Wall Street Bets On AI Boom

Despite a brief pullback lately, chip stocks have generally been on a tear. AMD continues to benefit from the AI-driven semiconductor boom, with Wall Street becoming increasingly bullish on the chipmaker's growth prospects.

Earlier this week, Goldman Sachs raised its price target on AMD to $640 from $450, while maintaining a ‘Buy’ rating, according to The Fly. The move follows another major upgrade in May, when the firm lifted its target from $240 to $450.

Goldman expects AMD to gain market share in AI infrastructure as demand for GPUs and AI accelerators remains strong. The company is positioning its MI-series accelerators as an alternative to Nvidia’s products, while heavy AI spending by cloud giants such as Microsoft, Amazon, and Google continues to fuel demand.

Cantor Fitzgerald is even more optimistic, raising its target on AMD to $700 from $500 and reiterating an ‘Overweight’ rating last week. The firm believes the AI infrastructure buildout will drive a multi-year semiconductor growth cycle, with industry revenue potentially exceeding $3.5 trillion by 2030.

MU’s Footsteps To Follow

Micron (MU) first crossed the $1 trillion market capitalization milestone on May 26, 2026. At the time of writing, its shares were up 7%, valuing the chipmaker at about $1.15 trillion after it increased its planned U.S. investment through 2035 to $250 billion from $200 billion.

If AMD shares meet Cantor Fitzgerald’s target, its market capitalization would also cross $1 trillion, considering the number of outstanding shares remains the same.
