USDA's June 30 Acreage report put 2026 U.S. corn plantings at 95.343 million acres, slightly above March intentions and contrary to expectations of a cut. Soybean plantings rose to 85.365 million acres, nearly matching analyst estimates, while quarterly grain stocks came in tighter than anticipated and grain futures closed higher.
Corn acreage above expectations is bearish on its own, but tighter stocks offset it, leaving weather as the main price driver. Traders expect near-term softness in corn into early August.
After 770 past neutral report events, CORN moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
After 563 past neutral report events, SOY moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), and -0.1% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
The June 30 Acreage and Stocks reports showed tighter-than-expected stocks and a rally in grain futures, contributing to the price jump.
