USDA's 181.2 bpa corn yield meets farmer skepticism in Corn Belt survey

USDA's October World Agricultural Supply and Demand Estimates revision put the national corn yield at 181.2 bushels per acre — and an informal text-message survey of farmers across the Corn Belt suggests that number may be too high.

The survey came from a farmer and AgMarket adviser who farms near Charleston in east-central Illinois, a GIB of StoneX. Days after wrapping up his own 2026 harvest, he texted a simple question to several clients: rate your crop from 0 to 5, where 0 is a disaster and 5 is a record. The responses, he concedes, are far from scientific. But the trend they reveal sits uneasily beside USDA's October shocker.

His own operation provides the baseline. He farms ground ranging from very good to average in the Charleston area. The 2026 season was nearly perfect apart from an unseasonably wet June, which dropped 11.5 inches of rain on his home farm in a single month and hurt crops in places.

The corn crop came in 8 to 10 bushels above his actual production history, roughly matching last year and landing 5 to 7 bushels short of a farm record. He rates it a 4 on his own scale. Soybeans followed a similar pattern: a few bushels above APH, a few bushels short of a record, and 5 to 7 bushels better than last year — though that comparison is flattered by a super-dry August that made the 2025 bean crop poor.

What does the survey actually show?

Two findings stand out from the responses he collected.

• Corn: The average score across all corn responses was 3.4 — a crop better than APH but not close to a record. Only one respondent believes they set a record.
• Soybeans: The majority of respondents rated their beans better than their corn, yet only two growers reported records.

The corn number carries the sharper implication. Last year marked the first time the national average corn yield surpassed 180 bushels per acre, at 186.3 bpa. After October's revision, USDA has the crop above 180 bpa for a second consecutive year. To achieve that, national yields do not need to match last year's record, but they need to come close.

A 3.4 average does not suggest closeness. If that score were accurate across all US corn acres — and the adviser is careful to say there is no reason to assume it is — he believes it would be very difficult for the national yield to clear 180 bpa.

The gaps in his sample matter. He received no responses from Minnesota, which appears likely to post high yields this fall, nor from Kansas and Nebraska, which he identifies as the current swing yield states. Without those states, his few responses simply do not scream big corn yields.

How solid is USDA's soybean call?

On soybeans, the picture softens. USDA has been consistent in recent months that bean yields will match or exceed last year's record. His survey agrees with the direction: most respondents scored their beans higher than their corn.

But the magnitude looks questionable. Only two growers set records, which leads him to believe USDA is a touch high on soybean yield — though by a much smaller margin than he suspects on corn. Bean yield is difficult enough to guess that he will not argue the point yet. On the big picture, he sides with USDA: bean yields are better than corn yields this year.

One footnote on the data. On October 23, USDA revised the September yield estimate higher but left the October figure unchanged. That revision moved no markets, since it concerned old data. It simply shortens the bridge between the September and October changes.

What should farmers watch next?

USDA can adjust yield in both the November and December WASDE reports, but the adviser does not expect a major change until January, when final yield numbers are released. Until then, the market must trade its own guess of where that January figure lands.

His money is on the low side. He expects January's final number to come in below the 181.2 bpa from the October report. Growers pricing 2026 grain should treat the November and December reports as positioning windows, and watch Kansas and Nebraska harvest results — the swing states his survey missed — for the truest read on where the January number settles.
