Is Wilson Sonsini profitable in 2025?

Yes. Profits per equity partner rose 21.1% to approximately $3.7 million in FY2025, on record gross revenue of about $1.6 to $1.65 billion, up roughly 15% year over year, reported by American Lawyer on March 31, 2026.

Could AI replace Wilson Sonsini's lawyers?

Unlikely for core work. High-stakes M&A negotiation, litigation, and SEC filings require licensed attorneys who carry liability, a moat AI can't cross. The firm even sold its own AI compliance-document subsidiary, SixFifty, to Paychex on July 30, 2025, rather than build a legal-AI product business.

Who is Wilson Sonsini's biggest competitor in venture capital law?

Cooley, which held the #1 spot for most active VC-representing law firm for six straight years through March 2026, and Gunderson Dettmer, which had 1,375 VC deals in 2024 versus WSGR's 861, per PitchBook data cited March 2025.

Is Wilson Sonsini laying off staff?

Attorney headcount fell 5.6% year over year in the 2025 ranking cycle even as gross revenue rose about 15% to a record $1.6 to $1.65 billion, suggesting AI is absorbing associate-level work rather than mass layoffs, per data through 2025 to 2026.

Who owns Wilson Sonsini Goodrich & Rosati?

It is a privately held law firm partnership, not a publicly traded company; U.S. law firm ownership rules generally bar outside equity investment. It sold its tech subsidiary SixFifty to Paychex for an estimated $70 to $85 million, finalized July 30, 2025.

What is Wilson Sonsini's revenue for 2025?

Hard to displace

Assessed 23 July 2026 · Evidence as of 23 July 2026

Strong structural protection; the business model survives ai pressure.

On the recordSince 23 July 2026 · Checkable from March 2027 · Every call on the record Checkpoint: FY2026 revenue results, first full year under new leadership (Hashemi/Baier), will show if AI-driven growth continues

The call

Revenue and partner profits hit records even as headcount shrinks and rivals pull ahead in venture deal volume, a firm growing on fewer people doing higher-stakes work.

Wilson Sonsini is a major law firm that helps companies with deals, stock offerings, and court fights. It's hard to replace because only licensed lawyers can do this work and sign official documents, and the firm has built deep relationships over 60 years, but AI tools are starting to do the routine paperwork that junior lawyers used to do. The big question is whether the firm can change how it pays partners and charges clients fast enough, because right now it is making more money while hiring fewer junior lawyers, which could squeeze the path for young lawyers trying to become partners.

Why

AI pressure: AI-native legal drafting tools (e.g. Harvey). AI absorbs routine contract review and diligence hours, shrinking associate work even as senior deal and litigation demand keeps rising. Could AI do the core job? Unlikely.

Bigger players: Cooley and Gunderson Dettmer. Cooley led VC financings for a sixth straight year with 1,343 deals to WSGR's 861 in 2024; Gunderson has outpaced WSGR since 2011. Could a giant copy it? Probably.

What protects it. Only licensed attorneys can sign SEC filings, carry malpractice liability, or argue in court, work AI and non-lawyer platforms cannot legally take.

What would change this call

PitchBook's next annual VC counsel rankings show Wilson Sonsini's deal count vs Cooley and Gunderson Dettmer. Would show whether WSGR keeps losing VC financing market share to these two rivals.
Wilson Sonsini's FY2026 revenue and headcount figures (due around March 2027). Would show if AI-driven revenue growth continues or if headcount cuts outpace revenue gains.
Partner departure reports in the 12 months after Hashemi and Baier take over as leaders in August 2026. Would show whether the leadership transition triggers attrition or destabilizes the firm.
