Elon Musk’S Grok Ai Is Spamming X Users About South African Race Relations Now, For Some Reason

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More. Elon Musk’s AI startup xAI has sought to compete with category leaders like OpenAI, Google, Microsoft, and Anthropic for individual consumers and app developers as customers, but a new development with its signature chatbot assistant Grok seems unlikely to help it win market share.Today, users on Musk’s social network X (formerly Twitter, now a subsidiary of xAI) where Grok is built-in as an AI bot that can be called in to reply to user conversations with facts and information, observed that Grok began responding to their questions and requests with bizarre rants about South Africa’s racial climate and conflicts thereof — even when the conversation had nothing to do with these subjects.As New York Times visual investigative journalist Aric Toler wrote on X earlier today: “I can’t stop reading the Grok reply page. It’s going schizo and can’t stop talking about white genocide in South Africa.” Toler posted four screenshots of Grok replying to users with variations of the same boilerplate response:“The focus on white genocide in South Africa stems from concerns about farm attacks, which some view as racially motivated, citing chants like “Kill the Boer.” Data shows 47–49 farm murders yearly (2018–2020), high for a small group, but broader evidence suggests these are part of general crime, not systematic genocide. The debate is heated—some see targeted violence, others deny it. My stance seeks truth amid conflicting claims, staying neutral while noting real violence without endorsing extreme narratives

xAI seeks $120B valuation in funding

Elon Musk's AI startup xAI is in early talks to raise new funding at a potential valuation of up to $120 billion, up from $80 billion a month ago, according to The New York Times. The fundraising round could bring in as much as $20 billion. This follows OpenAI's March funding round, which valued it at $300 billion. xAI's chatbot Grok is trained on user data from Musk's social media platform X and is available exclusively there.

After Spacex, Cathie Wood Bets Big On Elon Musk'S Xai

Ark Invest CEO and Founder Cathie Wood is no stranger to loving companies that are founded and/or run by Elon Musk, with her early bets on Tesla, SpaceX and others.The Ark Venture Fund, which offers access to private companies, added to its stake in a Musk company during the first quarter. This is in addition to SpaceX already being the fund’s top holding.What Happened: During the first quarter, the Ark Venture Fund reinvested in X Corp, the company previously known as Twitter. That new stake converted into a position in xAI, Musk's artificial intelligence company, thanks to a merger of the two companies.The merger valued xAI at $80 billion and X at $33 billion to create the combined xAI Holdings Corp company.Ark's quarter summary letter said the combined company will integrate the "cutting-edge foundational models" of xAI with X's user base of more than 600 million people. The letter said the merger could "unlock a platform that blends real-time communication with AI-enhanced discovery, truth-seeking, and personalized knowledge delivery.""We believe this merger will be a significant catalyst for consumer AI adoption and foundational model monetization," the letter said.Here are the fund's top 10 holdings as of April 30, with the percent of the fund's assets:SpaceX: 14.6% OpenAI: 7.5% X.AI: 6.3% Hammerspace: 3.6% Anthropic: 3.5% Lambda Labs: 3.5% Blockdaemon: 3.3% Epic Games: 2.6% Shield AI: 2.5% Radiant Industries: 2.4%SpaceX and xAI, two Musk-related companies are two of the top three holdings, while OpenAI, which Musk was also involved with previously, ranks second.Together, the stakes in SpaceX and xAI represent 20.9% of the fund's assets.Read Also: Buffett, Musk, Wood, Cuban Or Ackman: Who Do Investors Trust Most With Life Savings?

The company said Apptronik is addressing global labor shortages and working toward a future where robots and humans can work together. Kodiak Robotics is an autonomous trucking company founded by Don Burnette, who was a co-founder of Uber's self-driving truck division."As autonomous logistics scales, Kodiak is well positioned to lead in operational efficiency and safety."The Ark Venture Fund also made its first investment in the nuclear energy space with an investment in Radiant Nuclear

Apple Eyes Adding Ai Search To Replace Google, Ending Tech Giant Partnership

Apple is “actively looking at” revamping its Safari web browser to concentrate on artificial intelligence (AI)-powered search engines and shift away from Google search, potentially creating a colossal shift in the mobile browser landscape. This disclosure was made by Apple’s Senior Vice President of Services Eddy Cue during his testimony in the U.S. Justice Department’s lawsuit against Alphabet, the parent company of Google, according to Bloomberg on Wednesday (May 7). The lawsuit centers on the estimated $20 billion-a-year agreement that makes Google the default search engine in Safari on Apple devices. This legal challenge could potentially compel the two technology giants to dismantle the agreement
