Apex Fintech Solutions and Kalshi partner on API technology for prediction markets
Apex Fintech Solutions announced an API partnership with Kalshi on August 13, 2026. The integration lets Apex's brokerage clients offer Kalshi's event contracts without building their own futures commission merchant infrastructure. The platform connects through Apex's AscendOS APIs for order management, market data, and position tracking. Apex provides infrastructure for modern investing and is extending that platform into prediction markets.
Kalshi just removed a major barrier for brokerages that want to list event contracts. Apex's API lets firms plug into Kalshi's markets without building futures commission merchant infrastructure from scratch, cutting months off launch timelines. That turns a niche product into something any brokerage on Apex's rails can switch on quickly.
Robinhood already routes prediction-market volume through Kalshi and its Rothera joint venture; easier API access lets Robinhood deepen that flow or lets competitors like Webull match the offering faster. The cost is dependence: Kalshi's distribution now runs partly through Apex's stack, and any outage or fee change on AscendOS hits every downstream brokerage simultaneously. Rival platforms that want to win brokerage deals must now offer comparable white-glove integration or watch Kalshi lock up the shelf space.
Today's Apex deal gives Kalshi brokerage-ready distribution, pairing with its existing regulatory infrastructure and giving the exchange reach that competitors must now match.
