ASML says its planned supply of advanced chipmaking machines will not fully meet customer demand in 2027 and 2028, even as capacity expands. With customers already discussing orders for 2029 and 2030, manufacturing equipment could become one of the AI boom's most important bottlenecks.

Microsoft plans to deploy potentially more than one million Maia 300 chips next year as it pushes deeper into its own AI infrastructure. With more than $175 billion in expected capital spending, the bigger question is how Microsoft’s shift toward in-house silicon could change where AI money flows.

Amazon is reportedly considering a $7 billion acquisition of Decart, a startup whose technology extends beyond AI video into software that operates across competing AI chip platforms. The potential deal raises bigger questions about Amazon Web Services' AI strategy, the price Amazon may ultimately pay, and whether the acquisition will happen at all.

Nvidia may be looking beyond its dominant position in AI chips as it discusses a possible deal with Reflection AI. The unanswered question is whether those talks become a full takeover—or a different kind of partnership that pushes Nvidia deeper into AI models.

SpaceX's reported $8 billion spectrum acquisition sent T-Mobile, Verizon and AT&T shares down about 6% after hours, raising questions about the future of America's wireless market. With Starlink Mobile preparing for broader competition, FCC approval is now a key development to watch.

Samsung’s AI-driven memory business is producing extraordinary profits, yet its shares fell about 2.4% anyway. The market’s attention is shifting from whether AI demand is real to whether today’s exceptional memory margins can last through Samsung’s October 29 earnings report.

SpaceX reportedly wants $40 billion in financing to fund Nvidia AI chips, showing how quickly the AI infrastructure race is becoming a capital-markets story. The next question is what lenders and investors will demand to finance the buildout.

Tesla has secured $30 billion in new borrowing capacity while planning more than $25 billion of capital spending this year—but none of the new credit has been drawn yet. The next earnings report should reveal whether Tesla’s spending and free cash flow leave that financial firepower untouched or make it increasingly important.

Nvidia expanded its buyback authorization by $150 billion as its shares rose about 1.6% while the broader market fell. The headline number is enormous, but the more important question is how aggressively Nvidia actually puts that authorization to work.
