Intel Down 25%, Reddit Down 20%, Amazon Down 6.3% as AI Bills Spook Investors

Intel shares plunged 25% in premarket trading after the chipmaker guided Q4 revenue to $15–16 billion, well below the $17 billion analysts expected. The rout didn't stop there: Reddit fell nearly 20% and Amazon dropped about 6.3%, a day after Alphabet suffered the worst single-day post-earnings decline in its history.

Alphabet (Nasdaq: GOOG) started the carnage. The Google parent's stock fell 12.29% in one session after its latest quarterly report, wiping out more than half a trillion dollars in market value. Two factors drove the sell-off: a significant increase in Google's negative cash flow from its AI buildout, and Search division revenue that came in below expectations, fueling fears of disruption by AI chatbots. On Thursday, GOOG stabilized, trading down roughly 0.8%.

Why is Intel down 25%?

Intel (Nasdaq: INTC) reported its Q3 2026 results Wednesday, and investors didn't like the outlook. As CNBC noted, the company guided its current Q4 below expectations, driven primarily by a slowdown in PC sales. The average cost of a personal computer is surging thanks to skyrocketing memory prices, and when PC prices go up, consumers buy fewer of them.

Intel expects Q4 revenue between $15 billion and $16 billion. Analysts had expected $17 billion.

Why is Reddit down 20%?

Reddit (NYSE: RDDT) also reported Q3 2026 results Wednesday. The stock plummeted on news that its search referral traffic—mainly from Google—is "down meaningfully" in the current Q4.

As Google embraces AI search results, fewer Google users see or click Reddit referral links, and traffic to the social media site has fallen. In response, Reddit says it will now require users to be logged in to see its content.

Why is Amazon down 6.3%?

Amazon (Nasdaq: AMZN) reported Q3 revenue just under $202 billion with EPS of $1.89. CNBC noted both figures came in below analyst expectations.

The bigger issue: Amazon posted negative free cash flow of $42.4 billion for the trailing 12 months, largely from continued capital expenditures on its AI buildouts. Google's negative free cash flow disclosure a day earlier triggered that stock's plunge.

The damage spread fast. The sell-off in Intel, Reddit and Amazon pushed tech-heavy Nasdaq futures down 2.4% and S&P 500 futures down 1% in premarket trading.

Is this the AI reckoning?

One common thread runs through all three stories: AI. Amazon's buildout is producing significant negative free cash flow even as it keeps spending on hyperscaling ambitions. Reddit is losing search referrals because Google's AI overviews and AI answers are absorbing clicks. Intel is suffering because RAM-hungry data centers are driving memory prices sky-high, pushing consumers to delay PC purchases.

It's too early to call it an investor-led AI reckoning. But this week's falls in Google, Amazon, Intel and Reddit show investors are increasingly concerned about AI's impact on bottom lines.

For hyperscalers like Google and Amazon, investors now want to see a return on investment. Both companies may know how to build great AI products, but investors are increasingly worried that no one has cracked how to make AI profitable.

The hundreds of billions tech giants are spending on AI buildouts—mainly data centers—will need to be paid back eventually. If those buildouts keep generating negative free cash flow, investors will keep asking how these massive companies plan to pay their bills when they come due.
