Domestic corn production in the US - Data and Analysis (1980-2032)

Domestic corn production in the US is expected to remain historically elevated in 2026, at about 15.82 billion bushels, even as output slips 5.6% from the prior year's bumper harvest. Mixed growing conditions lie behind this pullback, with some states enjoying near-ideal weather while others contend with erratic rainfall and temperature swings, but widespread use of advanced seed genetics and precision farming keeps yield potential high across the Corn Belt.Through 2026, production has showcased both the sector's resilience and its exposure to weather shocks, growing at a modest 1.0% compound annual rate while oscillating from a low of 13.65 billion to the record high of 16.8 billion bushels. Output jumped in 2021 as strong prices, export demand and ethanol consumption encouraged farmers to expand planted area under excellent growing conditions. Severe drought in 2022 then dragged production sharply lower, particularly in heavyweight states like Iowa, Illinois and Nebraska, before improved weather and technology-driven yield gains powered a dramatic rebound in 2023. Government conservation programs continued to shape planting decisions at the margins, but consistently strong feed and biofuel demand helped anchor acreage and ultimately pushed production to a record high in 2025, even as prices stabilized.
