Interactive Brokers centralizes prediction markets, routing Kalshi, CME and ForecastEx via one trading portal

Interactive Brokers has launched a unified prediction‑market portal that aggregates markets from Kalshi, the CME Group and ForecastEx, allowing clients to access multiple prediction exchanges through a single interface. One report noted Interactive Brokers manages over $800 billion in client assets, underscoring the scale of the brokerage entering consolidated prediction‑market access ^{[1] [2] [3] [4]}.

According to coverage, the portal offers contracts tied to political races, weather events and financial metrics, while entertainment and sporting‑event contracts are not available on the platform. The system employs smart order routing to direct trades to the venue offering the most favorable pricing after accounting for transaction costs, and Kalshi reported that institutional participation on its platform increased roughly eightfold over the prior half‑year ^{[4] [1]}.

Crypto Briefing characterized the consolidation as a development that could significantly enhance market efficiency and accessibility, while other outlets emphasized the technical and venue‑integration aspects of the rollout ^{[5] [2]}.

Coverage across outlets focused on the operational consolidation of prediction‑market venues and noted growing institutional engagement, without introducing new performance or adoption metrics beyond those reported by the platforms and brokers ^{[1] [3] [4]}.
