Open tenders from DAE, ISRO and DRDO units, portal by portal
Counts from ScanX's own store of what the portals published. Each row says how that portal is read, because some are read whole and some only in part.
| Portal | Open now | Published since 22 Sept |
|---|---|---|
| GeM | 3,050 | 1,872 |
| Defence eProcurement | 103 | Not counted |
| CPPP | 84 | 60 |
| Buyers' own tender sites | 60 | 31 |
| All portals, each tender once | 3,290 | 1,963 |
How each portal is read
- GeM
- GeM's whole bid feed, read hourly since 22 September 2026. Bids published before then are held in full only for a few departments, so counts of older bids understate the market.
- Defence eProcurement
- Read by closing date: a tender is held in its last seven days. Counted in Open now only.
- CPPP
- A sample: about 250 tenders a weekday from the newest pages of a listing that carried about 31,000 live tenders when counted on 20 August 2026.
- Buyers' own tender sites
- Buyers that publish on their own sites rather than the national portals. Each site's public tender list is read whole, from the day its reader was added in September 2026. Where a site gives no publication date, the hour ScanX first read a tender stands in.
Buyers with the most open tenders
As each portal names the buyer. GeM names the department, Defence eProcurement the head of the unit chain. Buyers read from their own tender sites are counted in the totals, not ranked here.

How these figures were counted
Measured 4 October 2026 at 02:13 IST from the store the collector writes every hour. This page is rebuilt from a new snapshot, and every figure on it moves with the next one.
- Counted by buyer
- Counted by buyer, not by title. A tender counts when the organisation or ministry its portal publishes is the Department of Atomic Energy or one of its units (such as BARC, IGCAR, RRCAT, VECC, NPCIL, the Nuclear Fuel Complex, the Heavy Water Board, Atomic Minerals and UCIL), the Department of Space or an ISRO centre (VSSC, LPSC, Satish Dhawan, URSC, NRSC, ISTRAC, the propulsion complex), or DRDO. Every tender on a DAE buyer's own tender site that ScanX reads counts too. That is everything these buyers publish, works and services included. DRDO is counted here and under defence.

Buyers' own tender sites - Open now
- A closing date after the moment of measurement, on every portal ScanX reads. CPPP state tenders, Defence eProcurement and Defence PSU eProcurement are read by closing date, so a tender there is held only in its last week or two, and their open counts are the tenders closing soonest.
- Published since 22 September 2026
- Only portals that see every new tender count: GeM, CPPP, CPPP ePublishing, CPWD eTender and buyers' own tender sites. The window starts on 22 September 2026, the day ScanX began reading GeM's whole feed, and will grow to 90 days as the store does. CPPP's figure is a sample, as its note above says.
- Days to close
- From the publication date to the closing date as last read, so an extension already published counts. CPWD and some buyers' own sites publish no date, so the hour ScanX first read a tender stands in.
- Counted once
- A procurement listed on two portals counts once in every total, joined on its reference number with case, spacing and punctuation removed. GeM reverse auctions that follow an earlier bid are left out, because only that bid's qualified bidders may take part.
- Not read
- These are counts of what ScanX reads, not of every tender in India. ScanX does not read IREPS, municipal portals or state portals outside GePNIC, and on GeM it reads the listing, not every bid document.
