Whey protein concentrate prices rose sharply through July 2026 before falling in the US to the $8–9-per-pound range in early November. Cheese plants continue to produce whey, but limited ultrafiltration capacity has constrained production of high-protein powders while demand for protein-rich products remains strong.
Processing bottlenecks can limit high-protein whey availability even when raw whey is plentiful, supporting prices for concentrated products. The recent US price decline and mixed demand temper the near-term price outlook.
