Softbank Group Corp (SFTBY.US) stock is poised to reach a new historical closing high in Japan. Previously, its key partner Oracle (ORCL.US) announced that unconfirmed performance obligations reached $455 billion at the end of August, with a 5-year contract signed with OpenAI valued at $300 billion. Softbank shares surged 9.2% on Thursday, with intraday gains reaching up to 10%, trading at 17,900 yen (equivalent to $121.38). Softbank Group Corp is one of the main supporters of the US "Stargate" project, a joint venture aimed at building artificial intelligence infrastructure for OpenAI. Oracle and Abu Dhabi-based MGX are also equity partners in this project, which could potentially involve total investments of up to $500 billion.

Andrew Jackson, an analyst at Ortus Advisors, is not surprised by investors' enthusiasm for this Japanese technology investment company's performance. He noted: "Following yesterday's 7.3% gain, Softbank Group Corp is expected to see another strong surge. Investors have already connected this development to Oracle's association—just months ago, Softbank Group Corp CEO Masayoshi Son and Larry Ellison (Oracle's Chairman) jointly attended Trump's announcement of the 'Stargate' project."

Database software giant Oracle's stock price soared 36% overnight, marking its largest single-day percentage gain since 1992. The company reported signing several multi-billion dollar contracts in its latest quarter and expects to close more such deals in the coming months. Reports indicated that OpenAI signed a $300 billion computing agreement with Oracle, representing one of the largest cloud contracts in history. The parent company of these publications has established a content licensing partnership with OpenAI.

José Torres, Senior Economist at Interactive Brokers, stated in a report: "Investors are also enthusiastic about Oracle's projections for explosive AI-related future revenue growth, which fuels belief that the technology-driven bull market has even greater room for expansion."
