I am unable to find any information confirming that SK Hynix raised $26.5 billion in a U.S. market debut as of the specified date. Web searches for "SK Hynix U.S. market debut" or "SK Hynix IPO" do not yield results matching this headline or figure. SK Hynix is a well-established South Korean company, and there is no record of a recent U.S. market debut or a capital raise of this magnitude for the company as an IPO or secondary offering.
The provided URL, https://www.ft.com/content/33133a86-925e-4395-9f60-35e2a4052500, does not lead to an article about SK Hynix. Instead, it appears to be a broken or non-existent link for the Financial Times. Without a valid source or confirming news, I cannot provide a detailed summary of this purported event.
Therefore, based on current information, the assertion that SK Hynix raised $26.5 billion in a U.S. market debut cannot be substantiated, and this event likely did not occur.
