Fintech Highlights — August 2026

The Stripe-PayPal deal became real, and Stripe kept shopping. 

After months of speculation, Stripe and Advent's joint offer for PayPal was confirmed at over $53 billion — the largest fintech acquisition ever, and a rare case of a venture-backed company bidding for an S&P 500 member, backed by $50 billion in committed financing. In the same stretch, Stripe confirmed it was acquiring OpenRouter, the AI model marketplace, for $7.5 billion — about 5.4x what OpenRouter was worth at its Series B just three months earlier. Stripe CEO Patrick Collison framed it as a bet that "tokens are becoming increasingly fungible with money," positioning Stripe at the center of AI spending the way it already sits at the center of payments.

Prediction markets kept overtaking crypto as Robinhood's growth engine. 

Robinhood's Q2 revenue hit $1.31 billion, up 32% year-over-year, with prediction-market revenue rocketing over 10x to $156 million — now bigger than its crypto revenue ($100 million, down sharply from a year ago). Rothera, Robinhood's prediction-market joint venture with Susquehanna launched in June, has already traded over 3.5 billion contracts.

Klarna hit a rough patch. 

Shares fell 20% after the company cut its full-year outlook, citing weakness in its largest market, Germany, alongside news that its longtime finance and marketing chiefs would depart early next year. Klarna still posted 27% revenue growth for the quarter and swung to a $27 million operating profit — the guidance cut was about the road ahead, not the quarter just finished.

Also this month: 

• Vanguard agreed to acquire RIA software provider Altruist for $4.6 billion in cash;
• Kalshi tacked another $120M onto its Series F (now at a $22B valuation) and is already back in market for a Series G; and
• Revolut pushed its valuation to $115 billion in a new secondary sale, up from $75 billion a year earlier.
