RecompetedNobody Is Reading SAM on September 29
We pulled every Department of Defense justification notice SAM.gov will serve, 10,000 of them, and counted them by the day they posted. An ordinary business day carries twelve. September 29 carried 49 last year and 45 this year, the two tallest days in twenty months, and strip out DLA's parts notices and the top five days are all in the same week.
Pull every sole-source justification the Department of Defense has posted to SAM since February of last year, sort the days by volume, and the same calendar date lands on top twice.
September 29, 2025: 49 notices. September 29, 2026: 45.
Nothing else in twenty months comes close (chart below).
That is 435 business days and 5,485 DoD justification notices, pulled this morning off SAM's search API at full depth, 10,000 records across every agency, then cut to the records whose top-level organization is the Department of Defense.
Twelve Is a Normal Day
The baseline barely moves. The median business day over the whole twenty months carries 12 DoD justifications, and the median in non-September months is also 12.
Federal holidays go to zero, cleanly: Labor Day, Columbus Day, Christmas, New Year's Day, the Fourth.
So the series is flat, all year, for twenty months. And then the last week of the fiscal year roughly triples it.
The last five business days of FY2025 carried 180 notices. The last five of FY2026 carried 148.
Against a median week of about 60, that is a year's worth of sole-source paper arriving in the five days when your own shop is closing out its fiscal year.
Strip Out the Valves
The obvious objection is DLA. Roughly four in ten DoD justifications in any ordinary month are Defense Logistics Agency parts notices, and a hydraulic coupling J&A is not a capture event.
The objection fails, and it fails in the interesting direction. DLA's share of the four peak days is 34.6%, below its 43.5% share of ordinary days.
The surge is disproportionately everybody else.
Drop DLA entirely and an ordinary business day carries 7 non-DLA DoD justifications. Here are the five busiest non-DLA days in the entire record:
- September 29, 2025: 32
- September 29, 2026: 32
- September 30, 2025: 28
- September 24, 2025: 25
- October 1, 2025: 21
Five for five inside the September 24 to October 1 seam. The sixth is an ordinary Wednesday in March 2025 with 19.
Why the 29th
This is a posting clock, not an awarding clock, and the distinction is the whole mechanism.
FAR 6.305(a) gives an agency 14 days after contract award to make the justification publicly available, and the only place it has to go is SAM. A 30-day window applies to the unusual-and-compelling-urgency awards under 6.302-2, and a brand-name justification under 6.302-1(c) posts with the solicitation instead.
So the September 29 wall is not a day on which the Pentagon made 45 sole-source decisions. It is the paper trailing an obligation rush that already happened, landing inside its statutory window, on the last business days anyone is at a desk.
Here is the catch, and it is 6.305(d)(3): the justification "must remain posted for a minimum of 30 days." A minimum is not a guarantee.
The thing you did not read on September 29 is not reliably there in December.
What Posted While You Were Closing
The September 29, 2026 board is not a parts list. DISA posted three cloud justifications in one day (852675395 USTRANSCOM Government Cloud, 852675771 NORAD & USNORTHCOM, 852675435 CMRS Cloud). SOCOM posted two air traffic control justifications, H9225726CE003 and H9225726DE002. Military Sealift Command posted three exceptions to fair opportunity. DCSA justified its Bloomberg Anywhere licenses.
One of them sits on our own expiring board. SP3300-20-F-1300 is DLA's EDC Modernization delivery order to Advantaged Solutions, $286,659,200.33 obligated, running to September 23, 2027. At 3:13pm Eastern on September 29 the agency posted its intent to modify it sole-source again under FAR 6.302-1, for "additional software development due to design gaps, and additional OCM support."
That is the fourth justification notice on that single order in fourteen months: August 2025, October 2025, March 2026, and now September 29. Two of the four landed in a fiscal-year seam.
A $287M services order gets re-justified twice a year and the notice that tells you so arrives on the busiest paper day of the year.
Final Thoughts
The practical lever here is 4 CFR 21.2(a)(2): a protest has to be filed not later than 10 days after the basis is known or should have been known, whichever is earlier. For work that went sole-source, the posting is frequently the first public moment that basis exists.
"Should have been known" is doing quiet work in that sentence when 45 notices land on one afternoon.
We would not call September 29 a hiding place. The incentive is duller than that, and more reliable: the award rush sets the clock, the clock sets the posting date, and the posting date lands where attention is thinnest.
Two years running, that has been the same date in late September, a Monday once and a Tuesday once.
Put a calendar reminder on the last three business days of September and the first two of October, and read the justification feed on those five days specifically. It is the cheapest standing item you will add to your pipeline process this year.
Thanks for reading.
