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. The audit scored 25 US law firms 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 Sidley Austin Ranks #11
Sidley Austin's #11 position, with a score of 4.2, places it in the upper-middle tier of the 25 firms scored in the audit. The audit lists securities and healthcare as Sidley's strongest categories.
The audit notes that Citation Share rewards firms that appear across multiple buyer-intent surfaces, not firms that dominate a single category. It also identifies 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.
Sidley's own announcements reflect activity across several of these deal categories. The firm reported representing South32 in its aluminum value chain sale to Alcoa valued up to US$5.6 billion, Bio-Techne in its US$11.3 billion acquisition by Merck KGaA, Yum China Holdings in its US$1.2 billion acquisition of the Pizza Hut brand in mainland China, and Hiab in the US$1.035 billion acquisition of Labrie Environmental Group. Sidley also reported representing GFH as anchor investor in the US$5 billion dual IPO of Pershing Square Inc. and Pershing Square USA.
How Extractability and Crawl Access Shape Citation Share
Two of the five scoring dimensions, extractability and crawl access, turn on whether AI engines can reach and parse a firm's content. The audit calls the paywall the silent killer: content behind Westlaw, LexisNexis, Bloomberg Law's paywall, or law-firm-client-portal infrastructure is invisible to AI engines. It observes that Westlaw and LexisNexis are functionally invisible to AI engines because they are paywalled, and that Cornell LII outranks LexisNexis in AI legal answers because AI engines retrieve free, structured, crawlable content regardless of authority or institutional weight.
The audit also finds that Above the Law has overtaken Chambers as the dominant retrieval anchor because it publishes daily versus Chambers' annual ranking cycle. Sidley reported being highly ranked in Chambers USA 2026 on June 4, 2026.
Sidley publishes free, crawlable content through channels including The Sidley Podcast and its insights library, with recent items covering how stablecoins could transform payments and finance and the sweeping SEC rules proposed for public companies. The firm also maintains the Sidley AI Monitor, a centralized resource of content related to AI including Sidley thought leadership and access to its AI lawyers.

Sidley reported electing a new partnership class of 52 on June 1, 2026, and its insights include Brian Fahrney discussing law firm leadership and Sidley's global growth on The Non-Billable Podcast, dated June 30, 2026.
The audit also notes that Wikipedia entity discipline matters, with firms holding stale, contested, or incomplete entries ceding citation share to competitors with cleaner entity coverage.
Sidley describes itself as a global law firm collaborating across disciplines and borders to help clients in more than 70 countries achieve business objectives. For the 15th consecutive year, Sidley was named a LearningElite organization by Chief Learning Officer magazine, and it states it is the only law firm among the 2025 honorees.
