Bitcoin is moving in the opposite direction of South Korea’s equity market, a divergence that underscores shifting investor sentiment around artificial intelligence and technology spending. As first reported by CoinDesk, the divergence has become stark: while Seoul’s KOSPI index plummeted 5.5% on Tuesday and now sits 38% below its June peak, bitcoin has surged 40% from its recent low of $58,000 to highs near $87,000.
The two assets are now showing a moderately negative 20-week rolling correlation of -0.41, suggesting they are moving in opposite directions. This is no coincidence. Mounting doubts about whether the AI sector can justify its infrastructure costs have hammered chip stocks globally, yet bitcoin appears to be benefiting as capital rotates away from speculative tech trades.
Broadcom’s Reality Check Sparks Chip Rout
The pressure intensified Tuesday after Broadcom CEO Hock Tan compared speculative AI investing to gambling in a casino. His comments, reported by the Financial Times, cut to the heart of an investor concern that has been building for months: whether the enormous spending on AI chips and infrastructure can generate sufficient returns.
That skepticism hit semiconductor makers hard. South Korea’s two giants — SK Hynix and Samsung Electronics — fell around 10% and 7% respectively. The selloff has spread globally, with U.S. memory and storage chipmakers Micron Technology and SanDisk both down around 3% in premarket trading.
Chinese memory-chip manufacturer CXMT’s claimed breakthrough has added fuel to the fire, raising competitive concerns and threatening to compress margins at established players. For investors already questioning whether AI spending will pay off, the prospect of new competition on price was the final straw.
Bitcoin’s Counter-Narrative
Bitcoin’s recovery suggests a different calculus among some investors. The cryptocurrency bottomed near $58,000 shortly after the KOSPI peaked in June. Since then, as equities have deteriorated, bitcoin has staged a 40% rebound.
The negative correlation between bitcoin and the KOSPI does not prove capital is flowing directly from South Korean stocks into cryptocurrency. Correlation alone cannot establish causation or capital rotation patterns. But the divergence is meaningful: while traditional tech investors are reassessing valuations, bitcoin holders may be viewing the asset as uncorrelated to AI trade enthusiasm or disappointment.
This shift highlights how bitcoin continues to occupy its own niche in global markets — less tethered to fundamental earnings narratives than equities, more sensitive to macro conditions and sentiment around risk appetite broadly.
