Elon Musk posted that he roughly estimates around 25% of TeraFab’s AI computing power output will be allocated to Tesla Optimus, while approximately 75% will go toward AI spacecraft. Earlier reports noted Tesla announced its Terafab plan would launch in Texas, with the goal of achieving over 1 terawatt of annual computing power.

Google parent company Alphabet’s massive bond offering has attracted around $115 billion in subscription demand. Earlier reports noted that Alphabet is preparing to issue a new round of US corporate bonds, targeting a maximum raise of $25 billion.

Iranian media Fars News reported that Iran’s parliament is reviewing a draft bill aimed at strengthening control over transit rules in the Strait of Hormuz and Persian Gulf. Key proposals include: banning vessels linked to the U.S., Israel and other hostile countries from transiting; restricting the transport of civilian and military goods related to Israel; limiting ship traffic related to operations against the "Axis of Resistance"; and denying navigation access to entities that owe compensation payments to Iran. Violations will be subject to fines of up to 20% of the value of the goods. The bill is still under review and has not yet been approved. (Jinshi)

Tesla (TSLA) announced earlier this year that SpaceX and it had launched the "Terafab" project—the world’s largest chip manufacturing initiative, integrating logic chips, memory chips, and advanced packaging technologies in a single facility. In April, Tesla broke ground on a new R&D wafer fab at the North Campus of its Texas Gigafactory, which served as the precursor to Terafab. Today, the company formally announced that Terafab will be located in Grimes County, Texas. The facility will be an advanced semiconductor wafer fab designed to bridge the massive gap between current global chip supply capacity and future computing demand. SpaceX and Tesla’s combined chip requirements are projected to exceed 1 terawatt (TW) of computing power, a scale far outstripping today’s global supply capacity. The company expressed deep gratitude to its existing chip suppliers and encouraged them to expand production capacity where feasible, adding that the widening gap between future supply and demand is the core reason for the Terafab project. Terafab aims to produce new computing power at an unprecedented scale and speed. The project plans to build a vertically integrated factory spanning over 100 million square feet, covering the manufacturing, packaging, and testing of advanced logic and memory chips. Centralizing these processes in one location will facilitate rapid iterative improvements and accelerate the deployment of new computing capabilities. (Jinshi)
