The Global Commercial Seaweed Market was valued at USD 72.3 billion in 2025 and is estimated to grow at a CAGR of 6.9% to reach USD 142.6 billion by 2035.
The market continues to gain momentum as seaweed becomes increasingly integrated into multiple value chains, supported by its functional versatility and sustainability profile. Demand growth is strongly linked to the rising use of seaweed-derived hydrocolloids that perform essential binding, stabilizing, and thickening functions across food, cosmetics, and industrial formulations. These applications collectively account for more than 40% of global commercial seaweed revenue. At the same time, the transition toward environmentally responsible agricultural practices is accelerating the adoption of seaweed-based inputs, positioning seaweed as a natural solution aligned with regenerative and low-impact farming models. Global policy alignment with sustainable agriculture has further strengthened demand. In parallel, innovation across seaweed biotechnology is expanding the market’s value potential, as producers invest in advanced processing to extract high-value compounds for nutrition, health, and specialty applications. These developments are reshaping the commercial seaweed industry from a volume-driven sector into a technology-enabled, high-value ecosystem with diversified end uses and strong long-term growth visibility.
The red algae segment held a 48.6% share in 2025 and is expected to grow at a CAGR of 6.8% through 2035. This dominance is supported by its widespread use in hydrocolloid production, which remains a foundational input across food, pharmaceutical, and personal care manufacturing, reinforcing steady global demand.
The food & beverage applications segment held 33.9% share in 2025 and is forecast to grow at a CAGR of 6.8% from 2026 to 2035. Seaweed continues to be widely incorporated as a natural functional ingredient, supporting formulation stability, nutritional enhancement, and clean-label positioning across packaged and processed food categories.
North America Commercial Seaweed Market accounted for 11% share in 2025 and is showing rapid growth. The region benefits from increasing investment in sustainable aquaculture, climate-aligned materials, and alternative feed solutions, driving broader commercial adoption and downstream innovation.
Key companies operating in the Global Commercial Seaweed Market include Cargill, Tate & Lyle, DuPont, FMC Corporation, Algaia, Gelymar, Acadian Seaplants, Irish Seaweeds, KIMICA Corporation, Qingdao Seawin Biotech Group, Ocean Harvest Technology, Seasol, Seaweed Energy Solutions, Indo Alginate, TBK Manufacturing Corporation, W Hydrocolloids, Inc., MCPI, Mara Seaweed, Qingdao Gather Great Ocean Algae Industry Group, and Shaanxi Hongda Phytochemistry. Companies in the Global Commercial Seaweed Market are strengthening their market position by expanding vertically across cultivation, processing, and formulation to secure supply consistency and improve margins. Significant investment is directed toward research and development to unlock high-value extracts and improve processing efficiency. Strategic partnerships with food, agriculture, and wellness manufacturers are helping accelerate commercialization and application development. Firms are also scaling production capacity in high-growth regions to reduce logistics costs and meet rising demand.
