Olipop

Olipop is the most proven prebiotic soda, with $400 million annual sales and profitability since early 2024. It raised $50 million in Series C funding in February 2025 at a $1.85 billion valuation, giving it the deepest capital base in the category. Its Lemon Ginger flavor scored 9.5/10 from Sporked with just 2 grams of sugar per can—the lowest single-flavor count in this list. This sugar level outperforms #2 Poppi’s typical 5 grams, while its twelve-flavor range dwarfs Simply Pop’s five-flavor debut. Olipop’s wide distribution and early-mover status make it the benchmark that rivals are measured against.
