Paris, July 9, 2026 – Horizon Trading Solutions, a global leader in electronic trading solutions and algorithmic technology for capital markets, today announced expanded capabilities for market making on Kalshi, providing its institutional clients with native connectivity to the leading CFTC-regulated prediction market.

As institutional adoption of event-driven contracts continues to accelerate, market makers require resilient, low-latency infrastructure capable of supporting continuous trading, high message volumes, and sophisticated risk management.

Horizon’s electronic trading platform enables market makers, liquidity providers and proprietary trading firms to quote, trade, and hedge event contracts alongside cash equities and listed derivatives.

The platform is designed to address the unique characteristics of event markets, including rapid repricing, probability-based quoting, and cross-venue risk management. It combines low-latency execution, high message throughput, continuous 24/7 operation and monitoring, and integrated risk management to help firms efficiently manage liquidity and exposure.

“The growth of institutional liquidity is an important milestone in the evolution of event markets,” said Andy Ross, Head of Institutional, Kalshi. “Horizon Trading Solutions’ native connectivity helps professional market makers participate more efficiently and deepen liquidity across Kalshi markets.”

“It is clear that event-driven markets are becoming increasingly important for institutional market participants,” said Sylvain Thieullent, CEO, Horizon Trading Solutions. “We are enabling market makers to provide liquidity on Kalshi with institutional-grade infrastructure that scales with growing demand while addressing the unique challenges of event contracts, including pricing, risk management, and hedging very short-dated exposures.”

The enhanced capabilities are available immediately to both existing and new Horizon Trading Solutions clients.
