It began in Seoul. On Tuesday, July 29, 2026, Samsung Electronics closed down 13.4%, SK Hynix fell 14.7%, and Tokyo Electron lost 11% — single-day drops that would, within 72 hours, cascade through global markets, drag Bitcoin to a two-month low of $62,785, and wipe approximately $2 trillion from South Korea’s benchmark KOSPI index alone AFR: “Get out of this hell”.

This was not a routine correction. It was the violent unwinding of a leveraged mania that had been building for 18 months — a mania fueled by AI euphoria, single-stock ETFs, and tens of millions of retail investors who had bet everything on the semiconductor boom.

And it spilled directly into crypto.

The Korean Semiconductor Bubble: A Cautionary Tale

South Korea’s KOSPI had been one of the world’s best-performing stock markets in 2025 and early 2026. At its June peak, the index had surged nearly 75% from the prior year, driven almost entirely by two stocks: Samsung Electronics and SK Hynix, which together account for nearly half of the KOSPI’s total weighting My life’s screwed’: Korean investors stress out after AI bubble bursts.

The thesis was simple but powerful. Samsung and SK Hynix manufacture the high-bandwidth memory (HBM) chips that power Nvidia’s AI data centers. As the AI buildout accelerated, demand for HBM exploded. SK Hynix, in particular, became a proxy for the entire AI trade — at one point up roughly 180% year-to-date at its peak Get out of this hell’: Investors panic after chip bubble bursts.

But the foundation was shakier than it appeared.

The Leveraged ETF Time Bomb

In late May 2026, South Korean regulators approved 16 single-stock leveraged ETFs tracking Samsung and SK Hynix AI Stock Rout Spills Into Crypto as Bitcoin Slides and Liquidations…. These products — offering 2x daily exposure to individual stocks — were adopted with almost religious fervor by retail investors who had missed the 2025 rally and were desperate to catch up.

The numbers tell the story:

“The unwinding of leveraged ETFs tracking the volatile semiconductor sector is sending shockwaves through the market, with many retail investors seeing their principal nearly wiped out,” said Namuh Rhee, chair of the Korean Corporate Governance Forum My life’s screwed’: Korean investors stress out after AI bubble bursts.

The Trigger: Chinese Competition and Financing Fears

What punctured the bubble was a convergence of three concerns:

  1. Chinese competition. Reports emerged that Chinese firms were developing domestic deep ultraviolet (DUV) lithography gear, threatening Samsung and SK Hynix’s competitive moat. The strong market debut of Chinese memory maker CXMT added to the pressure Did DeepSeek Crash The Crypto Market? Nearly $1 Billion in Liquidat….

  2. AI buildout financing sustainability. Analysts and wire reports flagged questions about how the Nvidia/OpenAI data-center buildout would be financed, raising doubts about the sustainability of demand growth Did DeepSeek Crash The Crypto Market? Nearly $1 Billion in Liquidat….

  3. Global contagion. The PHLX Semiconductor Index fell 4.5% on Tuesday, now sitting 22.5% below its one-month high. The selling was not Korea-specific — it was a global repricing of AI-exposed equities Did DeepSeek Crash The Crypto Market? Nearly $1 Billion in Liquidat….

Human Toll

The human impact is staggering. Song Mi-kyung, a 60-year-old Seoul resident who had pocketed roughly $200,000 in early 2026 gains, saw her portfolio drop by more than 60% in a matter of days Financial Post.

“The losses are ballooning day by day. I am really stressed out. I don’t know what to do about it,” she told the Financial Times. “I’ve never seen such rapid falls, not even during the Asian financial crisis. I’m about to give back all the gains I’ve made this year” My life’s screwed’: Korean investors stress out after AI bubble bursts.

Brokerage Korea Investment & Securities reported that nearly 70% of its 408,000 investors in SK Hynix were sitting on losses, while nearly half of its 880,000 Samsung investors were also in the red My life’s screwed’: Korean investors stress out after AI bubble bursts.

The Crypto Spillover

The contagion did not stop at the KOSPI.

Bitcoin’s Plunge

Bitcoin (BTC) fell to a 24-hour low of $62,785 — its weakest level in roughly two months and a 4.3% drop from Monday’s intraday high of $65,618. It recovered modestly to around $63,836 by Wednesday afternoon AEST, but remained down 3.7% over seven days Did DeepSeek Crash The Crypto Market? Nearly $1 Billion in Liquidat….

The move confirmed a pattern that has been building throughout 2026: crypto and AI-exposed equities are increasingly correlated. As the two sectors converge — through shared investor bases, overlapping narratives, and mutual dependence on compute infrastructure — shocks in one increasingly transmit to the other.

A $500M+ Liquidation Cascade

According to liquidation trackers, forced closures exceeded $500 million over 24 hours, with individual tallies running as high as $682 million. One tracker broke it down as $543 million in long liquidations against just $72 million in shorts — meaning nearly 90% of the pain was on the long side Did DeepSeek Crash The Crypto Market? Nearly $1 Billion in Liquidat….

This is consistent with the pattern seen in Korea: leveraged bulls, not bears, were caught offside.

Altcoins and AI Tokens

The broader crypto market felt the pressure:

AI-related tokens — which had already been hit in January 2025 by the DeepSeek shock — faced renewed headwinds. The SoSoValue AI token index had seen an 11% single-day decline during the DeepSeek rout back in January [CryptoMode — Did DeepSeek Crash The Crypto Market? Nearly $1 Bill…. While AI tokens were not the primary driver this time, the structural correlation between AI equities and crypto means every semiconductor sell-off carries implications for the AI-crypto token sector.

Structural Implications: What This Means Going Forward

1. The AI-Crypto Correlation Is Real and Growing

The January 2025 DeepSeek event showed that a breakthrough in AI efficiency could crash bo — and by extension, AI-related crypto tokens — could shift lower.

4. Diversification Matters More Than Ever

If AI and crypto are becoming the same trade, then holding both is not diversification. The events of July 29–30, 2026, argue for a thoughtful separation between AI-equity exposure and crypto exposure — or at minimum, an awareness that they may crash together.

What to Watch Next

  • KOSPI recovery trajectory. Analysts expect the recovery to be slow, with extreme volatility discouraging institutions from taking large positions while retail investors remain traumatized My life’s screwed’: Korean investors stress out after AI bubble bursts.
  • Crypto liquidations. If forced selling in Korean equities continues, further crypto liquidations are possible as leveraged traders in both markets are forced to deleverage simultaneously.
  • AI token resilience. The AI token market cap now sits at roughly $24B–$27B sector-wide CryptoNews Australia. The question is whether that valuation can decouple from AI equities in a downturn, or whether it will track them lower.
  • Regulatory response. The role of South Korea’s regulators in approving the single-stock leveraged ETFs is already drawing scrutiny AI Stock Rout Spills Into Crypto as Bitcoin Slides and Liquidations…. A similar debate is brewing in the U.S. around crypto leverage products.

The Bottom Line

The AI stock rout of July 2026 was not a flash crash or a technical glitch — it was the unwinding of a leveraged bubble that had been inflating for a year and a half. Tens of millions of retail investors in South Korea were caught holding the bag when the semiconductor trade turned. Crypto markets, increasingly correlated with AI equities through shared investor bases and overlapping narratives, took the hit alongside them.

Bitcoin at $62,785 is not a disaster. But the mechanism by which we got there — a Korean semiconductor panic that cascaded into a global risk-asset sell-off — is a structural feature of the post-convergence market, not a bug. And it will happen again, in a different form, until the AI-crypto correlation is better understood and priced in.
