Micron Technology briefly overtook Meta Platforms and came within touching distance of surpassing Tesla on Thursday, marking another milestone in the artificial intelligence-driven rally that has transformed the fortunes of memory chipmakers and reinforced their central role in the global AI infrastructure race.
The surge came after the U.S. memory chipmaker delivered stronger-than-expected quarterly guidance, highlighting how demand for high-performance memory used in AI systems continues to outstrip supply and drive unprecedented long-term customer commitments.
Micron shares rose as much as 18.4% to $1,236, lifting the company’s market capitalization to approximately $1.398 trillion, narrowly ahead of Meta’s $1.392 trillion valuation and briefly approaching Tesla’s $1.4 trillion market value before fluctuating during trading.

The rally follows Micron’s blockbuster fiscal third-quarter earnings released on Wednesday, where the company forecast fourth-quarter revenue well above Wall Street expectations and disclosed that customers had committed $22 billion through long-term supply agreements designed to secure future memory chip deliveries.
The agreements underscore how hyperscale cloud providers, AI model developers, and enterprise customers are increasingly locking in supplies of high-bandwidth memory (HBM) and other advanced memory products amid expectations that demand will remain elevated for years.
Unlike previous semiconductor cycles that were often characterized by sharp boom-and-bust swings, industry analysts say AI infrastructure spending is creating a more durable demand environment, with customers willing to sign multi-year contracts to guarantee access to critical components.
Micron’s management said many of those contracts extend three to five years, providing greater revenue visibility while reducing exposure to future pricing volatility. The company also expects approximately 40% of future revenue to come from long-term agreements that include minimum pricing provisions, giving investors greater confidence that profit margins can remain resilient even if memory markets eventually cool.
The latest rally represents a dramatic turnaround for Micron, which for years struggled through cyclical downturns driven by oversupply in traditional PC and smartphone markets. Today, the company has become one of the biggest beneficiaries of the global AI investment boom, as advanced AI servers require vastly larger quantities of memory than conventional computing systems.
Micron disclosed that it has signed 16 long-term agreements with customers spanning industries including cloud computing, data centers, and automotive manufacturing. The agreements lock in sales commitments for periods ranging from three to five years.
RBC analysts said the agreements increase confidence that the current memory upcycle has further room to run.
“Our base case is for the current upcycle to continue through 2027, and SCAs give us added conviction regarding sustainability. We raise estimates, raise PT, and reiterate Outperform,” the firm wrote following the earnings release.
Modern AI clusters powered by graphics processors from companies such as Nvidia rely heavily on high-bandwidth memory to rapidly move massive datasets during model training and inference. That surge in demand has tightened supplies across the memory industry, pushing up prices for DRAM and NAND products while boosting earnings for manufacturers.
The shift has also reshaped the competitive landscape of the semiconductor industry.
Micron crossed the $1 trillion market capitalization milestone on May 26, joining a select group of technology companies whose valuations have been propelled by artificial intelligence. The milestone came shortly after South Korea’s Samsung Electronics also entered the trillion-dollar club, reflecting renewed investor enthusiasm for memory manufacturers after years in which chip designers captured most of the market’s attention.
The emergence of memory companies among the world’s most valuable technology firms shows that AI spending is broadening beyond processors to encompass the entire semiconductor supply chain.
While Nvidia remains the dominant supplier of AI accelerators, the industry’s rapid expansion is creating significant opportunities for companies producing memory chips, advanced packaging technologies, and networking components needed to build increasingly powerful AI infrastructure.
For investors, Micron’s latest valuation milestone is believed to be a signal that the AI trade is evolving. Rather than focusing solely on companies designing AI chips, markets are increasingly rewarding businesses supplying the critical technologies that enable hyperscalers and enterprises to deploy large-scale AI systems.
With major technology companies continuing to commit hundreds of billions of dollars to AI data centers, demand for advanced memory remains one of the strongest themes supporting the semiconductor industry’s historic expansion.
