Citigroup warns AI slowdown could pressure stock market gains
Cryptobriefing.com reports that Citigroup analysts are warning a slowdown in AI model development could pressure equity gains. The bank suggests this shift might trigger downward earnings revisions, which have been the engine of US stock performance through 2026. On September 13-14, AI-linked stocks including SoftBank and Intel sold off following comments from key industry leaders.
Anthropic CEO Dario Amodei and OpenAI’s Sam Altman both called for a more measured pace in AI development. Their unified stance introduced uncertainty into a market that had priced in relentless progress. Citigroup’s research spanning mid-2025 through 2026 highlights vulnerability to delays in AI productivity benefits.
The bank describes the current setup as a “boom” rather than a bubble. Strategists specifically flagged risks of multiple compression in software sectors with stretched valuations. The anticipated productivity improvements have been priced in with little room for disappointment. If gains do not materialize as expected, implications could extend beyond tech into broader indices.

The Cumulative Volume Delta (CVD) for the 24-hour close is +$242,551, reflecting consistent accumulation.
