Micron Technology briefly topped $US1 trillion ($1.4 trillion) in market value for the first time on Tuesday, crowning a dizzying rally that has cemented America’s largest memory chipmaker as one of the standout winners of the AI boom.

Micron’s shares were last up 17.4 per cent at $US881.6 after rising as much as 19.3 per cent earlier in the session, with Tuesday’s boost coming after brokerage UBS increased its price target on the stock to $US1625 from $US535 – the highest among the 46 brokerages covering the company, according to LSEG data.
