Alphabet Sinks 6%, Amazon Slides 4% Amid AI Capex Anxiety Across the Hyperscalers

Alphabet (NASDAQ:GOOGL) stock is down 6% in Monday midday trading, sliding to around $346. The selloff in Alphabet shares is the most prominent move among the hyperscalers today.

Caught in the same theme, Amazon (NASDAQ:AMZN) stock is down 4% to around $234. Meta Platforms (NASDAQ:META) and Microsoft (NASDAQ:MSFT) shares are also lower, though by smaller margins.

The catalyst is growing investor unease over the sheer scale of AI capital spending across the hyperscalers. The selling is playing out against a broadly risk-off tape tied to geopolitical headlines out of Iran.

AI Capex Anxiety Sparks Hyperscaler Selloff

Alphabet guided 2026 capital expenditures to a range of $175 billion to $185 billion, while Amazon flagged about $200 billion in 2026 capex across the company. Combined with Microsoft, Meta Platforms, and Oracle (NYSE:ORCL), aggregate hyperscaler capex tops $452 billion for 2026.

Free cash flow is bearing the brunt. Alphabet’s Q1 2026 free cash flow fell 47% year over year (YoY) to $10.12 billion, while Amazon’s trailing free cash flow has dropped 95% to $1.2 billion. The bears worry monetization is lagging the buildout.

Alphabet-Specific Pressures

Alphabet stock is also feeling short-term pressure from a reported departure of a key Google DeepMind scientist, feeding concerns about AI talent retention. The r/stocks community has fixated on the theme, with a widely upvoted thread titled “Google loses two top AI researchers to OpenAI and Anthropic” drawing 470 upvotes and 231 comments by Monday morning.

Reddit sentiment on Alphabet currently reads 32 (bearish), a sharp reversal from bullish readings near 72 earlier in the week. The Alphabet stock dip is so far attracting only muted buyer interest.

Amazon Caught in the Crossfire

Amazon stock is moving on the shared capex theme. AWS grew 28% in Q1 2026 to $37.59 billion, its fastest pace in 15 quarters, yet Q1 capex hit $44.2 billion, up 77% YoY.

The Polymarket crowd is treating today’s move as a continuation. The market for “Amazon (AMZN) Up or Down on June 22?” prices a down close at 98% probability, while the most likely week-ending level for Amazon stock clusters near $232.

The bull case still rests on franchise strength. Amazon CEO Andy Jassy framed the spend as targeting “seminal opportunities like AI, chips, robotics, and low earth orbit satellites,” arguing for “strong long-term return on invested capital.”

What to Watch

The debate now centers on payoff timing. The bears argue that if AI revenue doesn’t scale quickly enough, operating margins compress and Alphabet stock and Amazon stock both face derating. Meanwhile, dip buyers counter that these are mega-cap, highly profitable franchises with durable cash flows, and one session of selling doesn’t redefine the longer-term arc.

Even with today’s drop, Alphabet shares are up 10% year to date (YTD), though Amazon shares are only up 1% YTD. Investors can watch for whether the lows hold into the close and whether a potential Gemini Pro release before month-end (61% odds) shifts the narrative on Alphabet stock.
