This story examines the growing divide in the fintech industry, where a handful of dominant players like Stripe and Ramp have achieved astronomical private market valuations, while many other fintech firms struggle to raise funding or languish after going public. The article explores how factors like the AI investment narrative and the influx of private capital are fueling this unsustainable bubble in the fintech sector.

Why it matters

The widening gap between the 'haves' and 'have-nots' in fintech raises concerns about the long-term sustainability of the industry. Highly inflated private valuations could lead to a reckoning when the AI bubble eventually deflates, and the public markets may offer fewer opportunities for investors to capitalize on tech wealth creation as more companies stay private.

The details

The article cites examples of fintech giants like Stripe and Ramp, which have achieved sky-high private market valuations despite questions about whether they could maintain those levels if they went public. Meanwhile, other fintech firms like Brex and Chime have seen their valuations plummet after going public. The narrative around AI has been a key driver of the fintech bubble, as investors chase the perceived winners of the AI revolution, while overlooking companies not directly tied to AI. This has led to a 'suspension of disbelief' among private investors who are not getting the same level of financial transparency as public market investors.

  • In 2025, Stripe reported $6.9 billion in net revenue and $1.2 billion in EBITDA.
  • In September 2025, Ramp announced $1 billion in annualized gross revenue.
  • In January 2026, Brex was valued at $5.15 billion when Capital One announced it would acquire the company.

The players

Stripe

A San Francisco-based payments company that helps merchants accept credit cards, process stablecoin transactions, and manage billing tasks. Stripe has achieved a $159 billion private market valuation.

Ramp

A New York-based corporate card company that has a $32 billion private market valuation, despite questions about its net revenue figures.

Brex

A corporate card rival to Ramp that had 30% less revenue than Ramp as of September 2025, but was valued at only $5.15 billion when acquired by Capital One in January 2026.

Chime

A digital bank that went public in June 2025 at a $25 billion valuation, but has since traded between $7 billion and $11 billion, well below its initial public trading price.

Klarna

A publicly traded buy-now, pay-later company based in Stockholm that has seen its market value plummet from a $46 billion private valuation in 2021 to just $6 billion currently.

What they’re saying

“They're not even in the zip code of what they'd trade at as public companies.”

— Michael Gilroy, Former general partner at Coatue, founding partner of Marathon (Forbes)

“There's definitely a suspension of disbelief, because many of these private investors aren't getting quarterly numbers from the companies they invest in. It's a bit of a blind box that they're investing in.”

— Annie Lamont, Cofounder and managing partner of Oak HC/FT (Forbes)

“I'm an investor in lots of companies that are not necessarily playing in AI, and even if they're doing really well, they just can't raise money right now.”
