SK Hynix Plows $67 Billion Into Chip Capacity as ADR Debut Looms, But Broadcom's Shadow Triggers 12% Rout

SK Hynix shares fell 12.3% after Broadcom's AI revenue miss, but strong HBM4 position for Nvidia's Vera Rubin, $67B capex plan, and upcoming US ADR listing underscore its long-term growth.

The trigger came from an unlikely place. Broadcom, the diversified chip giant, set AI chip revenue expectations for the coming quarter at $16 billion — roughly $1.2 billion short of consensus. That single miss sent shockwaves through the semiconductor complex, wiping out over a tenth of the Philadelphia Semiconductor Index in its worst single-day slide since March 2020.

SK Hynix, despite being a direct beneficiary of the AI boom, was caught in the crossfire. Shares tumbled 12.29 percent on Friday to close at 2,070,000 Korean won, trimming the seven-day loss to 11.27 percent. An unexpectedly strong US jobs report added fuel to the fire, sending bond yields higher and hammering growth-dependent tech stocks whose valuations hinge on distant future earnings.

Yet even as this unfolded, SK Hynix’s operational picture was strengthening. Nvidia CEO Jensen Huang confirmed on June 5 that all three major memory makers — SK Hynix, Samsung, and Micron — are qualified to supply HBM4 for the upcoming Vera Rubin platform. “All three are qualified. All three are in production, and all are running to support Vera Rubin,” he said. While Nvidia hasn’t disclosed volume allocations, supply chain estimates peg SK Hynix as the dominant supplier with 60 to 70 percent of HBM4 shipments for Vera Rubin, followed by Samsung at 25 to 30 percent and Micron taking the remainder. Shipments of the new platform are slated to begin in the third quarter of 2026.

The company is simultaneously making a massive bet on future demand. Speaking at Computex in Taipei, SK Hynix CEO Chey Tae-won outlined plans to double monthly wafer production from roughly 550,000 to 1 million units, with a capital expenditure roadmap of $67 billion between 2024 and 2028. Capacity additions stretch to 2031, including a new fab in the Yongin cluster due to begin installation in February 2027 and the M15X plant in Cheongju, which will start at 40,000 wafers in the second half of 2026 and ramp to 80,000 by 2027. Capital spending this year will significantly exceed last year’s 30.2 trillion won. To help finance the buildout, SK Hynix plans to issue American depositary receipts in the US during the second half of 2026, potentially raising up to $14 billion. The SEC is reviewing the plan; exact size and timing remain unconfirmed. The move, which also aims to broaden the shareholder base among large US funds, comes after the company briefly crossed a $1 trillion market capitalization in late May. A weaker Korean won has added further urgency to the ADR listing.

On the product roadmap, the competition is already heating up. SK Hynix intends to deliver first samples of the next-generation HBM4E memory in the second half of 2026, with mass production targeted for 2027. Rival Samsung has already shipped 12-layer HBM4E samples to key customers, boasting speeds of up to 16 Gbit/s and bandwidth of 3.6 TB/s per stack — more than 20 percent above the previous HBM4 generation. Sampling, however, is not qualification, and volume orders remain distant. According to Counterpoint, SK Hynix held 58 percent of the global HBM market at the start of the year, with Samsung and Micron each at 21 percent.

Analysts remain divided on the near-term outlook. Meritz Securities views the latest drop as profit-taking following an extraordinary rally, noting that fresh catalysts are scarce until the July earnings report. Kim Young-gun at Mirae Asset Securities, on the other hand, sees memory chip demand outstripping supply through 2028 and has raised price targets for both SK Hynix and Samsung, arguing that the long-term AI thesis remains intact even if short-term valuation pressure persists.

Despite Friday’s bloodbath, SK Hynix shares are still up 205.76 percent year-to-date, trading 42.06 percent above their 50-day moving average and only 14.00 percent below the recent 52-week high. For now, the market narrative pits a confident, investing company against a jittery sector that punishes even minor disappointments. Whether the selloff proves a buying opportunity or a warning sign will likely depend on whether the broader AI trade stabilizes before the next quarterly numbers arrive in July.
