Klarna filed for a U.S. IPO in March, and the public listing has moved through the spring as one of the more closely watched fintech debuts of the year. The financial press has covered the valuation reset, the path from the 2021 peak to a more sober 2025 mark, and the broader read-through to the BNPL category. Less covered, but more relevant to this audience: what the IPO actually changes for the retailers that have Klarna sitting at their checkout.

We spent May talking through this with payments leads at a mix of mid-sized specialty retailers and a couple of larger ecommerce operators. The IPO itself is not the event for them. The disclosures that come with it are.

What retailers will actually learn

Public BNPL filings are unusually informative for the partners on the other side of the contract. Three categories of disclosure matter:

  • Merchant take rates by segment and geography. Retailers know what they pay individually. They generally do not know what categories pay on average, or how their rates compare to peers of similar size. Public filings put a band around that for the first time at scale.
  • Consumer default and delinquency trends. The headline number is interesting; the breakdown by cohort, product (Pay in 4 versus longer-term financing), and category is more so. Retailers offering BNPL on higher-AOV categories — furniture, electronics, fitness equipment — care about this in a different way than those offering it on apparel.
  • Unit economics by product. Pay in 4 and longer-term installment products have very different economics. Public disclosure will, for the first time, force a clean line between them. That matters for retailers thinking about which BNPL flavor to feature at checkout and which to bury.

A payments director at a national specialty retailer told us the rate disclosure is the piece most internal teams are watching. "We've been paying what we pay because that's what we negotiated. Once there's a published distribution, we have a real number to negotiate against."

The leverage shift

The other thing public listing changes is the leverage dynamic between BNPL providers and their large merchants. A private BNPL provider can negotiate quietly. A public one is operating in front of investors who care about take rate trajectory, default rates, and merchant concentration.

This cuts both ways. On one hand, large merchants gain visibility into the provider's cost structure and pricing flexibility, which is useful at the negotiating table. On the other hand, public BNPL providers will face pressure from investors to defend take rate, which could make rate concessions harder to extract — especially for the largest retailers, who would otherwise be exactly the accounts where concessions matter most.

A finance lead at a mid-sized ecommerce retailer framed it this way: "If their stock is trading on take rate stability, they can't quietly cut our rate without it showing up somewhere. That's a different negotiation than we've been having for the last three years."

What 2025 budgets are doing with this

The retailers we spoke to are doing two things ahead of the IPO. The first is delaying any BNPL contract renegotiation that doesn't have to happen in Q2, on the theory that post-IPO disclosure will give them better data to negotiate against. The second is running internal reviews of BNPL economics on a category-by-category basis — looking at lift, return rates on BNPL-funded purchases, and the net contribution after fees — partly because some of those reviews have not been refreshed since 2022 and the underlying economics have moved.

A few themes from those reviews worth flagging:

  • Return rates on BNPL-funded apparel purchases are running meaningfully higher than non-BNPL returns at several retailers we spoke to. The gap was directionally known; the magnitude is large enough that some operators are reconsidering whether to feature BNPL prominently in apparel checkout.
  • Higher-AOV categories where BNPL drives clear basket lift — large electronics, fitness, furniture, certain beauty and luxury — continue to pencil cleanly, and operators in those categories are mostly looking for rate concessions rather than reconsidering the channel.
  • The competitive landscape matters. With Affirm public for several years now, PayPal Pay Later competing on its own terms, and Apple having exited Pay Later in 2024, retailers have more leverage to play providers against each other than the 2021 narrative suggested.

What to watch after the listing

Three things will be worth tracking in the months after Klarna prices: how the disclosed take rate distribution compares to what's been rumored in the industry, what consumer default and delinquency trends look like on a clean basis (especially for the longer-term installment product), and whether the IPO triggers any move from competitors — Affirm in particular — to refresh their own disclosures or merchant pricing.

The IPO is Klarna's event. The data it produces will reshape the negotiating table for everyone else at checkout.
