SpaceX and Google race to build AI data centers in space
A new chapter in the competition for AI infrastructure has emerged with plans to operate data centers in Earth orbit. SpaceX, led by Elon Musk, has filed with the FCC for a constellation of up to one million satellites functioning as an orbital data center, powered by solar energy and connected via lasers. Google is pursuing a similar initiative called 'Project Suncatcher,' planning prototype tests by 2027. Jeff Bezos of Amazon and Blue Origin also advocates for space-based data centers, citing environmental benefits. However, the article highlights a major technical hurdle: cooling in a vacuum, which requires huge radiators and remains unsolved at scale. Both SpaceX and Google are investing in research, but the technology is far from market readiness.
Major tech companies are exploring orbital AI data centers, which could reshape AI infrastructure, but immediate impact on AdTech is low.

Fed Sees AI Boom as Inflation Driver
The Federal Reserve has identified the massive expansion of AI infrastructure as a contributing factor to persistent inflation, according to the minutes of its latest interest rate meeting. The Fed raised its benchmark interest rate for the first time since 2023, and the minutes reveal that committee members observed that 'strongly rising AI-related investments' are adding to inflationary pressures. While tariffs and energy prices remain significant factors, the AI boom is also supporting the economy through robust corporate investment. The report highlights that the Fed's preferred PCE inflation measure rose to 3.8% in August, with core inflation at 3.4%, well above the 2% target. A majority of members consider it likely appropriate to raise rates again by the end of the year, depending on incoming data. The role of AI as a primary driver of core goods prices is noted by 'several' members, not a majority, indicating a nuanced view.
Alexa Plus Bug: Speakers Sing 'La' for 10 Minutes
Multiple users report that Amazon's AI-powered voice assistant Alexa Plus spontaneously begins repeating the syllable 'la' for extended periods, resembling eerie singing. The issue occurs during or after conversations, with some users capturing videos of the behavior. One user claims Alexa denied singing and couldn't hear the playback. Amazon has acknowledged the bug, stating it affects a small number of Alexa Plus users and that a fix is in development. Suggested workarounds include restarting the device or downgrading to the classic Alexa.
Musk's Grok Bot to Use Rival AI Models Like Claude
Elon Musk announced that Grok Bot, an agent app from his AI unit (formerly xAI, now part of SpaceX and recently renamed SpaceXAI/SpaceXSI), will no longer rely solely on its own Grok models. Instead, it will pick 'the best back-end model for the respective task,' citing examples such as Anthropic's Claude Opus 5.5, Midjourney, and Suno. The announcement, first reported by The Information, follows user complaints about access issues. This strategic shift acknowledges that xAI's models don't lead in all areas—for instance, Claude Opus 5.5 outperforms competitors on the Artificial Analysis ranking. The move mirrors a broader industry trend of multi-model routing, as seen with Microsoft's Copilot and Perplexity, and comes despite reports of SpaceX planning $40 billion in debt for Nvidia chips.
