| Tradeweb Markets

Dedicated Kalshi pricing now live on Tradeweb for U.S. institutional clients

Kalshi’s American Power Index (KPOW) coming to Tradeweb in July

NEW YORK--(BUSINESS WIRE)--Jun. 24, 2026-- Tradeweb Markets Inc. (Nasdaq: TW), a global leader in electronic trading across asset classes, today announced the launch of a dedicated Kalshi pricing page on the Tradeweb platform, giving U.S. institutional clients access to key event contract data alongside the existing tools and information they use to analyze markets and manage risk.

The launch marks the first phase of Tradeweb’s previously announced strategic partnership with Kalshi and comes as investors increasingly seek additional sources of information to navigate market volatility, geopolitical uncertainty and rapidly evolving market conditions. Tradeweb is also a minority investor in Kalshi.

The new pricing page enables Tradeweb clients to monitor real-time market-implied probabilities across a range of political, economic, financial and global events directly within their existing workflows. It also allows users to build customized watchlists and monitor market expectations alongside Tradeweb’s existing data, analytics and execution capabilities.

The pricing page will also soon incorporate Kalshi’s American Power Index (KPOW), a real-time, market-implied gauge of U.S. political and policy risk. KPOW distills a variety of shifting market-implied probabilities across the presidency, the House and the Senate into a single, continuously updated signal of the macro and event risk that can move rates, credit and equity markets.

Troy Dixon, Managing Director, Co-Head of Global Markets, Tradeweb, said: "As prediction markets mature, they’ve become a real-time gauge of how investors price risk across the global economy. Our clients want access to that signal within the workflows they already use. Integrating Kalshi's data into Tradeweb places it alongside the data, analytics and execution tools clients rely on every day to manage and transfer risk.”

Andy Ross, Head of Institutional, Kalshi, said: “Investors want to trade on real events, not proxies. Integrating prediction market data into one of the world's leading regulated, multi-asset institutional trading platforms is an important step toward more accurately pricing the future.”

Tradeweb and Kalshi are continuing to explore adding capabilities as part of their broader partnership, including expanding access to prediction market data and integrating those insights more deeply into the Tradeweb platform. The companies plan to co-develop new institutional-grade analytics, using both Kalshi’s event probabilities and Tradeweb’s existing pricing, liquidity and macro-intelligence datasets. These analytics will allow institutional participants to analyze unique market signals including new forecasting, risk management and pricing models and incorporate them into trading strategies.

Tradeweb and Kalshi are also exploring the possibility of an institutional-focused platform for event contracts, combining Tradeweb’s central role in macro risk trading and expertise in market design with Kalshi’s preeminent depth across macroeconomic and policy outcomes.
