Oracle's stock soared nearly 9% on Wednesday, propelled by surging demand for its cost-effective cloud infrastructure services, particularly from AI applications. The surge could boost the company's market valuation by over$28 billion, adding to its current$340 billion valuation. With an 18% increase in shares since the beginning of the year, Oracle is capitalising on the momentum of its cloud infrastructure unit, which offers computing and storage services to businesses at competitive prices, positioning itself against major rivals like Google, Microsoft, and Amazon.

Oracle's cloud infrastructure has garnered attention from AI startups, including Elon Musk's xAI, thanks to its affordability compared to competitors. In a strategic move, Oracle recently announced partnerships with ChatGPT-maker OpenAI and Google Cloud to expand its cloud infrastructure offerings. That collaboration strengthens Oracle's position as an AI platform and extends its database services distribution, as Evercore analyst Kirk Materne highlighted.

While Oracle's forward earnings estimates stand at 19.59 times, lower than those of its major competitors, its fourth-quarter results missed expectations. Due to increasing competition from more cost-effective alternatives, the company faces challenges in its legacy database and enterprise resource planning (ERP) software business. Morningstar analyst Julie Sharma suggests that Oracle may experience customer churn as businesses undergo significant digital transformations, opting for cheaper database and ERP solutions over Oracle's offerings.
