Tesla stock falls as the Trump-Musk feud is heating up again

Once close allies, the two billionaires are back on their respective social media platforms dragging each other down.

The billionaires are fighting on their respective social media platforms again, sending Tesla stock down 7% premarket.

Tesla CEO Elon Musk and President Donald Trump rekindled their on-again, off-again online feud over the holiday weekend, when Musk claimed to have launched his threatened third political party, the “America Party.”

By a factor of 2 to 1, you want a new political party and you shall have it!

When it comes to bankrupting our country with waste & graft, we live in a one-party system, not a democracy.

Today, the America Party is formed to give you back your freedom. https://t.co/9K8AD04QQN

In response, Trump took to Truth Social to call Musk a “TRAIN WRECK” and say his political party would cause “DISRUPTION & CHAOS.”

Now Musk is back on X making fun of the president and once again making veiled accusations of Epstein connections — in a feud that could have negative consequences for Musk’s companies, especially Tesla’s self-driving aspirations. As analyst Dan Ives wrote yesterday, “Trump can create more hurdles for Musk/Tesla/SpaceX over the coming years if this political battle gets nastier heading into mid-terms in 2026.”

This latest feud seems to be reaching a boiling point after it started again last week. After Musk criticized Trump’s tax bill, which has since become law, the president said he was going to have DOGE, the organization Musk formerly led, “take a good, hard, look” at the subsidies Musk’s companies get, and would consider deporting him. The spat seemed to cool, only to reignite this weekend when Musk said he had formed a competing political party.

The two had their first public blowout in early June, which started with criticism of the “big, beautiful bill” and ended with veiled accusations of pedophilia. Tesla stock plummeted and then recovered.

Tesla, of course, has other things weighing on it as well, including mounting problems in China, its second-biggest market; falling vehicle sales globally; and big questions about the safety of its self-driving technology.

Currently the stock is down 11% from where it closed June 4, the day before the beef first exploded.

Prediction markets have, predictably, been given a boost by the summer of sports

Major platforms like Kalshi and Polymarket have seen huge upticks in users of late, thanks in no small part to what’s felt like a recent sporting smorgasbord, with major competitions across hockey, basketball, and soccer soaking up fans’ time (and spending, clearly) at the outset of summer.

While gaming industry groups may not like it, there’s been a huge change in the methods people are using to put money on the big games, with everyone from fortunate NYC bar owners, to a far less fortunate Spanish supporter, turning to prediction markets to try and turn their sports know-how into cold, hard cash.

According to a new report from Adam Blacker for apptopia, that shift might have been even more seismic than imagined in the wake of the NBA and NHL finals and around the 2026 World Cup kicking off.

Anthropic pulls Fable and Mythos access worldwide after Trump administration bars their use by foreign nationals

Only days after releasing two versions of its next-gen AI model, Anthropic has disabled them for users worldwide.

Anthropic says it received a Friday night order from the Trump administration to suspend access to the models for any foreign national (anywhere in the world) — a group that included some Anthropic employees. In response, the company turned off access to everyone.

Last week, the company released to the public its much-anticipated Claude Fable 5 model (and its restricted version Claude Mythos 5, which is still being tested with trusted partners). Anthropic said in a blog post announcing the action that officials cited national security concerns with the new models, while offering few specific details.

The post said that the government gave the company “verbal evidence of a potential narrow, non-universal jailbreak” of the public Fable 5 model. A jailbreak is a means by which users can evade restrictions built into the code to unlock prohibited functionality. Anthropic downplayed the significance of the attack, and said other major models, such as OpenAI’s GPT-5.5, could also be affected by the technique described.

Fears of these first Mythos-class models being misused are running high, after Anthropic warned the cybersecurity world in May that the advanced cyber capabilities of Mythos have rapidly discovered thousands of vulnerabilities in ubiquitous software, leading to the decision to restrict the full version of the model to a close group of trusted partners for testing.

This morning, Axios reported that Anthropic technical staff have flown to Washington to meet with White House officials to resolve the issue.

The Wall Street Journal is reporting that the Trump administration’s decision to take action against Anthropic was prompted by discussions that Amazon CEO Andy Jassy had with officials, including Treasury Secretary Scott Bessent. According to the report, Amazon researchers said they had been able to evade some of Fable 5’s security restrictions using specific prompts. Amazon is a major investor in Anthropic.

Anthropic is currently suing the US government to fight the Pentagon’s blacklisting of the company on national security grounds.
