Several major US banks recently reported record quarterly results, with trading activity and receivables both reaching new highs, driven in part by the artificial intelligence boom. However, behind the strong financial performance, multiple Wall Street executives have issued warnings about the current overheating in the AI sector, suggesting the industry may be caught in irrational exuberance.
On Tuesday, JPMorgan Chase, Goldman Sachs, and Citigroup reported third-quarter results showing robust trading and investment banking businesses were key drivers of profit growth. Executives from several banks anticipate the current active trading environment will likely continue, and investment banking pipelines will remain solid.
Bank of America’s stock rose 4% in pre-market trading. As of Tuesday, the stock had gained 14% year-to-date, outperforming the S&P 500 Financials Index, which rose 10% over the same period. The bank’s trading business also exceeded market expectations, primarily due to a 14% increase in equities revenue to $2.27 billion; fixed income revenue also rose 4.6% to $3.08 billion. Overall market trading volumes remained stable in the third quarter, as investors continued adjusting their positions around the Trump administration’s fluctuating tariff policies and various geopolitical developments.
During this earnings season, banks widely showcased practical applications of AI technology in their internal operations, such as Bank of America’s virtual financial assistant “Erica” and JPMorgan’s use of AI for cost control. While institutions are optimistic about AI’s long-term potential, many executives expressed caution. Citigroup CFO Mark Mason noted that, judging by current stock valuations and price-to-earnings ratios in some sectors, the market is already showing signs of froth and overvaluation. Goldman Sachs CEO David Solomon recalled the history of the dot-com bubble, warning of risks associated with massive investments in AI infrastructure. He believes that while some AI projects will succeed in the future, others will face challenges.
Goldman Sachs COO John Waldron, speaking at a forum in Washington, stated that the US economy is placing “a pretty big bet” on AI to drive future growth. However, he emphasized that it is still “too early” to determine whether an AI bubble has formed, and the ultimate outcome could be very positive but remains uncertain.
Despite differing views, the banking industry continues actively deploying AI technology. Morgan Stanley CFO Sharon Yeshaya pointed out that current AI applications have only touched the “tip of the iceberg” of its potential, with more diverse applications to come. JPMorgan’s Jeremy Barnum also acknowledged that the bank has introduced AI in some business areas, but the returns are “not always quick or easy,” with truly significant results expected to emerge gradually in the future.
