Oura Arbitration Agreement Takes Effect: Class Action Waiver and 20-Case Batching Meet the Oura Ring Lawsuit

The Oura arbitration agreement is now live: Oura's revised Terms of Use, dated Oct. 2, 2026 and effective Nov. 4, 2026, require individual arbitration of every US claim against the smart-ring maker, waive class actions and jury trials, and add a mass-filing protocol that sends only 20 randomly chosen demands forward at a time once 25 or more similar demands arrive. The change matters because it takes effect while Oura's motion to compel arbitration is pending in Surber v. Oura Inc., the proposed nationwide class action over the ring's "95% Sleep Staging Accuracy" marketing, and on the same day a second federal suit, A.G. v. Oura Inc., was filed in San Francisco.

The rollout is a textbook example of a consumer brand rebuilding its dispute terms with mass arbitration in mind. It also sets up a recurring question in the Northern District of California: whether terms published after a putative class action is filed can reach the people that suit seeks to represent. This article sets out what Section XVI says, how its batching machinery works step by step, where the pending litigation stands, and what the Oura arbitration agreement means for drafters, claimants' counsel and defendants.

A note on sourcing: the analysis below draws on the text of Oura's terms page as indexed by search engines, the Surber complaint, docket summaries and contemporaneous reporting. Where trackers disagree on a date or detail, the disagreement is flagged rather than resolved by guesswork.

What changed on Nov. 4, 2026

Oura's terms page now opens its dispute section with a direct statement: Section XVI "contains an arbitration agreement and class action waiver that apply to all claims brought against Oura in the United States." The provision also includes a jury trial waiver. Settlement Insight and the terms-tracking service ConductAtlas both date the revision to Oct. 2, 2026, with an effective date of Nov. 4, 2026; one ConductAtlas provision record lists a "last updated" date of May 5, 2026, a discrepancy that likely reflects the tracker's own capture history rather than a separate Oura revision.

The headline features of the new Oura arbitration agreement are:

• Individual arbitration only. Disputes go to a single arbitrator administered by the American Arbitration Association (AAA), with no class, collective or representative proceedings.
• A Class Action Waiver. Users may not bring, join or lead a class or representative action against Oura, except where the law forbids that restriction.
• A Pre-Arbitration Notice requirement. At least 30 days before either side starts an arbitration, each must send the other an individualized written "Pre-Dispute Notice" and try in good faith to negotiate an informal resolution of that individual claim.
• A Small Claims Carve-Out. Either side may take a qualifying claim to local small claims court instead.
• A mass-filing protocol. Twenty-five or more similar demands from claimants who share counsel, or whose counsel coordinate, trigger a staged process run by a Limited Service Neutral.
• AAA fees. Each party pays the fees required under the applicable AAA fee schedule, subject to the deferral built into the mass-filing protocol.

ConductAtlas's provision records also describe a one-year contractual limitations period for non-EU users, a $100 cap on Oura's liability where liability cannot be excluded, carve-outs for certain injunctive relief, and exclusive jurisdiction in the state or federal courts in San Francisco for disputes that are not arbitrated. Those terms come from a single tracker and should be checked against the live text before anyone relies on them.

Does Oura have an arbitration agreement?

Yes. Since Nov. 4, 2026, Oura's Terms of Use have contained a binding arbitration agreement and class action waiver covering all claims brought against Oura in the United States, with a jury trial waiver and a small claims court exception.

The earlier version of the terms, which Oura still posts as "Previous Terms and Conditions," already referred disputes to arbitration before a single arbitrator and required claims to be filed within one year, according to search summaries of that document, but it did not contain a class action waiver. That distinction is less dramatic than it looks. Under Stolt-Nielsen S.A. v. AnimalFeeds International Corp. (2010) and Lamps Plus, Inc. v. Varela (2019), an arbitrator cannot order class arbitration unless the parties affirmatively agreed to it, so an arbitration clause that is silent about class procedures already pushes claimants toward individual proceedings. The new waiver closes the door in court as well, and the mass-filing protocol addresses what happens when thousands of individual demands arrive at once.

What is the Oura ring lawsuit about?

Surber v. Oura Inc., No. 3:26-cv-08686, was filed Aug. 20, 2026 in the US District Court for the Northern District of California by Clarkson Law Firm. The plaintiff, Madison Surber, bought an Oura Ring in May 2025. The defendants are Oura Inc., the US entity headquartered in San Francisco, and its Finnish parent, Oura Health Oy.

The complaint targets Oura's advertising that the ring delivers "95% Sleep Staging Accuracy compared to clinical sleep lab," a figure that, according to the complaint and coverage of it, replaced an earlier 79% claim. The plaintiff alleges that accurately classifying sleep stages requires electrodes on the scalp and sensors around the eyes and chin, which a finger-worn ring lacks, and cites peer-reviewed work putting the ring's four-stage accuracy far lower, including a study figure of 53.18%. Oura's position, as reported, is that the 95% figure describes the ring's ability to tell sleep from wakefulness rather than its accuracy in identifying each of four sleep stages; an industry analysis by MD+DI reports that Oura's own healthy-adult study showed 95% sleep sensitivity and 76% four-stage agreement.

The suit covers the Oura Ring 5, Ring 4 and Ring 4 Ceramic, proposes a nationwide class and a California subclass, and seeks injunctive relief and restitution under California consumer protection law. It is a false-advertising case, not a personal injury case: no physical harm is alleged.

A separate proposed class action, Lekhadia v. Oura Health, filed in December 2025 in the same district, alleges that Oura failed to clearly disclose its membership auto-renewal terms and lacked an easy cancellation path, in violation of California law. The newest suit, A.G. v. Oura Inc., No. 3:26-cv-13131, was filed Nov. 4, 2026, with summons issued Nov. 9; its claims have not been publicly reported.

Where the litigation stands: a timeline

Date	Event
Mar. 21, 2025	Ninth Circuit affirms denial of Oura's motion to compel arbitration in Attia v. Oura Ring, Inc., No. 24-2622 (advisor agreement without an arbitration clause)
Dec. 2025	Lekhadia v. Oura Health filed in N.D. Cal. over membership auto-renewal disclosures
Aug. 20, 2026	Surber v. Oura Inc., No. 3:26-cv-08686, filed in N.D. Cal. over the 95% sleep-staging claim
Sept. 3, 2026	Oura publicly files its Form S-1 for a Nasdaq listing under the ticker OURA
Sept. 10, 2026	Oura moves to compel arbitration in Surber (Dkt. 13), noticing a hearing for Oct. 29
Oct. 2, 2026	Revised Terms of Use published, with Section XVI arbitration and class waiver
Early Oct. 2026	Surber opposition filed (trackers list Oct. 8 or Oct. 9); Oura replies Oct. 15
Oct. 26, 2026	Docket trackers show the Oct. 29 hearing entry terminated
Nov. 4, 2026	New terms take effect; A.G. v. Oura Inc., No. 3:26-cv-13131, filed
Nov. 9, 2026	Summons issued in A.G. v. Oura
Nov. 10, 2026	No ruling on the Surber motion, no class certification, no settlement reported

Judge James Donato presides over Surber. The termination of the hearing entry is consistent with the court taking the motion on the papers, which Northern District judges frequently do under Civil Local Rule 7-1(b), but no order had been reported as of Nov. 10.

Inside Section XVI: the Oura arbitration agreement clause by clause

Feature	What Oura's terms provide	Comparison point
Scope	All claims brought against Oura in the United States	Prior terms had arbitration but no class waiver
Forum	AAA, single arbitrator	AAA Consumer Arbitration Rules and Mass Arbitration Supplementary Rules
Pre-dispute step	Individualized written notice, 30-day good-faith negotiation	Common in post-2022 consumer clauses; enforceability turns on tolling and burden
Small claims	Either party may elect small claims court	Standard carve-out, mirrors AAA consumer due process protocol
Mass-filing trigger	25+ similar demands, same or coordinated counsel	Matches the AAA's 25-case Mass Filing Threshold
First wave	Limited Service Neutral randomly selects 20 Initial Cases within 30 days of AAA designation	Random selection, not party-picked bellwethers
Everyone else	Remaining Cases held in abeyance; no filing, administrative or arbitrator fees until selected or resolved	Fee deferral limits up-front respondent exposure
After wave one	Mediation within 45 days after the last Initial Case is resolved	Mediation step before the next wave
Later waves	Another random 20 if mediation fails; number can change by written agreement	Staggered Processing in fixed increments
Exit ramp	Claimant may withdraw from the mass proceeding and file an individual AAA demand	Answers a common unconscionability attack
Jury	Jury trial waiver	Applies to any claim that stays in court

How does Oura's mass arbitration process work?

When 25 or more demands raising the same or substantially similar claims are filed by claimants represented by the same lawyer, or by lawyers acting in coordination, the filing is treated as a mass filing. Within 30 days after the AAA designates it as such, a Limited Service Neutral randomly selects 20 individual demands, called the "Initial Cases." Only those 20 are filed with the AAA and proceed to arbitration; all the others, the "Remaining Cases," are held in abeyance, and no filing, administrative or arbitrator fees are assessed on them unless and until they are selected or otherwise resolved.

Within 45 days after the last Initial Case has been decided or otherwise resolved, the parties must take part in a mediation before a mutually agreed mediator to try to resolve the Remaining Cases. If that mediation does not resolve everything, the Limited Service Neutral randomly picks another group of 20 cases, which proceed under the same procedure. The parties can change the batch size by written agreement. Throughout, an individual claimant keeps the right to withdraw from the mass proceeding and file an individual demand with the AAA.

This is a form of Batching combined with a Bellwether Provision (Arbitration), but with two design choices that distinguish it from more aggressive clauses. First, selection is random and administered by a neutral, so neither side can cherry-pick the strongest or weakest demands for the first wave. Second, fees on held demands are expressly deferred, so the respondent is not exposed to thousands of initiation fees at once, and claimants are not asked to pay to sit in a queue.

The arithmetic is what claimants' counsel will focus on. At 20 cases per round, with a mediation of up to 45 days after each round, a filing of 5,000 demands would take 250 rounds to clear if no global deal is reached. That is the pressure point that has drawn unconscionability challenges to similar clauses elsewhere. Whether a court would treat Oura's version as reasonable claims management or as a delay mechanism will depend on facts that do not yet exist, including how fast a 20-case round actually moves and whether limitations periods are tolled for held demands. Search summaries of Section XVI did not surface an express Tolling Provision; that is a detail practitioners should confirm in the live text.

Do Oura's new arbitration terms apply to the pending Surber lawsuit?

No court has decided that question, and nothing in the public record shows Oura asking a court to apply the Nov. 4 terms to Surber. Oura's Sept. 10 motion to compel necessarily rests on whatever agreement existed before the revision, because the new terms were not yet in effect when it was filed.

If Oura later invokes the new terms against Surber or the putative class, three lines of authority will frame the fight:

1. Communications with a putative class. Federal courts have authority under Rule 23(d) to police communications with absent class members once a case is filed. In O'Connor v. Uber Technologies (N.D. Cal. 2014), Judge Edward Chen required Uber to give corrective notice and an opt-out after it rolled out a new arbitration agreement during a pending class action. In In re Currency Conversion Fee Antitrust Litigation (S.D.N.Y. 2005), the court refused to enforce arbitration clauses that card issuers added after the suit was filed against putative class members who were not told about the case. Those decisions do not void post-suit clauses automatically, but they give judges tools to limit them.
2. Accrued and known claims. California courts have held that a party's unilateral right to modify an arbitration agreement is constrained by the implied covenant of good faith and fair dealing, and that modifications generally cannot be applied to claims that had already accrued or were known when the change was made. Peleg v. Neiman Marcus Group, Inc. (Cal. Ct. App. 2012), is the leading example. A buyer who purchased a ring in 2025 and is already a named plaintiff presents the clearest accrued-claim scenario.
3. Assent. For anyone who bought before Nov. 4, enforceability will depend on how Oura gave notice of the change and whether continued use of the app counts as acceptance under the browsewrap and sign-in-wrap line of cases, including Berman v. Freedom Financial Network (9th Cir. 2022). Notice that appears only on a website, without a conspicuous prompt in the app, tends to fare poorly in the Ninth Circuit.

Oura's own arbitration record in the circuit is mixed. In Attia v. Oura Ring, Inc., the Ninth Circuit in March 2025 affirmed the denial of Oura's motion to compel arbitration of claims by former advisor Peter Attia, because Oura conceded that a second agreement governing his advisory role contained no arbitration provision. A separate stock-option suit by a former chief executive was likewise kept in court in 2026, according to MLex. Those were commercial disputes with individually negotiated documents, not consumer Contracts of Adhesion, but they show that Oura's arbitration motions are not self-executing.

Can you opt out of Oura's arbitration agreement?

Published summaries of Section XVI, including ConductAtlas's review of the provision, did not locate an opt-out window in the Oura arbitration agreement. That is notable because many consumer clauses offer a 30-day Opt-Out Clause precisely to bolster enforceability against procedural Unconscionability challenges. The 30-day period that does appear in Oura's terms is the Pre-Dispute Notice and negotiation period, not an opt-out. A separate company with a similar name, OuraCare (operated by Hyperscale Brands LLC), does offer a 30-day arbitration opt-out in its own terms, which has caused some confusion online; it is unrelated to Oura's ring and membership terms.

How the Oura protocol compares with other mass arbitration clauses

The 25-demand trigger tracks the threshold in the AAA's Mass Arbitration Supplementary Rules, which apply when 25 or more similar consumer or employment demands are filed against the same or related parties with coordinated counsel. Aligning the contractual Mass Filing Threshold with the provider's own threshold avoids an argument that the clause and the rules conflict, a recurring problem in earlier drafting.

The clause also reads as if it were written with Heckman v. Live Nation Entertainment, Inc. (9th Cir. 2024) in view. There, the Ninth Circuit refused to enforce Ticketmaster's terms, which sent disputes to New Era ADR under mass-arbitration procedures the court found unconscionable, in part because bellwether outcomes could bind non-participating claimants and because the process limited discovery and appeal rights in ways that favored the repeat-player respondent. Oura's version avoids several of the features criticized in Heckman: it uses the AAA rather than a newer provider, selects cases randomly through a neutral, defers fees for held claims, and preserves an individual exit. It does not, on the available text, make Initial Case outcomes binding on Remaining Cases.

What it shares with Heckman-era clauses is fixed-increment processing. Courts have been more receptive to batching when batches are large enough to move a docket and less receptive when the design leaves most claimants waiting indefinitely. The MassArbitration.co guide to how the AAA and JAMS rulebooks now treat mass filings explains why many respondents have moved from bespoke batching toward provider-administered procedures.

Two further points matter for California consumers. First, the McGill Rule bars waivers of the right to seek public injunctive relief in any forum, and ConductAtlas reports that Oura's terms carve California public injunctive relief claims out of arbitration and stay them pending resolution of arbitrable claims, a structure courts in the state have generally accepted. Second, California Code of Civil Procedure §§ 1281.97–1281.98 penalize a business that fails to pay arbitration fees within 30 days of the due date. Oura's fee deferral for held demands is drafted so that no fee comes due on a held case, which should keep the protocol clear of the statute's forfeiture remedy as long as Oura pays on time for the cases that are filed.

Why Oura is tightening its terms now: the IPO backdrop

Oura publicly filed a Form S-1 registration statement on Sept. 3, 2026, for a Nasdaq listing under the ticker OURA. The filing reported $1.21 billion in revenue for the nine months ended June 30, 2026, up 74% from $698 million a year earlier, and 5 million paid members. Its risk factors list consumer protection and false advertising litigation among current and future legal proceedings, and they flag litigation over claims the company makes about data accuracy.

For a subscription business with millions of US members, the economics of a sleep-accuracy claim are classic Negative-Value Claim territory: individual damages measured against the price of a ring or a membership are small, which is why plaintiffs file class actions and why defendants prefer individual arbitration. The countervailing risk, which the mass-filing protocol is built to manage, is that claimant firms convert a blocked class action into thousands of individual demands, each carrying provider fees payable by the respondent. The Oura arbitration agreement aims to make that strategy slower and cheaper to defend without giving claimants an easy unconscionability argument.

What it means for drafters, claimants' counsel and defendants

For clause drafters. Oura's Section XVI is a current, publicly available template that combines a provider-matched 25-demand threshold, random neutral selection, fee deferral, a post-round mediation and an individual withdrawal right. Drafters copying the structure should pay attention to the features that could not be confirmed from public summaries: an express tolling provision for held demands, a Delegation Clause sending enforceability disputes to the arbitrator, and an opt-out window. Each is a common pressure point in enforceability litigation.

For claimants' counsel. The protocol makes a mass campaign slower, but it does not forbid one. Counsel weighing demands should consider the Pre-Dispute Notice requirement (individualized notices for each claimant), the absence of fees on held cases (which removes the classic fee-pressure lever), and the withdrawal right, which allows an individual claimant to leave the queue and file alone. For purchasers before Nov. 4, the threshold question is whether the new terms bind them at all; Surber's counsel can be expected to argue that they do not reach a pending putative class.

For defense counsel. Rolling out new terms during pending class litigation invites a Rule 23(d) motion for corrective notice. Companies in Oura's position commonly reduce that risk by carving pending cases and represented parties out of a revision or by including explicit notice of the pending suit. Whether Oura did so is not apparent from the public summaries, and how it handles the Surber class will be closely watched.

For consumers. No settlement, fund, claim form or payout date exists in any Oura case as of Nov. 10, 2026. Settlement-tracking sites promising Oura payouts are describing pending lawsuits, not money available to claim.

Frequently asked questions

When did Oura's new terms of use take effect?

Oura's revised Terms of Use, dated Oct. 2, 2026, took effect Nov. 4, 2026. They added the Section XVI arbitration agreement, class action waiver and mass-filing protocol for US claims.

Can I still join the Oura ring class action?

Surber v. Oura Inc. is a proposed class action that has not been certified, so there is nothing to join yet; members of a certified class are typically included automatically and notified later. Whether purchasers are bound by Oura's arbitration agreement, and therefore excluded from any class, is the issue raised by Oura's pending motion to compel.

Is there an Oura ring settlement or payout?

No. As of Nov. 10, 2026, neither Surber v. Oura nor A.G. v. Oura has produced a settlement, a settlement fund, a claims administrator or a payout date.

How many cases go first in an Oura mass arbitration?

Twenty. Once 25 or more similar demands from coordinated counsel are filed, a Limited Service Neutral randomly selects 20 Initial Cases; the rest wait, fee-free, until mediation or a later random batch of 20.

Who is the judge in the Oura sleep-tracking lawsuit?

US District Judge James Donato of the Northern District of California presides over Surber v. Oura Inc., No. 3:26-cv-08686, and has Oura's Sept. 10, 2026 motion to compel arbitration before him.

Does the Oura arbitration agreement cover claims outside the United States?

No. Section XVI states that it applies to claims brought against Oura in the United States, and trackers report that some related terms, such as the one-year limitations period, expressly exclude EU users.
