Jeff Bezos' Amazon reached $1,500 a share Wednesday for the first time ever. Amazon's stock is up 27% in 2018 even though the broader market is about flat on the year.
The company's market value is now $718 billion, trailing only Apple (AAPL) and Google (GOOG).
Amazon recently surpassed Microsoft (MSFT), which is now in fourth place.
Amazon hit $1,000 a share last May and its stock boomed 73% in 2017. That helped Jeff Bezos become the world's richest person, topping Bill Gates. His wealth surpassed $100 billion in November.
Amazon's stock has raced out of the gate this year after reporting stellar earnings earlier this month.
The company announced a profit of nearly $2 billion, the largest in its history and the first time it topped $1 billion in a quarter.
