Platforms like Polymarket and Kalshi are enabling bets on US stock movements and corporate events, bypassing traditional exchange regulations. With over $220 million in volume, these platforms lack standard investor protections like insider trading monitoring and corporate disclosures. Investors should note that these are speculative betting venues, not stock exchanges, and carry significant financial risks.
A new category of financial platforms, known as prediction markets, has expanded from betting on elections and geopolitical events to taking wagers on the performance of major US stocks. Platforms such as Polymarket and Kalshi are now listing contracts that track the prices or corporate events of large companies like Nvidia, Tesla, Apple, and Alphabet. While these entities present themselves as tools for hedging risk, they function differently from regulated exchanges like the New York Stock Exchange or the Nasdaq.
Unlike a traditional stock market where an investor buys a share of a company, these platforms typically use a binary betting model. Users wager on whether a stock price will hit a certain level or if a specific corporate event, such as a product launch, will occur within a set timeframe. If the event happens as predicted, the user wins; if not, they lose their wager. Blockchain data indicates that this sector has seen substantial growth, with more than $220 million in volume across equity-linked markets in less than a year.
The primary concern for investors is the lack of oversight. Traditional stock exchanges are governed by strict regulations, including requirements for companies to disclose financial results, and laws that prohibit insider trading. Prediction markets operate in a regulatory gray area. Because these platforms are not registered as stock exchanges, they are not required to enforce the same standards that protect retail investors from market manipulation. This creates an environment where information about corporate events could potentially be used unfairly, without the standard checks and balances found in the formal financial system.
There is currently an ongoing conflict between US regulators, specifically the Securities and Exchange Commission and the Commodity Futures Trading Commission, over who has the authority to govern these platforms. While legal experts suggest that these equity-based contracts should fall under the jurisdiction of the SEC, the decentralized and often offshore structure of these operators makes enforcement difficult. Some advocacy groups have flagged that this lack of regulation leaves participants exposed to financial distortion.
For investors, the distinction between a regulated market and a prediction platform is critical. Participating in these markets involves betting rather than investing, and users do not benefit from the legal protections that apply to equity trading. As legislative and regulatory pressure on these entities continues to mount, the next important update for market participants will be any formal intervention or ruling by US authorities to clarify the legal status of these equity-linked betting contracts.
