What happened in the sell-off
The Nasdaq 100 fell 6.3% on November 5, according to NBC News’s market report. The S&P 500 dropped 4.4%, while semiconductor shares suffered particularly steep losses.
NBC links the selling to a combination of election results, concerns about restrictions on data-center construction and disappointing reactions to chip-company earnings. Those are reported explanations for investor behavior, rather than a controlled measurement of which factor caused each price move.
Why AI infrastructure is exposed
The report identifies Qualcomm and Arm earnings as an immediate pressure point and describes losses across chip, memory and data-center suppliers. It also reports that elected candidates in several major data-center markets have promised closer scrutiny of the industry.
That combination matters because an AI infrastructure business depends on more than demand for a model. Projects also need sites, power, financing and permission to build. Franklin’s analysis is that investors are reassessing several linked assumptions at once: whether capacity arrives on time, whether customers use it and whether the resulting revenue justifies the investment.
What the market move does and does not establish
A falling share price measures a change in market valuation. It does not directly measure model quality, installed computing capacity or the usefulness of an AI product. Likewise, a campaign promise is not yet an implemented permitting rule.
For readers following the industry, the useful next evidence is concrete: revised construction plans, enacted policy, supplier guidance and customer spending. Keep those records separate from the daily stock chart. A large one-day move can reveal how sensitive expectations have become without settling the longer-term economics of AI infrastructure.
