Why Uber is losing money and what it will take to become profitable

Uber is going public on Friday and it's valuation could top $90 billion. The world's biggest ride-hailing business is hitting the market just weeks after smaller rival Lyft. But Uber is far from making money. It reported an operating loss of $3 billion in 2018 after losing more than $4 billion the prior year. Some analysts predict it will become profitable eventually.
