For a long time, prediction markets have been labeled as "academic experiments," "tools for election season public opinion," or even "derivatives of sports betting." They always seemed tied to high-profile events, rarely recognized as true financial infrastructure.
But the data from 2026 is rewriting this narrative.
From the accurate forecasting of the 2024 US presidential election, to the first week of the 2026 World Cup seeing sports trading volumes surpass $7.18 billion, and leading platforms reaching valuations of over $10 billion, prediction markets are undergoing a transformation reminiscent of the early days of the options market: professionalization, institutionalization, and infrastructuralization. They are evolving from a marginal event-trading tool into a financial infrastructure that prices real-world uncertainty.
Explosive Market Growth: Clear Track Advantages
The rise of any financial infrastructure depends on a sufficiently large market and a steep growth curve. Prediction markets fit both criteria perfectly.
Looking back at 2024, the total trading volume across the sector was just $15.8 billion. By 2025, this figure soared to $63.5 billion, marking a nearly fourfold year-over-year increase. Entering 2026, growth accelerated even further: May alone saw $29.4 billion in trading volume, and the first week of June added another $6 billion. Just twelve months prior, monthly trading volume was only $1.2 billion.
Research from Galaxy Digital shows that prediction market trading volume in 2025 exceeded $44 billion for the year, dominated by Polymarket and Kalshi. Investment bank Bernstein estimates total transaction volume will reach $240 billion in 2026, a staggering 370% jump from the previous year. What excites institutional investors even more is the long-term outlook: with a projected compound annual growth rate of about 80% from 2025 to 2030, annual trading volume could break the $1 trillion mark by 2030.
Such a growth trajectory is rare in the financial industry. For a still-emerging sector, these numbers signal that smart money is betting on a soon-to-explode new blue ocean.
From "Election Tool" to All-Scenario Coverage: Expanding Application Boundaries
The key to prediction markets becoming financial infrastructure lies in their expanding use cases, far beyond their origins in election forecasting.
During the 2024 US presidential election, Polymarket users predicted Trump’s victory a month in advance, thrusting the platform into the spotlight of millions. Academic studies found Polymarket outperformed traditional polls in forecasting the 2024 election, especially in swing states.
But what truly changed the industry narrative was what happened after the election: trading volume didn’t vanish. The sports market picked up the momentum. By the end of 2025, sports accounted for 85% of Kalshi’s trading volume. Technology and science markets grew by 1,637% year-over-year, while economic markets increased by 905%. Categories such as entertainment, crypto, politics, and culture are showing stronger user growth and better trading retention structures.
After the 2026 World Cup kicked off, prediction markets quickly became the hottest topic in crypto. In the first week, nominal sports trading volume hit $7.18 billion—a new record. Polymarket’s 24-hour revenue reached $1.18 million, surpassing Hyperliquid. Kalshi benefited from positive regulatory signals from the CFTC regarding sports event contracts, with sports trading volume exceeding $1 billion for two consecutive days.
A recent report from Korean venture capital firm Hashed noted that prediction markets are evolving from simple betting platforms into "next-generation information infrastructure" capable of aggregating collective intelligence, with potential applications even in evaluating AI’s predictive capabilities.
From Retail Speculation to Institutional Entry: Strengthening Financial Attributes
Prediction markets were once seen as a "small-stakes game" for retail traders. The most notable change in 2026 is the acceleration of institutional capital entering the space.
In March 2026, federally regulated prediction market platform Kalshi completed a new funding round of over $100 million, pushing its valuation to $22 billion—double its $11 billion valuation in December 2025. Polymarket is seeking to raise $400 million at a $15 billion valuation, with ICE (parent company of the New York Stock Exchange) promising up to $2 billion in investment.
Institutional trading is ramping up at an astonishing pace. In May 2026, Kalshi’s monthly trading volume reached $17.3 billion, up 2,500% year-over-year, accounting for 61% of the prediction market sector’s total $28.4 billion trading volume. That same month, Clear Street became the first regulated institutional futures commission merchant (FCM) to join Kalshi, paving the way for institutional access to prediction market ETFs and institutional-grade trading infrastructure.
Galaxy Digital has launched event-driven OTC trading services for institutions, completing its first $10 million transaction. Zane Glauber, Galaxy’s global distribution head, stated that prediction markets have become a core tool for institutional investors to express macro views, with event contracts providing "precision hedging tools akin to a scalpel."
Meanwhile, both Polymarket and Kalshi announced their entry into perpetual futures trading. Polymarket’s perpetual contracts beta is open to select users, while Kalshi has received CFTC approval to list Bitcoin perpetual contracts (BTCPERP). Expected trading assets include cryptocurrencies like Bitcoin, commodities such as gold, and stocks like Nvidia, with leverage up to 10x.
All these signals show that prediction markets are shifting from "betting on outcomes" to "trading risk," with their identity as financial infrastructure being repeatedly validated by the market.
Regulatory Framework Clarifies: Compliance Path Becomes Defined
Financial infrastructure cannot remain outside the scope of regulation for long. In 2026, prediction markets saw a historic breakthrough in regulatory clarity.
On June 10, 2026, the US Commodity Futures Trading Commission (CFTC) released a 267-page proposed rule, planning major changes to the review process for event contracts. The document clarified the definitions of "involvement" and "gambling"—two core terms hotly debated during previous litigation between Kalshi and the government. The proposal included a non-exhaustive list specifying contract types exempt from public interest review, such as economic indicators, foreign exchange rates, election results, legislative and appointment outcomes, and award contests, making it easier for these contracts to be listed.
Under CFTC Chairman Michael Selig, regulators are moving swiftly to establish clear road rules for prediction markets. The proposal marks a shift from "broad prohibition" to a "structured review" framework, signaling a much more open stance from the CFTC.
This regulatory breakthrough is significant. The sharp reduction in compliance uncertainty will clear the way for more traditional financial institutions to enter prediction markets. Platforms like Kalshi, once they secure CFTC compliance, can become institutional-grade venues for event trading, just like the NYSE and Nasdaq.
Enterprise Applications Take Hold: Insurance and Hedging Use Cases Mature
Another compelling sign that prediction markets are becoming financial infrastructure is their move beyond speculative trading into real-world enterprise risk management.
In May 2026, Spanish football club Osasuna, through insurance broker Howden, purchased relegation risk protection on Kalshi, paying a premium of about $1.4 million for a potential payout of $6.9 million if relegated. The transaction involved sports insurance brokers, market makers, and quantitative trading firms—familiar Wall Street roles. This wasn’t speculation; it was genuine risk management.
Osasuna ultimately avoided relegation, meaning it lost the premium but retained its La Liga spot and the associated commercial value. This is standard hedging: paying a predictable cost for a financial safety net against an unpredictable event.
From a broader perspective, prediction markets are reshaping the traditional insurance industry. When disasters like hurricanes and wildfires occur more frequently and intensely than actuarial models predict, traditional insurers find themselves "unable to price, unable to pay, and unwilling to insure." Prediction markets offer a more flexible risk dispersal mechanism—spreading one person’s large risk across a group, echoing the origins of modern insurance at London’s Lloyd’s Coffee House over three centuries ago.
Sports relegation hedging is just the tip of the iceberg. Prediction markets’ enterprise applications can extend to commodity price volatility, supply chain disruption, box office hedging, macro policy shifts, and more. As Galaxy Digital’s traders put it, event contracts provide "precision hedging tools akin to a scalpel" for enterprises.
Conclusion
Prediction markets are evolving from a marginal event-trading tool focused on elections and sports into a financial infrastructure capable of pricing uncertainty. Four clear foundational logics support this view:
First, the scale is large enough. In 2026, monthly trading volume has surpassed $29.4 billion, with annual transaction volume projected to break $1 trillion by 2030—this is no longer a niche sector.
Second, the applications are broad enough. From presidential elections to World Cup matches, from crypto asset pricing to macroeconomic indicators, from enterprise risk hedging to insurance alternatives, prediction markets are reaching every corner of the financial landscape.
Third, the participants are "heavyweight" enough. With Kalshi valued at $22 billion and Polymarket at $15 billion, and top-tier capital like ICE, Sequoia Capital, and Coatue doubling down, plus Galaxy Digital launching dedicated event contract OTC services, prediction markets have moved beyond "retail betting"—they are now institutional-grade financial markets.
Fourth, the regulatory path is clear enough. The CFTC’s 267-page proposed rule released in June 2026, along with favorable US federal court rulings in the Kalshi case, together provide a foundational framework for prediction markets to move from gray areas to compliance and institutionalization.
The future is here. Prediction markets won’t just exist for elections or sports—they are becoming a core market tool connecting retail and institutional participants, used for hedging and pricing real-world uncertainty. For anyone interested in the cutting edge of finance, understanding prediction markets means understanding the underlying architecture of next-generation financial infrastructure.
