Clear Street LLC

Clear Street LLC (commonly "Clear Street"; parent Clear Street Group Inc.) is a New York–headquartered financial-infrastructure company founded in 2018, with offices at 150 Greenwich Street (4 World Trade Center). It remains privately held. It filed for a Nasdaq IPO under "CLRS" in January 2026, postponed, then formally withdrew the registration statement and listing on February 19, 2026, citing market conditions. Reported headcount is roughly 800–900 employees. Per figures released at its IPO launch, net revenue was approximately $1.04–1.06 billion for 2025, up from $463.6 million in 2024; earlier private rounds valued it at about $2 billion (2023 Series B) and about $12 billion (December 2025 Series C).

Operations. Clear Street describes itself as a cloud-native, end-to-end capital markets platform built on a single real-time ledger. Its broker-dealer business (Clear Street LLC, a FINRA/SIPC member) provides prime brokerage, clearing and custody, securities finance/stock-lending, margin lending, and trade execution across equities and options, plus derivatives and portfolio-management tools. It has expanded into investment banking and equity research, added Canada and UK operations (2023–2024), applied for EU licenses, and announced the acquisition of Hong Kong–based Boom Securities. The company reports roughly 700–900 institutional clients and $16 billion in customer balances.

Litigation posture. Clear Street is an operating company appearing solely as a defendant (0 plaintiff cases, 1 defendant case) — the classic profile of a target, not an asserter.

Tracked case. Cedar Lane Technologies Inc. v. Clear Street LLC (S.D.N.Y., filed 2025-09-22). Cedar Lane is a British Columbia–based non-practicing entity that acquired patents originating largely from Intellectual Ventures and asserts image/AV-processing patents in high-volume campaigns; Unified Patents and Stanford's NPE database classify it as a patent assertion entity. The Clear Street suit sits within a late-2025 wave of Cedar Lane complaints against financial-services firms in S.D.N.Y. (e.g., Bank of New York Mellon, TIAA-CREF, Empire Asset Management), typically brought by Rabicoff Law and often resolved by dismissal or settlement.
