Alphabet Inc (GOOGL)

Alphabet has one of the widest moats in existence and one of the clearest threats to it, which is why the shares trade the way they do. This page covers both, plus the quirk that means you own it twice in most index funds.

The business

Search advertising still produces most of the profit. Google Cloud is the growth engine and is now large enough to matter. YouTube is a second advertising business that would be a significant company on its own. Everything else — Waymo, the research divisions — consumes cash and is largely optionality rather than value in any model.

The moat

Search is a habit reinforced by defaults, and defaults are bought. That is both the strength and the fragility: the moat depends partly on distribution agreements that are under regulatory challenge. The live question is whether AI-generated answers cannibalise the advertising model or simply change its format. Assess it by watching search revenue growth rather than by reading opinions about AI — if the moat is breaking, it shows there first.

What to check before you value it

• Search revenue growth — The single most important number. If AI is damaging the business, this is where it appears before anywhere else.
• Cloud margin, not just growth — Google Cloud reached profitability later than its rivals. The margin trend tells you whether it is a real business or bought share.
• Regulatory exposure — Default search placement payments and ad-tech structure are both under challenge in several jurisdictions.
• Capital returns — Alphabet began paying a dividend in 2024 alongside large buybacks, which changed how the market classifies it.

How much of it you already own

Alphabet appears twice in most index funds because of its dual share classes, and the two together are roughly 6.1% of the Vanguard S&P 500 UCITS ETF as at July 2026 (class A around 3.4%, class C around 2.7%). See what is inside an ETF.

Recent filings

Search growing 12.5% with AI Overviews already deployed was the direct answer to the cannibalisation worry, at least for that quarter. The first dividend in company history, alongside a $70bn buyback, signalled that Alphabet now considers itself a capital-returning business rather than a pure growth one.

How Oak Growth scores it

Oak Growth runs Alphabet through the same four pillars as every other company it covers — moat, management, economics and value — and publishes a discounted cash flow intrinsic value alongside the margin of safety against the current price. Because those figures move with the market and with each set of results, they live in the app rather than on this page. See the 4-pillar method →

Common questions

Is Alphabet Inc undervalued?

That depends on the price on the day you ask. Oak Growth publishes a discounted cash flow intrinsic value for Alphabet Inc and the resulting margin of safety, updated from live market data rather than a fixed figure. The checks that decide it are set out on this page.

Does Alphabet Inc have an economic moat?

Yes, though it is the most actively contested moat among the large technology companies. Search benefits from habit, scale and paid default placements, and the open question is whether AI-generated answers change the advertising format or erode it.

Is GOOGL in index funds and ETFs?

Yes, and twice over. Alphabet's class A and class C shares are held as separate line items by index funds, and combined they were roughly 6.1% of the Vanguard S&P 500 UCITS ETF as at July 2026.

How do you value Alphabet Inc?

Model Search, YouTube and Cloud separately, and treat the research divisions as optionality rather than value. The key input is the Search revenue growth rate, because that is where any AI disruption would appear first.
