企业律师的商业影响力在近年显著扩大。根据 Thomson Reuters Institute 的行业报告，自 2019 年以来，美国最大的 100 家律师事务所每名律师利润增长 54%，而小时费率上涨速度超过同期通胀的 两倍。顶级律所通过服务私募股权行业获取稳定收入：律师从基金设立、交易结构到债务重组几乎参与全部流程，通常只不直接决定价格。单个客户贡献巨大，例如 Kirkland & Ellis 在过去 两年仅从 Blackstone 获得约 2 亿美元收入，显示大型律所能够在并购、融资和重组周期中持续获利。
尽管商业成功显著，律所的组织结构变化极小。监管限制使公开上市或出售给私募股权几乎不可行，因此改革主要是渐进式的，例如减少按资历分配利润、引入没有所有权的“薪资合伙人”。行业流动性仍然有限：虽然跨律所跳槽有所增加，但创建新律所仍极为罕见。相比之下，美国 10 家领先并购财务顾问中有 3 家成立于本世纪，而最赚钱的律所几乎没有新进入者。这种结构稳定性使顶级律所长期保持高利润与行业地位。
人工智能目前反而强化了律师需求。大型 AI 投资与新型融资结构产生大量合同与合规文件，同时也带来密集诉讼。例如 Anthropic 起诉美国政府，而 OpenAI 面临来自 Elon Musk、The New York Times 以及用户家属的多起诉讼，并在伊利诺伊州被指控无证执业（公司均否认不当行为）。AI 还可能增加纠纷数量：例如一名前 Nippon Life 员工利用 AI 生成投诉，使公司处理成本达到 30 万美元。随着聊天机器人降低法律知识门槛、法院审理仍然缓慢，企业在诉讼增加时仍必须雇佣专业律师。
Corporate lawyers have significantly expanded their commercial power in recent years. According to an industry report by the Thomson Reuters Institute, profits per lawyer at the 100 largest American law firms have increased 54% since 2019, while hourly billing rates have risen at more than twice the pace of inflation. Elite firms earn steady income by serving private-equity clients, with lawyers involved in nearly every stage of deals—from fund formation and transaction structuring to debt restructurings—typically negotiating everything except price. Individual clients can generate enormous revenue; for example, Kirkland & Ellis collected about $200 million from Blackstone alone over the past two years, illustrating how major firms profit across mergers, financing and restructuring cycles.
Despite this commercial success, the organizational structure of law firms has changed very little. Regulation discourages radical moves such as public listings or sales to private equity, so reforms remain incremental. Some firms have reduced purely seniority-based pay and introduced salaried partners who hold titles and billing power but lack ownership. Industry mobility also remains limited: although lateral moves between firms have increased slightly, founding new firms is still rare. Among America’s 10 leading financial advisers for mergers, 3 were founded this century, yet virtually none of the most profitable law firms are new entrants, reinforcing the long-term dominance and profitability of established firms.
Artificial intelligence is currently strengthening rather than weakening demand for lawyers. Massive AI investment and novel financing structures generate extensive contracts and compliance work, while litigation surrounding the technology is expanding. Anthropic has sued the American government, and OpenAI faces lawsuits from Elon Musk, The New York Times and families of users, as well as an accusation in Illinois of practicing law without a license, all of which it denies. AI may also increase disputes: a former Nippon Life employee allegedly generated complaints with AI that cost the insurer $300,000 to process. As chatbots lower the barrier to basic legal knowledge while courts remain slow, rising litigation is likely to keep corporations reliant on professional lawyers.
