Here's your afternoon TNB Tech minute for Friday, December 5th. I'm Julie Cheng for the Wall Street Journal. We exclusively report that SpaceX is kicking off a secondary share sale that would value the rocket maker at $800 billion. That's according to people familiar with the matter. This would make it the most valuable US private company, surpassing OpenAI, sources say SpaceX's CFO told investors about the sale in recent days. A recent secondary share sale fetched the company a valuation of just half that at $400 billion. SpaceX didn't immediately respond to a request for comment. Moving on to another Elon Musk company. Social media platform X has been hit with a roughly $140 million fine in the European Union over alleged breaches of the block's landmark digital content law. The fine marks the first ever penalty the EU has handed out under the Digital Services act after a years long probe. The European Commission alleged X's Blue checkmark system deceives users and falls foul of the rules. It also said the platform's advertising transparency and data access rules were in breach of the law. Moreover, the commission is still scrutinizing X over the possible spread of illegal content. X didn't immediately respond to a request for comment. The commission said the company now has 60 days to propose a solution for its Blue check system and 90 days to address ad transparency policies and shares of Chinese AI chipmaker More Threads soared 425% in its market debut today after raising more than $1 billion in an IPO. More Threads was founded by a former Nvidia executive and is looking to essentially become China's version of Nvidia. More Threads designs chips known as graphics processing units or GPUs for AI training. We revenue more than tripled last year, but the company remained loss making. Beijing has been pushing to develop a domestic AI ecosystem that doesn't rely on foreign technology or computing power. And that's a wrap on your TMB Tech Minutes check back Monday morning for another quick tech update.
