The public debut of SpaceX on 12 June created the world’s first trillionaire, as Elon Musk’s fortune surged beyond $1.2 trillion—equivalent to more than 3% of U.S. GDP. The aerospace company, which reported revenue of just $18.7 billion alongside a $4.9 billion loss in 2025, commanded a market valuation above $2 trillion. This gap between financial performance and market capitalisation eclipses historical benchmarks: the wealth of John D. Rockefeller peaked at roughly 1.5% of U.S. output, and Andrew Carnegie’s steel fortune, adjusted, would be a fraction of Musk’s stake.

The mechanism driving the valuation is less a balance sheet than a personality cult summed up by the investor shorthand “In Musk We Trust.” Markets bet on his capacity to bend the future, echoing Henry Ford’s transformation of industrial capitalism a century ago. But where Ford promised mass prosperity, Musk’s narrative sells technological sovereignty, a vision critics across Europe label “Muskism”—a blend of libertarianism, market fundamentalism, and digital authoritarianism that promises autonomy while deepening dependence on his platforms.

The concentration of wealth has drawn warnings from multiple angles. In India, billionaire Mark Cuban argued that the real problem is not Musk’s riches but the inability of ordinary workers to accumulate appreciating assets; he advocated broad-based employee stock ownership. Meanwhile, Latin American observers resurrected Plato’s ancient injunction that in a just republic, no citizen should hold more than four times the wealth of the poorest. Musk’s net worth, estimated at five million times the average U.S. family’s, breaks that bound by orders of magnitude. Political shockwaves have followed: after a tumultuous stint leading Washington’s Department of Government Efficiency and a public break with Donald Trump over fiscal policy, Musk founded the America Party in July 2025 with the stated aim of disrupting the two-party system.

The next factual milestone is the 2026 U.S. midterm elections, where the America Party’s capacity to attract votes or funding will test whether Musk’s wealth can translate into durable political influence. Beyond the ballot box, the performance of SpaceX and Tesla will determine if the market’s extraordinary faith endures or reflects what the former Greek finance minister Yanis Varoufakis calls an echo of the dot-com bubble.
