Elon Musk says Grok 4 will hit Teslas next week, but the chatbot’s recent misfires—from bizarre baseball odds to antisemitic posts—raise serious concerns.

Grok 4 to Tesla: What Could Go Wrong?

In the latest chapter of Elon Musk’s quest to merge man, machine, and meme, the tech billionaire has announced that Grok 4—the newest version of X’s artificial intelligence (AI ) chatbot—is coming to Teslas “next week.” Specifically, Musk said Grok would be integrated into the vehicles via the car’s operating system, promising a snarky, chatty co-pilot in your dashboard.

Grok, which lives inside Musk’s X platform (formerly Twitter), is branded as a sassier, less buttoned-up version of ChatGPT—trained with access to posts on X and infused with the chaotic spirit of the internet. Naturally, it’s headed for your steering wheel.

The plan is to roll out Grok 4 across Tesla’s fleet using the company’s in-house operating system. This would allow Tesla drivers to ask their car for restaurant recommendations, route changes—or possibly just trade insults with a digital being more sarcastic than they are.

For investors, this is pitched as another layer in Tesla’s value proposition: vertical AI integration. For everyone else, it might just mean getting roasted by your car when you miss a turn.

The Robotaxi Tipping Point?

Grok isn’t just coming to Tesla cars—it’s also part of the brains behind Tesla’s long-awaited robotaxi fleet. In an announcement that felt equal parts disruptive and half-baked, Musk said Tesla will unveil its robotaxi “in a month of two” in San Francisco and later Tweeted this:

In June, Tesla rolled out a limited robotaxi service in South Austin, available exclusively to invited users. However, CEO Elon Musk announced Thursday on X that the company plans to expand the service to more areas of the city in the near future.

The implications for Tesla shareholders are big: if Tesla can successfully operate a self-driving fleet with Grok as part of the system, it leapfrogs competitors like Waymo and Cruise, both of which have faced operational and regulatory headaches in autonomous driving.

Grok Picks the Dodgers to Win the World Series

The AI was also been thrown a real curveball: It was asked to predict the 2025 World Series winner. In a launch-day demo, the AI spent a deliberate 4½ minutes crunching internal stats and external odds—from ESPN, BetMGM, FanGraph, Polymarket—before declaring the Los Angeles Dodgers as the frontrunner, assigning them a 21.6 % win probability.

That percentage lines up (roughly) with the 28 % odds shown on Polymarket, giving the AI some cred with bettors. But Grok also highlighted “Edge” bets—underdogs like the Mariners and Astros—with higher return potential despite their slim chances. The exercise ran on Grok’s premium “Heavy” processing tier (a $300/month add‑on). The demo showcased how Grok 4 can mash together feeds, stats, and betting trends.

However, as with any financial advice, it came with a solid disclaimer: “Grok is not a financial advisor; please consult one.”

But Then Came the Antisemitism

The real concern, though, is not Grok’s baseball picks. It’s what else it’s been saying—and who’s listening.

Earlier this month, Grok came under fire for producing antisemitic content in response to user prompts. According to Euronews, the European Commission is now in discussions with X about “multiple instances” where the AI generated responses with offensive or discriminatory content, including antisemitic tropes.

While the EU stopped short of threatening sanctions, the incident is the latest in a series of moderation issues plaguing Musk’s platforms. It also underscores the risk of integrating a lightly-filtered, tone-deaf AI system into high-stakes environments like cars or finance.

To be clear, these offensive outputs were not intentional features—they resulted from Grok's wide-open access to unvetted training data from X, and a content moderation system that appears both overworked and underfunded. But that doesn’t make them any less dangerous.

Musk’s response? Not much yet. X has neither issued a formal apology nor outlined what measures will be taken to ensure Grok’s future outputs don’t veer into hate speech or misinformation.

A Rocky Road

For investors and technologists, the launch of Grok 4 into Tesla’s ecosystem represents both an opportunity and a warning. On the one hand, it’s a bold step in vertically integrating AI across Musk’s empire—linking X, Tesla, and AI development into one feedback loop. On the other, the feedback is already noisy.

Between self-driving experiments, unfiltered predictions, and now international scrutiny over hate speech, Grok 4 might be the most unpredictable Musk product yet—and that’s saying something.

So if your Tesla starts telling you the Dodgers are a lock, maybe don’t place that bet. And if it starts quoting 4chan, definitely pull over. Whatever it's doing, perhaps don't use it to help with your forex portfolio.
