The strongest public evidence supports several distinct measurements—not one reconciled US enterprise software total. The table preserves each publisher’s definition, measurement period and forecast status. (verdantix.com)
| Publisher and evidence date | Geography and scope | Historical/base-year estimate | Forecast | How buyers should use it |
|---|---|---|---|---|
| Verdantix, 15 July 2026 | Global GRC software; model uses disclosed and calculated vendor revenues | Over $6.5bn in 2025 | $10.9bn in 2031; 9% CAGR | A software-specific category reference, not US expenditure. (verdantix.com) |
| MarketsandMarkets, September 2026 | US eGRC; includes solutions and services | $5.45bn in 2025 | $10.17bn in 2030; 13.3% CAGR | A US estimate, but not software-only or restricted to this desk’s buyer segment. (marketsandmarkets.com) |
| Grand View Research, undated live databook, checked 28 October 2026 | US eGRC; software and services | $17.3304bn in 2025; $19.4099bn estimated for 2026 | $40.5251bn in 2033; 11.1% CAGR for 2026–2033 | A materially broader-valued market model; the 2026 figure remains an estimate.

Why can a US estimate exceed a global software estimate?
Because these are not demonstrably the same market. Services alone do not reconcile the difference: Grand View reports a 75.4% US software share for 2025. Applying that share to its total produces an approximately $13.07bn implied software estimate, a desk calculation rather than a separately published measurement. (grandviewresearch.com)
That result is still above Verdantix’s global software estimate. Our inference is that taxonomy and modelling differences are material, not that US expenditure exceeds worldwide expenditure. Public summaries do not provide a sufficient vendor-by-vendor reconciliation. (verdantix.com)
Do not average the estimates. An average would have no coherent geography, product boundary or services treatment.
Can the desk publish its previous $4–7bn US software estimate?
Not as a verified market measurement. The supplied desk materials describe that number as a working assumption. This research has not established an independently reproducible bridge from the published markets to US software expenditure by organisations in the target employee range.
For external publication, use an attributed, explicitly scoped estimate from the table—or state that the narrower segment remains unmeasured. The same restriction applies to the supplied segment estimates for integrated GRC, IT risk, third-party risk and internal audit: they should not be added together or promoted to measured facts.
