OpenAI CEO Sam Altman has called off a planned visit to Abu Dhabi, according to an exclusive report by Semafor, raising fresh questions about the future of the company's ambitious Stargate infrastructure project.

The trip had been scheduled for this weekend, according to MSN. No official explanation for the cancellation has been provided, but the abrupt pullback comes amid what reports describe as mounting tensions surrounding the initiative.

Stargate is OpenAI's large-scale infrastructure project, and the Abu Dhabi visit was widely seen as connected to efforts to advance that effort in the Gulf region. The cancellation signals potential friction in a partnership that has been closely watched as a cornerstone of OpenAI's global expansion strategy.

The sudden change of plans is notable given how much political and financial weight has been attached to Gulf investment in American AI infrastructure. Any slowdown in Stargate's progress would have ripple effects not just for OpenAI, but for the broader race to build out the data centers and compute power that next-generation AI systems require.

If Stargate stalls, it could affect OpenAI's ability to scale its most advanced models — and hand rivals a window to close the gap.
