Across 37795 tenders, 67% received exactly one bid. That is a measure of entry conditions, not a verdict on any buyer or supplier: a single bid can reflect a narrow specialist market, contract terms, timing, or the cost of preparing an offer. For companies deciding where to spend bid effort, the useful signal is the split by contract size. Smaller opportunities attract fewer competing offers, while larger ones bring more bidders. A repeat win or a single bid is not evidence of impropriety; it is a market condition that can arise from how an opportunity is packaged and advertised. The figures describe tenders and bids received, not awarded value.
Single-bid tenders are common overall
The overall result points to a broad participation problem rather than a finding about individual procurements. With 67% of 37795 tenders receiving exactly one bid, many opportunities may be reaching only one viable supplier, or only one supplier may be choosing to submit. Those are different commercial situations: limited supply, demanding specifications, eligibility requirements, short preparation periods and contract economics can all affect entry. For bidders, the relevant question is not whether a single-bid outcome is improper. It is whether the opportunity offers a workable route to competition, and whether the cost of preparing an offer matches the likely return.
Competition improves as contract size increases
The chart’s central pattern is a sharp difference between smaller and larger contract-size bands. Exactly one bid occurred in 83% of the cheapest quarter and 76% of the middle half, compared with 34% of the most expensive quarter. The median also changes: it is 1 bid in the cheaper bands and 6 bids in the most expensive quarter. The most expensive tenth has a 36% single-bid share but a median of 1 bid, showing that these measures capture different features of competition. Large opportunities can attract more bidders overall without making every tender competitive.
| Contract size | Single bid | Median bids | Measured |
|---|---|---|---|
| Cheapest quarter | 83% | 1 | 9,448 |
| Middle half | 76% | 1 | 18,898 |
| Most expensive quarter | 34% | 6 | 9,449 |
| Most expensive tenth | 36% | 1 | 3,780 |
Buyer counts point to where market access can be tested
The listed buyer totals show that single-bid exposure is not confined to one type of institution. Instituto Nacional de formación Técnico Profesional records 1269 single-bid tenders, followed by Hospital Ramón de Lara FFAA with 435 and Instituto Nacional de Recursos Hidráulicos with 417. Hospital Pediátrico Dr. Hugo De Mendoza records 400, while Hospital Materno Dr. Reynaldo Almanzar records 397. These counts do not establish wrongdoing, and they do not show awarded value. They identify places where suppliers can examine recurring requirements, qualification rules, contract packaging and notice periods. The size pattern suggests that larger packages may draw more competition, while smaller tenders need especially careful market testing.
WHY IT MATTERS
Contract size is linked to the number of competing offers. Suppliers assessing market access should distinguish a single-bid outcome from evidence of impropriety and examine how each buyer packages, qualifies and times its tenders.
