PayPal vs Stripe

PayPal was not originally called PayPal. Confinity — founded by Peter Thiel and Max Levchin — built software that could beam money between PDAs. At the same time, Elon Musk founded X.com, an online bank. In March 2000, they merged. The combined company was renamed PayPal in 2001, after a product Musk reportedly disliked. Musk would spend decades later trying to revive the X name for Twitter.

While Elon Musk was on his honeymoon in October 2000, the board voted to remove him as CEO and replace him with Peter Thiel. Among the complaints: Musk wanted to migrate the entire payment platform from Unix to Windows servers — a decision engineers considered technically catastrophic. Musk was furious. The company kept Unix. The episode foreshadowed Musk's combative relationship with boards for the next two decades.

PayPal went public in February 2002. Eight months later, eBay acquired it for $1.5 billion. The group of early PayPal employees — Musk, Thiel, Levchin, Reid Hoffman, David Sacks, Keith Rabois — became known as the "PayPal Mafia." They went on to found or fund LinkedIn, YouTube, Yelp, Palantir, SpaceX, and dozens of other companies. No single company has produced more consequential founders than PayPal.

After years of activist investor pressure, eBay spun off PayPal as an independent publicly traded company in July 2015. PayPal's market cap at separation was $46 billion. eBay's was $33 billion. The subsidiary had become more valuable than the parent — a pattern that would repeat across corporate history.

PayPal reached a peak market cap of over $360 billion in July 2021. Then rising interest rates, intensifying competition from Apple Pay, Stripe, Cash App, and Venmo eroded its edge. The stock fell over 75% from its peak by 2022 — one of the most dramatic collapses of any major U.S. fintech. Under new CEO Alex Chriss, appointed in 2023, PayPal pivoted aggressively toward AI-powered checkout tools and merchant services, attempting to recapture relevance in a payments landscape it once dominated.

Patrick Collison was 22 and John Collison was 19 when they founded Stripe in 2010. Their pitch was simple: accepting payments online required integrating with banks, payment processors, and fraud systems — a process that took weeks and required a lawyer. Stripe reduced it to seven lines of code. PayPal had been trying to solve this problem for a decade. Two brothers from Dromineer, a village in rural Ireland with a population of a few hundred people, solved it in a weekend.

Stripe was accepted into Y Combinator in 2011. Peter Thiel, Elon Musk, and Sequoia Capital all invested in the seed round. Thiel later said it was one of the most obvious investments he had ever seen — the problem was real, the solution was elegant, and the founders were exceptional. The initial valuation was $100 million. Within a decade it would be $95 billion.

In March 2021, Stripe raised funding at a $95 billion valuation — making it the most valuable private company in the United States. The Collison brothers, both still in their early thirties, were each worth approximately $11 billion. Neither showed any interest in going public. Patrick Collison described Stripe's ambition as "raising the GDP of the internet" — a company so deeply embedded in global commerce that its health would mirror the health of the digital economy itself.

In 2023, Stripe laid off 14% of its workforce and raised new funding at a $50 billion valuation — a 47% cut from its 2021 peak. The company acknowledged it had over-hired during the pandemic boom. Critics questioned whether Stripe could maintain its dominance against PayPal, Adyen, and a growing field of competitors. The Collisons kept working.

In February 2026, Stripe ran a tender offer valuing the company at $159 billion — surpassing its 2021 peak and making it the most valuable fintech company in the world. Total payment volume in 2025 hit $1.9 trillion, up 34% from 2024 — roughly 1.6% of global GDP flowing through Stripe's infrastructure. Free cash flow was $2.2 billion. When asked about an IPO, John Collison said: "For us right now, an IPO would be a solution in search of a problem." The two brothers from rural Ireland were running one of the most important financial infrastructure companies on earth, still privately owned, still not in any rush.
