Silicon Valley billionaire Elon Musk said he has relocated to Texas from California as he wanted to focus more on Tesla Inc's new electric car plant and his SpaceX venture in the Lone Star state.
Musk confirmed the move in an interview with Matt Murray, the Wall Street Journal's editor-in-chief.
"The two biggest things that I got going on right now are the Starship development in South Texas and then the big new US factory for Tesla," the 49-year-old said.
"It wasn't necessarily a great use of my time here [in California]".
Texas might potentially offer some tax reprieve for the world's second richest man as it does not collect personal income tax, while California has some of the highest state tax rates in the United States.
An over 670 per cent jump in Tesla shares this year has boosted Musk's net worth from $27 billion (€22.3 billion) to $155 billion (€128.1 billion) , just behind Amazon.com Inc's Jeff Bezos, according to the Bloomberg Billionaires Index.
In a conversation touching a wide range of topics including government intervention, technology companies and corporate policy, Musk criticized CEOs of other US companies for not focusing enough on their products.
"If you find yourself spending a lot of time giving presentations and reviewing spreadsheets, you're barking up the wrong tree," Musk said.
The billionaire also compared himself to a war general, saying: "If you think about war, do you want the general in some like ivory tower or on the front lines? The troops are going to fight a lot harder if they see the general on the front lines."
Musk said tech companies in Silicon Valley had too much influence on the world and predicted a decrease in their power.
On Tesla's move to raise $5 billion (€4.1 billion) in capital, he said: "We thought we can retire a lot of the debt and increase the security of the company, have more of a war chest."
Musk has earned Tesla stock options related to his 2018 pay package that are currently worth almost $20 billion (€16.5 billion).
Tesla shares were up 0.6 per cent in trading after the bell.
