Affirm vs. Klarna: Which BNPL Technology Stock Looks Better in 2026?

Market snapshot and business models

As the buy now, pay later (BNPL) market matures, investors face a choice between two prominent digital-finance players: Affirm (NASDAQ: AFRM) and Klarna Group (NYSE: KLAR). Both companies aim to supplant traditional credit cards at checkout, but they follow different strategies and operate on different scales.

Affirm built its reputation in the U.S. on transparent lending for larger-ticket purchases, offering interest-free and simple-interest loan options and longer-term payment plans that can stretch from one month to five years. The company has secured high-profile commercial partnerships with major retailers including Amazon and Shopify that help drive transaction volume. That concentration of merchant partners boosts scale but also introduces partner-concentration risk if any major partner shifts strategy. Affirm reported roughly 377,000 active merchants using its underwriting tools.

Klarna has transformed from a payments provider into a global digital bank. It serves about 118 million active consumers and works with nearly 966,000 merchants across 26 countries, partnering with brands such as Uber, Nike, and Airbnb. Klarna focuses on high-frequency, smaller e-commerce purchases and a broader set of banking and shopping tools, targeting frequent engagement as the primary financial app for users. Its international footprint diversifies revenue across geographies but exposes it to more complex regulatory and compliance environments.

Financials, risk profile and valuation

For fiscal year 2025 Affirm recorded revenue of approximately $3.2 billion, up about 38.8% year over year, and reported net income close to $52.2 million, implying a net margin near 1.6%. Affirms free cash flow for the fiscal year was about $601.7 million, though stock-based compensation accounted for roughly 40.5% of operating cash flow a reminder that add-backs can inflate reported cash generation. On the balance sheet, Affirms June 2025 current ratio was reported around 54.2x and its debt-to-equity ratio about 2.6x.

Klarna generated roughly $3.5 billion in revenue for FY 2025, up about 31.6% year over year, but it recorded a net loss near $294.0 million and a net margin of roughly -8.4%. Klarna reported negative free cash flow of approximately -$1.0 billion for the period, reflecting investment-led spending tied to aggressive international expansion. At the end of December 2025, Klarnas debt-to-equity ratio was about 0.5x and its current ratio approximately 1.0x, indicating a capital structure and liquidity profile materially different from Affirms.

Risk profiles diverge as well. Affirm depends on a relatively small set of originating bank partners such as Celtic Bank; the loss of those relationships could hamper its ability to fund loans. It also competes with legacy credit-card issuers and fintech rivals including PayPal (NASDAQ: PYPL). Klarnas risks are concentrated around operating as a regulated global bankchanges in regulation or compliance costs can be materialand competition from tech giants that embed payments into ecosystems, including Apple (NASDAQ: AAPL) and Alphabet (NASDAQ: GOOG / GOOGL).

On valuation metrics, Affirm looked more attractive on forward earnings estimates, with a forward P/E around 58.8x compared with Klarnas 89.2x. That said, Klarna trades at a lower price-to-sales multiple (P/S ~2.0x) than Affirm (P/S ~7.6x). For context, the sector benchmark using the SPDR XLK ETF sits at a forward P/E of about 40.4x. These differences reflect the companies divergent profitability profiles and investor expectations for future growth.

Which stock might an investor prefer in 2026?

Both Affirm and Klarna operate in the BNPL space and have built extensive merchant networks and recognizable partnerships. But their business mixes are different: Affirm tilts toward fewer, higher-value transactions tied to major retail partners and has reached GAAP profitability, while Klarna relies on higher-frequency, smaller purchases across a global user base but remains unprofitable and cash-negative as it invests in growth.

The authors view favors Affirm as the better buy in 2026. The rationale centers on Affirms partnerships with large, established retailers that are less sensitive to cyclical consumer weakness and the companys recent progress to GAAP profitability. Klarna is not dismissedits scale, product breadth, and international diversification are meaningful advantagesbut weaker consumer spending patterns and delinquency risk, combined with continued negative free cash flow, make Klarna a more speculative pick in the near term.

Before making any trade, investors should weigh these operational differences, check the latest financials and guidance, and consider how much exposure they want to merchant concentration, international regulatory risk, and continued investment-driven cash burn. The Motley Fools Stock Advisor team did not include Affirm among its 10 best stocks at the time of publication, which is an additional data point investors may factor into their own decision process.

Ultimately, both names remain central plays on the evolution of payments. Affirm may appeal to investors seeking a route to profitability with concentrated retail partnerships, while Klarna may suit those willing to accept higher near-term losses for broader international scale and potential longer-term returns.
