Cooley ranks #25 in The Law Firms Citation Share Audit 2026, with a Citation Share score of 0.6%. The audit, published by Everything-PR, measures how visible US law firms are inside AI answer engines. Cooley sits at the bottom of the 25-firm field, below DLA Piper at #24 (0.8%) and well behind Kirkland & Ellis, which leads the index at #1 with a score of 14.8%. The index identifies Cooley's strongest category as venture capital and life sciences.
What the Law Firms Citation Share Audit 2026 Measures
The Law Firms Citation Share Audit 2026 modeled five AI engines: ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. Everything-PR ran more than 80 high-intent legal prompts spanning ten BigLaw practice areas: M&A, restructuring, IP litigation, white-collar defense, securities enforcement, antitrust, private equity, capital markets, real estate, and labor and employment. Twenty-five US law firms were scored with equal weighting across the engines. The composite Citation Share score weights five dimensions: citation frequency, cross-engine breadth, query-type breadth, extractability, and crawl access.
Why Cooley Ranks #25
Cooley's 0.6% Citation Share places it last among the 25 firms scored. The index identifies venture capital and life sciences as Cooley's strongest category. That concentration matters for how the audit assigns score. According to the index, Citation Share rewards firms that appear across multiple buyer-intent surfaces, not firms that dominate a single category. A firm anchored in one strength area has fewer query surfaces on which it can accumulate citations across the ten practice areas the audit tests.
The index also names named-deal density as the dominant citation driver. Firms that get named in M&A, restructuring, capital markets, and litigation press at consistent cadence compound citation share through the work itself. This is the mechanism that separates the top of the field from the bottom, and it frames where Cooley's 0.6% sits relative to firms scoring in the double digits.
How Retrieval Mechanics Shape the Field
The Law Firms Citation Share Audit 2026 identifies several structural forces that determine which firms AI engines surface. According to the index, Above the Law has overtaken Chambers as the dominant retrieval anchor because it publishes daily versus Chambers' annual ranking cycle. The index also notes that Wikipedia entity discipline matters: firms with stale, contested, or incomplete Wikipedia entries cede citation share to competitors with cleaner entity coverage.
The index describes the paywall as the silent killer. Content behind Westlaw, LexisNexis, Bloomberg Law's paywall, or law-firm-client-portal infrastructure is invisible to AI engines. The index states that Westlaw and LexisNexis are functionally invisible to AI engines because they are paywalled, making the institutional knowledge layer of American legal practice dark for AI retrieval purposes. It further notes that Cornell LII outranks LexisNexis in AI legal answers because AI engines retrieve free, structured, crawlable content regardless of authority or institutional weight. These mechanics apply across the field and set the conditions under which every firm, Cooley included, accumulates or forgoes citation share.
Where Cooley Sits in the Broader BigLaw Story
The index observes that partner-level coverage compounds at the firm level: a firm with twenty partners holding sustained press footprints produces meaningfully higher citation share than a firm with two partners holding equivalent footprints. Combined with the audit's finding that Citation Share rewards firms appearing across multiple buyer-intent surfaces, this frames the gap between Cooley's 0.6% and the leaders. Kirkland & Ellis tops the index at 14.8%, followed by Wachtell, Lipton, Rosen & Katz at #2 (11.2%) and Cravath, Swaine & Moore at #3 (9.6%).
Cooley's position in the audit reflects a Citation Share of 0.6% across the five AI engines and ten practice areas tested. With venture capital and life sciences identified as its strongest category, Cooley's standing at the next refresh will turn on the citation drivers the index names: cross-surface presence, named-deal density, entity discipline, and content that AI engines can crawl.
