Is Kalshi investing? What prediction markets actually are

Facts verified September 13, 2026 against CFTC.gov, federal court opinions and financial press coverage · by FinanzaX Decide. This date is specific to this article, independent of the site-wide pricing and FINRA data verification date shown elsewhere.

Kalshi keeps coming up in the same conversations as Acorns, Robinhood, Webull and Betterment, and it is not on our comparator. That is a deliberate scope decision, not an oversight. The reason is specific, and it starts with what Kalshi actually is, how it is regulated, and the real, unresolved legal fight currently working its way toward the Supreme Court over part of its business.

This is not financial or legal advice. It is a factual explanation of a regulated product and a summary of active, unresolved litigation, not a prediction of how any court will rule. See our full disclaimer.

What Kalshi actually is

Kalshi is an exchange for event contracts: you buy a contract that pays a fixed amount if a specific, defined event happens, and nothing if it does not. The event can be almost anything with a clear yes-or-no resolution, from which candidate wins an election, to whether a government inflation report comes in above a certain number, to the outcome of a sports game. You are not buying a share of a company, and there is no dividend, no ownership stake and no long-term compounding to speak of; the contract simply resolves to its final value once the event happens.

Kalshi's regulated product is built for U.S. residents: trading requires being 18 or older and a resident of the United States, and its standard payment methods, ACH bank transfer, PayPal and Venmo, are U.S.-only. Kalshi does not hold a license in any other country, so trading activity from abroad falls outside the CFTC framework this entire article describes.

The company was founded in 2018 by MIT graduates Tarek Mansour and Luana Lopes Lara, and it grew quickly once regulators approved it. By early 2026, Kalshi had raised over $1 billion in a funding round led by Coatue Management that valued the company at $22 billion, roughly double the $11 billion valuation it carried just three months earlier, in December 2025.

How it is regulated, and why that is different from the four apps we compare

Acorns, Robinhood, Webull and Betterment operate as broker-dealers, registered with the Securities and Exchange Commission (SEC) and FINRA, the framework built for buying and selling securities like stocks and ETFs. Kalshi is not registered with either. In November 2020, the Commodity Futures Trading Commission (CFTC) approved Kalshi as a Designated Contract Market (DCM), the first ever authorized specifically to list event contracts, and it operates under that framework today.

A DCM is a different regulatory category entirely, built for derivatives and commodities trading rather than securities. Per the CFTC's own description, event contracts "are typically structured as swaps" that "derive their value from an underlying commodity," in this case the outcome of an event, and prediction markets in general have existed under CFTC oversight since 2004. The agency's own rules place real limits on what can be listed this way: CFTC Regulation 40.11 specifically prohibits event contracts tied to terrorism, assassination, war, or an activity that is unlawful gaming under state or federal law. That specific rule sits at the center of the legal dispute below.

The open legal fight over sports event contracts

In 2025, Kalshi expanded into event contracts on sports outcomes, and several states pushed back, arguing this is sports betting regulated under their own gambling laws, not a federally supervised derivative. Kalshi's position is that a CFTC-registered DCM's contracts are governed by the federal Commodity Exchange Act (CEA), which preempts conflicting state law. Two federal appeals courts have now ruled on that exact question, and they disagree.

On April 6, 2026, the Third Circuit Court of Appeals sided with Kalshi in a case brought by New Jersey, ruling 2-1 that sports event contracts qualify as federally regulated swaps and that the CEA preempts the state's gambling law. On August 28, 2026, the Ninth Circuit ruled the opposite way in a case brought by Nevada, unanimously siding with the state and rejecting Kalshi's preemption argument, a ruling that also covered event contracts offered by Robinhood and Crypto.com. That direct disagreement between two federal circuits is a real circuit split, not just two similar cases pending at the same time.

Both sides have since asked the Supreme Court to weigh in. New Jersey petitioned on September 2, 2026, seeking to overturn the Third Circuit's ruling, and Robinhood petitioned on September 9, 2026, seeking review of the Ninth Circuit's ruling against it. Neither petition has been granted or denied as of the date verified above, and lower courts in at least two more circuits have reached conflicting results of their own, so the underlying question, whether federal law or state gambling law governs sports event contracts, remains genuinely open. Nothing here predicts how it will resolve.

Robinhood, one of the four apps compared on this site, is itself a party to this litigation over its own separate event-contracts product, a detail worth stating plainly. Its FINRA-registered brokerage business, the one covered in the rest of this comparator, is a distinct part of the company from the event-contracts offering caught up in this dispute.

Why Kalshi is not in our comparator

This site's investing-apps comparator, quiz and growth calculator are all built around one specific question: which broker-dealer or robo-advisor should you open an account with to buy stocks and ETFs. Every axis we score on, per-trade fees, account minimums, round-ups, automatic rebalancing, tax-loss harvesting, assumes a product where you own a security whose value can compound over years. None of that maps onto a Kalshi contract, which resolves to a fixed payout once a specific event occurs and is not designed to be held as a long-term investment. Comparing "which one has the better fee schedule" only makes sense within one product category at a time, and event contracts are a different category from brokerage accounts, not a better or worse version of the same thing.

Leaving Kalshi out is a scope decision about what this specific tool answers, not a judgment on whether prediction markets are a good or bad idea. If you are deciding where to open a brokerage account for stocks and ETFs, our quiz and comparator cover that question directly.
