Top 5 Global AI Stories: September 24, 2025 – OpenAI, Oracle, and SoftBank Announce 0 Billion Stargate Expansion as AI Infrastructure Boom Accelerates

Wednesday, September 24, 2025, emerges as a defining moment for global artificial intelligence infrastructure as OpenAI, Oracle, and SoftBank announce five new U.S. data center sites under the Stargate platform, bringing total planned capacity to nearly 7 gigawatts with over $400 billion in investment over three years—ahead of schedule to meet the full $500 billion, 10-gigawatt commitment by year-end. This unprecedented expansion, featuring sites in Texas, New Mexico, Ohio, and the Midwest, represents the largest private AI infrastructure initiative in history, creating over 25,000 on-site jobs while positioning America as the global leader in AI computing capacity. The day simultaneously witnesses Micron Technology’s explosive 46% revenue surge driven by artificial intelligence memory demand, with the company providing bullish guidance of $3.75 earnings per share as high-bandwidth memory (HBM) sales reach a $6 billion annual run rate. These developments coincide with innovative breakthroughs including Rocket Health’s launch of the world’s first AI-powered voice journaling app addressing India’s mental health crisis, where only one psychiatrist serves every 100,000 people, and Hitachi’s strategic acquisition of German AI firm synvert to accelerate Agentic and Physical AI development through its 550-person specialist team. These convergent developments collectively demonstrate artificial intelligence’s evolution across infrastructure investment, semiconductor demand, healthcare innovation, and enterprise transformation that will define technological and economic leadership throughout the remainder of 2025.

1. OpenAI, Oracle, and SoftBank Expand Stargate with 0 Billion Multi-Site Development

Five new U.S. data centers accelerate path to 10-gigawatt capacity ahead of 2025 deadline, creating 25,000 jobs across strategic locations

OpenAI, Oracle, and SoftBank announced on September 23, 2025, five new U.S. artificial intelligence data center sites under the Stargate platform, bringing combined capacity to nearly 7 gigawatts with over $400 billion in investment planned over the next three years, putting the initiative ahead of schedule to achieve its full $500 billion, 10-gigawatt commitment by the end of 2025. The expansion includes three Oracle-developed sites in Shackelford County, Texas; Doña Ana County, New Mexico; and an undisclosed Midwest location, plus two SoftBank-partnered facilities in Lordstown, Ohio, and Milam County, Texas, with potential for an additional 600-megawatt expansion near the flagship Abilene site. Sam Altman, CEO of OpenAI, emphasized that “AI can only fulfill its promise if we build the compute to power it. That compute is the key to ensuring everyone can benefit from AI and to unlocking future breakthroughs”.group+3

The new sites were selected through a rigorous nationwide process launched in January, with OpenAI, Oracle, and SoftBank reviewing over 300 proposals from more than 30 states, while the Oracle partnership alone represents over $300 billion in collaboration over five years. The flagship Stargate campus in Abilene, Texas, is already operational on Oracle Cloud Infrastructure (OCI), with Oracle delivering the first NVIDIA GB200 racks in June and early training and inference workloads already underway using the new capacity to advance OpenAI’s next-generation research. SoftBank Chairman and CEO Masayoshi Son stated that “Stargate is harnessing SoftBank’s innovative data center design and energy expertise to deliver the scalable compute that powers AI’s future”.sharecafe+2

The strategic implications position the United States as the undisputed global leader in AI infrastructure capacity while demonstrating unprecedented private sector commitment to artificial intelligence development. The initiative, originally announced alongside President Trump at the White House in January, has advanced more quickly than expected due to administration policies that attracted additional partners and momentum. The combined sites are expected to create over 25,000 on-site jobs and tens of thousands of additional positions across the U.S., with each facility requiring approximately 900 megawatts of electricity to power hundreds of thousands of specialized AI chips, fundamentally reshaping America’s energy and technology landscapes.group

2. Micron Technology Surges on AI-Driven Memory Demand with Record Guidance

Revenue jumps 46% to exceed $11 billion as high-bandwidth memory sales hit $6 billion annual run rate, validating AI infrastructure investment thesis

Micron Technology Inc. reported exceptional fourth-quarter 2025 results on September 23, 2025, with revenue jumping 46% year-over-year to exceed $11 billion, significantly outperforming Wall Street expectations while providing bullish guidance of approximately $3.75 earnings per share for the current quarter compared to analyst projections of $3.05. The memory chip giant’s performance was driven by explosive demand for high-bandwidth memory (HBM) used in AI accelerators, with HBM revenue surging more than sixfold to $2.1 billion in the quarter while reaching a $6 billion annual run rate—nearly 50% quarter-over-quarter growth. DRAM sales, representing nearly four-fifths of company revenue, climbed 63% year-over-year to $8.7 billion, demonstrating the sustained strength in AI-related memory demand.businesstimes+5

The company’s strategic focus on HBM products has positioned it as a key beneficiary of the AI boom, with analysts projecting the HBM market could reach $100 billion by 2027 from under $5 billion in 2023, driven by insatiable demand for memory chips that prevent expensive GPUs from sitting idle during AI training and inference workloads. Micron revealed aggressive plans to ramp up HBM production, projecting full capacity well into 2026, while the transition to more advanced products like HBM3E and upcoming HBM4 is expected to keep DRAM supply tight due to limited clean room availability. The premium pricing of HBM highlights its strategic importance, with analysts estimating average selling prices of $1.49 per unit—nearly four times traditional DRAM pricing.bloomberg+3

The strategic implications extend beyond individual company performance to validation of the broader AI infrastructure investment thesis, with Micron’s results serving as a bellwether for semiconductor sector health amid massive AI deployment. Analysts have revised earnings estimates significantly upward, with calendar year 2025 EPS projections reaching approximately $9.00 well above consensus of $7.59, while 2026 estimates have been raised to $14.00 compared to consensus of $11.68. Micron’s success demonstrates how AI development is creating new winners across semiconductor supply chains while emphasizing the critical importance of memory infrastructure in enabling artificial intelligence breakthroughs that require unprecedented computational resources.investing
