CHICAGO, July 2 (Reuters) - The following are U.S. expectations for the resumption of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CDT (1330 GMT) on Thursday.

WHEAT - Up 3/4 cent to 2 cents per bushel

• Wheat futures rose for a third session, as traders adjusted positions ahead of the federal July 4th holiday, extending gains triggered by the U.S. Department of Agriculture's acreage and stocks estimates on Tuesday.

• USDA estimated 2026 U.S. wheat plantings well below market expectations.

• Net U.S. wheat export sales for 2026/27 were 300,060 metric tons in the week that ended on June 25, the U.S. Department of Agriculture said. Analysts expected 300,000 to 600,000 tons.

• Saudi Arabia issued a tender to purchase 655,000 metric tons of wheat, the General Food Security Authority said on Thursday.

• Statistics Canada on Tuesday pegged Canadian wheat area below trade expectations, adding further support to wheat prices.

• CBOT September soft red winter wheat WU26 was last up 2-1/4 cents to $6.02-1/4 per bushel. K.C. September hard red winter wheat KWU26 was last 2-1/4 cents higher to $6.37-1/4 per bushel, while Minneapolis September spring wheat MWEU26 was last up 1 cent to $6.19-1/2 per bushel.

CORN - Up 1/4-cent to 3 cents per bushel

• Corn extended gains on export demand and spillover support following Tuesday's USDA reports, while traders monitored a heat wave in the U.S. corn belt and Europe.

• Net U.S. corn export sales were 732,070 metric tons for 2025/26 in the week that ended on June 25, the USDA said. Analysts expected 500,000 to 1.1 million tons.

• Meanwhile, weekly new-crop U.S. corn export sales were a net 767,756 metric tons for 2026/27, USDA said. Analysts expected 400,000 to 1.1 million tons.

• Corn continued to see some support from Tuesday's USDA acreage and stocks estimates. The USDA estimated the July 1 quarterly corn stocks lower than analysts' views.

• But gains were capped by ample global supplies and falling oil prices LCOc1, as corn is used for producing biofuels.

• Hot weather hit the U.S. Midwest this week, though widespread showers and easing heat into next week were expected to limit stress on corn and soybean crops.

• CBOT December corn CZ26 was last up 3/4 cent at $4.43 per bushel.

SOYBEANS - Up 3 to 8 cents per bushel

• Soybeans turned higher amid continued rumors of increased Chinese interest in purchasing U.S. soy, and traders adjusting positions ahead of the holiday weekend.

• But news of sluggish weekly exports slumping to a marketing year low for old-crop beans, and no new sales to China, may weigh on prices during the session, one market analyst said.

• U.S. soybean export sales were a net 41,786 metric tons for 2025/26 in the week that ended on June 25, the U.S. Department of Agriculture said. Analysts expected 300,000 to 650,000 tons.

• CBOT November soybeans SX26 were last 6 cents higher to $11.55-1/4 per bushel.
