Horizon Trading Solutions expanded its electronic trading platform to support market making on Kalshi, providing institutional clients native connectivity to the CFTC-regulated prediction market as professional participation in event contracts grows. The expansion reflects rapid institutionalization of prediction markets, which have evolved from niche retail products into an emerging asset class attracting proprietary trading firms, quantitative market makers and liquidity providers. Technology vendors are racing to provide low-latency infrastructure needed to support continuous quoting, automated risk management and high-frequency trading strategies as trading volumes increase.
Horizon Platform Enables Multi-Asset Event Contract Trading
The enhanced platform enables market makers to quote, trade and hedge Kalshi's event-driven contracts alongside traditional financial instruments through a single trading environment. Unlike conventional futures or equity markets, prediction markets require infrastructure capable of handling rapidly changing probabilities, frequent repricing and very short-dated contracts that can resolve within hours or days.
Horizon stated its platform combines native exchange connectivity with low-latency execution, high message throughput, continuous 24/7 operation and integrated risk management designed specifically for these characteristics. The platform allows firms to manage event contracts alongside cash equities and listed derivatives while supporting cross-venue hedging and centralized risk controls.
Kalshi Executive Highlights Institutional Liquidity Growth
Andy Ross, Head of Institutional at Kalshi, stated: "The growth of institutional liquidity is an important milestone in the evolution of event markets. Horizon Trading Solutions' native connectivity helps professional market makers participate more efficiently and deepen liquidity across Kalshi markets."
Prediction markets have become one of the fastest-growing areas of exchange innovation during the past two years. Initially focused on elections and economic releases, regulated event contracts now cover a broad range of financial, political and sporting outcomes. As volumes have increased, institutional firms have begun treating these products more like traditional exchange-traded instruments than speculative novelty markets.
Sylvain Thieullent, Chief Executive Officer of Horizon Trading Solutions, stated: "It is clear that event-driven markets are becoming increasingly important for institutional market participants. 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."
Trading Technologies and Plus500 Previously Added Kalshi Support
Kalshi has increasingly become the focal point of infrastructure expansion. Earlier this year, Trading Technologies announced support for Kalshi's markets through its professional trading platform, giving institutional traders access to regulated event contracts alongside futures and options. Plus500 expanded its U.S. offering by introducing Kalshi-powered sports event contracts, highlighting how brokers are beginning to incorporate prediction markets into their retail product suites.
Technology vendors are focusing less on the contracts themselves and more on providing the execution, connectivity and risk infrastructure required by professional trading firms. For market makers, prediction markets introduce operational challenges that differ from traditional asset classes. Prices represent probabilities rather than valuations, liquidity can shift rapidly as new information emerges, and contracts often expire within days or even hours.
Prediction Markets Require Institutional-Grade Infrastructure
Prediction markets are increasingly being viewed as another electronically traded asset class requiring the same institutional infrastructure available in equities, options and futures. As liquidity providers continue entering the market, competition is shifting toward execution quality, latency, connectivity and risk management rather than simply offering access to event contracts.
For trading technology providers, supporting prediction markets is becoming less about experimentation and more about ensuring clients can participate in a segment that continues to attract growing institutional interest. Horizon's integration positions event contracts alongside more established financial instruments within professional electronic trading workflows.
