He either was trolling in which case he was stupid to not realize you can only go so far with that, or he genuinely offered to buy it, but then realized he had overpaid, which if so showed a lack of financial and investment sophistication of his part, which wouldn't be surprising. He had to take on a lot of personal debt to buy it.Meta and Alphabet are both near their all time highs while Twitter/X/DumpsterFire almost certainly is not, by any measure. While profit and valuation issues for Twitter were widely predicted I don't think the real-time trainwreck that is happening right now was what folks were thinking of when they made those forecasts before Musk bought it in 2022.
The irony behind his purchase is it is likely the result of him just trolling Twitter, possibly because they refused to ban the 'Elon Jet Tracker' account on the network. Unfortunately for him some contracts are indeed enforceable and a judge made him follow through on his purchase.
What I find amazing is how he seems to be intent on destroying his investment.
