Apex Fintech Solutions has launched a solution for brokers and fintech companies that are looking to expand their product sets with event contracts.
The new API-based service allows them to offer Kalshi’s event contracts inside their own trading interfaces without building their own Futures Commission Merchant (FCM) infrastructure or direct exchange connectivity.
Tastytrade is the first firm to go live on the infrastructure. The brokerage, which IG Group owns, now offers CFTC-regulated event contracts across areas including commodities, crypto, economic data and financial markets.
The launch also comes shortly after IG agreed to acquire Underdog, a U.S. daily fantasy sports and prediction-markets operator, in a deal worth up to about $1.3 billion.
That makes tastytrade’s early use of Apex’s Kalshi integration part of a wider push by its parent company into event-based trading.
From Separate Venues to Broker Platforms
Event contracts are regulated derivatives, so they cannot be dropped into a brokerage app in the same way as a new stock or ETF feed.
A broker has a long operational checklist that includes tasks such as connecting customers to the exchange via the appropriate futures infrastructure, managing product eligibility and disclosures, and reflecting contract positions and settlements within their existing account experience.
Apex is covering much of that infrastructure tasks. Kalshi remains the regulated marketplace where contracts are traded, while Apex provides the connection between Kalshi and the broker’s platform, along with the back-office functions needed to support customer accounts.

The broker still has to decide how to present the product, which customers can access it, and how it fits into its own compliance and client-support processes.
The service runs through Apex’s AscendOS APIs. In practice, that means a broker can add event contracts inside its own interface. At the same time, customers see those positions alongside other assets, including stocks and options, rather than being sent to a separate prediction market app.
“Investors want to trade on direct events, not proxies,” said Travis McGhee, Global Head of Digital Markets at Apex Fintech Solutions. “Through our platform, clients can now offer Kalshi’s event contracts with ease.”
A Distribution Channel for Event Contracts
The timing reflects growing interest in prediction markets across the retail trading industry. Bernstein has projected that annual prediction-market volumes could approach $1 trillion by 2030, although that forecast depends on regulatory clarity.
The model also gives Kalshi a route to reach broker customers without requiring each platform to build direct event-contract infrastructure from scratch.
For Apex, the service adds another product category to its clearing and custody stack as brokers look to expand beyond equities, options, and crypto.
The company says it provides infrastructure for close to 200 firms, including Webull, eToro US, Stash and Ally Invest. That gives the company a potential distribution channel across a large broker and fintech client base.
Kalshi is the first venue available through the service and Apex plans to add others if there is enough demand.
