Does an unsuccessful bidder have the right to know who won?
An unsuccessful bidder has the right to be informed of the fate of its bid and of the identity of the winning company. The buyer generally discloses to an unsuccessful bidder who requests it the winner's name and the characteristics and advantages of the winning bid, under the applicable procurement rules. Knowing who won, and on what terms, is therefore not a favor: it is a right built into procurement rules, in the name of transparency. The reasons for the rejection of your own bid, and how to use them to improve, are covered separately: how to find out why a public-contract bid was rejected.
This right to information serves two purposes for a company: understanding in order to improve on future contracts, and gathering the elements needed if it is considering a challenge to the rejection.
What can you obtain about the winning bid?
On the winning bid, an unsuccessful bidder can obtain, by requesting it, the winner's name and the characteristics and advantages of the winning bid. The buyer does not disclose the competitor's full bid: it discloses the characteristics and advantages that justified its choice, within the limits of trade-secret protection. The company thus learns what made the difference, without accessing the confidential detail of the winning file.
What the buyer discloses answers a precise question: on what elements did the winning bid prevail? The answer clarifies the gap between the unsuccessful bid and the winning one, criterion by criterion.
Where is a contract award made public?
A contract award is made public through an award notice, for contracts subject to this requirement. Beyond the information sent directly to bidders, the buyer publishes, for the relevant contracts, a notice announcing the award: the subject matter, the winner, and details of the contract concluded. These notices appear on the same channels as the original tender notices, for example at national or European level.
Checking award notices also tells you about a contract you did not respond to: who won it, on what scope, which feeds knowledge of a sector and preparation for future tenders.
What routes are there to find out who won, and what does each give you?
Several routes provide information on a contract's outcome. The table below links each route to what it gives you.
| Route | What it gives you | For whom |
|---|---|---|
| Rejection notification | the fact that the bid was rejected | the unsuccessful bidder |
| Request for details | the winner's name, characteristics and advantages of the winning bid | an unsuccessful bidder who requests it |
| Award notice | the winner and data on the contract concluded | anyone interested |
This table shows the gradation: the unsuccessful bidder first receives the reasons, then, on request, details on the winning bid, while the award notice informs more broadly.
When is reading the notice enough, and when should you request details?
To simply learn the outcome of a contract, reading the award notice is enough, and generic AI can help find and summarize these notices. To learn on what terms the winner prevailed, requesting details becomes necessary: the unsuccessful bidder asks for the winner's name and the characteristics of the winning bid, elements that pinpoint the gap. The line is your goal: learning the outcome goes through the notice, learning the detail of the winning bid goes through a request to the buyer.
Finding out who won and on what terms, in order
- Note the rejection notification, which opens the right to information.
- Request details: the winner's name, characteristics and advantages of the winning bid.
- Check the contract's award notice, if one exists.
- Compare criterion by criterion the unsuccessful bid against what made the difference.
- Draw lessons for future tenders.
- Keep the relevant material in case a challenge is considered.
On the Optivalue.ai platform, which publishes this site, 85 specialized agents (72 subject-matter agents, 12 sector-specific agents, 1 librarian agent) link every requirement in the file to the company's own responses, which helps, once the reasons are received, pinpoint the gap with the winning bid.
Frequently asked questions
Does the buyer disclose the winner's full bid?
The buyer does not disclose the winner's full bid: it discloses the characteristics and advantages that justified the choice, within the limits of trade-secret protection. The confidential detail of the winning file is not transmitted.
Do you need to request the details, or are they automatic?
The reasons for rejection are disclosed automatically, and details on the winning bid are generally obtained on request from the unsuccessful bidder. Making this request to the buyer is therefore useful to go beyond the reasons.
Where do you find award notices?
On the same channels as the original tender notices, at national or European level depending on the contract. These notices announce the winner and data on the contract concluded.
Do these rights apply outside France?
The right to information for unsuccessful bidders varies by market. Each country organizes its own transparency around contract award; check the law that applies in the market in question.
