December 2026 Chicago corn futures finished at 444.25 cents a bushel, up 0.40% after trading as low as 438.50 cents. StoneX raised its US corn production forecast by 88 million bushels to 16.203 billion, with yield at 183.1 bushels per acre, which is 169 million bushels above USDA's October estimate.
A private forecast well above the USDA baseline signals more potential supply, which is bearish for feed corn prices, though strong demand estimates limit the downside on ending stocks.
After 1,102 past bearish report events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.8% to +1.3%), and +0.0% over 20.
