Clear Street LLC

Clear Street is a financial infrastructure technology company and diversified financial services firm headquartered in New York, NY. Founded in 2016, its mission is to modernize the brokerage ecosystem by providing sophisticated investors with access to every asset in every market through a unified, cloud-native platform built for speed, transparency, and scale.

The company offers a comprehensive suite of financial services, including prime brokerage, multi-asset clearing, secure custody, advanced execution, financing services, and investment banking. Its proprietary cloud-native platform unifies trading, risk management, and financing across various asset classes such as equities, options, futures, fixed income, foreign exchange, and swaps. Clear Street serves a diverse client base that includes sophisticated individuals, hedge funds, proprietary traders, broker-dealers, ETF issuers, family offices, corporate issuers, traditional asset managers, and alternative asset managers.

Clear Street has actively expanded its offerings and global presence in recent years. In April 2024, the firm launched futures clearing and execution services following its acquisition of React Consulting Services and its BASIS platform in July 2023. The company also established an Equity Research Group in November 2024. Ed Tilly serves as the CEO. While Clear Street had filed for an initial public offering, these plans were withdrawn in February 2026 due to market volatility and broader concerns within the fintech sector. The company positions itself as a modern alternative to legacy financial infrastructure, aiming to serve sophisticated investors who are underserved by existing platforms.

Clear Street Opens Institutional Gateway to Kalshi Prediction Markets

Event summary

  • Clear Street has become the first institutional Futures Commission Merchant (FCM) to join Kalshi's exchange and clearing house.
  • The partnership includes clearing, settlement, derivative, block trading, and high/low-touch trading solutions, as well as swap capabilities for prediction market ETFs.
  • Kalshi is the world’s largest prediction market, founded in 2018 and credited with legalizing prediction markets as a financial asset class.
  • Clear Street’s cloud-native platform enables the rollout of new products and services without duplicating technology stacks.

The big picture

This partnership represents a significant step towards the mainstream adoption of prediction markets as a legitimate asset class within institutional portfolios. Kalshi’s regulated exchange, combined with Clear Street’s infrastructure and client base, addresses a key barrier to entry for larger investors seeking exposure to event-based risk and reward. The move validates the growing interest in alternative data and predictive analytics within the financial industry.

What we're watching

Liquidity Impact
The influx of institutional capital through Clear Street will likely increase trading volume and liquidity on Kalshi’s exchange, but the platform’s ability to handle this increased scale remains to be seen.
Regulatory Scrutiny
As prediction markets gain broader institutional acceptance, regulators will likely increase scrutiny of Kalshi’s operations and the broader market structure, potentially impacting future growth.
ETF Adoption
The launch of swap capabilities for prediction market ETFs signals a potential new avenue for investor exposure, and the success of these products will hinge on investor demand and regulatory approvals.
