Alphabet (GOOGL) Pushes Deeper Into AI Following Gemini 4 As Valuation Debate Builds

Simply Wall St·09/28/2026 02:22:24
Listen to the news

Alphabet (GOOGL) has pushed deeper into AI this month, lining up the Gemini 4 model, an early Project Suncatcher satellite launch, and a fresh Experian integration inside Gemini’s consumer finance experience.

Alphabet’s recent AI announcements land against a backdrop of mixed near term trading and powerful longer term wealth creation. The share price is up 9.1% year to date and the stock’s 1 year total shareholder return of 39.9% and 3 year total shareholder return of about 2.7x suggest the bigger trend has been strong, even as the 90 day share price return declined 2.8% while investors weigh fresh AI spending, regulatory fines and new partnerships, such as Experian’s Gemini integration, against those gains.

Alphabet now appears to be caught between fresh AI bets and a share price that has already moved significantly. Do you lean into the current valuation, or sit tight and wait for a cheaper entry point?

Most Popular Narrative: 70% Overvalued

Alphabet last closed at $343.92, while the most followed narrative pegs fair value at $202.62, which points to a wide gap between enthusiasm in the market and the underlying valuation work that has been done according to tripledub.

The arithmetic of waiting, which is where this gets uncomfortable. Suppose the middle road is roughly right and you buy today anyway. What do you actually collect? On the middle road the shares are worth $272.54 in three years, $313.86 in five, and $395.49 in ten. Against $356.13 today, that is down about twenty four percent, down about twelve percent, and finally up about eleven percent. Read the last column again. Eleven percent in total after a decade. Call it one percent a year, for owning what may well be the best business of this generation, through ten years of headlines and lawsuits and product cycles.

See why 232 investors see Alphabet as 70% overvalued.

Result: Fair Value of $202.62 (OVERVALUED)

Still, this narrative could crack if Alphabet's heavy AI capital spending earns weaker returns than expected, or if regulatory penalties materially reshape its dominant search and ads model.

Another View on Alphabet’s Valuation

Tripledub’s fair value work frames Alphabet as roughly 70% overvalued at $343.92, yet the SWS DCF model comes out in a very different place. On that methodology, the stock trades about 29.1% below an estimated future cash flow value of $485.36, which points to upside instead of downside risk.

The gap between those two approaches raises a practical question for you. Which feels more realistic: a cautious narrative that leans on demanding return assumptions, or a cash flow model that says the current price already bakes in a margin of safety, at least on those inputs?

Look into how the SWS DCF model arrives at its fair value.
