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

5W's release of The Functional Beverages AI Visibility Index 2026, ranking 25 brands by estimated AI citation share across more than 60 consumer prompts on ChatGPT, Claude, Perplexity, and other platforms, highlights the growing importance of AI-driven conversations in the beverage industry. This means that website owners in the beverage and related sectors need to pay close attention to how their brands are being discussed and represented by AI chatbots, as this can significantly impact their online visibility and reputation. With Celsius winning the chatbot category, it's clear that AI-driven conversations are becoming a key factor in consumer decision-making, and brands that fail to adapt may be left behind. To stay ahead, website owners should track their brand mentions on AI platforms, monitor their llms.txt files to ensure they are not inadvertently blocking valuable AI bot traffic, and optimize their content to align with the types of consumer prompts that are driving AI citations in their industry. By taking these steps, website owners can better navigate the increasingly complex landscape of AI-driven conversations and maintain a strong online presence.
