Elon's Universe

SpaceX and Tesla are the two biggest pieces, but Elon Musk's world now stretches from a brain implant lab to a tunnel company to a bank account inside a social network — and in 2026 the pieces started fusing together. Here is every piece, where it stands, and how they connect.

Last reviewed October 31, 2026. Where sources disagree, we say so.

The map of the empire, October 2026

Until early 2026 these were separate companies that happened to share a founder. That is no longer true. On February 2, 2026 SpaceX acquired xAI — and with it X — in an all-stock deal that valued SpaceX at $1 trillion and xAI at $250 billion, the largest merger ever recorded. CNBC SpaceX then went public on June 12, 2026 as SPCX on Nasdaq. In October 2026, SpaceX and Tesla formed special board committees to study merging the two remaining giants. TechCrunch

xAI and Grok: from startup to the AI arm of SpaceX

xAI was incorporated in March 2023 and announced that July with Musk and eleven researchers. In three years it raised roughly $50 billion, built two of the largest AI supercomputers on Earth, absorbed X, bought the coding tool Cursor for $60 billion, and was itself absorbed by SpaceX.

Grok, version by version

Grok had 117 million monthly users and 1.9 million paying subscribers as of March 2026, per the SpaceX S-1. S-1 analysis On October 12, 2026 everything was bundled into The X Subscription — Grok, Grok Bot agents, Cursor and X Premium in one plan from $8 a month. PYMNTS

Colossus: the computers behind Grok

Colossus 1 in Memphis was built in 122 days and switched on in September 2024 with 100,000 Nvidia H100s. By the time of the S-1 it held 220,000+ GPUs drawing more than 300 MW. Colossus 2 across the state line in Southaven, Mississippi was deployed in 91 days and is sized at roughly a gigawatt, with a third building targeting ~2 GW total. Colossus overview

The twist of 2026: much of that compute is rented out. Anthropic agreed in May 2026 to take all of Colossus 1's capacity (reported at ~$1.25B a month), and Google agreed in June to pay $920M a month for 110,000 GPUs — disclosed in an SEC filing days before the IPO. Euronews The S-1 showed why the cash matters: the AI segment lost $6.4 billion on $3.2 billion of revenue in 2025. S-1 analysis

The gas turbines powering the sites are the subject of a Clean Air Act lawsuit by the NAACP and the Southern Environmental Law Center; on October 31, 2026 a federal judge refused to dismiss it. TechCrunch

The talent exodus and rebuild

Every one of xAI's eleven non-Musk co-founders had left by March 28, 2026 — Igor Babuschkin (Aug 2025), Jimmy Ba and Tony Wu (Feb 2026), Toby Pohlen, Guodong Zhang, Zihang Dai and finally Ross Nordeen. CFO Anthony Armstrong left in April 2026. Musk posted that “xAI was not built right first time around” and said it was being rebuilt from the foundations; ex-Starlink VP Michael Nicolls now runs the AI unit and SpaceX CFO Bret Johnsen runs its finances.

X, X Money and the “everything app”

Musk closed the $44 billion Twitter purchase on October 27, 2022, renamed it X, moved it to Texas, and has spent four years turning it into a WeChat-style everything app. Linda Yaccarino was CEO from June 2023 until she resigned on July 9, 2025; no successor was named, and since February 2026 X has lived inside SpaceX's AI division. X Corp

X Money — a bank account inside a social network

Announced with Visa in January 2025, X Money finally launched publicly on July 27, 2026 for US Premium subscribers: an FDIC-insured deposit account at Cross River Bank, peer-to-peer payments, a virtual and metal X Card on Visa with Apple Wallet support, up to 6% APY for Premium+ and 3% cash back. 9to5Mac

The Grok movie: an AI-made “Odyssey”

In July 2026 — the same month Christopher Nolan's The Odyssey became a box-office hit — Musk said Grok Imagine would produce a full-length, “historically accurate” AI-generated film of Homer's epic by the end of 2026. Hollywood Reporter

On October 23, 2026 Grok Imagine released “Episode 1”: a seven-minute opening made with Wonder Studios and director Dev Walker. TechCrunch found the visuals better than expected but the dialogue stilted; no release schedule for further episodes has been given, and the feature-length promise is still open. TechCrunch

Terafab: the most ambitious chip factory ever proposed

Terafab is a joint venture of Tesla, SpaceX and xAI to build chips at a scale no company has attempted — launched on March 21–22, 2026 at Austin's old Seaholm Power Plant, where Musk called it “the most epic chip building exercise in history by far.” SiliconANGLE

Timeline

Samsung and TSMC are not Terafab partners in any source we reviewed; Tesla has a separate Samsung supply deal for its AI6 chip. Headline cost figures vary widely by phase and source.

Neuralink

Founded in 2016, Neuralink implanted its first human patient, Noland Arbaugh, on January 29, 2024. By January 28, 2026 the company reported 21 participants enrolled worldwide with “zero serious device-related adverse events,” with trials in the US, Canada (Toronto) and the UK (UCL).

• Steve Davis — SpaceX employee #14 in 2003, Boring's president since 2018, and the de facto leader of DOGE in early 2025.

Elon Musk in 2026

Musk became the world's first dollar trillionaire on June 12, 2026 — SpaceX's IPO day — fell back below the line in July as the stock slumped, and crossed it again on October 5, 2026 at $1.04 trillion by Bloomberg's count (Forbes puts him near $1.1T). More than 98% of that is his SpaceX and Tesla stakes. Bloomberg

Titles

Tesla CEO and product architect. SpaceX founder, CEO, chief engineer and chairman. Founder and CEO of the AI division (xAI → SpaceXSI). Chairman and CTO of X. Founder of The Boring Company. Co-founder and chairman of Neuralink.

Politics, briefly and factually

Musk led the Department of Government Efficiency from January 20 to May 30, 2025, feuded publicly with President Trump that June, announced an “America Party” in July that was never filed, and reconciled with Trump at Charlie Kirk's memorial in September 2025. He is the largest known donor of the 2026 midterm cycle at roughly $443 million per Forbes. Forbes

The share gifts: Shotwell’s 2 million and Musk’s pledge

Two of the most talked-about stories of autumn 2026 are gifts of SpaceX stock to children through the new federal “Trump Accounts.”

Gwynne Shotwell: more than 2 million shares

On July 6, 2026 SpaceX president Gwynne Shotwell and her husband Robert pledged a share of their own SpaceX stock to more than 2 million children aged 11–17 in lower-income areas — a gift valued around $330 million. On October 30, 2026 Shotwell said the shares were moving into escrow for distribution in December to children in ZIP codes with median family income of $57,000 or less; a second gift for children of overseas military families, foster children and central-Texas counties is to follow “in coming weeks.” Reuters

Elon Musk: a share for every American child, next year

On October 19, 2026 Musk said on X that he will give one SpaceX share to every child in America in 2027 through Trump Accounts — roughly 60 million children, which at October prices would be a gift of more than $10 billion. The mechanism has not been announced; Treasury rules route such gifts through a charity, and Musk's own shares are locked up until about June 2027, which fits the “next year” timing. Axios

The talent: who actually runs all this

Musk's companies are famous for his presence, but each is run day to day by long-tenured operators. Here are the names worth knowing (✗ marks departures).

SpaceX

Tesla

Everywhere else

Next: a SpaceX–Tesla merger?

On October 20, 2026 both boards formed special committees of independent directors to study a merger, at what Musk described as shareholders' request. He recused himself as “a conflicted party,” and named AI software, robotics, Starmind orbital data centers and Terafab as the synergies. TechCrunch

The hurdle is on Tesla's side: approval needs a yes from 50% of all outstanding shares — about 1.98 billion votes — which Musk called “quite a high hurdle.” Bloomberg has noted the committees' members are close to Musk. No terms have been agreed. 24/7 Wall St
