From 100 million to 13 billion in 2 years: The rise of "prediction markets"

Author: Ye Huiwen Source: Wall Street News

Prediction markets are experiencing exponential expansion, rapidly transforming from a fringe activity into a multi-billion dollar financial sector. Driven by bets on sports, political, and economic indicators, monthly trading volume in this area has surged 130-fold in the past two years, marking a structural leap in the model of pricing and trading public event outcomes through "event contracts."

According to a recent report by cryptocurrency companies Dune and Keyrock, monthly betting amounts on platforms such as Polymarket and Kalshi have soared from less than $100 million at the beginning of 2024 to over $13 billion in November of this year. This dramatic shift not only highlights the massive influx of user funds into this emerging trading venue but also reflects the explosive growth in market demand for such "event contracts."

The surge in trading volume has triggered a repricing in capital markets. Kalshi recently completed a massive funding round at a valuation of $11 billion, while Polymarket also received a valuation of approximately $8 billion. Simultaneously, a key shift in the regulatory environment occurred, with Polymarket receiving approval from the U.S. Commodity Futures Trading Commission last month to operate in the United States. This not only legitimizes the industry but also further intensifies competition among leading platforms. This sector is rapidly integrating into the broader financial infrastructure. Through partnerships with mainstream media outlets such as CNN and CNBC, as well as Google Finance, prediction markets are evolving into a recognized tool for measuring the probability of real-world events. Their growing influence and predictive capabilities in various public events are beginning to challenge traditional analytical and statistical methods. Capital Influx and Soaring Valuations As the industry heats up, leading companies have received valuations of billions of dollars in recent months. This month, Kalshi raised $1 billion at a valuation of $11 billion, with a star-studded investor lineup including crypto investment firm Paradigm, Sequoia, Andreessen Horowitz, and CapitalG. Meanwhile, Intercontinental Exchange, owner of the New York Stock Exchange, announced in October that it would invest up to $2 billion in Polymarket, valuing the company at approximately $8 billion. These massive investments demonstrate the long-term optimism of traditional financial institutions and top venture capitalists regarding prediction markets as a new type of financial derivatives trading platform. Regulatory Battles and Compliance Paths Although sports betting is prohibited by law in many U.S. states, prediction market platforms argue that they offer financial contracts regulated nationwide by the U.S. Commodity Futures Trading Commission (CFTC), rather than traditional gambling. Polymarket, previously banned in the US, received CFTC approval last month to officially enter the compliant market by offering services through brokers and directly to clients. The prediction market gained prominence ahead of the 2024 US presidential election, with Polymarket's bets accurately predicting a decisive Trump victory, while traditional polls predicted a close race. This success significantly boosted public awareness of the industry. Market Landscape and Competitive Landscape: The report shows that while Polymarket previously dominated in trading volume, Kalshi has experienced rapid growth in recent months, and the two companies now have roughly equal market share. Last month, the total amount wagered on the two platforms combined was approximately $9 billion. As competition intensifies, both have announced a series of partnerships with major sports leagues and others, and launched intensive marketing campaigns. Currently, Google Finance has begun displaying probabilities based on betting data from both platforms, and Kalshi has further expanded its data's exposure in mainstream media by establishing deep partnerships with media organizations such as CNN and CNBC. Diversified Betting Targets Besides political elections, economic data and popular culture have also become popular betting targets. The report found that while sports betting on Kalshi far surpasses other categories, Polymarket's distribution across sports and politics is more even. Betting on economic events is growing rapidly for both companies; for example, Kalshi users currently predict an 80% probability that the Federal Reserve will maintain interest rates unchanged in January. Furthermore, prediction markets have extended their reach into the long tail: Kalshi users are predicting the Rotten Tomatoes score for the latest Avatar movie and the amount of snowfall in New York City this month; Polymarket users are betting on the winner of the latest season of the reality show Survivor, and the number of times Elon Musk will post on his X platform this week.
