Amazon.com closed at $260.21 on Thursday, down 2.19 percent, after an early rally tied to a new Uber Eats partnership for Prime members evaporated into a broad technology selloff. The S&P 500 fell 4.36 percent to 7,354 and the Nasdaq Composite dropped 5.52 percent to 24,315, dragging the e-commerce giant down with them. Volume surged to 83.5 million shares, roughly 117 percent above the three-month average of 38.5 million.

Midterm results shift the regulatory outlook

The Democratic Party’s gain of congressional control in the U.S. midterms introduced a new risk vector for the artificial intelligence buildout. Investors priced in the possibility that incoming Democratic leadership could push for tighter AI regulations and pause data-center construction projects that underpin the cloud infrastructure boom. For Amazon, the timing is awkward: the company is in the middle of a capital-intensive expansion of AI capacity inside Amazon Web Services.

Capital intensity shows up in the cash-flow statement

Last week’s third-quarter report already highlighted the cost of that expansion. Revenue missed estimates while capital expenditures kept climbing, producing negative free cash flow of $42.4 billion versus positive $14.8 billion a year earlier. Rising interest rates make the borrowing required to fund the buildout more expensive, and persistent inflation threatens to curb the consumer spending that drives the retail side of the business.

The long-dated bet remains intact

Management has not backed off the outlook. AWS revenue is still forecast to grow 40 percent year over year in 2027 and 2028 on the back of AI demand. The stock has appreciated 265,645 percent since its 1997 IPO, a reminder that the market has historically rewarded the patience required to digest heavy upfront investment. Whether the current political and rate environment allows that patience is the open question.
