Elon Musk could try to run three major companies at once — the last known CEO who did it is now an international fugitive
Elon Musk's bid to acquire Twitter might have an undesirable side-effect for the billionaire: adding yet another large company to his jam-packed schedule.

The Tesla and SpaceX CEO has offered to buy every Twitter share he doesn't already own — 90.8% of the company — in a deal worth roughly $43 billion, according to a regulatory filing disclosed on Thursday. The deal would add another of the world's largest companies to Musk's ownership portfolio: Tesla and SpaceX are already a trillion-dollar company and a multibillion-dollar company, respectively.

Musk also owns two smaller start-up ventures, Neuralink and The Boring Company.

Even if Musk successfully purchases Twitter and declines to name himself CEO, it's highly likely that he'd want to influence the company's day-to-day operations, potentially leading to a serious time crunch for the world's richest person. And while running three businesses simultaneously isn't unheard of — Musk, who's Neuralink's CEO, already does it — leading three of the world's largest companies all at once is nearly unprecedented.

Here's some good news for Musk: It's been done before. The bad news is that the most recently known executive to attempt the feat was none other than Carlos Ghosn, the former CEO of Nissan and Renault, and ex-chairman of AvtoVaz and Mitsubishi.

Ghosn actually held top roles at all four companies for a spell, and was running three of them in 2018 when he was arrested in Japan over allegations of financial misconduct. Ghosn infamously fled to Lebanon, which has no extradition treaty with Japan, where he resides today as an internationally wanted fugitive.
