The Gym Chain That Wants to Be Your First Call After the Doctor
Planet Fitness reported immense success with its new members-only Perks partnership with telehealth platform Ro, which offers GLP-1 prescriptions. CEO Colleen Keating called it the most successful program in Planet Fitness history, citing strong downloads and conversion rates. That is not a small claim for a company running nearly 2,900 locations. It is also the clearest signal yet that Planet Fitness has decided to stop watching the GLP-1 wave from the sidelines.
The context matters. Planet Fitness closed 2025 with strong top-line momentum, ending the year with approximately 20.8 million members and nearly 2,900 clubs worldwide. The company added 1.1 million net new members and reported $1.3 billion in full-year revenue, up 12.1%, in 2025. System-wide same-club sales increased 6.7% and adjusted EBITDA jumped to $551.6 million from $487.7 million the prior year. Numbers like those give a CEO the confidence to bet on a new market segment. Keating signaled that GLP-1 users could be the next major untapped membership base, pointing to franchisee-commissioned survey findings that roughly half of people taking a GLP-1 medication consider joining a gym. “We see positive indicators for continued growth and demand for our offering as GLP-1s become more accessible,” Keating told investors during Planet’s Q4 earnings call.
The partnership with Ro is not a clinical play. Planet Fitness has partnered with GLP-1 provider Ro, operating as a referral-only model where members receive a referral and discount from the fitness chain. That distinction matters. Life Time, UFC GYM, Monarch, and Love.Life have moved into direct clinical integration — offering physician-supervised GLP-1 programs directly at club locations. Budget gyms are firmly in the referral lane. Planet Fitness’s Ro partnership is the first major High-Value, Low-Price (HVLP) play and operates as a referral-only model. Planet Fitness is not prescribing anything. It is sending its 20.8 million members toward a third-party telehealth platform and collecting credit for the conversion. That is the business. The identity question is what happens next.
Part of the positive outlook stems from Planet’s new Perks partnership with telehealth platform Ro, which offers GLP-1 prescriptions and counts tennis great Serena Williams as brand ambassador and client. Ro is a real, credentialed operation. But the referral is not. It is a discount code. A perk. A push notification. It is not a verifiable claim that you are a Planet Fitness member of a specific tier, in good standing, with an authenticated wellness profile. That gap sits at the center of everything that follows.
What Exists at .planetfitness Onchain — And What Doesn’t
The .planetfitness namespace exists as an onchain TLD, marketed toward fitness creators, wellness startups, and health-focused projects, with the option to register a domain or co-own the namespace with NameShares. It is not affiliated with or endorsed by the Planet Fitness® company. Planet Fitness the corporation — the one with 20.8 million members, $1.3 billion in revenue, and a freshly minted telehealth partnership — does not appear to hold or operate any onchain TLD under its own brand. There is no official .planetfitness registry controlled by the company. There is no health.planetfitness endpoint. There is no member credential that lives on a public ledger, no second-level domain map anchoring a wellness referral to a real membership, and no onchain handshake between the gym’s identity system and Ro’s prescription flow.
This is not a technical critique. It is an observation about a structural gap. Planet Fitness operates one of the largest consumer fitness databases in the world. Black Card penetration reached 66.5%, an all-time high. That means roughly two-thirds of the entire 20.8 million member base holds a premium tier membership. Those members have a documented relationship with the brand: payment history, check-in frequency, club location, membership tenure. None of that information is accessible to Ro. None of it is cryptographically verifiable. None of it can travel with the member without Planet Fitness acting as a centralized intermediary that decides what to share, with whom, and under what terms. The referral is a link. The identity behind it is invisible.
Compare this to what is becoming technically possible. Web3 TLDs are powered by blockchain name systems, including Handshake, Ethereum Name Service, or other decentralized naming protocols. These solutions guarantee that domain records are kept on-chain, making them transferable. It is now feasible to design a full namespace on the internet and build a custom TLD in the Web3 ecosystem thanks to blockchain technology and decentralized domain systems. A brand that operates a TLD at the root layer owns the SLD map beneath it. It can issue health.planetfitness, member.planetfitness, or blackcard.planetfitness as verifiable credentials rather than database rows locked behind a proprietary API. Planet Fitness has not done this. Whether the company knows the option exists is a different question.
The Use Case That Cannot Be Built Without the Identity Layer
Start with what Ro actually needs to function. When a Planet Fitness member clicks through a Perks referral to Ro’s Body Program, Ro receives a new prospective patient. GLP-1 telehealth programs use digital platforms to connect patients with certified clinicians who prescribe GLP-1 medications such as semaglutide or tirzepatide for weight loss or type 2 diabetes. Clinicians review each member’s medical history, eligibility, and lifestyle goals during secure virtual consultations. That intake process requires personal information. Name, date of birth, health history, address, insurance or payment method. The member types it in. Ro stores it. Planet Fitness sent the member there, but the member’s gym identity — their tenure, their tier, their check-in behavior — does not follow them. Ro cannot verify independently that the person filling out its intake form is actually an active Black Card member with 14 months of consistent check-in history. The referral discount is real. The verification behind it is a checkbox.
Now model the same flow with a health.planetfitness SLD functioning as a member-controlled wellness credential. The member holds the credential in a self-custody wallet. The credential is issued by Planet Fitness against the TLD it controls at the root layer. It contains verifiable claims: membership tier, join date, active status, perhaps aggregated visit frequency. When the member navigates to Ro, an agent operating on their behalf presents the credential. Verifiable credentials give AI agents a kind of digital ID. This lets servers confirm that “this agent is acting on behalf of a trusted user,” addressing what is called the Know Your Agent problem. Ro’s intake system does not need to call a Planet Fitness API or trust a session cookie. The credential proves origin. The member does not hand over raw PII to get a discount — the agent asserts the claim, the discount is unlocked, and the session proceeds.
The settlement layer for that interaction already exists. x402 is the internet’s payment standard. An open standard for internet-native payments that empowers agentic payments at scale. The x402 protocol activates the long-dormant HTTP 402 “Payment Required” status code and turns it into an actual payment mechanism. A client — a browser, an app, or an agent — requests a resource. The server responds with a price. The client authorizes a stablecoin payment. The resource is delivered. One HTTP round-trip. No accounts, no subscriptions, no API keys. Coinbase launched x402 in May 2025 with a simple premise: kill the API key, enable economic reasoning for LLMs, and close the earn/spend loop on the agentic economy. The x402 Foundation, co-founded by Coinbase and Cloudflare, now includes Google and Visa. Google has integrated x402 into its Agent Payments Protocol.
The practical shape of this for Planet Fitness is not speculative in structure — only in execution. An agent authenticated via a health.planetfitness SLD could present a membership credential, trigger an x402 micropayment that unlocks a Ro intake session at the partner discount rate, and log the completed handshake on-chain. ERC-8004 and x402 form a complete autonomous transaction loop. ERC-8004 answers “who you are” and “how trustworthy you are” through on-chain identity and reputation, while x402 handles “how agents pay each other” via HTTP-native micropayments. The member controls their own credential. The data never leaves the credential envelope unless the member authorizes it. Planet Fitness does not become a healthcare data custodian. Ro does not receive raw PII to validate a discount that a discount code already granted. The combination of ERC-8004 and x402 provides AI agents with a cryptographic passport for accountability and a universal payment protocol for machine-to-machine commerce.
None of this can be built on a referral link. A referral link has no identity layer. It has no provable origin. It cannot be presented by an agent. It cannot be composed with downstream credentials. It cannot be audited by the member after the fact. It is a marketing primitive dressed up as an identity claim. Planet Fitness called the Ro Perks program the most successful in company history based on download and conversion rates. Those metrics are real. What they measure is the top of the funnel — how many members clicked and how many signed up. They do not measure how many members were correctly identified, how much PII moved unnecessarily across to a third party, or whether any member in that flow retained any control over their own wellness identity after the handshake was complete. They cannot measure those things. The identity layer to support that measurement does not exist.
The competitive picture is already shifting. Crunch Fitness, with 550-plus locations, has partnered with Thrive to bring GLP-1 medication access and programming support to members across its network, expanding telehealth-fitness integration into the HVLP segment. In-Shape Family Fitness has partnered with KORB Health to offer white-label clinical integration with GLP-1s, marking one of the first regional chain GLP-1 integrations via white-label pharmaceutical supply. The fitness-to-telehealth referral model is becoming a category, not a differentiator. When the referral model commoditizes — and it will — the brands that have built verifiable identity infrastructure between their membership database and their clinical partners will have a structural advantage. Those that built a Perks page and a discount code will not.
The Quiet Problem at the Center of a Very Loud Announcement
Planet Fitness has 20.8 million members. It has the most successful Perks program in its history by its own account. It has a CEO who is clearly paying attention to the GLP-1 tailwind and a franchisee base sophisticated enough to commission survey data on it. The Centers for Medicare and Medicaid Services require GLP-1 Medicare and Medicaid patients to enroll in a lifestyle support program — opening the door for brands to become certified government-authorized lifestyle providers starting May 2026. The regulatory direction of travel puts fitness brands squarely in the clinical adjacency business, not just the referral business. That adjacency demands something a discount code cannot provide: a verified, member-controlled, privacy-respecting identity claim that travels between institutions without exposing the raw data that makes it true.
In January 2026, three foundational layers converged — x402 payments, onchain identity, and autonomous agents. The infrastructure for what comes next is already shipping. The brands building identity at the root layer of their namespace now will be the ones whose member credentials are readable, composable, and trustworthy when the agentic wellness stack matures. Planet Fitness routed its 20.8 million members toward a clinical partner this quarter. It did so without a single one of those members holding a verifiable, onchain record of who they are to the brand that just vouched for them.
That is not a headline. It is an architectural condition. And architectural conditions do not fix themselves on the next earnings call.
