SoftBank Group shares fell as much as 12.5% on Monday. The stock reached its lowest level since August 2025. This decline followed reports that Oracle and OpenAI scrapped plans to expand a flagship AI data center in Texas. The facility was a central component of the 'Stargate' artificial intelligence initiative.
Investor anxiety increased after S&P Global Ratings revised SoftBank’s credit outlook to negative from stable on March 3. The agency identified the group's massive additional investment in OpenAI as a risk to asset liquidity. S&P also cited concerns regarding SoftBank's overall financial capacity.
SoftBank’s credit default swaps have widened due to project delays and heightened financial scrutiny. This movement signals a rising perception of risk among market participants.
