Interactive Brokers Unites Kalshi, CME on New Platform

Interactive Brokers announced on May 14, 2026, the launch of a new unified interface for trading across multiple prediction and derivatives markets. The platform integrates event contracts from Kalshi, futures from CME Group, and new markets from ForecastEx. This move consolidates access for the brokerage’s more than 2.5 million clients, allowing them to trade diverse instruments, from economic outcomes to traditional commodities, through a single portal.

What Are Event and Prediction Markets?

Prediction markets allow participants to trade on the outcome of future events. These venues transform forecasts into tradable assets, where the price of a contract reflects the market's perceived probability of an event occurring. A contract might pay out $1 if an event happens and $0 if it does not, with its price fluctuating between those values as new information becomes available.

Kalshi is a prominent example, operating as the first event contracts exchange fully regulated by the U.S. Commodity Futures Trading Commission (CFTC). It offers markets on topics ranging from economic data releases to climate metrics. The total value of the regulated prediction market space, while growing, remains a niche segment compared to traditional finance, with open interest often measured in the tens of millions of dollars.

In contrast, CME Group is a global derivatives titan, with an average daily volume that exceeded 23 million contracts in 2025. The integration connects Kalshi's novel, event-driven products with CME's established futures and options markets, creating a broader spectrum of trading opportunities within one ecosystem.

Why Is Interactive Brokers Unifying These Exchanges?

The primary driver for this integration is the simplification of market access and the consolidation of liquidity. Previously, traders interested in both traditional derivatives and event contracts had to manage separate accounts and interfaces. This fragmentation created operational friction and made it difficult to execute cross-market strategies efficiently. By unifying these venues, Interactive Brokers aims to reduce these barriers.

This strategy targets a growing demographic of sophisticated retail and institutional traders seeking to diversify their strategies beyond conventional equities and bonds. The brokerage reported a 21% year-over-year increase in customer accounts in its latest quarterly filing, indicating a strong demand for broader market access. The unified platform is designed to capture and retain this expanding client base.

the inclusion of ForecastEx, a new market operator, suggests an effort to get ahead of innovation in the space. By supporting emerging platforms alongside established giants like CME, Interactive Brokers positions itself as a comprehensive hub for speculative and hedging instruments, from S&P 500 futures to contracts on specific political outcomes.

How Does This Integration Impact Traders?

The most immediate benefit for traders is enhanced efficiency and capital management. With a single interface, users can view real-time data, place orders, and monitor positions across all three exchanges without switching platforms. This allows for more effective portfolio oversight and simplifies the process of allocating capital between different types of risk.

For example, a trader could hedge a portfolio of energy stocks on CME with event contracts on Kalshi related to OPEC production quotas or specific climate-related events. This type of integrated strategy was previously cumbersome to execute. The platform aims to make such sophisticated approaches more accessible to its user base of over 2.5 million traders.

The primary risk, however, involves the inherent complexity of event contracts. Unlike traditional assets, their pricing is based on probabilistic outcomes, which can be difficult to model. The CFTC has historically rejected certain contracts it deemed contrary to the public interest, highlighting the ongoing regulatory scrutiny of these markets. Traders must understand the unique risks and low liquidity profiles of many prediction markets.

What Are the Technical and Regulatory Hurdles?

Integrating three distinct market structures into one front-end presents significant technical challenges. CME, Kalshi, and ForecastEx operate on different technology stacks with unique API protocols and data formats. Interactive Brokers had to invest heavily in building a middleware layer that could normalize data and order flow, a project that likely took more than 18 months to complete.

On the regulatory front, the landscape for event contracts is still evolving. The CFTC's approval of Kalshi set a precedent, but the agency continues to evaluate new products on a case-by-case basis. In 2023, it denied a proposal for contracts based on U.S. election outcomes, citing concerns that they constituted gaming. This demonstrates a clear boundary that platforms and traders must respect.

This unified platform must therefore incorporate strong compliance checks to ensure that only permissible products are offered to U.S. clients. The system must be capable of dynamically adapting to regulatory changes, which adds a layer of ongoing operational complexity and cost for the brokerage. More information on market regulation can provide context on these challenges.

Q: Does the new Interactive Brokers interface support automated trading?

A: Yes, the unified platform is expected to support automated trading via Interactive Brokers' proprietary API. This allows traders to deploy algorithmic strategies across all three integrated exchanges—CME, Kalshi, and ForecastEx. However, traders will need to account for the different liquidity profiles and trading hours of each market, as event contracts often have lower volume than major CME futures, which could impact execution for automated systems.

Q: What types of new events can be traded via ForecastEx?

A: ForecastEx is positioned to offer specialized event contracts in areas not currently covered by Kalshi, such as technological milestones, scientific discoveries, and corporate events like product launch dates. For example, a market could be created on whether a specific technology company will receive regulatory approval for a new device by a certain date. These markets cater to traders with domain-specific expertise, expanding beyond the economic and political events common on other platforms.

Bottom Line

Interactive Brokers' new platform consolidates derivatives and event contract trading, aiming to streamline access and attract sophisticated traders to a growing market niche.
