AI Boom Leverage, Oil Supply Risks, Travel Boom, Healthcare Stocks, Treasury Bond Buybacks, Home Insurance Deductible & More

Investors should look beyond headline trends to hidden financing risks, supply constraints and portfolio concentration before extrapolating the AI boom or other popular market narratives.

• Hyperscalers have accumulated $1.5 trillion of lease commitments, including about $1 trillion of uncommenced leases, while annual capital spending is expected to exceed $1 trillion from 2027; OpenAI and Anthropic may represent roughly 70% of AI-related revenue at Microsoft, Amazon, Alphabet's Google and Oracle.
• U.S. refinery utilization is around 96.5%, refined-fuel inventories are about 130 million barrels below normal, and a major Gulf Coast hurricane could remove 10%–30% of refining capacity; Ukraine has reportedly disrupted roughly 30% of Russia's refining capacity.
• Americans made a record 24 million trips to Europe in 2025, held roughly $100 trillion in wealth, and around 50% now have passports versus about 5% in 1990; the author expects airlines, hotels and restaurants to benefit from continued experience-led spending.
• Healthcare outperformed technology by roughly 30 percentage points from late June to late July as the AI rally cooled, and it also outperformed by roughly 30 points in 2022 while the Nasdaq fell more than 30%, supporting its role as a less cyclical portfolio diversifier.
• Treasury buybacks will rise from $2 billion to at least $4 billion per operation, but $4 billion is only 0.01% of the $40 trillion national debt; the average interest rate on government debt rose from 2.23% in 2016 to 3.45% in 2026, increasing refinancing risk.

Takeaway: Investors should question who ultimately bears the obligations behind the AI buildout, monitor refinery and Treasury refinancing vulnerabilities, and avoid portfolios concentrated in technology by adding less-cyclical exposure, while recognizing that the travel and AI theses depend on their underlying trends continuing.
