Key takeaways

UCHICAGO ARGONNE, LLC received $81,138,891.00 from the Department of Energy on October 15, 2026, award DEAC0206CH11357.
The action covers the performance based contract for management and operation of Argonne National Laboratory, per the USAspending record.
The amount was the largest single contract action in the week of October 9 to 15, 2026, ahead of every NASA, Treasury, and Veterans Affairs action in the same file.

What the record says, line by line

One order quietly took more than any other contract action that week. The line most summaries skipped is the purpose written into the record itself: performance based contract for management and operation of Argonne National Laboratory, listed as a modification. Argonne is a Department of Energy national laboratory, and the contract to run it sits with UCHICAGO ARGONNE, LLC under award DEAC0206CH11357.

The Department of Energy obligated $86,580,351.98 across 36 contract transactions in the October 9 to 15 window, per the Ledger contractors file. This single $81,138,891.00 action accounts for most of that department total for the week. That concentration is the story: a laboratory management contract is not a purchase of goods, it is funding for the operation of a federal research site for the period the modification covers.

How this compares with the rest of the week

The next largest actions that week were a $76,117,128.00 NASA delivery order and two United States Mint silver orders near 32.8 million dollars each. Readers who follow the Money Trail daily saw different names on Friday and Saturday. Today the trail leads to a laboratory in Illinois funded through the Energy Department.

Sources and methodology

Methodology. Daily cash figures are from the U.S. Treasury’s Daily Treasury Statement (DTS) for September 28, 2026, the government’s official daily cash-flow report. The DTS records money actually moving in and out of Treasury accounts; it is not the same as the budget deficit, which is measured monthly on an accrual-adjusted basis.
