The attorney who triumphed over Meta in a significant addiction case claims that AI was his hidden advantage.

      TL;DR: Trial lawyer Mark Lanier leveraged AI to secure a significant $6 million verdict against Meta and Google in a social media addiction lawsuit, likening its utility to having "10 extra workers."

      Mark Lanier, a Texas trial attorney, achieved a groundbreaking $6 million verdict against Meta and Google in March regarding social media addiction, asserting that AI played a crucial role in all aspects of his preparation and performance during the five-week trial. In an interview with Business Insider, Lanier explained that the technology allowed him to condense 30 hours of work into just 10, comparing it to having “10 additional workers who are highly trained, familiar with the case, and available around the clock.” This case marked the first instance of a social media addiction lawsuit reaching a jury verdict in the U.S.

      The jury determined that Meta and Google were negligent, labeling their platforms as “dangerous,” and awarded $3 million in compensatory damages along with $3 million in punitive damages. Meta was assigned 70% responsibility while YouTube was deemed 30% responsible. This case sets a precedent for over 1,500 similar lawsuits currently consolidated in federal multidistrict litigation, potentially influencing the resolution of numerous pending claims against social media companies.

      Lanier and his team employed AI before and during the trial using Boodlebox, a multi-model platform used largely in higher education that provides access to ChatGPT, Claude, and Gemini within a single collaborative environment. He collaborated with the company to develop a custom license, costing six figures annually, that integrated his 42 years of trial experience into the AI's framework. Boodlebox serves over 1,300 colleges and universities and has indicated to Business Insider that it is considering expansion into the enterprise and legal sectors, partly due to its collaboration with Lanier.

      The AI was utilized for both tactical and analytical purposes. After each court day, Lanier's team would input the day’s transcripts into various AI models for assessment. He used AI to rephrase arguments more persuasively for the courtroom. During jury deliberations, the jury's written questions were analyzed with AI to gauge the panel's thought process.

      Each evening, the team gathered in a war room to discuss and allocate tasks, such as identifying the five most crucial documents supporting specific arguments. Much of this work, often involving several of Lanier's daughters, was completed in Boodlebox overnight, enabling Lanier to review their findings with only four hours of sleep before court the next morning. He noted that the team logged thousands of hours on the platform during the case.

      Lanier is judicious about the limits of AI in his practice. He refrains from using it for drafting briefs or conducting legal research without supervision, as these applications have contributed to a rising issue of AI inaccuracies in courts. Legal analyst Damien Charlotin maintains a database documenting over 1,300 cases worldwide where AI-generated documents contained false citations, with reported incidents increasing from around two weekly in early 2025 to two or three daily by late 2025. The prestigious law firm Sullivan & Cromwell even filed an urgent letter in April requesting a bankruptcy judge avoid sanctions after admitting that their court filing contained AI-generated inaccuracies.

      Lanier conceded that AI made an error once during the case by referencing a detail he knew was incorrect. “It’s not unbridled,” he remarked. “You are an important part of the equation.” He views AI as a tool that enhances human judgment rather than replacing it, a critical distinction that some lawyers facing sanctions have overlooked.

      The irony of the situation is notable. Lanier utilized AI, a technology central to the scrutiny facing Meta and other tech firms, to defeat one of the companies developing it. Meta is projected to invest between $125 billion and $145 billion in AI infrastructure in 2026, yet in a Los Angeles courtroom, a trial lawyer armed with a six-figure AI subscription harnessed the same underlying technology to attain a verdict that may shape the outcomes of numerous additional lawsuits against the company.

      Lanier's firm has established a dedicated AI team that provides him with a three-page briefing each Friday detailing advancements in the field. He anticipates that his next trial will make his work in the Meta case “look like Fred Flintstone and the Stone Age.” With 69% of legal professionals now reporting the use of generative AI for work-related tasks, as per industry surveys, the focus has shifted from whether AI will transform litigation to whether lawyers will manage its use responsibly enough to avoid becoming cautionary examples themselves.
