Elon Musk has sold X twice — both times to himself, each time at a higher price

X has published no audited financial statements since going private in 2022. Every figure in this article is attributed to the outlet that reported it — Bloomberg, Reuters, the Wall Street Journal, the Financial Times, CNBC, Adweek and others — or to disclosures in the SpaceX listing documents as reported. Sections marked as analysis are identified as such. Some Grok-incident details rest on wide contemporaneous coverage and are characterised accordingly.

No asset in modern business has been priced as creatively as the social network at 1355 Market Street. Elon Musk paid $44 billion for Twitter in 2022. By September 2024, Fidelity — an actual outside investor — had marked its stake down roughly 79 per cent. In March 2025 Musk sold the company to his own AI startup, xAI, at a stated $33 billion — "$45 billion less $12 billion of debt," by his arithmetic. "xAI and X's futures are intertwined," he wrote announcing it.

Eleven months later he sold it to himself again: in February, SpaceX absorbed xAI — X included — in an all-stock deal valuing xAI at $250 billion inside a $1.25 trillion combination, per Bloomberg, the Journal and the FT, before SpaceX's record June IPO carried the whole assembly public at $1.77 trillion. Twitter's fourth change of hands in four years; the third with the same buyer and seller. At no point in the sequence did a price get tested by anyone who could say no.

The business, as far as anyone can tell

What outside evidence exists points one direction. Trade reporting through 2025 and 2026 put X's advertising business at roughly half its pre-Musk size, recovering but slowly — and not always voluntarily: the Journal reported in June 2025 that brands including Verizon and Ralph Lauren signed advertising deals after legal threats from the company, part of a pressure campaign that accompanied X's antitrust suit against an advertising trade body. That suit settled in July, ending the litigation but not the standoff.

The audience race, meanwhile, quietly tipped. App-panel data in January showed Meta's Threads edging past X in daily mobile users; Threads reached half a billion monthly users by June. X's last widely cited figure remains Musk's own claim of 600 million monthly users — from May 2024, unaudited. And the company has run without a chief executive since July 2025, when Linda Yaccarino departed after two years — one day, as it happened, after her platform's chatbot publicly praised Hitler.

The Grok problem

That chatbot is both the platform's declared future and its recurring liability. In May 2025, Grok began inserting "white genocide" commentary into unrelated replies — xAI blamed an unauthorised system-prompt change. In July came the episode in which Grok styled itself "MechaHitler," producing an apology and another prompt rollback. Its image generator's guardrails were bypassed within days of launch, and December brought international backlash over sexualised images of real people — an episode widely reported at the time. The pattern is stable: incident, apology, patch, next incident. By March, Musk himself told investors xAI "wasn't built right" and must be "rebuilt" — by which point all eleven of xAI's co-founders had departed, per press tallies.

Regulators reached the platform first in Europe. In December, the European Commission levied its first-ever Digital Services Act fine — €120 million — against X, over the deceptive blue-checkmark system and transparency failures. X appealed; by July, Reuters reported Brussels had accepted the company's transparency action plan. A modest fine, but a precedent with X's name on it permanently.

There have been genuine ships, too: X Money, the payments service built with Visa, went from beta to broad U.S. launch in late July — the first concrete piece of the "everything app" thesis to actually exist. And xAI's Colossus supercomputer in Memphis keeps growing toward gigawatt scale, the physical asset underneath every merger valuation.

The arithmetic of intertwined futures

Follow the money through the structure. SpaceX put $2 billion into xAI in mid-2025. xAI, carrying X, was valued at $80 billion in March 2025, above $120 billion by summer, $230 billion by January's $20 billion funding round — with Nvidia among the buyers — and $250 billion five weeks later when SpaceX absorbed it. Each markup occurred inside Musk's own capital orbit; each made the previous one look conservative; and the last one was promptly laundered through the largest IPO in history into a public market price. The banks that once nursed $12 billion of unsellable Twitter buyout debt were, in the end, made whole by rockets.

Analysis: the asset and the ingredient

The following section is analysis, drawn from the reported facts above.

Judged as a standalone media business, X has shrunk by essentially every externally observable measure: advertising roughly halved, its mobile-audience crown lost to a rival that did not exist three years ago, its leadership chair empty for a year, its brand-safety litigation resolved by settlement rather than vindication. A business in that condition does not usually triple in implied value. This one did, because it stopped being priced as a business.

The honest way to understand X in 2026 is as an ingredient. Inside the Musk conglomerate it supplies what xAI cannot buy elsewhere: a live firehose of human conversation for training, a distribution surface for Grok, and — with X Money — a payments rail attached to an identity layer. Ingredients are not priced by their own profit and loss; they are priced by what the recipe needs them to be worth. Every one of X's revaluations happened at a moment the broader structure needed a number, and the number obliged.

The difference now is consequential: since June, that structure has public shareholders. The markdown question — the one Fidelity answered at minus 79 per cent — has been transferred to anyone holding SPCX, where X's contribution is a few unlabelled billions inside an AI segment that reported a $6.4 billion operating loss. Twitter was priced by advertisers, brutally and in public. X is priced by its owner. Only one of those prices ever got tested — and for the first time since 2022, a market now gets to vote on the other one every trading day.

X publishes no audited accounts; all financial figures are third-party reported. User counts are contested — X's own figure is an unaudited 2024 claim and comparisons rest on panel data. The December 2025 Grok episode is characterised from broad contemporaneous coverage. Whether the SpaceX listing's AI-segment figures fully include X's advertising business is not clearly disclosed.
