Tesla also said Musk's other companies — mainly SpaceX and xAI Holdings — now account for most of his wealth and therefore will command most of his attention unless Tesla pays him more."A majority of Mr.

Musk's wealth is now derived from other ventures outside of Tesla, and he has more attractive options today than ever before," the xy said.

The pay package of up to 423 million s is necessary, it added, to prevent Musk from "prioritizing other ventures."It will be up to holders to apve the package, of course.

But the xy highlights the surging valuations of Musk's and the competing interests of xAI, SpaceX and Tesla.Until last year, the vast majority of Musk's wealth came from his Tesla stock.

The Bloomberg Billionaires Index pegs Musk's wealth at $385 billion, while Forbes estimates his wealth is at $436 billion.

SpaceX is planning an insider sale that would reportedly value the company at $400 billion, nearly double its valuation last year.

At the $400 billion valuation, Musk's stake would be worth $170 billion — more than the value of his current Tesla stake.xAI's valuation has grown even faster, from $80 billion at the start of the year to a potential $200 billion in a new fundraising round.

Musk owns more than 50% of the company, putting his stake well over $100 billion.Together, Musk's stake in xAI and SpaceX are now worth nearly twice as much as his Tesla s.

Added to his stakes in Neuralink — valued at around $9 billion — and his other companies, his private company wealth eclipses his Tesla wealth.Of course, that may not be for long.

If he is awarded the 423.7 million s of restricted stock in the new 2025 compensation plan, and if Tesla hits its target valuation of $8.5 trillion, Musk's Tesla s would be worth over $2 trillion.
