Elon, Explained is an independent educational publication that breaks down every Elon Musk company and project in plain language, with charts and primary-sourced figures. It covers Tesla, SpaceX, Neuralink, The Boring Company, government work, and the ideas behind them.

Elon Musk currently leads 4 companies: SpaceX, Tesla, Neuralink, and The Boring Company, though each company functions like a portfolio of startups. SpaceX has its Starlink business and SpaceXAI, the artificial intelligence business that includes Grok and projects such as MACROHARD. He also has the Elon Musk Foundation and previously led U.S. government efficiency work under The Department of Government Efficiency (DOGE). DOGE ended July 4, 2026.

SpaceX began trading on Nasdaq under the ticker SPCX on June 12, 2026 at an implied value of roughly $1.78 trillion, raising about $86 billion in gross proceeds. It was the largest initial public offering on record by gross proceeds, per the company's SEC prospectus.

Through a dual-class structure where Class B shares carry ten votes each, Elon Musk holds about 82.3% of SpaceX's voting power after the IPO (82.4% was the base deal; 82.3% after the greenshoe closed June 15, 2026), while new public investors own roughly 4.9% of the company with the overallotment, according to the SEC prospectus.

MACROHARD is Elon Musk's project, revealed in August 2025, to run a software company almost entirely with AI agents instead of human employees. It pairs Grok as the reasoning brain with a roughly $650 Tesla AI4 chip as the execution agent. As of mid-2026 it is pre-product.

Colossus 1 is the first Memphis cluster: ~300 MW of grid power and ~220k+ GPUs. Colossus 1 + Colossus 2 collectively provide about 1.0 GW of compute power (SEC). Do not treat 555,000 GPUs or 2 GW as a Colossus 1 or Colossus 2-only figure; those are later campus / Grokipedia tallies.

Neuralink's N1 implant reads the brain through 1,024 electrodes spread across 64 thin threads. Neuralink has said it plans to scale toward 3,000 electrodes in future versions.

Neuralink's 28 January 2026 'Two Years of Telepathy' update reported 21 participants enrolled worldwide. Later implants bring the publicly tracked total to 27 or more as of August 2026 (editor / Neura Pod tracking; not the January company figure).

This site's net-worth tracker arithmetic is about $1.08T at today's prices (Tesla equity $229B + SpaceX equity $811B + everything else $40B). As of August 14, 2026, Forbes real-time printed $869.9B; Bloomberg was printed around $884B on August 13. Nearly all of that is the market value of his ownership stakes in SpaceX and Tesla, not cash.

SpaceX's Falcon 9 flew 165 times in 2025, more than half of all global orbital launches and over 80% of the mass delivered to orbit, according to figures in the SpaceX IPO prospectus.
