## Summary

Alphabet lost just over $500bn in market value after investors reacted to signs that its AI push is putting pressure on established business lines. The sharp fall followed results showing that Google’s AI summaries are affecting the number of adverts it can sell alongside search results, its main source of revenue.

Revenue rose 25% year on year to $127.6bn, while Google Cloud revenue more than doubled to almost $31bn. But quarterly profit fell 25%, and Alphabet reported negative free cash flow of more than $9bn, as heavy AI investment drove spending above incoming cash. Its market value fell from $3.97tn to $3.46tn, and its shares dropped nearly 13%.
