William R. Berkley founded the company in 1967 in Greenwich, Connecticut, shortly after earning his MBA from Harvard Business School. The original venture, Berkley Dean & Company, was built with modest capital and a clear premise: specialty underwriting done by experts in narrow markets would outperform generalist insurers over time. In 1970 the firm merged with a small Connecticut insurer to gain a licensed underwriting platform, and the company took the W. R. Berkley name.

W. R. Berkley went public in 1973, listing its shares on the New York Stock Exchange. Through the 1970s and 1980s the company expanded methodically, adding regional and specialty units during hard markets when pricing was favorable and pulling back during soft markets. This countercyclical discipline, grow when rates are adequate and shrink when they are not, became a defining trait.

The founding philosophy produced a distinctive structure. Instead of building one large underwriting organization, Berkley kept adding separate units, each focused on a single product line or niche. By the 1990s the company had assembled a portfolio of specialty insurers covering professional liability, surety, commercial transportation, and program administration, alongside regional standard-lines carriers.

International expansion followed in the 1990s and 2000s. The company built or acquired operations in the United Kingdom, Continental Europe, Latin America, and Australia, and it established a presence at Lloyd's of London through Berkley Syndicate 1967. Domestic growth continued through units such as Nautilus Insurance Group, a surplus lines writer acquired in the 1980s, and Carolina Casualty, a commercial trucking insurer.

Under the founder's son, W. Robert Berkley Jr., who became president and chief operating officer in 2009 and CEO in 2015, the company sharpened its specialty focus. Newer units were created rather than bought, including Berkley One, a personal lines insurer for high-net-worth clients launched in 2017. The founder remained chairman into the 2020s before moving to an emeritus role.

The company's growth accelerated after 2020 as commercial insurance pricing hardened. Net premiums written rose from $8.9 billion in 2021 to $12.7 billion in 2025. Fiscal 2025 set company records for gross and net premiums written, pre-tax underwriting income of $1.2 billion, net investment income of $1.4 billion, and net income of $1.78 billion, with a 21.2% return on equity. Book value per share grew 26.7% during 2025 before dividends and share repurchases, reaching $25.72.

W. R. Berkley publishes annual corporate responsibility reporting covering climate risk in its underwriting and investment portfolio, workforce programs, and governance. The company is not a Certified B Corporation and holds no major third-party sustainability certifications; its disclosures are largely self-reported rather than independently certified.

On underwriting, the company has restricted new coal-related business and applies environmental risk criteria in specialty lines. Its investment policy screens for ESG considerations within a fixed-income-heavy portfolio. Community programs are run at the unit level, reflecting the decentralized structure.

W. R. Berkley's public record is comparatively clean for an insurer of its size. The most visible disputes are ordinary-course coverage litigation and regulatory matters common to commercial insurers, including disputes over business interruption and liability claims, none of which has produced a material adverse judgment against the company.

Like all U.S. insurers, its units are regulated at the state level and file extensive statutory reporting. The company has not faced a major fine, fraud finding, or executive misconduct case in recent years. Analysts and rating agencies generally cite management depth and reserve discipline as strengths rather than concerns.
