Elon Musk is a well-known entrepreneur and business magnate, whose name is often associated with companies that are at the forefront of innovation in technology and energy. All these businesses made him the richest person in the world, with his wealth peaking at $340 billion in November 2021. Here’s a brief overview of the companies owned by Elon Musk:
Tesla Inc.

Tesla is a leading electric vehicle (EV) manufacturer founded in 2003. The company’s mission is to accelerate the world’s transition to sustainable energy, and it has been successful in doing so with its range of electric cars, solar panels, and energy storage systems. Tesla’s market capitalization has soared in recent years, and it is currently one of the most valuable car companies in the world. Everyone knows who owns Tesla, but Elon Musk did not incorporate the company. It was incorporated on July 1, 2003, as Tesla Motors, Inc., by Martin Eberhard and Marc Tarpenning. In February 2004, the company secured $7.5 million in series A funding, with Elon Musk contributing $6.5 million of that amount. This made him the largest shareholder in the company.
SpaceX

SpaceX, or Space Exploration Technologies Corp., was founded by Musk in 2002 with the goal of reducing the cost of space transportation, and eventually enabling the colonization of Mars. The company has developed several successful rockets and spacecraft, including the Falcon 9, Falcon Heavy, and Dragon. SpaceX has also launched several missions to the International Space Station (ISS) in partnership with NASA.
SpaceX has accomplished numerous milestones in space exploration. Among these are being the first private company to develop a liquid-propellant rocket that achieved orbit, launching, orbiting, and recovering a spacecraft, sending a spacecraft to the International Space Station, achieving vertical propulsive landing of an orbital rocket booster, reusing such a booster, and sending astronauts to orbit and to the International Space Station. Furthermore, Falcon 9 rockets developed by SpaceX have flown and landed more than a hundred times.
The Boring Company

Founded by Musk in 2016, The Boring Company aims to create an underground transportation system to alleviate traffic congestion in major cities. The company has developed a tunnel boring machine called the “Godot” and has completed a test tunnel in Los Angeles. The Boring Company is also working on a high-speed tunnel system known as the “Loop” that would transport passengers between cities and airports at speeds of up to 150 miles per hour.
Neuralink

Neuralink is a neurotechnology company owned by Elon Musk. It was founded in 2016 with the mission to develop implantable brain-machine interfaces (BMIs) that can help treat neurological disorders and eventually merge human consciousness with artificial intelligence. Neuralink has developed a device called the “Link” that can be implanted in the brain to record and stimulate neural activity.
According to Neuralink, they have developed a surgical robot that can swiftly implant numerous flexible probes into the brain. This innovation may mitigate issues related to tissue damage and longevity that are associated with larger and more rigid probes. The robot is equipped with an insertion head featuring a 40 μm diameter needle composed of tungsten-rhenium, engineered to attach to insertion loops, inject individual probes, and penetrate both the meninges and cerebral tissue. It has the ability to insert up to six wires (equating to 192 electrodes) in a minute.
SolarCity

SolarCity was a solar panel installation company founded by Musk’s cousins in 2006. Musk became the chairman of the company in 2008 and eventually merged it with Tesla in 2016. SolarCity’s mission was to make solar energy more accessible to homeowners and businesses, and it became one of the largest solar panel installation companies in the United States before the merger.
Open AI

OpenAI is an artificial intelligence research laboratory consisting of a team of researchers and engineers dedicated to advancing AI in a safe and beneficial way for all of humanity. It was founded in 2015 by a group of prominent technology industry figures, including Elon Musk and Sam Altman, with a focus on developing advanced artificial intelligence in a way that is transparent, safe, and beneficial to society.
OpenAI is known for its research in a wide range of fields, including natural language processing, reinforcement learning, robotics, and computer vision. The organization has also created a number of tools and platforms for developing AI applications, such as the GPT series of language models and the OpenAI Gym, a toolkit for developing and comparing reinforcement learning algorithms.

Twitter was founded in 2006 by Jack Dorsey, Biz Stone, and Evan Williams. It went public in 2013 and is currently headquartered in San Francisco, California. Twitter’s primary revenue stream comes from advertising, with companies paying to promote their products or services through promoted tweets, accounts, or trends.
In April 25, 2022, it was reported that Elon Musk, CEO of SpaceX and Tesla, had agreed to buy out Twitter for $44 billion, marking one of the largest deals to take a company private. However, on July 8, Musk terminated the agreement, causing Twitter’s shares to decline and leading the company officials to file a lawsuit against Musk in the Chancery Court of Delaware on July 12. Later, on October 4, Musk confirmed that he still intended to purchase the company for the previously agreed amount of $44 billion, or $54.20 a share. The agreement was finalized on October 27.
Final Thoughts
Elon Musk has founded or co-founded several companies that are at the forefront of innovation in technology and energy. These companies are not only changing the way we think about transportation and energy, but they are also pushing the boundaries of what is possible in space exploration and neuroscience. With his vision and drive, Musk is poised to continue leading the charge in these industries for years to come.
