BIG THINGS
1. Nubank’s $45B debut
The year’s next enormous fintech debut went off smoothly. Stock in Nubank opened trading today at $11.25, up 25% from its IPO price of $9. That figure dipped to $10.25 by late afternoon, but it still resulted in a $45 billion valuation for the Brazilian company, a huge leap from a $30 billion valuation on the private market just five months ago.
