OpenAI is building a legal AI business from scratch, hiring a former lawyer and startup founder to take on Anthropic and a crop of startups valued at $11 billion in one of enterprise software's fastest-growing markets.
OpenAI hired Jason Boehmig, a former Big Law attorney who founded contract-management company Ironclad, to lead a new legal vertical team — signaling the $852 billion company's most direct push yet into software for lawyers. The move comes as law firms face pressure from clients to move faster and in-house legal teams look to automate work they once sent to outside counsel.
"Jason's hire reflects the value OpenAI sees in the legal space," Dan Springer, Ironclad's chief executive, said in an email.
Boehmig, who joined in June, has already recruited Stacey Wang from Ironclad to lead industry marketing for legal and professional services. The team is working with Sherwin Wu, who runs engineering for B2B Verticals at OpenAI's platform business. On Wednesday, OpenAI announced a collaboration with Willkie Farr & Gallagher to roll out ChatGPT Enterprise to every attorney at the white-shoe firm and integrate OpenAI's models into the firm's proprietary tools, including five existing Wendell applications.
The move thrusts OpenAI into a legal AI market that drew $2.1 billion in venture funding in the first half of 2026, per Crunchbase. Harvey, an early OpenAI portfolio company that now serves more than 100,000 legal professionals at an $11 billion valuation, faces a potential competitor in its own backer. Anthropic released Claude for Legal in May, sending shares of Thomson Reuters, Relx, and Wolters Kluwer sharply lower.
A New Competitive Dynamic
OpenAI's legal push follows a playbook the company is deploying across multiple industries. It has built a desktop application for software engineers, introduced secure tools for clinicians, and hired former investment bankers to train its systems for Wall Street. The company has filed paperwork to go public and wants to show investors that ChatGPT can become a platform where knowledge workers do their jobs, not just a chatbot.
The question of what OpenAI builds is existential for legal startups. A tool that combs contracts for risks threatens businesses built around contract analysis, while a broader bundle of legal skills strikes closer to Harvey's territory. OpenAI was an early Harvey investor, and Chief Executive Sam Altman has described the company as a foundation for others to build on. "We see a future where intelligence is a utility like electricity or water," he said at a BlackRock event in March.
Anthropic has already moved aggressively into the category. In January, the rival lab released a legal work plugin that could analyze contracts and track compliance. In May, it launched Claude for Legal, a library of plugins aimed at law firms and in-house counsel. The products target the grunt work of the profession: finding cases, reviewing contracts, and routing documents.
Lawyers Already Use ChatGPT
A Law360 survey found that 54% of attorneys use ChatGPT, ahead of Microsoft Copilot, Gemini, Harvey, and Claude. In-house legal teams sit inside companies where ChatGPT or Claude is already used by engineers and customer support, creating a natural pull for adoption.
OpenAI has also been staffing to answer whether its models are good enough for legal work. In April, the company hired a former corporate attorney as a legal evaluations specialist. AI labs use such evaluations to measure how well systems perform on real-world tasks, ensuring each new version improves.
For now, little is known about what OpenAI will build. A job posting for a founding software engineer states the company aims to "transform legal workflows, improve access to information, and enable legal professionals and organizations to work more effectively." OpenAI declined to comment.
Harvey's founder and Chief Executive Winston Weinberg said he welcomes the competition. "Every new entrant helps Harvey by drawing more attention to legal AI," he told Business Insider. His message for OpenAI: "Welcome to the party."
OpenAI shares, which trade in private markets at a valuation of $852 billion, have no direct public ticker. But the legal AI push pressures publicly traded incumbents: Thomson Reuters trades at 28 times forward earnings, Relx at 31 times, and Wolters Kluwer at 27 times. If OpenAI captures meaningful legal workflow share, those multiples could compress. For legal tech startups, the risk is existential — a platform shift from model provider to application builder could turn a key investor into a direct competitor.
