SK Hynix Shares Jump 14% on Nasdaq Debut, UK Foreign Ownership Hits 35% Post-COVID High

SK Hynix Hits Nasdaq, Shares Surge 14%

SK Hynix made its U.S. market debut today, July 10, 2026, and shares jumped 14% in early trading on the Nasdaq, according to Reuters and Bloomberg. The debut marked one of the more watched IPO moments of this year.

The South Korean chipmaker raised $26.5 billion in what Bloomberg called a "mega US share sale" — a figure that cleared yesterday. The company is a dominant player in high-bandwidth memory (HBM) chips, the hardware increasingly powering AI infrastructure buildouts. Demand for HBM has been relentless, and SK Hynix competes directly with Samsung and Micron for contracts with companies like Nvidia.

The Nasdaq jump signals that institutional buyers see real runway here, not just momentum trading. Reuters framed the debut as evidence that "AI euphoria persists," a reading supported by relentless HBM demand.

The strongest case for caution: AI-driven chip stocks have been volatile, and enthusiasm around a debut often fades once lockup periods expire and early investors look for exits. A 14% first-day pop says nothing about where the stock trades six months from now. Anyone treating today's price as a valuation floor is making a bet, not reading a balance sheet.

The broader market context is mixed. According to Bloomberg, U.S. stock futures slipped this morning after a strong week for tech, and the S&P 500 and Nasdaq were wavering as of midday, even as SK Hynix's debut drew attention. The Wall Street Journal noted that "tech stock jitters" have risen, even as earnings expectations keep money flowing in. U.S. equity funds drew their biggest weekly inflow in three weeks, according to Reuters, driven by hopes around Q2 earnings.

Bank earnings are the next test. Bloomberg noted Wall Street is bracing for Q2 results, with banks taking center stage in the coming days.

Foreign Ownership of UK Companies Up 35% Since COVID

While chip stocks grabbed headlines, a separate data story has been developing over the past several years with little attention in U.S. financial press.

The UK's Office for National Statistics reported that just over 200,000 UK businesses were under foreign control in 2024, up from 148,742 in 2020. That's a 35% increase in four years, even as the total number of businesses in the UK stayed roughly flat, according to Bloomberg and Business Insider Africa.

The drivers are not mysterious. Britain offers lower company valuations relative to U.S. and continental European peers, a weaker pound that makes acquisitions cheaper in dollar or euro terms, and access to global capital markets. Foreign buyers have been rational actors responding to price signals.

North American, European, and Asian investors account for the bulk of that growth. A notable subplot is South African corporate expansion into Britain.

Industrial conglomerate Bidvest Group built its UK presence not through a single large deal but through a sustained series of acquisitions across foodservice, facilities management, commercial products, and industrial services. The UK has become one of Bidvest's largest international markets outside South Africa.

Investec, founded in Johannesburg, significantly expanded its UK investment banking presence with its 2011 acquisition of Evolution Group, making London one of its two principal operating markets. Today Investec runs substantial banking, wealth management, and advisory operations out of the UK.

Old Mutual similarly established a London base over several decades before restructuring parts of its international business, according to Business Insider Africa.

A fair concern from a British sovereignty standpoint: a 35% jump in foreign-controlled businesses in four years, with the total business count flat, means a materially larger share of UK economic activity now answers to foreign boardrooms. That is not inherently bad. Foreign investment creates jobs and sustains businesses that might otherwise fail. It does concentrate strategic decisions outside UK jurisdiction. Critics who raise that point are describing a structural shift with real governance implications.

The rebuttal is also real: the UK is a voluntary, transparent market. These companies did not seize assets; they bought them at prices British owners agreed to. A weaker pound and lower valuations are a policy consequence, not a corporate conspiracy. If UK policymakers want to retain domestic ownership of strategically important sectors, that conversation starts in Parliament, not in the M&A press release.

What Connects These Stories

Both data points reflect the same underlying force: capital chasing AI and undervalued assets simultaneously. SK Hynix's Nasdaq debut attracted dollars because AI infrastructure demand is real and growing. UK acquisition activity has accelerated because valuations are relatively cheap and cross-border capital flows have no shortage of willing buyers.

SK Hynix's $26.5 billion raise is one of the largest share sales of the year. Whether the Nasdaq listing gives it a durable valuation premium over its Seoul-listed shares, and whether that premium holds once the debut euphoria clears, will become clearer when Q2 earnings from major AI infrastructure companies land over the next several weeks.
