#Uber will hit the public markets this morning with a valuation that could top $75 billion. The world's biggest ride-hailing business debuts weeks after Lyft, its smaller rival. Uber is far from making money with operating losses of $3 billion in 2018. This follows an operating loss of more than $4 billion in 2017. Still, not all investors are scared away from red ink. Some analysts predict Uber will eventually turn a profit.
