Today's dark line
The escalation of U.S.-Iran tensions coinciding with a rebound in the chip market is no coincidence—geopolitical risks are pushing up oil prices and inflation expectations, forcing markets to reallocate toward "hard tech" as a hedge. SK Hynix’s IPO being oversubscribed, European semiconductor stocks rebounding, and NVIDIA being viewed as a "value洼地" all point to the same logic: when traditional safe-haven assets like gold and bonds fail under inflation, companies capable of producing actual computing power become the new safety net. Meanwhile, OpenAI, xAI, and Anthropic have simultaneously released new models; the AI arms race is not slowing down amid macroeconomic uncertainty—it’s accelerating, because whether it’s war, energy crises, or economic recession, computing power remains the only reliably growing production factor.
