Renowned economist Nouriel Roubini, often dubbed ‘Dr. Doom,’ has revised his outlook on the U.S. economy, moving away from a recession prediction to one of optimism. He predicts that technological breakthroughs, such as artificial intelligence and nuclear fusion energy, will fuel investment and productivity growth in the United States by 2030. Roubini anticipates a GDP increase from the current 2% to 4%, and expects the U.S. stock market, including indices like the S&P 500, to experience substantial gains of single-digit percentages by 2025. Roubini attributes his optimistic forecast to the accelerated adoption of AI advancements and the imminent commercialization of nuclear fusion energy, combined with a more responsive market driven by policies from former President Donald Trump. Despite remaining cautious about long-term risks like geopolitical tensions and debt burdens, he believes those threats are ‘manageable.’
