Investing.com reported that three leading chipmakers – Micron Technology, Intel Corp and Advanced Micro Devices Inc – collectively added about $2 trillion in market value during the second quarter, reflecting a broad investor shift toward artificial‑intelligence‑related hardware.

Micron’s shares surged more than 240% in the quarter, contributing roughly $920 billion to its market capitalisation. The company disclosed that revenue in its most recent quarter more than quadrupled, driven by soaring memory prices from AI chipmakers, and its gross margin jumped to 84.9% in the third quarter from 39% a year earlier.

Intel’s stock jumped 216%, adding an estimated $480 billion to its market value. The firm is expanding U.S. chip‑fabrication capacity and benefits from renewed demand for central‑processing units as AI workloads migrate to end‑user devices.

Advanced Micro Devices saw its share price nearly triple, delivering about $615 billion of added market capitalisation and lifting the company into the 12th‑most‑valuable U.S. technology firm. AMD, while also producing graphics processors, continues to trail Nvidia in that segment.

Nvidia, the sector’s largest AI chipmaker, recorded a 15% price increase in Q2. Other notable moves in the AI‑related ecosystem included Marvell Technology climbing roughly 200%, Arm Holdings rising 134%, and the VanEck Semiconductor ETF gaining 71% – its strongest quarterly performance since the fund’s inception in 2000.

Among the broader market, Meta Platforms fell nearly 2% (its weakest showing in the group), Alphabet posted a 24% gain, while Amazon and Microsoft posted intermediate results. Individual ticker movements on the reporting day showed INTC +5.95%, MSFT +1.21%, GOOGL +1.05%, AMZN -0.75%, NVDA +2.54%, MRVL +7.22%, MU +0.68%, AMD +7.62%, META +0.08%, SMH +3.84% and ARM +3.20%.

These gains have moved Micron, Intel and AMD into the 10th, 11th and 12th positions respectively among the most valuable U.S. technology companies, underscoring the market’s rapid re‑allocation toward AI‑driven semiconductor exposure.
