New York City Mayor Zohran Mamdani used SpaceX's historic IPO — and founder Elon Musk's newly minted status as a trillionaire — to push policy.
"Reason #1,000,000,000,000 why we should tax the rich," Mamdani wrote on X in response to Musk becoming the world's first trillionaire on Friday.
Musk reached the financial milestone after SpaceX stock popped upon hitting the market on Friday, trading at $150 per share, above the company's initial offering of $135.
Already the world's richest man, the windfall put Musk leagues ahead of the next richest person, Google's Larry Page, who now has a quarter of Musk's wealth.
Mamdani's response was in line with his politics. The progressive New York City mayor campaigned on taxing the rich, and the city's new pied-à-terre tax on multimillion-dollar second homes sparked backlash from some rich residents.
Musk has spoken out against Mamdani and backed his challenger, Gov. Andrew Cuomo, in the New York mayoral race last year.
