Micron's HBM (High Bandwidth Memory) backlog is completely sold out, driving earnings outperformance and analyst price target upgrades to $1,600+.

Micron Technology (MU) is experiencing an historic rally, driven by massive demand for its high-bandwidth memory (HBM) chips in AI infrastructure.

The primary catalyst is extreme optimism ahead of Micron's Fiscal Q3 earnings release on Wednesday, June 24, 2026, after market close. Consensus estimates project earnings per share of around $19.72 on revenue of $34.52 billion, representing year-over-year earnings growth exceeding 900%. Management has previously guided for record gross margins near 81%, and Wall Street is focused on whether Micron's pricing power remains intact. Ultra-bullish investment banks including UBS and Cantor Fitzgerald have pushed price targets to $1,500–$1,600. The options market is currently pricing in a roughly 17% implied move in either direction following the earnings announcement.

Both Micron and rival SK Hynix have reported that their high-bandwidth memory production capacity is entirely sold out through calendar year 2026, locked in by major players including Nvidia for next-generation AI accelerators such as the Blackwell B200. Market sentiment received an additional boost ahead of earnings following a surprise partnership with AI lab Anthropic.

While some bears warn that Micron's massive capital expenditure program—expected to top $25 billion for the full year—could eventually trigger oversupply in 2027 or 2028, the current structural expansion of agentic AI is keeping demand substantially ahead of supply.
