In the dynamic landscape of online betting, prediction markets are gaining traction as a sophisticated way to wager on future outcomes, extending beyond traditional sports bets. If you’re accustomed to sports betting—wagering on match results or individual performances—you’ll find prediction markets familiar yet expansive, allowing trades on a wide array of events like elections or market trends. As we close out 2025, with the sector showing steady momentum, let’s explore what prediction markets entail, the key players involved, their current market dynamics, growth trends, and a balanced view on future prospects, including growth opportunities and regulatory considerations.
What Are Prediction Markets?
Prediction markets online platforms allow users to trade contracts based on the likelihood of specific future events. They’re akin to a futures market for probabilities: participants buy or sell “shares” in binary outcomes, such as “Will Team X win the championship?” If you think yes, you might purchase “yes” shares at 55 cents; a correct outcome yields $1 per share, while an incorrect one results in zero.
The strength of these markets comes from aggregating diverse trader insights, with strong liquidity yielding comes more reliable forecasts than individual experts or surveys. Historically, they’ve demonstrated accuracy in fields like politics and economics. For sports bettors, they offer an alternate layer, with contracts on games, stats, and awards that complement, or more directly, completely mirror standard OSB options.
Unlike odds in traditional Sportsbooks which move on select information, prices in Prediction markets exchanges tend to adjust more dynamically with trading activity, mirroring real-time probability shifts. Originating from academic experiments in the 1980s, such as the Iowa Electronic Markets, they’ve evolved rapidly thanks to technological advancements and evolving regulations.
Key Competitors in Prediction Market Arena
The space features a blend of regulated traditional platforms and blockchain-driven decentralized ones, creating a competitive environment. By late 2025, a handful of leaders hold sway, though the field is broadening.
- Kalshi: As a CFTC-regulated entity, it commands 66-70% of the market share, with annualized volumes projected to exceed $50 billion. Targeting U.S. audiences, it spans politics, economics, and sports. Federal regulatory compliance attracts institutional interest.
- Polymarket: This blockchain-based leader captures about 31% of the market, with $434 million in weekly trade volume. It’s the go-to for varied topics, including crypto and international events. Recent $2B investment from NYSE parent Intercontinental Exchange indicates strong belief in the companies technology.
- Other Notable Players: Established sportsbooks FanDuel and DraftKings are venturing in, competing with specialists such as Underdog and Fanatics Markets in sports-centric offerings. Decentralized options include Drift BET on Solana and Augur, while Robinhood and Crypto.com incorporate prediction elements. Up-and-comers like TryLimitless (2% share), Opinion Labs, and Manifold Markets are among the growing list of smaller players seeking to introduce fresh innovations.
User engagement differs significantly: Robinhood boasts 26.9 million funded accounts while Polymarket sees around 502,000 monthly actives. Competition is heating up, with platforms focusing on differentiation through institutional features and partnerships.
Market Share and Growth Trends
Dominance is concentrated, with Kalshi at 66-70% and Polymarket at 31%, while others like TryLimitless collectively holding onto smaller portions (~2%). This top-heavy structure underscores the importance of trust and scale for liquidity, but increasing entrants suggest potential for more distributed shares.
Growth has been robust, with monthly notional volume rising from below $100 million in early 2024 to over $13 billion by late 2025—a 130-fold increase. Specific categories, like economics markets, expanded 905% to $112 million this year. Projections indicate U.S. event-contract revenues could surpass $10 billion by 2030, a fivefold rise, with a scenario for $1 trillion in annual volume by decade’s end, fueled by sports (potentially 44% of volume) and wider use. The broader distributed prediction market might reach $95.5 billion by 2035.
Outlook: Growth and Regulatory Factors
The trajectory for prediction markets appears promising, with potential to become a staple in betting and forecasting, though tempered by practical challenges. On the positive side, they could integrate more deeply into everyday decision-making, serving as hedging instruments for institutions and individuals. Events like the 2026 World Cup may boost visibility and liquidity, drawing in more users. Innovations, including AI enhancements, and adoption by majors like DraftKings and FanDuel, suggest steady expansion.
However, growth isn’t without drawbacks. Pros include enhanced market efficiency and accessibility, fostering better-informed bets and broader participation. Cons involve risks like market manipulation in less-regulated spaces, volatility from speculative trading, and potential over-reliance on crowd wisdom, which can falter in unpredictable scenarios. Rapid scaling might also strain platform infrastructure, leading to liquidity issues or user disputes during high-stakes events.
Regulation plays a pivotal role in this balance. A 2024 U.S. court decision facilitated CFTC oversight, enabling growth for compliant platforms like Kalshi. This has encouraged mergers and mainstream entry, but operators must adhere to guidelines to prevent setbacks. Internationally, the landscape varies, with offshore crypto platforms facing inconsistent rules. Industry efforts for unified standards aim to promote integrity, but shifts in policy—such as under new governments—could introduce uncertainties. Overall, while regulations have supported progress, they could evolve to either accelerate or constrain development, depending on enforcement.
The Role of Prediction Markets in Betting
Prediction markets offer an intriguing evolution for sports betting, providing nuanced odds and insights that can sharpen strategies. With leaders like Kalshi and Polymarket at the forefront, and growth showing resilience, bettors stand to benefit—provided they navigate the pros and cons wisely. Regulatory developments either way will sway momentum and shape accessibility, pace of growth and sustainability.
