BofA's Quinlan: AI Infrastructure Buildout Keeps Him Bullish on U.S. Stocks After July Jobs Report

The Quick Take

• Merrill Lynch's Head of Market Strategy Joe Quinlan remains bullish on U.S. stocks, citing the AI infrastructure buildout as the primary structural growth driver
• Quinlan delivered his market view in reaction to the July U.S. jobs report, arguing that AI investment spending is creating a durable growth foundation beyond the cyclical employment cycle
• The AI buildout thesis positions technology infrastructure, semiconductors, and energy as key beneficiaries of sustained capital investment in the coming years

Merrill Lynch and Bank of America's Head of Market Strategy Joe Quinlan articulated a bullish U.S. equity stance on Bloomberg's weekend programming, anchoring his view on the structural AI infrastructure buildout that he believes transcends normal business cycle dynamics. The July jobs report, which provided the market context for Quinlan's commentary, was interpreted through an AI-positive lens: even if employment momentum moderates cyclically, the sustained capital expenditure by hyperscalers and AI infrastructure providers creates a durable demand floor for technology, construction, energy, and semiconductor sectors.

Quinlan's AI buildout thesis has direct implications for sector allocation. The infrastructure investment cycle — data centers, semiconductor fabs, power grid upgrades, and fiber networks — creates multi-year capex streams that support industrial, materials, and energy names beyond the obvious technology winners. This broader market bullishness, rooted in AI rather than consumer or financial cycle dynamics, represents a departure from traditional market strategy frameworks: it suggests that the 2026-2028 capital expenditure wave could sustain earnings growth even if the consumer cycle softens or rates remain elevated.

Investors should track the quarterly capex disclosure from hyperscalers including Alphabet, Amazon, Microsoft, and Meta as the primary leading indicator of AI buildout momentum. If spending commitments rise above consensus estimates, Quinlan's bull case strengthens; if capex growth decelerates, the structural thesis weakens. The macro variable is power grid capacity: AI data centers are electricity-intensive, and utility grid constraints in key U.S. markets could bottleneck the buildout pace, creating a supply-side governor on the AI capex cycle despite sustained demand.
