Elon Musk posts addresses online in attempt to display Grok capabilities

SpaceX CEO Elon Musk, seen in 2025, recently showcased Grok, SpaceXSI's artificial intelligence chatbot, finding online deals and completing purchases.

Billionaire Elon Musk has long claimed his wealth isn’t sitting in a bank account. After the Telsa CEO shared private purchase details online, that might be in his best interest.

Over the weekend, Musk noted that Grok — the artificial intelligence chatbot developed by SpaceXSI, formerly SpaceXAI — can find internet deals and complete purchases. To demonstrate, he posted a screenshot of the bot's response to his request for Lego Star Wars sets.

However, in the screenshot of the $241 purchase Musk posted on X, he neglected to edit or blot out the shipping and billing addresses, tied to locations in Austin and Lakeway. The post also featured details about his payment method, the email address tied to the order, the order number and more.

For security, users should always avoid sharing sensitive data on social media. But Musk, who bought Twitter in 2022, doesn’t seem to be sweating the risk. The posts are still active days later, though he wrote in a follow-up post that the addresses are where he receives mail, not where he lives.

One user claimed to have canceled the order, while another claimed to have increased the order quantity to 400 and changed the delivery address.

Even before posting the screenshot, Musk potentially put himself at risk by tapping into the increasingly popular of having AI shop for him. OpenAI, Meta and others have also touted the ability of its bots to perform so-called “agentic commerce”

Last year, Visa warned that fraudsters are using new tactics to adapt to AI-driven transactions. As shopping agents work to find the best deals and make purchases on behalf of consumsers, the bots can be deceived by counterfeit merchants that appear legitimate, pass automated security checks and offer prices far below market rate. But once the purchase is completed, the fake merchant can harvest payment data and use it for unauthorized transactions.

Visa noted that it had seen a 25% increase in malicious bot-initiated transactions over the past 6 months, with the U.S. experiencing a 40% increase.

American Express, which Musk used for his Lego purchase, says it has made an industry-first move to launch agent purchase protection to safeguard card members and merchants from charges related to errors by registered AI agents.

Still, the company warns merchants not to lower their defenses.

“Trust is going to be the key,” says Stefan Olofsson, senior vice president and general manager of Amex Global Network & Products. “If you don't know who the agent is, who the customer behind it is, or where the transaction request came from, you have no visibility.”
