What can this research establish—and what remains uncertain?

The evidence supports an active, capitalised supplier category with real purchasing and a wide range of commercial offers. It does not support a precise US market total or guaranteed commercial impact.

This report prioritised original transaction datasets, company announcements, official pricing documentation and regulatory filings. Supplier claims are identified as such. Prices are public observations rather than signed quotes; product capabilities were not independently tested. Published market forecasts, customer labels and survey findings retain their original geographical and methodological limitations.

The next research pass should prioritise buyer invoices and contract samples, US revenue allocation, paid-customer definitions, renewal behaviour and implementation outcomes. Those would improve the market estimate more than another collection of supplier valuations.
