A holding company whose filing states one total across an insurance business and a family of mostly manufacturing businesses it does not count, so the two are split by description with a flag.
The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.
What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 27% now, 41% at the end of 2027, 48% at the end of 2028, 50% at the end of 2030. By the patterns, the work is about 50% desk work, 18% people work and 32% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 50% of the working time stays with people (conversation, in-person and hands-on work), 42% becomes checking a model's work and 6% could be handed over with lighter checks, from the industries' own figures, not the company's roles.

The filing: “At December 31, 2025, Markel Group and its family of businesses employed approximately 22,900 associates.”
The workforce as industry patterns
| Pattern | Share | Reason, from the filing |
|---|---|---|
| Manufacturing | 55% | By description (c): Markel Ventures (31% of revenue) is a family of mostly manufacturing businesses with consumer and service businesses beside them, counted by no breakdown, so the larger part of the workforce is read at the manufacturing sector, the narrowest level the filing supports. |
| Insurance Carriers | 45% | By revenue (c): the insurance and reinsurance operations (51% of revenue) are read at insurance carriers at 45%, since the filing counts no segment. |

- “There is increasing focus by traditional insurance industry participants, technology companies, insurtech start-up companies, and others on using technology and innovation, including artificial intelligence, to simplify and improve the customer experience, increase efficiencies, redesign products, alter business models, and effect other potentially disruptive changes in the insurance industry.”
- “For example, competitors that deploy artificial intelligence and advanced analytics at scale, or that have access to data sets we cannot use for legal or practical reasons, may achieve superior underwriting, claims, and expense outcomes.”
- “We may not be successful in these efforts, and even if we are successful, they may increase or create the following risks, among others: demand for new products or expansion into new markets may not meet our expectations; new products and expansion into new markets may increase or change our risk exposures, and the data and models we use to manage those exposures may not be as effective as thos...”
