OpenAI is valued at 90 billion and all they do is make GPT; Twitter is valued at 40 billion and this was essentially a vanity side-project by a cowboy CEO. Presuming that benchmarks and general “it’s about the level of 3.5” is accurate, it’s inefficient, but not incredibly inefficient imho
They weren't even 44B when elon took the keys - he specifically tried to back out of the deal because 44B was insane peak '21 asset bubble price. In truth they were probably like 10-15B at that moment. And now that bunch of advertisers left due to we know who it's probably about 10B
twitter was valued around 30 billion when musk tried getting out of buying it (then the market cap went up when it became clear that he would be forced to pay full price)
