Elon Musk says special committees at SpaceX and Tesla are exploring a merger, and if the deal closes, the single-letter stock ticker X—vacant since Nippon Steel swallowed U.S. Steel last year—could end up back on the board, and the only people sweating it are the same financial press that spent years cheering every blank-check SPAC Wall Street's darlings cranked out.

Why it matters: Concentration of corporate power only seems to alarm the establishment when they don't hold the reins. Musk runs both companies, has an obsession with the letter X stretching back to his early X.com days—the domain he bought back in 2017—and investors already see the writing on the wall. "The merger has a ways to go, but if it closes, nobody should be surprised to see X back on the tape," Dave Mazza, chief executive of Roundhill Investments, told Bloomberg, as reported by TNW. "It's entirely on brand."

Musk called the potential merger "a good idea" but said no terms have been agreed and a deal may never happen. Only five single-letter U.S. tickers remain free—K, N, I, X, and Y—according to Bloomberg. The X symbol has sat unused since Nippon Steel's acquisition of United States Steel completed last year, a foreign takeover of an American industrial icon that drew far less hand-wringing from the financial commentariat than Musk's ambitions ever seem to.

Some investors argue a merged entity would need a new identity regardless. "Tesla still makes people think cars, and SpaceX makes people think rockets," Haris Khurshid, chief investment officer at Karobaar Capital, told TNW. Max Gokhman of Franklin Templeton Investment Solutions was more blunt: "X will probably mark that spot. That would be the most Musk thing ever."

Meanwhile, the Philadelphia Inquirer reported on a parallel story of Musk saying one thing and doing another: he publicly agreed with Anthropic CEO Dario Amodei's call for the AI industry to "slow down"—then kept racing. Anthropic, OpenAI, Google, and SpaceX have all launched new, more capable AI models since that public slowdown compact, and Anthropic just filed paperwork for what could be the largest IPO in history, telling investors it plans to spend hundreds of billions on compute and infrastructure.

Connor Leahy, U.S. director of the nonprofit ControlAI, cut through the noise: "Would you believe this if an oil company said it? Watch the hands, not the mouth." Sen. Elizabeth Warren sent a letter to Amodei asking him to reconcile his warnings about AI's dangers with his drive to raise money on the stock market.

The pattern is clear: public calls for restraint, private acceleration toward dominance. The difference is that when Wall Street does it, it's called strategy. When Musk does it, it's called a threat.

The open question isn't whether Musk will consolidate—it's whether the same rules that applied to every SPAC-happy financier and AI-lobbying tech giant will apply to him, too.
