Kristalina Georgieva, the Managing Director of the International Monetary Fund, stated in June 2026 that advanced artificial intelligence (AI) models could be used to compromise the financial system if safeguards are not implemented. Georgieva cited Anthropic's Mythos model as an example, following its release to U.S. corporate partners.

In April 2026, Anthropic announced its new AI model, Mythos. Anthropic shared the Mythos model with a dozen trusted U.S. corporate partners but did not release it publicly. The company stated that Mythos is capable of exploiting cracks in the software running power grids, major banks and other institutions. Georgieva said, "Advanced AI models can be weaponized by bad actors to 'destroy the financial system' without safeguards in place." She added, "What we recognize is that Mythos is just the beginning, there will be more like it."

Tobias Adrian, director of the Monetary and Capital Markets Department at the International Monetary Fund, expressed concern about corporate borrowing rather than an AI bubble during the annual European Central Banking gathering. Adrian cited that major tech firms are increasing their debt. "What is quite worrisome from a financial stability perspective is that the major tech firms are starting to leverage up themselves," Adrian said. He also said, "There was a potential maturity mismatch in between the duration of the physical assets and the duration of the debt."

Amazon, Alphabet, Meta, Microsoft, and Oracle collectively issued $159 billion in corporate bonds during the first five months of 2026. This amount exceeds these companies' total borrowing over the past five years, according to Dealogic. In June 2026, Nvidia issued $25 billion in corporate bonds, marking its first such issuance since 2021. Alphabet announced in June 2026 its plans to raise $85 billion in equity to finance its AI buildout.

A J.P. Morgan analysis from May 2026 indicated that 60% of data center capacity scheduled for completion by 2027 had not yet begun construction, and 7% was delayed. A maturity mismatch occurs when firms rely on short-term debt to finance long-term assets.
