Quinn Emanuel Urquhart & Sullivan ranks #16 in The Law Firms Citation Share Audit 2026, with a Citation Share score of 2.7. The audit measures how frequently and how broadly US law firms are surfaced by AI answer engines across high-intent legal queries. Quinn Emanuel sits just below Weil, Gotshal & Manges (#15, 2.9) and just above WilmerHale (#17, 2.4), placing it in the middle tier of the 25 firms scored.
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, across 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 & employment. 25 US law firms were scored with equal weighting across the engines. The composite score weights five dimensions: citation frequency, cross-engine breadth, query-type breadth, extractability, and crawl access.
Why Quinn Emanuel Ranks #16
Quinn Emanuel's strongest category in the audit is plaintiff-side litigation. That concentration is consistent with the firm's own positioning: Quinn Emanuel Urquhart & Sullivan describes itself as a 1300+ attorney business litigation firm with 33 offices around the globe, each devoted solely to business litigation and arbitration, and its site describes the firm as the largest law firm in the world devoted solely to business litigation and arbitration.
The audit notes that Citation Share rewards firms that appear across multiple buyer-intent surfaces, not firms that dominate a single category. A #16 score of 2.7 reflects a footprint that is present but not spread evenly across the ten practice areas the audit prompts against. Firms concentrated in one strong category capture citation share in that lane while ceding ground in others.
The audit also identifies named-deal density as the dominant citation driver, stating that firms that get named in M&A, restructuring, capital markets, and litigation press at consistent cadence compound citation share through the work itself. Quinn Emanuel's public record shows a steady cadence of litigation outcomes, including a decisive win in a data center fight, a High Court ruling in the Cisco case that narrowed ATS litigation against corporations, a critical patent ruling secured for The Broad Institute, Inc, and a dismissal in a Colorado case against an IVF test provider. These are the kinds of litigation press moments the audit describes as compounding citation share through the work itself.
How Retrieval Mechanics Shape the Score
Several structural findings in the audit bear on where any firm lands. The audit reports that Above the Law has overtaken Chambers as the dominant retrieval anchor because it publishes daily versus Chambers' annual ranking cycle.
The audit also flags that the paywall is the silent killer: content behind Westlaw, LexisNexis, Bloomberg Law's paywall, or law-firm-client-portal infrastructure is invisible to AI engines. Firms whose most substantive coverage sits behind paywalls or client-portal walls surface less often in AI answers. The audit adds that Wikipedia entity discipline matters, noting that firms with stale, contested, or incomplete Wikipedia entries cede citation share to competitors with cleaner entity coverage.
A further pattern the audit describes is 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. Quinn Emanuel names individual attorneys in its public commentary, including Andy Schapiro on a High Court campaign finance decision and Michael Carlinsky on financial news, the kind of partner-level footprints the audit ties to firm-level citation share.
Where Quinn Emanuel Sits in the Broader BigLaw Story
At #16 with a score of 2.7, Quinn Emanuel sits well behind the leaders of The Law Firms Citation Share Audit 2026: Kirkland & Ellis at #1 (14.8), Wachtell, Lipton, Rosen & Katz at #2 (11.2), and Cravath, Swaine & Moore at #3 (9.6). The audit's central finding, that Citation Share rewards firms appearing across multiple buyer-intent surfaces rather than firms that dominate a single category, helps explain why a firm with a defined strongest category in plaintiff-side litigation lands in the middle tier rather than the top.
The audit's mechanics reward consistent, crawlable, cross-practice coverage. Quinn Emanuel's 2.7 reflects a firm with clear litigation strength and a steady record of notable victories, positioned in the middle of the 25-firm field going into the next refresh. Whether that position moves will depend on the factors the audit measures: citation frequency, cross-engine breadth, query-type breadth, extractability, and crawl access.
