JPMorgan aggressively double-upgrades another AI stock by 41%

I rarely see double-upgrades from Wall Street. JPMorgan analyst Richard Choe moved an AI stock directly from Underweight to Overweight on Sep. 14, skipping a neutral rating entirely, in a note shared with TheStreet. JPMorgan may have underestimated this one. Now it's slamming the brakes, making a U-turn and hitting the gas. The double-upgrade is JPMorgan's second such move in the AI-adjacent space in recent months. The bank made the same jump with Circle Internet Group, a fintech and digital financial services company tied to the growing stablecoin economy in Nov. 2025, Yahoo Finance reported. Before that, Lanxess, a German specialty chemicals maker, got the double upgrade in March 2026.
