The $4 Billion Bet: OWS Deepens Partnership With Affirm's BNPL Engine

NEW YORK, NY – May 20, 2026 – In a resounding endorsement of Affirm’s business model, alternative investment manager One William Street Capital Management (OWS) has dramatically expanded its capital partnership with the buy now, pay later (BNPL) giant. The deal, which brings OWS’s total cumulative investment in Affirm-originated assets to approximately $4 billion, provides the fintech with a substantial, long-term funding runway and signals strong institutional confidence in its technology-driven underwriting.

Under the newly expanded agreement, OWS has closed a dedicated fund to purchase approximately $1.5 billion of loans from Affirm through 2027. This is complemented by the extension of an existing purchasing facility, which will acquire an additional estimated $500 million in loans per year over the same period. The move deepens a relationship that began in 2021 and has steadily grown across multiple funding channels, including forward flow agreements and participation in Affirm’s asset-backed securitization (ABS) platform.

A Partnership Built on Performance

The decision by OWS to commit billions in long-term capital is not a speculative bet but a calculated investment rooted in years of collaboration and performance analysis. OWS, a firm managing over $8 billion in assets with deep expertise in structured credit, has had a front-row seat to Affirm's loan origination and performance since 2021. This latest expansion reflects a strong conviction in the BNPL provider's ability to manage credit risk effectively.

“Our expanded relationship with Affirm demonstrates our team’s ability to provide creative solutions to asset owners and originators, and to cultivate win-win partnerships that scale over time,” said Frank Prezioso, Deputy CIO at OWS. “By leveraging our deep expertise across the public and private asset-based and structured credit landscape, we identified Affirm’s approach to managing credit as a key competitive differentiator given their best-in-class underwriting and technology advantages.”

This confidence is backed by Affirm’s recent financial results. The company has demonstrated robust growth, reporting a 29% year-over-year increase in Gross Merchandise Volume (GMV) to $8.8 billion for the quarter ending December 31, 2023. More importantly for capital partners, it has shown disciplined credit management, with its provision for credit losses as a percentage of revenue decreasing during the same period, indicating strong portfolio health. This track record of balancing rapid growth with responsible lending is precisely what sophisticated credit investors like OWS look for.

The New Architects of Fintech Funding

This partnership is a powerful illustration of a defining trend in modern finance: the ascendance of specialized alternative investment managers as the primary capital engine for fintech innovation. Firms like OWS are stepping into a role that traditional banks have been slower to fill, providing flexible, bespoke capital solutions that are crucial for the growth of non-traditional lenders. OWS's Private Asset-Based Finance strategy is designed specifically to provide capital to specialty finance companies and fintechs through structures like forward flow agreements, portfolio acquisitions, and other tailored financing.

Unlike traditional bank loans, these structured credit solutions offer fintechs a more symbiotic relationship. Capital providers become deeply integrated partners, gaining direct exposure to asset performance while originators secure the stable, predictable funding needed to scale. This model allows a firm like Affirm to originate billions of dollars in consumer loans without having to hold them all on its own balance sheet, enabling capital efficiency and rapid expansion.

The OWS-Affirm deal showcases the sophistication of this ecosystem. By utilizing a mix of forward flow agreements and a dedicated fund, OWS provides Affirm with committed, multi-year capacity, insulating it from the short-term volatility of public capital markets. This long-term view is essential for a company building a large-scale consumer lending platform.

Affirm's Blueprint for Capital and Scale

For Affirm, the expanded OWS partnership is a cornerstone of a meticulously crafted, diversified funding strategy. Rather than relying on a single source of capital, the company has built a multi-channel architecture that includes whole loan sales to partners like OWS, a robust securitization program that bundles loans for sale to a wide range of investors, and its own balance sheet. This diversification is a key strategic advantage, enhancing financial resilience and ensuring the company can continue to support its merchant partners and consumers through various economic cycles.

“OWS has been a great partner to Affirm, bringing deep expertise in credit and asset-based finance, and a collaborative approach to structuring innovative programs,” said Monica Mehra, Senior Director of Capital Markets at Affirm. “We greatly appreciate their support as we continue to build long-term relationships with our capital partners and deliver positive credit outcomes through our superior underwriting technology.”

This approach serves as a case study for other fintechs on how to achieve scale sustainably. By proving the quality of its loan assets and the strength of its underwriting, Affirm has attracted long-term, institutional capital, creating a virtuous cycle: strong performance attracts more capital, which in turn fuels further growth and platform expansion. This strategic cultivation of capital relationships is as critical to Affirm’s success as its consumer-facing technology.

Navigating a Shifting BNPL Landscape

The substantial, multi-year commitment from OWS arrives at a pivotal moment for the BNPL industry. The sector faces headwinds from a shifting macroeconomic environment, including higher interest rates that can compress margins, and the looming prospect of increased regulatory scrutiny from bodies like the U.S. Consumer Financial Protection Bureau (CFPB). In this environment, securing a stable, long-term funding base is a significant competitive advantage.

This deal helps differentiate Affirm from its key competitors. While Klarna operates with a banking license in Europe, giving it access to deposits, and Afterpay is now integrated into the larger balance sheet of its parent company, Block Inc., Affirm operates as a standalone public company. Its success is therefore heavily dependent on its ability to convince the capital markets of its value and viability. This $4 billion commitment from a sophisticated credit investor is a powerful market signal that Affirm's model is built to last.

By locking in this significant funding capacity through 2027, Affirm gains predictability and strength. It can confidently pursue growth with major merchant partners, invest in its technology, and navigate potential market turbulence from a position of financial stability. This strategic alignment provides Affirm not just with capital, but with a powerful validation of its model as it competes to define the future of consumer finance.
