Uber confidentially files paperwork for IPO

Uber filed paperwork confidentially this week for its initial public offering, The Wall Street Journal reports.

Why it matters: Private financing has outpaced IPO fundraising in tech since the '90s, per a previous Axios report. Now, both Uber and Lyft's IPOs are expected to be the largest among the many companies in Silicon Valley that are aiming for 2019 stock market debuts.
