Wet weather slowed corn and soybean planting, with USDA reporting record slow corn planting for the mid-May window. Grain futures rose after a planting rally, and soybeans gained after funds held a record bearish position.

Delayed planting and possible switching to soybeans tighten the outlook for corn supply, supporting prices, while tariff aid could shift acreage between crops.
