Portfolio finance bundles multiple litigation or arbitration matters, often belonging to a single law firm or corporate legal department, into one funding facility, cross-collateralized so that the funder's return is based on the performance of the pool as a whole rather than any single case. This structural diversification is attractive to funders because losses on individual matters are offset by wins elsewhere in the portfolio, and it is attractive to claimants and firms because it typically comes at a meaningfully lower cost of capital than single-case financing.
Illustrative market terms bear this out: a typical single-case arrangement might carry roughly a 2.5x return multiple plus a 25% success fee, while an equivalent portfolio arrangement often runs closer to a 2.0x multiple with a 20% success fee, a direct pricing benefit of diversification passed back to the claimant or firm.
Portfolio structures have become the primary vehicle through which law firms access litigation finance at scale, letting a firm pursue new contingency-fee business, fund growth, or smooth cash flow without pledging any single case's outcome.
