Nobody owns hydration.

Both halves of that sentence are true, and founders keep hearing only the first one.

The room is real. Circana data reported by BevNET puts powder and mix growth at twice the rate of liquid beverages over the past four years. Powdered hydration specifically did $1.5 billion, up 20% in 2024 — a fourth consecutive double-digit year. Meanwhile sports drinks, the liquid incumbent, did $11.8 billion at +1.8%, with volume actually down 0.2%. That growth was price, not consumption.

And the ceiling is real too. BevNET reports LMNT, Liquid I.V. and DryWater each clearing $100 million, with Liquid I.V. close to $900 million — big enough that it would be the third-largest hydration drink in America if it came in bottles. Circana had it at $924 million, up nearly 28% in the 52 weeks to May 2025.

Here is the part that should stop anyone modelling a Liquid I.V. outcome. The gap to second place is not a gap you close with better minerals, and we know its size because Unilever's CEO said it on an earnings call.

In the same statement he named exactly what is happening underneath: “our share has been a bit under pressure due to a new wave of market entrants that have reduced our share of assortment in the category.” Not a demand problem — a shelf-space problem, caused by everyone arriving at once.

This is the part people skip. Choosing a moment is a workshop exercise. Owning one means showing up in that moment repeatedly, building the community that lives there, and spending against it long enough that the association holds without you present.

DripDrop has been working on the sick day since 2008 — and if you count Dolhun's clinical work in the field, since 1993. That's the actual timeline on owning a moment.

Notice what the chart doesn't say. Years spent is necessary, not sufficient — Pedialyte has had the adult hangover for eleven years and, as the ad data below shows, currently says nothing about it. Time gives you the chance to build the association. It doesn't build it for you.
