U.S. corn futures gained on Tuesday following the release of the U.S. Department of Agriculture's annual acreage report, which indicated American farmers planted fewer acres of corn this year and that on-farm grain stocks were smaller than the market had anticipated.
The USDA said U.S. farmers planted 95.343 million acres of corn in 2026, a decline from 98.788 million acres a year earlier but slightly above the average analyst estimate of 94.992 million acres. The agency's stocks update showed corn inventories on June 1 totaled 5.295 billion bushels, coming in under the average pre-report estimate of 5.408 billion bushels.
Wheat futures rose as the USDA reported all wheat plantings at 42.740 million acres, below the consensus estimate of 43.858 million acres. Soybean futures moved higher in step with corn after the USDA reported soybean plantings of 85.365 million acres, up from 81.215 million in 2025 and in line with trade estimates.
Market participants have faced mixed directional pressures ahead of the report. A favorable start to the U.S. Midwest growing season, strength in the dollar and a decline in oil prices following de-escalation in the Iran war had weighed on corn and soybean values. Those factors contributed to most corn contracts on the Chicago Board of Trade reaching contract lows in the run-up to the USDA release.
Summary
The USDA's annual acreage and stocks data showed lower corn acreage compared with last year but slightly above analyst estimates, tighter-than-expected corn stocks as of June 1, soybean plantings matching estimates and all wheat plantings below forecasts. The report prompted gains in corn, wheat and soybean futures.

Risks and uncertainties
- Weather and crop development - While the Midwest has seen a favorable start to the growing season, future weather conditions could alter yield prospects and influence prices.
- Macro and energy influences - Dollar strength and oil price movements have exerted downward pressure on prices; further shifts in these markets could change crop price momentum.
- Market positioning - Contract lows in corn ahead of the report suggest that market sentiment was already stressed; subsequent volatility may follow as participants reassess supply estimates.
The USDA numbers provided fresh data points for traders and analysts assessing supply balances for the 2026 marketing year. The immediate market reaction reflected a recalibration of expectations based on the combination of acreage and stocks figures.
