David Hay — Deficits, doubts, and data centers

"Both of these positive factors are likely to ebb… but a more enduring source of vitality is the productivity acceleration from AI."

One-line take: A short macro "Haymaker Daily" weighing crosscurrents — no stock picks. The negatives: depressed consumer sentiment, sluggish car/home sales, surging gasoline/electricity prices, decelerating tax receipts, and pessimistic CEOs (only 15% see improvement, 47% see worsening). The buoyancy: AI data-center construction + a federal deficit up $365B to >$2T (and a planned +$500B in military spending) — but both are likely to ebb if the data-center build hits a wall (≈ half of planned centers delayed/cancelled on power shortages) and as interest outlays bite with the 10-yr Treasury threatening >5%. The durable offset: a dramatic AI-driven productivity acceleration (per JPM's Cembalest, Real GDP & Gross Domestic Output have jumped since ChatGPT in late 2022) — critical given missing US labor-force growth, and "in its early days." Feeds the master macro viewpoints (deficits, AI productivity, rates).
