Oat Milk Market Growth & Trends

The global oat milk market size is expected to reach USD 13.72 billion by 2033, registering a CAGR of 16.8% from 2026 to 2033, according to a new report by Grand View Research, Inc. Rising dairy milk allergies and rising interest in plant-based nutrition are primary factors driving the market for oat milk during the forecast period. Growing urban population, rising disposable income, increasing diabetic population globally, and rising concerns regarding food safety are likely to boost the demand for plant-based milk. In addition, the increase in cardiac diseases, diabetes, obesity, and vitamin deficiency is leading to an increase in the demand for plant-based milk, such as oat milk.

In the buoyant plant-based milk space, the demand for oat milk is increasing owing to oats being more sustainable than their counterparts such as almonds, soy, and coconut. Furthermore, the neutral flavor of oat milk and health credentials such as high prebiotic fiber in the product are factors attracting customers towards the consumption of oat milk. Consumers are considering health to be of paramount importance and are shelling out more money on products that offer health benefits along with contributing towards environmental protection, thus benefitting the market growth. Additionally, the mass adoption of vegan and similar diets owing to moral concerns is expected to benefit the growth of the market.

The market will continue to be driven by an increase in milk allergies and lactose-intolerant consumers. With an increasing number of people who suffer from lactose intolerance, beverage manufacturers such as The Coca-Cola Company are also increasingly introducing new oat milk variants to appeal to their respective consumers, further driving oat milk sales. The sale of oat milk through supermarkets and hypermarkets is increasing on account of the visibility for differentiating and understanding the labels of products. Additionally, high penetration of these stores in countries of North America and Europe has contributed towards increased sales of oat milk in these regions.
