Natixis strategists put AI productivity pass-through at the center of H2 2026 market outlook

The transmission mechanism between AI deployment and realized corporate profits is the hinge on which H2 2026 equity markets turn, according to Natixis Investment Managers' annual strategists survey. Ninety-one percent of the firm's strategists named AI as the key driver of market performance in the second half of this year. Eighty-eight percent specifically expect AI productivity gains to convert into higher corporate earnings.

The productivity-to-profit question

Whether AI spending actually moves the needle on margins is the part of this thesis that remains unproven in real income statements. The survey result suggests Natixis's own strategist bench has largely resolved that debate internally. The 88% figure on profit translation is the more telling number: sentiment surveys often produce high agreement on a broad theme while fracturing on the mechanism. Here, the mechanism itself commands near-consensus, separated from the top-line AI-as-driver figure by just three percentage points.

Geopolitical uncertainty and persistent inflation both appear as named headwinds in the survey. The strategists acknowledged them without displacing AI as the primary variable. That ordering implies the firm's analysts see AI's earnings effect as large enough to override macro noise in the second half.

US equity positioning

Sixty-seven percent of Natixis strategists expect US equities to outperform in H2 2026. Forty-two percent went further, naming the US as the single geography most likely to deliver the best returns.

The gap between those two figures reflects a split in conviction. A portion of the strategist group sees US equities beating a broad benchmark without necessarily ranking them first among all geographies covered. That is a softer read than the headline outperformance figure suggests.

Where this sits in the stack

The survey does not specify which AI spending categories the strategists see as most earnings-accretive, nor which sectors they expect to capture the most productivity lift. The 88% consensus on profit translation is a macro claim, not a sector call. Readers positioning around this view will need to resolve the stack question separately: the survey identifies the direction, not where in the income statement the gains land.

Ninety-one percent agreement on AI as the primary market driver is the single cleanest signal the Natixis Investment Managers Strategists Survey 2026 produced.
