Contracts signed and value contracted under each, January to August 2026. These are the deepest codes with data beneath this one, so the branches between are skipped rather than walked.

Portugal publishes its complete contract register as open data, so this is counted rather than estimated. January to August 2026. The count and the value cover every procedure type; the bid figures cover open procedures only, because in a direct award the buyer chooses who bids. 19 of them published a bidder list, with a median of 2. A mean is published from 10 open procedures up and a single-bid share from 30, so a rate on this page always rests on enough of them to mean something. All 26 divisions ranked.

France publishes its essential procurement data, the DECP, with the number of offers received on every marché, a field its own schema makes mandatory. January to July 2026, Two things to read alongside the figures: the amount is the notified amount, which for a framework agreement is the ceiling rather than the spend; and the bid figures exclude marchés passed without publicity or competition, where a single offer is the design of the procedure. 1,138 competed marchés declared their offers here, 6.2 on average; the median is shown because an allotted marché repeats the whole consultation's offer count on each lot, which inflates a mean and leaves the median alone. Same bars as Portugal: a mean from 10 procedures, a single-offer share from 30. Buyers are named from their SIRET through the public company register. The French barometer and its method.

The EU Official Journal carries the same measurement for every member state: eForms requires the count of submissions received on every contract award notice. 9.2% of the 173 lots awarded under this code across the Union drew a single bid, and the median lot drew 5. Above the EU thresholds only, and the lot is the unit because one notice can award many. Where EU tenders draw a single bid.
