money, Polymarket has repeatedly shared misleading information. Posts suggested Minnesota Governor Tim Walz had 'declared war' on President Trump and implied New York mayoral candidate Zohran Mamdani would win through rigged ballots. The company omitted that candidates' names commonly appear multiple times on NYC ballots due to party nominations.

Founded in 2020, Polymarket operates in a legal gray area, paying a $1.4 million fine in 2022 for not registering as a designated contract market. The platform gained prominence during the 2024 election and now offers U.S. users sports betting while maintaining international markets on topics from Taylor Swift's wedding to Iranian government stability. Critics say the company's social strategy, mixing news updates with memes and crude humor, creates a 'perverse incentive loop' where false information moves markets and generates engagement.
