Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Interviews target underwriting managers and pricing actuaries at composite and specialty insurers, corporate risk managers and insurance buyers at commercial policyholders, retail and wholesale brokers who place liability programs, and claims executives who see loss development before it reaches public filings. Regulatory affairs contacts at state and national insurance departments are included to track filed rate changes ahead of their effect on written premium. Sampling weights North America and Europe, where liability lines are most standardized and disclosure is richest, while treating Asia Pacific and Latin America contacts as directional given thinner public reporting in several of those markets.

Secondary sources, this report

Desk research draws on NAIC statutory annual statements and state rate and form filings in the United States, Lloyd's market results and syndicate reports, EIOPA insurance statistics and national supervisor bulletins across the European Union, A.M. Best rating reports and Best's Market Segment Reports for major carriers, and SEC 10-K and 10-Q filings for publicly listed insurers that break out liability lines. Where a carrier reports combined ratios or premium by line in its own investor disclosures, that figure is used directly instead of estimated from an industry-wide average.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from claims-cost inflation trends, particularly the effect of higher litigation awards on general and umbrella liability lines, layered against the pace at which cyber and directors and officers coverage move from optional add-ons to standard purchases. Pricing-cycle behavior, whether the market stays in a hardening phase or reverts to broader rate competition, is modeled explicitly instead of held constant. The 2020-2021 pandemic-era disruption to claims frequency is treated as an anomaly and normalized out of the trend line feeding the forecast. For the forecast to hold, claims severity growth needs to continue outpacing general price inflation.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs were back-tested against each region's recorded premium growth for 2020 through 2024 to confirm the model reproduces already-known history before it is trusted going forward. Segment share shifts, particularly the pace at which cyber liability gains share from traditional lines, were checked against carrier line-of-business disclosures instead of accepted on trend alone. Sensitivities were tested on claims severity inflation and on how a shift in the underwriting cycle from hardening to competitive pricing would change premium growth, to confirm the base case does not depend on a single assumption holding exactly.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest in general liability, professional liability and umbrella lines, where regulator filings and public carrier disclosures are dense enough to cross-check directly. It is thinner in cyber liability, where policy wording and reporting conventions still vary enough across carriers that comparing disclosed premium between two insurers is not always a clean like-for-like comparison. The main structural risk to this forecast is a shift in tort law or a wave of rate caps in a major market, either of which would slow claims-cost growth faster than the base case assumes. This report is best read as medium confidence overall.
