Debate heats up on whether AI spending is delivering real economic returns or just future promises.

Leading investors debated if AI investments are currently boosting company profits or if Wall Street is overestimating future gains. Chamath Palihapitiya warned companies must prove AI spending yields real revenue within 500 days, citing no clear evidence of improved S&P 500 margins from AI yet. Others, like Brad Gerstner and Jason Calacanis, argue AI is already improving profitability and operational efficiency, especially in startups and tech giants like Microsoft and Alphabet, which report strong AI-driven revenue growth despite high infrastructure costs. The key question remains whether AI will broadly enhance productivity and justify massive spending in the long term.
