Funders and class actions: the economics
Litigation funding companies occupy a structural position in class actions that is widely misunderstood, and getting the economics wrong at the outset produces consequences that neither lawyers nor claimants can easily reverse.
Funders and class actions: the economics
The economics of litigation funding in class actions are more intricate than most participants appreciate, and that gap in understanding shapes every decision that follows. Litigation funding companies are not passive cheque-writers who sit at the back of the room until a settlement lands. They are active capital allocators operating under return constraints, portfolio logic, and regulatory pressures that interact with the structure of collective proceedings in ways that legal teams often fail to model correctly. When those interactions are misunderstood, funding terms are negotiated poorly, case strategy drifts away from what the capital structure can actually support, and the interests of the group members the proceedings are supposed to serve become secondary to the mechanics of keeping the funding arrangement intact. This essay examines the underlying economics, the commercial consequences of getting them wrong, and where the market is likely to move as the regulatory environment tightens.
What the market usually gets wrong
The dominant misconception is that litigation funding is simply a form of contingency finance: the funder pays the bills, the case resolves, and the funder takes a share of the proceeds. That framing is not wrong in outline, but it obscures the structural features that actually drive funder behaviour throughout the life of a case.
The first structural feature is duration risk. Class actions, particularly in competition law, financial services, and consumer redress contexts, routinely run for several years from the point of funding commitment to the point of resolution. A funder committing capital to a case that takes five or more years to resolve is not simply lending money at a fixed rate. It is making an illiquid investment with a highly uncertain exit timeline, and it is doing so in a portfolio context where duration mismatches across cases can create real capital pressure. The longer a case runs, the more expensive it becomes for the funder in opportunity cost terms, and that pressure does not remain invisible. It surfaces in funding agreement terms, in the funder's appetite for settlement at various stages, and in the funder's willingness to support adverse costs exposure as the case develops.
The second structural feature is the relationship between the multiple of invested capital return and the percentage of proceeds return. Most funding agreements specify both, and the applicable mechanism is whichever produces the higher return at the point of resolution. In a case where costs are modest relative to the damages sought, the multiple return will often be the binding constraint early in the case and the percentage return will become binding as the case matures and costs accumulate. Legal teams that do not model this dynamic carefully can find themselves in a position where the funder's economic interest diverges from the group's interest at precisely the moment when settlement decisions need to be made.
The third structural feature is adverse costs exposure. In jurisdictions where the costs-shifting principle applies, the funder's liability for adverse costs if the case fails is a real and material risk. Litigation funding companies manage this risk through after-the-event insurance, through the structure of the funding agreement itself, and through portfolio diversification. But the cost of that risk management is embedded in the funding terms, and it is not always visible to the legal team or the group members as a discrete line item. Understanding where adverse costs exposure sits in the capital structure matters because it affects how the funder prices the risk of continuing to fund as the case develops and new information about the defendant's position emerges.
What actually changes when you look at the operating layer
When you move from the headline economics to the operating layer, several features of the funder-case relationship become clearer and more consequential.
Funding agreements in class actions are not standardised instruments. They are negotiated documents that reflect the specific risk profile of the case, the funder's portfolio position at the time of commitment, and the leverage that the legal team and the representative claimant bring to the negotiation. The terms that matter most are not always the headline return multiple or the percentage share. They are the provisions that govern what happens when the case encounters difficulty: the funder's right to withdraw, the conditions under which the funder can require the legal team to pursue or decline a settlement, and the mechanism for resolving disputes between the funder and the legal team about case strategy.
These provisions are where the operating economics become visible. A funder that has committed capital to a case and then encounters an adverse interlocutory ruling faces a genuine decision about whether to continue funding. That decision is not purely legal. It is a capital allocation decision made in the context of the funder's overall portfolio, its obligations to its own investors, and its assessment of how the case is likely to develop. If the funding agreement gives the funder broad withdrawal rights, the legal team and the group members are exposed to a risk that is not captured in the headline economics at all.
The operating layer also reveals the importance of the costs budget. In collective proceedings, costs budgets are subject to judicial scrutiny, and the relationship between the approved costs budget and the funding commitment is a live issue throughout the case. Litigation funding companies are sophisticated enough to model costs trajectories, but those models are built on assumptions about how the case will develop that may not survive contact with the defendant's litigation strategy. When costs exceed the budget, the funder faces a choice between committing additional capital and withdrawing, and the terms on which additional capital is committed will reflect the changed risk profile of the case at that point rather than the original terms.
For a broader view of how these dynamics interact with the structure of collective proceedings in England and Wales, the class actions and collective redress pillar sets out the relevant procedural context in more detail.
Commercial consequences
The commercial consequences of misunderstanding the economics of litigation funding in class actions fall on three groups: the legal teams running the cases, the group members whose interests the proceedings are meant to serve, and the litigation funding companies themselves.
For legal teams, the primary consequence is strategic misalignment. If the legal team does not understand the funder's economic position at each stage of the case, it cannot anticipate the funder's likely behaviour when the case reaches a decision point. That matters because the funder's decision to continue or withdraw, to support or resist a settlement, and to commit or withhold additional capital will shape the case's trajectory in ways that the legal team cannot control if it has not built the funder's economics into its strategic model from the outset.
For group members, the primary consequence is a risk that the proceedings are resolved in a way that serves the capital structure rather than their interests. This is not a theoretical risk. It is a structural feature of any arrangement where a third party with a financial interest in the outcome has contractual rights that can influence the conduct of the proceedings. The regulatory response to this risk, in the form of judicial oversight of funding arrangements and the development of standards for funder conduct, reflects a recognition that the interests of group members need to be protected by mechanisms that sit outside the funding agreement itself.
For litigation funding companies, the commercial consequence of the market's misunderstanding of their economics is reputational and regulatory. When funders are characterised as passive financiers rather than active participants in the economics of the proceedings, the scrutiny applied to their conduct and their terms is lower than it should be. That lower scrutiny creates an environment in which poor practice can persist, and when poor practice produces visible harm to group members, the regulatory response tends to be broad rather than targeted. The result is a compliance burden that falls on all funders, including those whose practice is sound.

Where the market is likely to move next
The direction of travel in the regulation of litigation funding companies in the context of class actions is towards greater transparency and more explicit judicial oversight of funding terms. The debate about whether litigation funding agreements should be subject to disclosure, whether funders should be treated as parties to the proceedings for costs purposes, and whether the returns available to funders should be subject to a reasonableness test is active in multiple jurisdictions simultaneously.
In England and Wales, the Supreme Court's decision in PACCAR and the legislative response to it have already demonstrated that the legal framework governing funding agreements can shift quickly and with significant consequences for existing arrangements. The market's response to that shift, which involved rapid renegotiation of funding agreements and the development of new structures designed to sit outside the definition of damages-based agreements, illustrates both the adaptability of litigation funding companies and the fragility of arrangements that depend on a particular regulatory characterisation remaining stable.
The commercial implication for legal teams and for group members is that funding arrangements need to be structured with regulatory change in mind. A funding agreement that is optimal under the current regulatory framework but that would be materially disadvantageous to the group if the framework shifted is not a well-structured agreement. Building in provisions that address the possibility of regulatory change, and ensuring that the legal team understands the funder's likely response to such change, is part of the operating discipline that the economics of the market now require.
The broader trajectory is towards a market in which the economics of litigation funding in class actions are more visible, more contested, and more subject to external constraint than they have been. That is not necessarily a bad outcome. Greater transparency about funding terms and funder conduct is likely to produce better outcomes for group members, and a more clearly regulated market is likely to be a more sustainable one for funders whose practice is genuinely aligned with the interests of the groups they fund.
What this means in practice
The practical implication of understanding the economics of litigation funding in class actions is straightforward to state and demanding to execute. Legal teams need to model the funder's economic position as carefully as they model the merits of the underlying claim. That means understanding the return structure, the duration risk, the adverse costs exposure, and the provisions in the funding agreement that govern the funder's behaviour when the case encounters difficulty.
Group members and their representatives need to ensure that the oversight mechanisms available to them, whether through the court's supervision of the proceedings or through the terms of the funding agreement itself, are adequate to protect their interests if the funder's economic position and their interests diverge. And litigation funding companies that want to operate sustainably in this market need to be willing to accept the transparency and oversight that the market's maturation requires.
The economics of this market are not simple, and they are not static. But they are knowable, and the discipline of understanding them is the foundation on which sound decisions in collective proceedings are built.

The UK Supreme Court's decision in PACCAR required rapid renegotiation of litigation funding agreements and prompted the development of new funding structures designed to sit outside the statutory definition of damages-based agreements.
Legal teams and funders cannot treat funding agreements as stable instruments; regulatory reclassification can alter the enforceability and economics of existing arrangements at short notice, making regulatory resilience a core structuring requirement.
Litigation funding agreements in class actions typically specify both a multiple of invested capital return and a percentage of proceeds return, with the applicable mechanism being whichever produces the higher return at the point of resolution.
The binding economic constraint on a funder's behaviour shifts as a case matures and costs accumulate, meaning the funder's incentives at settlement are not fixed at the point of commitment and must be modelled dynamically by legal teams throughout the life of the case.
In collective proceedings subject to costs-shifting, litigation funding companies manage adverse costs exposure through after-the-event insurance and portfolio diversification, with the cost of that risk management embedded in funding terms rather than disclosed as a discrete line item.
Group members and their legal representatives cannot assess the true cost of a funding arrangement from the headline return terms alone; the embedded cost of adverse costs risk management must be identified and evaluated as part of any proper assessment of whether the funding terms are in the group's interests.
