What Arnold & Porter Kaye Scholer does

The firm delivers an integrated offering across three core service lines — Regulatory, Litigation, and Transactional — supported by a Pro Bono practice that logged 107,000+ hours in 2025, and is structured around five primary verticals: Life Sciences & Healthcare (FDA expertise), Antitrust/Competition, FCA/Government Enforcement, Litigation, and Corporate/Transactional work for multinational corporates.

The firm serves enterprise clients — primarily corporations, financial institutions, and regulated entities — through relationship-led business development by partners and senior attorneys, as well as select sovereign engagements (e.g., the Embassy of Uzbekistan investment climate report in 2025). Revenue is generated entirely through professional fees on matter-by-matter and retainer engagements priced by complexity and partner time; no public fee schedule exists and revenue is not disclosed.

Arnold & Porter's competitive position is anchored by 173 Chambers-ranked lawyers (142 in Chambers USA 2026 across 75 practices), sector-specific regulatory depth, and longstanding Big Law brand recognition. Recent strategic activity (2025–2026) includes lateral hiring, Chambers USA 2026 validation, expansion into stablecoin and digital asset regulatory advisory, and continuous advisories on FDA, UK CMA, and post-midterm energy regulation. The firm has no disclosed AI/technology platform; service delivery is human-expertise-led professional services.
