Class Action Funding: Financing Lead Plaintiffs and Class Counsel

How funders support class actions, the opt-in and opt-out distinction, and the certification risk that drives value.

Class action funding provides capital to class counsel and lead plaintiffs prosecuting representative litigation on behalf of large groups. Class actions allow a small number of named plaintiffs to litigate claims shared by many similarly situated individuals, aggregating modest individual harms into a single proceeding of substantial value. Because class litigation is expensive and protracted, with significant cost concentrated before any recovery, it is a natural candidate for third-party funding.

A foundational distinction is between opt-out and opt-in mechanisms. Most damages class actions in the United States proceed under Federal Rule of Civil Procedure 23 on an opt-out basis: all class members are bound unless they affirmatively exclude themselves. Certain federal statutes, notably the Fair Labor Standards Act, instead require members to opt in by filing consent. The mechanism affects the size of the class, the predictability of participation, and the ultimate value, all of which funders weigh in underwriting.

Class certification is the decisive moment. Under Rule 23, plaintiffs must satisfy numerosity, commonality, typicality, and adequacy, and most damages classes must additionally show that common questions predominate and that a class action is superior to other methods. The certification decision typically determines settlement leverage: a certified class compels serious settlement discussions, while a denial can reduce the matter to individual claims of little aggregate value. Funders model certification probability as the central variable in expected recovery.

Funding structures support class counsel through the years of work that precede recovery, covering expert costs, notice and administration expenses, and the carrying cost of the firm's time. The funder's return is paid from the common fund or fee award upon resolution, structured to comply with professional responsibility rules governing fee arrangements. The funder does not control litigation or settlement decisions, which remain with class counsel subject to court approval of any class settlement.

Criterica Capital underwrites class action funding using outcome models trained on 106M+ court records, calibrating certification and settlement probability against the disposition history of comparable class dockets. This grounds our pricing in observed outcomes rather than in the reputation of class counsel. Firms prosecuting class litigation can contact our institutional team to discuss funding arrangements.
