What this price means for Illinois Corn farmers
Illinois corn averaged $4.78 per bushel in September 2026, just $0.03 below the US average of $4.81 for the same month. Illinois corn rose from $4.36 in July to $4.55 in August and $4.78 in September, three straight months of gains. Illinois growers sit near river terminals, ethanol plants and feed users, so the competition among buyers keeps the state price close to the national figure. The current marketing-year average (MYA) of $4.15 for 2025 trails the prior year's $4.18 by $0.03, and the current figure may still be preliminary.
The September print of $4.78 and the MYA of $4.15 answer different questions. A forward contract priced off a monthly print locks in that point-in-time price, while the MYA is the better number for budgeting annual revenue because it reflects sales across the whole marketing year. For example, on 10,000 bushels the gap between $4.78 and $4.15 is about $6,300, which is the revenue error a budget carries if it assumes the monthly price lasts all year. Many producers price part of the crop off strong prints and budget the rest conservatively.
