Mega-cap results will test whether record AI capex is paying off after a sharp chip selloff.

Spreadex and CNBC reported that Alphabet and Microsoft (Oct 28) and Amazon (Oct 29) headline the week, with investors scrutinizing whether cloud growth justifies 2026 capital-spending guides running into the hundreds of billions; chip names rebounded Monday premarket after the prior week's rout.

Investors weigh whether soaring AI capital spending can be justified before the cloud revenue shows up.

Yahoo Finance framed the week's Big Tech reports as a referendum on AI spending, noting that Alphabet, Microsoft and Amazon are guiding to sharply higher capital expenditure and that markets want evidence the outlays translate into durable cloud and AI revenue.

The public filing opens Anthropic's books at the top of the AI financing race.

Yahoo Finance and Dealroom reported Anthropic's Oct. 26 S-1 disclosing $16.3B first-half revenue (up from $4.6B for all of 2025) and an $80.7B net loss driven largely by fair-value changes on convertible bonds, with the lab planning to list as 'ANT' and citing up to ~$750B in compute commitments.

Skeptical coverage questions whether trillion-dollar AI valuations can hold against enormous losses.

IBTimes and The Next Web highlighted the $80.7B loss and the reported ~$1.5T-$2T listing target, noting investor pushback that the valuation sits above what comparable AI stocks already fetch and that the filing did not set a share count or price range.
