The fear of missing out often leads investors to jump on the next big investment trend, but history shows that this approach is not sustainable over the long run. The rise of artificial intelligence (AI) has been hailed as the next big thing, with analysts predicting a massive boost to the global economy. Nvidia, a leading player in AI technology, has seen its stock soar over the last 18 months, with the company becoming the world's largest publicly traded company. However, while short-term catalysts have driven this explosive growth, mounting long-term headwinds suggest that Nvidia may be in an irrational bubble. Competition from other tech giants and the maturation process of next-big-thing trends indicate that Nvidia's trillion-dollar market cap may not be sustainable in the long term. As history has shown, FOMO-driven investment trends often lead to bubble-bursting events, and Nvidia may struggle to remain a trillion-dollar company by 2026.
