Musk’s foundation, boasting a substantial $7 billion in assets, has the potential to make a significant difference. However, a New York Times investigation alleges Musk failed to meet the U.S. charity tax law's requirement of distributing at least 5% of his foundation's endowment annually. In comparison, Musk's foundation reportedly distributed only $160 million in 2022, significantly less than the Bill & Melinda Gates Foundation's planned $8.6 billion in donations for 2024 alone, with a strategyto spend down its entire $67 billion endowment within the next two decades.
