Musk has started shifting value among his companies to "optimize" his finances. The first move was to merge X with XAI. I bet his loans with Morgan Stanley got restructured as part of the $10 billion XAI round Morgan Stanley led. Which also explains why Morgan Stanley didn't squawk when the round was announced the same week that Grok decided to call itself Mecha Hitler and go on an alarming rant about people with certain surnames.
Now he's putting Grok in Tesla cars, creating licensing and other revenue streams from a publicly traded company to XAI, where he owns a much higher percentage of the shares.
