Who Owns MyFitnessPal? Not Under Armour, Whatever AI Tells You

MyFitnessPal is owned by Francisco Partners, a private equity firm that bought it from Under Armour in a sale completed on 18 December 2020. Under Armour has not owned it for almost six years.

That is still true as of 16 October 2026. Francisco Partners lists MyFitnessPal as a current investment, and we found no announcement of a sale, although Reuters reported in April that one is being explored. If you are asking who owns MyFitnessPal because an AI chatbot told you Under Armour, the chatbot is out of date. We caught one doing exactly that.

MyFitnessPal ownership timeline

Every row comes from a filing or a statement by one of the companies involved, or from Reuters.

The app itself is run by MyFitnessPal, Inc., based in Austin, Texas, the company named in its terms of service. Under Armour's own filings treat the sale as done: its quarterly report filed in February 2026 says it "collected a $50 million earn-out in connection with the sale of the MyFitnessPal platform" in 2024.

Is MyFitnessPal being sold?

Possibly, but nothing has been agreed in public. Reuters reported, citing four sources, that Francisco Partners is working with JPMorgan on the sale process. Both declined to comment. Exploring a sale is not a sale: until a deal is announced and completed, the owner is Francisco Partners.

What AI says: "UA owns popular fitness-tracking apps"

On 15 October 2026 we ran an AI visibility audit of Nike, Adidas, Puma and Under Armour. Asked "Under Armour vs Nike", Claude (claude-sonnet-5, answering from memory with web access off) listed Under Armour's advantages and wrote:

"Connected fitness (MyFitnessPal, MapMyRun) – UA owns popular fitness-tracking apps, giving it a data/engagement edge Nike doesn't fully match"

Under Armour owns neither app. MyFitnessPal went to Francisco Partners in 2020, and MapMyRun went to Outside Inc. in 2024.

The odd part: the model knew. Asked "who is the CEO of Under Armour", the same model wrote that connected fitness was "largely divested — MyFitnessPal was sold in 2020". Same model, same brand, opposite answers, depending on the question. We found this by reading the answers by hand and checking them against Under Armour's filings.

Why AI repeats an outdated owner

A model answering from memory is bounded by its training data. It cannot look anything up, so nothing published today changes an answer a model gives from memory. That only changes when the vendor ships a new model. An assistant that searches the web while it answers can find the filings. One answering from memory cannot.

A training cutoff does not explain this case, though. The sale happened in 2020, and the model clearly knew about it. One likely reason: Under Armour owned MyFitnessPal for almost six years, so text written in those years describes it as an Under Armour app, because it was one. The correction sits in a handful of filings and press releases. When a question puts Under Armour against Nike, the older association may win.

Nobody outside the model vendors can confirm how a model weighs this, so treat it as a working explanation, not a finding. Strictly, this is an outdated fact rather than an invention. Most people call both "hallucinations", and for the reader the result is the same.

If you own a brand: check what AI says about your portfolio

If you sold a product line, bought a company or changed owners, AI may still describe the old version. Check it:

1. Ask each AI assistant who owns your company and what it owns. Ask inside a comparison too ("your brand vs your biggest rival"). That is where Claude got it wrong.
2. Check every answer against a primary source: your filings and your own press releases.
3. State the current fact on your own site, in plain text. Assistants that search can find it. Memory answers wait for the next model.
4. Write down the date and the model, then re-check after each model update. An undated check can't be compared with the next one.

More cases like this one, each checked against a source, are in our AI hallucination examples.
