According to StockMKTNewz, Nippon Steel has finalized its $14.1 billion acquisition of US Steel, marking the end of US Steel's independent listing under the $X ticker (source: StockMKTNewz, June 18, 2025). This high-profile M&A deal underscores growing global consolidation in traditional industries, prompting traders to watch for capital flows out of legacy equities and into alternative assets such as Bitcoin (BTC) and Ethereum (ETH). The closure may also impact tokenized equity products and synthetic stocks on crypto exchanges, as $X ceases to exist as a listed security.
