I'll comment anyways even if I only read the first paragraph.
As of SEPTEMBER 2021, Musk didn't had this kind of money in his cloud wallet.
He was awarded a $56 billion pay package in 2018. (You forgot the dates, but doesn't matter)This compensation package was designed to incentivize Musk to achieve a series of ambitious performance targets for Tesla, including increasing the company's market capitalization and revenue growth.
Paypackage was structured in such a way that Musk would receive STOCK options over a PERIOD of 10 years with each tranche of options vesting only if Tesla met specific FINANCIAL goals and market capitalization"milestones". If all targets were met, Musk stood to receive BILLIONS of dollars in stock options.
Present world, Musk has achieved several of the milestones outlined in the PAY PACKAGE, leading to a significant increase in Tesla's market capitalization and stock price. This has resulted in Musk's net worth increasing substantially, making him one of the richest individuals in the world. Tesla current stock price is at around $178 it's down since the last few days I've checked where it was up over 3%.
Overall, the $56 billion pay package for Elon Musk was tied to his PERFORMANCE and the success of Tesla, and the significant increase in Tesla's valuation has led to Musk's WEALTH GROWING substantially.
IT WOULD BE NICE if we all can borrow Musk's neuron cells!
