**Tight U.S. cattle supplies remain the dominant driver of ground beef prices in 2026.** The national beef cow herd stood at approximately 28.5 million head as of July 1, down 1% year-over-year and near multi-decade lows after years of drought-driven liquidation, producing the smallest January 1 inventory since 1951. This has constrained the 2026 calf crop (down 2%) and fed-cattle marketings, with USDA’s October WASDE report lowering beef production forecasts while raising import expectations. Retail ground beef averaged a record $6.92 per pound in August, up roughly 10% from a year earlier, even as increased trimmings imports and modestly higher replacement heifer retention offer limited near-term relief. Trader focus centers on slaughter pace, feed costs, and whether herd rebuilding accelerates enough to ease 2027 supplies.
