Tech billionaire Elon Musk said he would like Tesla to invest in his artificial intelligence company xAI.

While Musk is considering the relationship between several of his businesses, he said on X that he does not support a merger between Tesla and xAI.

“If it was up to me, Tesla would have invested in xAI long ago,” Musk wrote on X on Sunday. “We will have a shareholder vote on the matter.”

xAI is the company behind the controversial chatbot Grok, which is available on X and also used in Teslas delivered on or after July 12. Grok came under fire earlier this month for praising Adolf Hitler and making antisemitic comments.

The AI company apologized for the chatbot’s behavior, saying that a coding problem temporarily made Grok susceptible to extremist views posted on X.

Earlier, Grok had contradicted itself while sharing information about the deadly flash floods that killed at least 130 people in Texas this month. The bot blamed President Trump for the flooding, but then backtracked and understated the death toll.

Musk is scrambling to keep up in the AI race after helping launch OpenAI with Sam Altman in 2015, the company behind the wildly popular chatbot ChatGPT, which helped spur on the current AI craze. Musk left OpenAI in 2018 and is now entangled in legal battles with the company.

In March, xAI acquired X in an all-stock transaction that valued the artificial intelligence company at $80 billion and the social media platform at $33 billion.

Musk scored a victory for Grok on Monday, when xAI announced “Grok for Government” and a contract with the U.S. Department of Defense.

After a disruptive stint in the Trump administration that sent Tesla shares stumbling, Musk formally stepped down from his role in the federal government in May. He has since been feuding with the president, further risking Tesla’s reputation, according to some experts.

Tesla shares rose slightly Monday after Musk’s posts about Tesla’s possible investment in xAI. The shares have fallen more than 16% this year. The company’s profit plunged 71% in the first quarter.

Tesla delivered 384,122 vehicles in the second quarter through June, down 13% from 443,956 deliveries a year ago.

Its shares rose more than 1% Monday.

Elon Musk on Wednesday unveiled Grok 4, a new version of his X platform’s AI chatbot. The update comes a day after the bot posted antisemitic content on the social media network. 

Musk introduced the new model in a livestream on X late Wednesday, calling Grok 4 “the smartest AI in the world.”

“It really is remarkable to see the advancement of artificial intelligence and how quickly it is evolving,” Musk said, adding that “AI is advancing vastly faster than any human.”

He touted the model’s virtues, claiming that if it were to take the SATs, it would achieve perfect scores every time, and also outsmart nearly every graduate student across disciplines. 

“Grok 4 is smarter than almost all graduate students in all disciplines, simultaneously,” Musk said. “That’s really something.” 

Musk acknowledged that the pace of AI development is a little “terrifying.” The Tesla founder also said in a social media post on Thursday that the electric car maker’s vehicles will include Grok no later than next week. 

The release of the new model comes a day after Grok 3 made antisemitic remarks on X, including one in which it praised Adolf Hitler. The posts were later deleted. 

Musk’s xAI, the company that developed the chatbot, addressed the controversial remarks in a statement Wednesday. 

“We are aware of recent posts made by Grok and are actively working to remove the inappropriate posts. Since being made aware of the content, xAI has taken action to ban hate speech before Grok posts on X. xAI is training only truth-seeking and thanks to the millions of users on X, we are able to quickly identify and update the model where training could be improved,” the company said. 

Musk attributed Grok 3’s remarks to shortcomings in the AI’s ability to filter human input, writing on X, “Grok was too compliant to user prompts. Too eager to please and be manipulated, essentially. That is being addressed.”

Elon Musk has sold social media site X to his own xAI artificial intelligence company in a $33 billion all-stock deal, the billionaire announced on Friday.

Both companies are privately held, which means they are not required to disclose their finances to the public.

Musk said in a post on X that the move will “unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.” He said the deal values xAI at $80 billion and X at $33 billion. Musk, who serves as CEO of Tesla and SpaceX as well as an advisor to President Donald Trump, bought the site then called Twitter for $44 billion in 2022, gutted its staff and changed its policies on hate speech, misinformation and user verification and renamed it X.

He launched xAI a year later.

“xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent. This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach,” Musk wrote on X. “The combined company will deliver smarter, more meaningful experiences to billions of people while staying true to our core mission of seeking truth and advancing knowledge.”

It’s not clear if the move will change anything for X users — xAI already uses data from X user posts to train its artificial intelligence models and paying X users have access to its AI chatbot, Grok.
