Kalshi

Kalshi is a United States-based regulated prediction market exchange that enables users to trade event contracts based on the outcomes of future real-world events. Founded in 2018, Kalshi became the first federally regulated prediction market exchange in the United States after receiving designation as a Designated Contract Market (DCM) from the Commodity Futures Trading Commission (CFTC) in 2020. The platform allows participants to trade binary contracts on events relating to economics, politics, financial markets, weather, sports, technology, and other subjects. Unlike cryptocurrency-based prediction markets, Kalshi settles contracts in U.S. dollars and operates under federal financial regulation.

History

Kalshi was founded in 2018 by Tarek Mansour and Luana Lopes Lara, who sought to create a regulated marketplace for trading directly on the outcomes of future events. The founders argued that while traditional financial markets allowed participants to hedge many forms of risk, there was no regulated exchange dedicated to event-based contracts.

In November 2020, the Commodity Futures Trading Commission designated Kalshi as a Designated Contract Market, making it the first federally regulated exchange in the United States dedicated exclusively to event contracts. The platform launched publicly in 2021.

Since its launch, Kalshi has expanded the range of markets available for trading and has experienced substantial growth in trading volume, particularly during elections, major sporting events, and significant economic announcements.

Objectives

The principal objectives of Kalshi include:

providing a regulated prediction market;
facilitating price discovery for future events;
enabling risk management through event contracts;
supporting information aggregation;
improving forecasting using market-based incentives;
providing transparent financial markets.

Regulation

Kalshi is regulated by the Commodity Futures Trading Commission as a Designated Contract Market under the Commodity Exchange Act. As a regulated exchange, it is required to comply with federal rules governing market integrity, customer protection, surveillance, and risk management.

Its regulatory status distinguishes it from many offshore or cryptocurrency-based prediction markets.

How it works

Kalshi lists markets based on objectively verifiable future events.

Examples include:

economic indicators;
interest rate decisions;
elections;
weather events;
sports competitions;
financial market movements;
public policy outcomes.

Each market generally consists of two outcomes:

Yes
No

Contracts trade between US$0.01 and US$0.99.

The market price represents the implied probability assigned by traders to the occurrence of the event. If the predicted outcome occurs, the corresponding contract settles at US$1.00; otherwise it expires worthless.

Trading

Trading occurs through a continuous electronic order book.

Participants may:

purchase event contracts;
sell contracts before settlement;
hedge existing positions;
speculate on future events.

Prices fluctuate according to supply and demand among market participants rather than being determined by a bookmaker.

Event contracts

Kalshi's primary financial product is the event contract, a binary derivative that pays a fixed amount depending on whether a specified event occurs.

Event contracts have been listed on subjects including:

inflation;
unemployment;
Federal Reserve decisions;
elections;
weather;
sports;
entertainment;
cryptocurrencies;
commodities.

Each contract is settled using publicly verifiable outcome criteria established before trading begins.

Technology

Kalshi operates as a centralized electronic financial exchange.

Its infrastructure includes:

electronic order matching;
market surveillance;
customer identification procedures;
clearing and settlement systems;
risk management controls.

Unlike decentralized prediction markets, Kalshi requires customer identity verification and operates under federal regulatory standards.

Applications

Kalshi is used for:

forecasting;
hedging event-related risks;
speculative trading;
economic research;
market analysis;
probability estimation.

Businesses and investors may use event contracts to hedge exposure to specific economic or political developments.

Advantages

Kalshi provides several benefits.

These include:

federal regulatory oversight;
transparent market pricing;
centralized exchange infrastructure;
U.S. dollar settlement;
standardized contracts;
publicly observable probability estimates.

Its regulated status allows participation by individuals and institutions seeking a federally supervised marketplace.

Challenges

Kalshi has faced several challenges, including:

legal disputes regarding the regulation of prediction markets;
differences between federal and state regulatory approaches;
restrictions on certain categories of event contracts;
public debate over the distinction between prediction markets and gambling.

Several U.S. states have challenged aspects of Kalshi's operations, while the company maintains that its markets fall under exclusive federal jurisdiction through the CFTC.

Relationship with other prediction markets

Platform	Primary characteristics
Kalshi	Federally regulated U.S. prediction market using U.S. dollar settlement
Polymarket	Cryptocurrency-based decentralized prediction market
PredictIt	Academic prediction market operating under a distinct regulatory framework

Kalshi differs from cryptocurrency-based platforms by operating as a federally regulated financial exchange rather than a decentralized blockchain application.

Impact

Kalshi has become one of the leading regulated prediction market exchanges in the United States. By introducing federally regulated event contracts, it expanded the use of market-based forecasting beyond traditional financial assets and contributed to growing interest in prediction markets as tools for price discovery, risk management, and information aggregation. Its regulatory status has also placed it at the center of ongoing legal and policy debates concerning the treatment of prediction markets under U.S. financial and gambling laws.
