CBO Scores Senate Farm Bill S. 5526 at $4.4B Net Over 10 Years

TL;DR: The Congressional Budget Office (CBO) on October 29, 2026 scored the Senate farm bill (S. 5526) at a net cost of $4.4 billion over 10 years, with a SNAP state cost-share provision adding roughly $1.1 billion per year as the headline driver. Industry insiders now predict another extension rather than lame-duck passage, though Senate Ag Chairman Boozman says a bill still has a "fair chance."

Key takeaway

CBO scored the Senate farm bill at $4.4 billion over 10 years, and insiders now expect another extension over lame-duck passage.

What happened

The Congressional Budget Office released its cost estimate for the Senate farm bill, S. 5526, on October 29, 2026, pegging the net 10-year cost at $4.4 billion. The headline component is a new SNAP state cost-share provision, which CBO estimates adds roughly $1.1 billion per year.

Industry insiders quoted by AgWeb are now predicting that Congress will pass another extension of the existing farm bill rather than move S. 5526 during the lame-duck session. You can track the Senate draft's progress on our Senate status page.

Senate Agriculture Committee Chairman John Boozman said the "Four Corners" negotiators, the top Republicans and Democrats on the House and Senate Ag committees, have been working for weeks, with roughly 10 percent of the bill still unresolved at the staff level. Those unresolved issues are escalating from staff to Senate leadership, specifically Majority Leader Schumer and Minority Leader Thune.

Boozman also said President Trump "really wants to get a farm bill done" and that passage still has a "fair chance." He stated that he opposes another one-year extension of the current law.

What it means

The $4.4 billion score sets the budget baseline lawmakers must work within, and the SNAP state cost-share is the single largest piece. SNAP, the Supplemental Nutrition Assistance Program, is the food-assistance program formerly known as food stamps. A state cost-share would require states to pay a portion of benefit costs now covered fully by the federal government.

Here is how the key numbers break down:

• Net 10-year cost: $4.4 billion (CBO, Oct 29, 2026)
• SNAP state cost-share: roughly $1.1 billion per year
• Unresolved share of the bill: about 10 percent at the staff level

For the audiences most affected, the practical takeaway is uncertainty. Row-crop and specialty growers, ranchers, conservation stakeholders, and crop-insurance participants still do not have final program terms. SNAP recipients and state administrators face a provision that could shift costs to states. See our funding breakdown for how dollars move across titles, and what's new vs. 2018 for the structural changes under debate.

If Congress instead passes an extension, most current programs would continue under existing authority, delaying the title-by-title changes in both H.R. 7567 and S. 5526.

What's next

As of November 2, 2026, the path forward is uncertain. The Senate is scheduled to return from recess on November 9, which compresses the available lame-duck calendar and makes the timeline tight for floor action on S. 5526.

The unresolved roughly 10 percent of the bill is now moving from staff to Senate leadership, so any breakthrough likely depends on Schumer and Thune. Boozman says passage still has a "fair chance" and that he opposes another one-year extension, but insiders quoted by AgWeb expect an extension to be the more likely outcome. Follow developments on our timeline and status page.

If negotiators cannot close the final items before the lame-duck window closes, an extension becomes more probable. Readers who want to weigh in can use our contact Congress tool.

Those issues are now escalating from staff to Senate leadership, specifically Majority Leader Schumer and Minority Leader Thune. The "Four Corners" negotiators, the top members of the House and Senate Ag committees, have been working on the bill for weeks.

Does Chairman Boozman support another farm bill extension?

No. Senate Agriculture Committee Chairman Boozman said he opposes another one-year extension of the existing farm bill.
