It didn't collapse in the sense of ceasing to exist. It did collapse as a place where decent human beings cared to gather, and it lost over 75% of its market value.
No longer true. In March 2025, X Corp. was acquired by xAI, Musk's artificial intelligence company. The deal, an all-stock transaction, valued X at $33 billion, with a full valuation of $45 billion when factoring in $12 billion in debt.
Investor sentiment through secondary share trades still prices the company at $44 billion.
To be fair, the banks did offload the debt at par (two years later) so some people think X/Twitter is worth some money.
