In 2026, prediction markets are expected to gain widespread acceptance, projected to handle billions in trading volume with an expanding user base. Previously focused primarily on elections, prediction markets are now active in sports, cryptocurrency, macroeconomic events, technology, and pop culture.
Analysis from the Pew Research Center using data from The Block indicates that trading volume on platforms like Polymarket and Kalshi rose from under $5 billion in September 2025 to nearly $24 billion by April 2026. This figure surpasses the legal US sportsbooks' average monthly turnover of $14 billion. Sports, politics, and cryptocurrency are the dominant trading categories across these platforms, but their distribution varies: sports represents 80% of trading volume on Kalshi, while Polymarket sees sports account for 39%, with a combination of cryptocurrency and politics comprising 52% of its volume.
Prediction markets enable users to trade contracts based on the likelihood of future events happening. A contract valued at $0.78 indicates a 78% chance that the event will occur. Successful forecasts result in a $1 payout, while unsuccessful bets lead to forfeits. Polymarket has emerged as a leading platform in this space, allowing trading through crypto wallets, and it set a single-day transaction record of $425 million.
The classification of prediction markets as gambling remains contentious. Currently, these markets are not defined as gambling under U.S. law; they fall under the jurisdiction of the Commodity Futures Trading Commission (CFTC) and operate as financial markets that offer event contracts. However, many states oppose this classification, claiming that betting on sports events via these platforms closely resembles gambling. New York and Wisconsin have already embarked on initiatives to classify prediction markets as illegal under state laws, reflecting a lack of consensus and potential for extensive legal battles.
Internationally, the definition of prediction markets varies widely. In South Korea, authorities are investigating Polymarket users for possible illegal gambling activities, while regulators in the Netherlands imposed a €420,000 fine on Polymarket for delaying its withdrawal from the market, signaling stricter compliance measures globally.
As of 2026, prediction markets continue to gather momentum, with trading volume increasing from $5.4 billion in the first week of January to a peak of $6.5 billion by early April. Projections suggest that the overall market volume could increase fivefold over the year, averaging $25 billion weekly. Prediction markets, once noted merely for election forecasting, are now seen as innovative tools for accuracy in predictions compared to polls and expert opinions, with Brier probability scores around 0.09.
Kalshi's market valuation doubled to $22 billion following a $1 billion fundraising round in March 2026, while Polymarket's valuation grew from $9 billion to $15 billion. The consistent growth reflects a deeper integration of prediction markets into traditional finance, attracting more serious engagement from institutional investors. Recent legal disputes over platform credibility, including a lawsuit against Polymarket regarding Bitcoin market settlement issues, further highlight the industry's evolving landscape.
Looking forward, the prediction market ecosystem has matured significantly over the past year, now accounting for over $20 billion in monthly trading volume. With improved regulations, institutional investments are increasing. The introduction of AI technologies accelerates price discovery, while decentralization enhances global access to these markets.
Kalshi has seen its revenue triple annually since last November, approaching $2 billion in 2026. Bernstein estimates that by 2030, prediction market volumes could soar to $1 trillion, reflecting an increase from about $51 billion last year to a projected $240 billion by the end of the current year.
Noteworthy is the increasing role of technology giants like Meta, which is developing a competing application aiming to utilize gaming money, thus navigating around certain legal restrictions. As for trading volume contributors, sports have begun to overtake politics. In March 2022, 87% of Kalshi’s trading volume stemmed from sports events. Similarly, Polymarket’s markets related to the World Cup saw significant spikes in trading activity.
Regulatory dynamics continue to shift, with Kalshi’s request to exempt sports contracts from New York’s gambling laws denied, reflecting bolder regulatory stances. Generally, the clarity surrounding regulatory frameworks is improving, with Polymarket receiving CFTC approval to onboard U.S. brokers directly, adapting quickly to changing legal landscapes.
This growth has also led to the emergence of new categories within prediction markets, including technology and science realms, which are gaining traction this year.
Overall, prediction markets are at a pivotal point, merging areas of finance, gambling, media, and public opinion, shaping the future of market dynamics in the years to come.
