Corn - Field: Market Size & Forecast 2026

The global field corn market reached approximately USD 270 billion in 2025 (base year), measured as farm-gate value of roughly 1.18 billion metric tonnes produced across 195 million harvested hectares. The market operates in a structurally oversupplied state entering 2026, with USDA projecting record 2025 U.S. production of 15.3 billion bushels and global ending stocks climbing to 309 million metric tonnes for 2026/27, down only modestly from the prior year. The 2.2 percent CAGR through 2032 reflects a mature commodity cycle where ethanol demand provides a structural floor, livestock feed absorbs roughly 58 percent of supply, and weather-driven yield volatility dominates price action more than any structural demand growth narrative. > **Analyst Take.** The market consensus fixates on weather risk as the dominant price driver, which is correct for quarterly moves but wrong for the 2026-20
