Kalshi Expands Beyond Prediction Markets With U.S. Stock Index Futures

Kalshi is moving further beyond prediction markets with the launch of a new perpetual futures contract tied to the U.S. stock market.
The new product, called US500PERP, tracks Kalshi’s US 500 index, which covers 500 of the largest companies in the United States. It allows traders to take long or short positions on the index without the contract having a traditional expiration date.
The launch is another sign that Kalshi has ambitions beyond event contracts. The company increasingly appears to be building a broader financial exchange, with prediction markets becoming one part of a much larger trading platform.
Kalshi’s new US500PERP product provides exposure to the U.S. stock market through what is known as a perpetual future.
Traditional futures normally expire on a specific date. A perpetual future does not. Traders can keep a position open without repeatedly moving into a new contract, while funding payments are used to help keep the contract price close to the value of the underlying index.
Kalshi originally filed the product with the Commodity Futures Trading Commission in August. The CFTC approved US500PERP on October 3, classifying it as an equity index future.
That makes it very different from the Yes/No contracts normally associated with prediction markets.
A traditional Kalshi event contract might ask whether the Federal Reserve will cut interest rates or whether a team will win a championship. US500PERP instead rises and falls with the stock market index.
A perpetual future is a financial contract that lets traders take a position on whether an asset or market will rise or fall.
The main difference from a normal futures contract is that there is no traditional expiration date.
That means someone taking a long position expects the market to rise, while someone taking a short position expects it to fall. The position can remain open as long as the trader meets the requirements of the contract.
Perpetual futures became particularly popular in cryptocurrency markets, especially on offshore trading platforms. Kalshi began bringing the product into the regulated U.S. market earlier this year with cryptocurrency perpetuals. The company has since expanded into metals including gold, silver and platinum, with copper and the US 500 index becoming its latest additions.
According to CFTC filings, Kalshi’s expansion is already moving beyond a single stock-index product. The regulator approved both US500PERP and a copper perpetual future on October 3, while additional products tied to interest rates and individual stocks remain under review.
So, the US 500 contract is not a one-off launch. Kalshi has spent much of 2026 expanding beyond the prediction markets it is best known for. Let's break it down:
In April, the company launched a dedicated commodities hub with more event contracts tied to physical markets. In May, it moved beyond event contracts altogether with the launch of perpetual futures, initially focusing on cryptocurrencies.
The expansion has accelerated since then. Kalshi launched Kalshi Pro, a more advanced trading platform, in July. In September, it introduced 24/7 perpetual futures tied to gold and silver, allowing U.S. traders to take long or short positions on precious metals without a traditional expiration date.
Kalshi has also been expanding how people can access its markets. Brokerage infrastructure provider Alpaca announced support for Kalshi event contracts in August, while Public added Kalshi-powered prediction markets in September.
The new US 500 perpetual future is therefore part of a much bigger push. Kalshi is adding more assets, more trading tools and more ways for customers to access its exchange.
That helps explain why the company increasingly looks less like a dedicated prediction-market platform and more like a broad financial exchange.
The simple answer is that Kalshi wants to become more than a prediction market.
The company built its name around event contracts, but it now sees an opportunity to offer a much wider range of financial products through the same regulated exchange.
Kalshi CEO Tarek Mansour described stock market exposure as the next step toward the company becoming a “full-service financial exchange.”
That strategy gives Kalshi access to a much larger potential market.
Prediction markets allow traders to take positions on specific questions and events. Financial markets, by comparison, operate continuously and attract traders interested in stocks, commodities, currencies and cryptocurrencies.
Kalshi can now try to serve both groups.
The company has also positioned regulated U.S. perpetual futures as an alternative to products that have traditionally been more widely available through offshore platforms. When Kalshi first announced perpetual futures in May, it called the launch its biggest expansion beyond event contracts and said it planned to build a broader derivatives exchange.
Editor's notes
“Kalshi’s recent launches make it clear that prediction markets are only part of the plan. The company is building toward a much broader U.S. trading platform, and the US 500 launch is probably the clearest sign of that yet”
That may be the most important part of the launch.
Kalshi is still one of the largest names in U.S. prediction markets, competing with platforms including Polymarket and prediction-market products offered through Robinhood.
But the companies are increasingly moving into each other's territory.
Robinhood has expanded aggressively into prediction markets while continuing to offer stocks, options, crypto and futures. Kalshi is moving in the opposite direction, starting with prediction markets before expanding into more traditional financial products.
The line between prediction markets and regular trading platforms is therefore becoming less clear.
This is also happening as prediction markets expand deeper into financial events. Contracts tied to earnings, economic data and individual companies already allow traders to take positions on specific financial outcomes without directly buying the underlying stock. We recently looked at that question in more detail in our guide to stock prediction markets.
US500PERP takes Kalshi another step further because it is no longer a prediction about a specific event. It is direct exposure to the movement of a financial index.
Stock indexes are unlikely to be the end of Kalshi's expansion.
The CFTC has already approved Kalshi perpetual futures tied to cryptocurrencies and metals, while additional products remain in the regulatory pipeline. Reuters has also reported that Kalshi is preparing a perpetual contract tied to West Texas Intermediate crude oil.
The bigger question is whether Kalshi users actually adopt these products in meaningful numbers.
Prediction markets remain what the company is best known for, and event contracts covering sports, politics, economics and other real-world events continue to define the Kalshi brand.
But the direction of travel is becoming increasingly clear.
Kalshi built its name through prediction markets. It now wants to become a broader U.S. trading exchange where prediction markets are just one of many products available.
