Prediction market volumes are booming in 2026, on pace to more than quadruple this year alone and reach an estimated $1 trillion in the next four years, according to Bernstein.
Volumes have already surged in the first few months of this year, the investment bank wrote in a report Tuesday, with Kalshi and Polymarket, the two largest platforms, seeing about $60 billion in market volume year-to-date — more than the $51 billion in total prediction market volume in all of 2025.
Growth rates for the platforms rival the artificial intelligence boom, according to Bank of America. Analyst Julie Hoover in a note last week called Kalshi one of the “fastest growing non-AI companies” in the U.S. Weekly trading volume on Kalshi — which controls more than 90% of the U.S. prediction market — has surged to more than $3 billion today from about $100 million a year ago, she wrote.
While prediction market volumes initially jumped in 2024 around the U.S. presidential election, they eventually surpassed those levels in 2025 as sports, cryptocurrency and macroeconomic contracts became popular.
