Red Bull Won the Cooler. Celsius Won the Chatbot. A $152B Category Fragmented by Benefit, Not by Volume.

MIAMI, July 13, 2026 /PRNewswire/ — 5W, the AI Communications Firm, today released The Functional Beverages AI Visibility Index 2026 — ranking the 25 brands by estimated AI citation share across more than 60 consumer prompts on ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews.

Celsius leads with an estimated 13% AI citation share. Red Bull follows at an estimated ~11%, Liquid Death at ~8.5%, Olipop at ~7.5%, and Poppi at ~6.5%. The global functional-beverage market is estimated at ~$152 billion in 2025.

Why it matters: Almost no one types “best energy drink” into a chatbot anymore. Buyers ask for “healthy energy,” “gut-health soda,” “clean caffeine.” Those queries route to brands built on a benefit narrative — not the brands built on shelf volume.

Three findings:

Five brands hit billion-dollar valuations in a single year. Olipop, Poppi, Liquid Death, Alani Nu, and Ghost — and the engines noticed every one.

Prebiotic soda grew an estimated 245% in tracked U.S. channels between 2022 and 2024 — and the citation surface followed.

Celsius bridges both worlds. Energy positioning + fitness narrative + the estimated $1.65 billion Alani Nu acquisition = the most-cited brand in the category.

“Red Bull and Monster won the cooler. That war is over and they won it. But the question moved — and the brands that own the new question are the ones AI repeats. Citation share follows the function, not the volume.” — Ronn Torossian, Founder & Chairman, 5W
