Alphabet stock rises as AI users and ad revenue grow

Alphabet Inc. Class C (US02079K1079) is trading on a new mix of scale and scrutiny after AI products reached 2.5 billion monthly users and second-quarter ad revenue hit $81 billion. The shares last changed hands at $344.82, after a 1.22% move in the session covered by the latest market snapshot.

On August 21, 2026, a market report said Alphabet's second-quarter earnings per share were $9.11, far above the $2.89 consensus estimate, while revenue reached $119.80 billion versus $117.07 billion expected. The same report put the net margin at 54.77% and return on equity at 51.32%, numbers that underline how profitable the core business still is even as capital spending stays elevated.

What the numbers say

Market data from August 20, 2026 showed the Class C shares closing at $338.20 on volume of 14,165,362, leaving the stock well below the $346.20 intraday high seen in the later snapshot. The gap matters because the latest price still sits close enough to that range to keep traders focused on the stock's recent volatility rather than a one-way trend.

Consensus stays firm at $20.51 in earnings per share for the current fiscal year, and one market overview said Alphabet has raised 2026 capital expenditure guidance to $195 billion-$205 billion from $180 billion-$190 billion. That combination leaves investors comparing earnings strength with a spending plan that is still expanding.

AI scale and spending

AI usage is now a direct part of the investment case. The 2.5 billion monthly-user figure gives Alphabet a distribution advantage that few peers can match, while the $81 billion of second-quarter ad revenue shows how the core search and video businesses continue to fund the build-out.

The market is also weighing a larger capital budget against those profits. A higher capex range of $195 billion-$205 billion implies heavier spending on data centers, chips, and model infrastructure through the rest of 2026.

Product reach

Google Search, YouTube, and Google Cloud remain the key products behind the numbers. Search and YouTube keep monetizing audience scale, while Cloud is still the clearest operating bridge between AI infrastructure and reported revenue growth.

Price context

Alphabet Class C shares last traded at $344.82, with the recent snapshot showing a session high of $346.20. The stock also closed at $338.20 on August 20, 2026, giving investors two reference points for where momentum is settling.
