🔹 AI Tracking Trillions: Examining Assumptions Behind the Scale of the 2026 AI Build-Out

The article discusses the factors influencing AI infrastructure investment, highlighting that cost per megawatt ($/MW) and chip architecture choices, such as the shift from NVIDIA GPUs with 75% gross margins to custom ASICs, significantly impact total costs. The elasticity of demand determines whether cheaper compute reduces spending or increases usage. Elongation—delays caused by power interconnection queues, permitting, labor shortages, and equipment lead times—mainly affects project timing and volatility rather than aggregate investment size. Factors like training versus inference mix, rising memory per accelerator, and behind-the-meter power have limited impact on the estimated ~$7.6 trillion AI infrastructure spend.

🔹 Representation Homogeneity Linked to Systemic Instability in AI-Dominated Financial Markets, Study Finds

The paper by Yimeng Qiu and Qiwei Han, submitted on 14 April 2026, examines how similarity in informational representation among AI trading agents can cause systemic instability in financial markets. Using a structural multi-agent market model calibrated with high-frequency microstructural moments, the authors distinguish between representation homogeneity and forecast overlap. They demonstrate that increased representation homogeneity compresses forecast disagreement under stress, amplifies synchronization in beliefs and positions, and leads to volatility clustering, liquidity stress, elevated tail risk, and hidden leverage accumulation that collapses during shocks. The findings support macroprudential policies to monitor diversity in AI market information processing.
