Polymarket boom: Why regulation isn't slowing prediction markets

​Regulators are challenging Polymarket’s business model, but trading activity continues to surge. The apparent contradiction raises an intriguing question: What makes prediction markets so appealing, and why is their popularity proving so difficult to contain?

Polymarket trading surges amid regulatory battles

Trading volume on Polymarket’s U.S. exchange jumped 266% between June and October, rising from $4.04 billion to $14.77 billion, according to analytics platform TickerTracker. The figures measure contracts at their full payout value rather than the money deposited by traders, but illustrate the rapid growth in activity.

Sports-related speculation drove much of the increase. Combo contracts, which combine several predictions into a single position, accounted for $8.6 billion, or 58.2% of October’s volume. Standalone sports contracts contributed another $4.57 billion, or 31%, while political markets represented a much smaller share.

Polymarket’s commercial ambitions are growing alongside trading activity. The company said its annualized revenue run rate exceeded $1.8 billion, compared with over $1 billion in June. It is also reportedly seeking fresh funding at a valuation of approximately $21 billion. Meanwhile, U.S. states are challenging sports-related contracts under gambling laws, and several countries have restricted access to its international platform.

Why people are increasingly drawn to prediction markets

Polymarket’s appeal begins with a simple idea: almost any uncertain event can become something people trade. Unlike conventional financial markets, prediction markets let users speculate directly on outcomes, from sporting events and elections to economic decisions and technological developments.

The mechanism is straightforward. Traders buy “Yes” or “No” shares, typically priced between $0.01 and $0.99. A share costing $0.70 suggests traders assign a 70% probability to that outcome, as the maximum payout is $1. If the prediction proves correct, the buyer receives $1, earning $0.30 in profit before fees. Otherwise, the share becomes worthless, and the buyer loses $0.70. Prices move as traders buy and sell, reflecting changing expectations.

This simplicity attracts people who may never consider conventional investing. Understanding a football match or a political event requires different knowledge from analyzing corporate earnings. Users can speculate on subjects they already follow, turning familiar interests into financial positions. The ability to act on personal knowledge or a strong conviction makes participation feel more accessible than trading unfamiliar financial assets.

Prediction markets also combine entertainment with speculation. Sports offer frequent trading opportunities, while politics and breaking news generate public interest. Unlike conventional fixed-odds betting, traders can sell their positions before an event is settled, potentially profiting from changing expectations rather than waiting for the final outcome.

How Polymarket turned predictions into a business

Polymarket's popularity reflects a change in how people consume information. Its probabilities increasingly appear alongside opinion polls, analyst forecasts and news coverage, allowing audiences to see how traders assess upcoming events. Even people who never place a trade can follow these changing odds to understand how expectations are shifting.

Unlike opinion polls, prediction markets reflect positions backed by money rather than responses to survey questions. Participants have incentives to research events and respond quickly to developments, producing constantly changing prices. A surprise announcement can shift probabilities within minutes, making them an attractive reference point for journalists and audiences following breaking news. However, these estimates are not necessarily accurate. Limited liquidity, large individual positions and manipulation can distort probabilities.

Blockchain infrastructure has also helped Polymarket reach cryptocurrency users. Its international platform facilitates transactions using crypto technology, while its separate U.S. exchange operates under federal derivatives oversight. Competitors such as Kalshi are attracting investment, and traditional financial companies are exploring prediction markets, expanding the industry's reach beyond its original audience.

Why regulators cannot agree on Polymarket's future

Polymarket's legal difficulties stem from a basic disagreement: Are event contracts financial derivatives or gambling products? The distinction becomes particularly contentious when traders speculate on sports outcomes.

In the U.S., the Commodity Futures Trading Commission (CFTC) oversees registered derivatives exchanges, including Polymarket's U.S. operation. State authorities argue that certain sports contracts fall under gambling laws and require local licenses. On November 5, the CFTC directed federally regulated exchanges to end certain state-by-state access restrictions within 30 days or explain why they could not comply, creating a conflict with court orders requiring some operators to limit access.

Outside the U.S., authorities in several countries have restricted Polymarket's international platform over gambling and consumer protection concerns. Regulators also face questions about market integrity, including whether traders could profit from confidential information or manipulate prices that influence public expectations. Some contracts concern outcomes controlled by relatively few people, raising difficult questions about insider information and fair access.

Can Polymarket's popularity survive tighter oversight?

Polymarket's rapid growth demonstrates demand for event-based trading, but volume alone does not reveal how many people participate or whether activity can remain elevated. Its reliance on sports-related contracts also creates exposure to regulatory restrictions, while competition from Kalshi and other platforms is intensifying.

Interestingly, regulatory controversy may itself be attracting attention. Court battles and disputes over the legality of prediction markets generate headlines, introducing Polymarket to new audiences. Although there is no evidence that regulatory pressure directly causes higher trading volumes, the publicity may help explain why legal challenges and popularity are rising together.

Polymarket's longer-term prospects will depend on whether it can retain users under tighter rules and establish prediction markets as a credible source of information, rather than simply another form of gambling.
