Interactive Brokers has launched a new trading feature that brings together multiple US prediction market platforms into a single interface, allowing clients to access and trade contracts tied to real-world events without switching between accounts.

Unified Access Across Exchanges

According to Thursday's announcement, the broker now connects its clients to Kalshi, CME Group, and ForecastEx through one integrated system. The new platform aggregates similar contracts into a single view, enabling users to search, compare, and trade across venues in real time.

The initial rollout covers contracts linked to elections, economic indicators, and climate-related events. These instruments allow traders to take positions based on the outcome of specific real-world developments.

“Prediction markets are reshaping how investors think about risk and uncertainty,” said Milan Galik, Chief Executive Officer of Interactive Brokers. He added that the company aims to provide access to multiple venues through a single platform, similar to how clients trade traditional assets.

Industry participants pointed to growing demand for these products. Kalshi CEO Tarek Mansour said the integration reflects increasing institutional interest, while CME Group Chairman Terry Duffy noted rising retail participation in prediction market trading.

Meanwhile, Tradeweb earlier took a more institutional route into prediction markets by striking a strategic partnership and taking a minority stake in Kalshi, aiming to plug event data and eventually trading directly into its existing rates and credit marketplaces.

This is positioned as the first institutional‑focused framework for standardized event contracts around macro releases, Fed policy and elections, effectively treating prediction markets as another signal and product set inside core fixed‑income and derivatives workflows.

Publicly-listed FOREX.com, via its parent StoneX, has also focused more narrowly on themed access, partnering with Kalshi to offer clients trading on US election outcomes through Kalshi’s event‑based markets.

Meanwhile, Interactive Brokers (U.K.) Limited more than doubled its pre-tax profit to £34 million in 2025, up from £13.6 million a year earlier, as the FCA-regulated unit continued to add clients and grow trading activity, according to a Companies House filing.

After-tax profit rose to £26 million from £10.5 million, while turnover, driven entirely by commissions on order execution, increased 28% to £46.2 million.
