Concerns Mount Over AI Investment Bubble and Potential Financial Crisis

Wall Street and Silicon Valley's collaboration on high-risk "private credit" deals is fueling an AI buildout bubble. The unregulated private credit sector, now managing $1.6 trillion, is financing AI infrastructure with questionable terms and mismatched asset lifecycles. Special Purpose Vehicles (SPVs) are used to fund data centers, relying on Big Tech firm payments for debt repayment. Rapid GPU depreciation and extended depreciation schedules lead to overstated revenues and potential "stranded assets." Insufficient sector cashflow raises concerns, with some companies losing billions per quarter. Experts warn this has echoes of the 2000s housing bubble and unregulated lending of the 1920s. Private equity, REITs, and banks are also involved, potentially impacting individual investors' 401(k) plans.
