Daily Digit is the story behind the numbers that make our world work. Today we’re looking at what the incredible growth of Amazon could mean for two of Jeff Bezos’s earliest supporters — his mother and stepfather. According to a recent analysis from Bloomberg, the $245,573 investment made by Jackie and Mike Bezos in 1995 could be worth nearly $30 billion today. Although the elder Bezoses haven’t disclosed their holdings since 1999, it’s possible they’ve seen a 12 million percent return on their initial investment, assuming they’ve held on to their stock. As Amazon approaches a $1 trillion market cap, Jeff Bezos remains the world’s richest man — and he’s brought his parents with him.
