Prediction Market Platforms See Surge in Trading Volume

Polymarket reported a 24‑hour trading volume of about $38.3 million, with war‑related markets—most notably a US‑Iran peace‑deal contract—leading activity. The platform also hosts markets on cryptocurrency, artificial intelligence and even Elon Musk tweets.

In the United States, Kalshi, a federally regulated prediction‑market exchange overseen by the CFTC, has seen monthly trading volume grow from roughly $5 billion in late 2024 to about $24 billion by March 2026. Sports‑related contracts account for roughly 73 % of its activity, prompting debate over the line between financial trading and gambling.

Both platforms illustrate the rapid expansion of prediction markets as a financial product, drawing interest from investors, sports fans and technologists alike.
