Top 5 Prediction Markets in the U.S. (2026 Ranked List)

Top 5 Prediction Markets in the U.S. in 2026

The U.S. prediction market landscape in 2026 is more competitive and more legitimate than ever. Before diving into individual reviews, the table below shows an overview of how the top prediction markets compare based primarily on the disclosed or estimated 2025 valuations.

Platform	Best For	Payment Methods	Regulated Status	Valuation (2025 est.)
Kalshi	Serious traders, macro & political markets	USD (debit cards, bank & wire transfers, crypto)	CFTC-regulated	$11 billion

PredictIt	Political forecasting, research users	USD (bank transfer)	CFTC-approved	Undisclosed

1. Kalshi

Kalshi sits at the top of our list of the biggest prediction markets in the U.S. because of its remarkable funding success in 2025, which valued the company at $11 billion following a Series E funding round. On top of that, it made $263.5 million in fee revenue in 2025, most of it coming from sports.

Kalshi is privately held and operates under direct oversight from the CFTC, providing users with legal clarity and transparent settlement rules.

In 2026, Kalshi continues to dominate macro-style markets, including elections, inflation, interest rates, and economic data releases. Pricing is clean, and the platform is increasingly attracting traders who treat event contracts as derivatives rather than bets. Kalshi also offers a VIP program for high-volume accounts.

2. Polymarket

Polymarket is one of the most talked-about names in the prediction market space. The platform is built on the Polygon network and lets users trade USDC-based event contracts on topics ranging from politics and economics to pop culture, sports, and cryptocurrency prices.

After blocking users from the United States in 2022 under regulatory pressure, Polymarket returned in late 2025 by adopting a more compliant approach. The platform acquired QCEX, a CFTC-licensed derivatives exchange, and received a no-action letter from the CFTC allowing it to offer event contracts through approved channels to U.S. users.

While it secured $2 billion in funding from Intercontinental Exchange (ICE), the New York Stock Exchange’s parent company, in October 2025, its $9 billion valuation is still lower than Kalshi’s. Considering that Polymarket reintroduced itself to the U.S. market in Q4, its revenue is still negligible.

3. ForecastEx

ForecastEx takes a very different approach to prediction markets. Instead of feeling like a standalone app, it operates inside the world of traditional finance through Interactive Brokers. ForecastEx focuses on macroeconomic and policy-driven event contracts, attracting a more analytical audience. It only started offering sports contracts at the end of 2025.

In 2026, ForecastEx has firmly positioned itself as the “serious trader’s” prediction market. It benefits from Interactive Brokers’ deep liquidity and professional-grade infrastructure, which adds a layer of trust that newer platforms often lack.

Since it’s part of IBKR, it does not have a separate valuation, and its financial results are consolidated within its parent company’s reports. IBKR reported net revenues of over $6 billion for 2025.

4. FanDuel Predicts

FanDuel Predicts represents one of the most high-profile moves by a mainstream sportsbook into prediction-style markets. Originally a sportsbook and daily fantasy giant, FanDuel recently expanded its prediction market feature nationwide, including key states like California, bringing event contracts to a much broader audience. However, their sports offer is currently available in only 18 U.S. states.

FanDuel Predicts isn’t as deep or varied as dedicated platforms like Kalshi or Polymarket, but it has massive reach and ease of use on its side. Because it’s integrated into a familiar betting app, users can dip their toes into prediction markets without a steep learning curve. Odds and market formats are designed to feel intuitive, making it a great first stop for casual traders.

There are still no specific details on FanDuel Predict’s separate valuation since it launched at the end of 2025, and it operates as a part of the Flutter Entertainment group, which plans to invest $200–$300 million into the prediction market product in 2026.

5. PredictIt

PredictIt has long been one of the most recognizable names in political prediction markets. It was originally launched with an educational/exploratory lens and a loyal user base that values thoughtful debate and forecasting. However, the platform has received CFTC approval to become a fully licensed derivatives marketplace. 

While its markets skew heavily toward elections, policy outcomes, and geopolitical events rather than sports or finance, PredictIt remains a go-to destination for U.S. users interested in political probabilities and public policy outcomes.

PredictIt does not raise venture capital or seek a market cap. Due to its niche positioning, estimates of its 2025 revenue remain at $5–$10 million despite its high fees.

Key Prediction Market Trends for 2026

Prediction markets have moved fast over the last year, and it seems that 2026 will be even busier. What once felt like a niche is now pushing into the mainstream, with major finance and sports apps integrating prediction-style features and bringing them closer even to casual users.

Furthermore, liquidity is bound to remain one of the major arenas for establishing dominance. Platforms are competing hard to attract traders, tighten spreads, and deepen markets, because better liquidity now separates the serious players from the rest.

At the same time, there’s a growing tug-of-war between federal approval and state-level resistance, especially in regards to sports contracts on prediction markets. While CFTC-regulated markets are legalized nationwide, some states are pushing back and succeeding, with Massachusetts recently blocking Kalshi sports markets in that state.

Important: Due to ongoing legal battles between major prediction market platforms and state governments, always verify the legality of a specific market in your home state before trading.

Insider Tip

Conclusion

Prediction markets have come a long way. It has been a turbulent ride from the days of niche platform classification into regulated platforms with real influence. Kalshi’s regulatory wins have been a turning point, as has Polymarket’s recent return to the U.S. While Kalshi currently dominates the U.S. market, 2026 will most likely see Polymarket, FanDuel Predicts, and other contenders push harder and seriously challenge its top spot.

While major betting brands are already entering the prediction market space and improving fast, you must remember that trading contracts on these platforms isn’t risk-free. Even though trading is not classified as gambling, prices move, and losses can be incurred. Therefore, always use smart bankroll rules and follow responsible gambling guidance to keep trading sustainable.
