# QUICK SPARK: Elon Musk Loses $80 Billion In A Single Week

The world’s richest person, **Elon Musk**, is ending the week $80 billion poorer, extending a wealth wipeout that began in mid-June after he became the world’s first trillionaire.

Musk started the week with a net worth of $792 billion, according to the Bloomberg Billionaires Index.

By Friday afternoon, his fortune had fallen to $712.5 billion, based on Forbes estimates.

That marks an $80 billion decline in just one week.

**Tesla Inc.** (NASDAQ:TSLA) accounts for only part of the damage.

Musk owns close to 11% of the carmaker, which has fallen about 19% this week after a second-quarter earnings miss.

The rest is SpaceX.

**Space Exploration Technologies Corp. (**NASDAQ:SPCX), in which Musk holds a 38% stake including options, is down about 9% this week. The company went public on June 12 at a valuation near $2 trillion.

The shares have roughly halved since.
