# Alphabet Stock After Q3 2026 Earnings: Google's Search Slowdown Is Mostly the Calendar — InvestMoat Research

_Google Search revenue grew 12% in Q3 2026, down from 17%, and Alphabet fell about 10% after hours. Measured against two years ago, Search grew nearly as fast as it did a year earlier. Last year's comparison and a currency swing explain most of the drop, which leaves about a point for AI Mode and two smaller effects._

## Summary

Alphabet's Search & other revenue grew 12% year over year in Q3 2026, after 17% in Q2, and Alphabet's chief business officer said lower monetization in AI Mode was one of the reasons. Measured over two years, which strips out the easy and hard comparisons of 2025, Search grew 28.3%, against 28.5% in Q3 2025 and 30.4% in Q2 2026. The CFO put the drag from lapping last year's acceleration at about 3 points, and Alphabet's own constant-currency figures show a currency swing of about a point between Q2 and Q3, so AI Mode, the EU's de minimis change and a World Cup timing shift share about one point between them. Microsoft, reporting the same night, shows what the next step looks like when AI is priced in: Microsoft 365 commercial cloud revenue grew 17% on 5% seat growth. My read is that Google's search moat came through Q3 with a small, real cost from AI Mode, and the two-year growth rate over the next two quarters will show whether that cost stays small as ads in AI Mode go international.

## What would prove this wrong

If Google Search & other two-year stacked growth (reported revenue against the same quarter two years earlier) falls below 27% in Q4 2026 (about 8.8% year over year, allowing for the currency headwind Alphabet has guided) or below 30% in Q1 2027 (about 9.1% year over year), read from the releases due in early February and late April 2027, then the slowdown is more than the calendar and currency, AI Mode is costing Google more than a point, and I'm wrong.

_Status as of October 29, 2026: **holding**._

Google Search & other, Q3 2026: +12% · Search growth over two years: +28.3% · Diluted EPS, Q3 2026: $2.12 · GOOGL price: (live)

The worst number in Alphabet's Q3 was Search, which slowed to 12% growth from 17%. Management also said AI Mode earns less than classic search. Together with a profit miss and no let-up in spending, it sent the stock [down about 10% after hours](https://www.investing.com/news/transcripts/earnings-call-transcript-alphabet-q3-2026-profit-miss-sparks-10-afterhours-drop-93CH-4981037) on October 28. **I think Search slowed far less than 12% suggests. Measured against two years ago, it grew nearly as fast as it did a year earlier.**

**Google Search & other revenue growth, against one year earlier and against two years earlier, on reported revenue. The one-year rate fell five points in Q3. The two-year rate, which looks through 2025's slow start and fast finish, is back near where it was in Q3 2025, though it has eased for three quarters. This is the series the falsifiable claim tracks.**

Why two years? Google Search had an odd 2025. It grew 10% in Q1 2025 and 12% in Q2. In the second half it sped up to 15%, then 17%. So the first half of 2026 was compared against easy quarters and looked great, and the second half is compared against hard ones. Comparing each quarter with the same quarter two years back cancels most of that out. One caveat: these are reported numbers. Currency helped a year ago and didn't this quarter, so on a constant-currency basis the two-year rate is roughly a point lower than in Q3 2025. That's the same point I come back to below.

## Where the five points went

Alphabet's managers gave their own list on the call. Chief Business Officer Philipp Schindler called currency "the single largest driver" of the change from Q2. CFO Anat Ashkenazi said Q3 began lapping the search acceleration of late 2025, and expects "a couple of points" of the same lapping in Q4. My estimate of the sizes: the comparison is worth close to 3 points, since Search went from 11.7% growth in Q2 2025 to 14.5% in Q3 2025. Currency is worth about a point, judging by Alphabet's total revenue, which grew 24% in Q2 with a point of help from currency and 25% in Q3 with none. That's roughly 4 of the 5 points.

The last point or so is shared by three things Schindler listed. Some Asian retailers cut ad spending after the EU ended its de minimis exemption for low-value imports. Media advertisers had pulled budgets into June for a World Cup with more matches than July. And AI Mode, Google's chatbot-style search tab, is growing fast and "had an impact because of the lower monetization we were seeing in AI mode."

That admission is real, and it's the part a moat investor should care about. But Schindler also said "the majority of AI mode queries are incremental," and Sundar Pichai said overall query growth is the highest in five years. A query that wasn't being asked before, earning less than average, pulls the average down without taking revenue away. It costs Google growth rate, not dollars. On Q3's numbers, that cost fits inside one point.

## What Microsoft shows about the next step

**Microsoft 365 commercial cloud revenue growth against commercial seat growth, by calendar quarter (fiscal Q1 FY26 is the September 2025 quarter). Revenue keeps growing about ten points faster than seats, because each seat is paying more.**

| Period | Microsoft 365 commercial cloud revenue | Microsoft 365 commercial seats (incl. GitHub) |
| --- | --- | --- |
| Q3 2025 | 18% | 7% |
| Q4 2025 | 17% | 7% |
| Q1 2026 | 20% | 6% |
| Q2 2026 | 16% | 7% |
| Q3 2026 | 17% | 5% |

_Figures as of Fiscal Q1 FY27, quarter ended September 30, 2026.

Microsoft reported the same evening and shows what AI looks like once it's priced. Its seats grew 5%, the slowest in five quarters, which CFO Amy Hood partly put down to "weaker sales execution". Revenue from them still grew 17%. She said revenue per seat growth "was led by our premium seat-based offerings, including M365 Copilot, E5 and E7", the higher-priced Office plans. The AI is sold on top of the seat, so it raises the price.

Google hasn't reached that step. Ads in AI Mode run in the US and are only now going to other countries, along with ads that appear partway through a back-and-forth conversation. Schindler said click-through rates on sponsored product listings in AI Mode are already similar to organic ones. If that holds as the ads scale, AI Mode's yield climbs toward classic search, and the one-point drag shrinks. If the yield stalls while AI Mode's share of queries grows, the drag compounds.

## The miss and the money

The other two reasons for the drop are real, but neither is about Search. Diluted earnings per share were $2.12 against about $3.02 that analysts expected, [per Investing.com](https://www.investing.com/news/transcripts/earnings-call-transcript-alphabet-q3-2026-profit-miss-sparks-10-afterhours-drop-93CH-4981037). Losses on equity stakes, which swing with the market value of what Alphabet owns, cut $0.55 of that. Add it back and earnings still missed, by roughly 12%, so the miss isn't only an accounting mark. Operating income still rose 30%. The spending plan wasn't news either: the 2026 range of $195–205B is the one Alphabet gave in July, and it still says 2027 will be "significantly" higher.

**How Alphabet is paying for the build, by quarter, in billions of dollars. Free cash flow went negative in Q2 2026 and buybacks stopped at the start of the year. Borrowing and, since June, new stock have taken their place. Alphabet sold no stock before its June 2026 offering.**

| Period | Free cash flow | Buybacks | Net new debt | New stock sold |
| --- | --- | --- | --- | --- |
| Q3 2025 | 24.5$B | 11.5$B | -1.1$B | 0$B |
| Q4 2025 | 24.6$B | 5.5$B | 20.2$B | 0$B |
| Q1 2026 | 10.1$B | 0$B | 29.9$B | 0$B |

Shareholders are being diluted to pay for the build, and that's a fair reason to want a lower price. It just wasn't new on October 28: the June offering set it up, and this quarter added $12.4B through Alphabet's program for selling shares gradually on the market. What changes the value of the search franchise is whether its revenue keeps up as AI Mode grows. That's the variable I'd watch.

The live blocks below put Google next to the other ad and seat tolls in coverage. Each row is a business where AI either raises or lowers what the company earns per unit it already sells: a seat, an ad, a search.

## The case that AI Mode is a bigger problem than a point

The strongest version goes like this. Pichai said query growth is the best in five years. If queries grew anywhere near 12%, then revenue per query barely grew at all, and that happened in a quarter when AI Mode is still a minority of searches. Every quarter AI Mode takes a bigger share, the average falls further. The two-year rate looks steady only because 2025's strong second half is in it, and Alphabet itself has warned of more comparison pressure and a bigger currency headwind in Q4.

There's support in the rest of the print, too. The chart's own two-year line has eased for three quarters running. YouTube ads slowed to 9% growth from 13% in Q2. And Meta, which faced the same currency, World Cup and Asian retailers, [held up far better](/research/meta-q3-and-the-price-per-ad-crossover). Its impressions and price per ad imply ad growth of roughly 25% in Q3, from about 28% in Q2. A three-point slowdown at Meta next to a five-point one at Google Search is what a bear would point to as Google-specific.

I take that seriously. Alphabet gives no query growth figure, so revenue per query can't be measured from outside. I don't have a full answer to Meta. Its own comparison got harder too, so the gap may mean Google is ceding a little ad growth to it, which is exactly what my thresholds would catch. What I can measure is the two-year rate, and it says Search is growing nearly as fast as it did a year ago, with about a point unexplained. If the two-year rate holds through Q1 2027 while AI Mode ads scale abroad, the drag is staying small. If it breaks below my thresholds, the bear case is right.

Where does that leave the moat? The framework rates Google's learned interfaces strong, and my reading of Q3 is that it backs that: queries are growing at their fastest in five years, so people are asking Google more, in a new format. Query growth alone can't prove nobody is asking elsewhere too, but it isn't what a habit breaking looks like. Amazon's ads inside its own store face the same question once shoppers ask its assistant instead of scrolling results.

> **The question I'd ask of any AI toll** — Ask whether AI raises or lowers what the company earns on each unit it already sells. Microsoft's seats are earning more. Google's searches are earning a little less on the new format, and the two-year growth rate is the cleanest place to see how much.

## The two prints that decide it

1. Early February 2027, Alphabet's Q4: the two-year rate against Q4 2024. Above 27%, after the currency headwind Alphabet has guided, means the calendar story holds. Below that, AI Mode is costing more than I think.
2. The same call: any figure on ads in AI Mode outside the US, or on how AI Mode's earnings per query compare with classic search.
3. Late April 2027, Alphabet's Q1: the second reading, against a weak Q1 2025, so the bar is higher at 30%.
4. Microsoft's fiscal Q2 in late January 2027: Microsoft 365 revenue growth staying well ahead of seat growth keeps the contrast intact.

For a holder, Q3 doesn't look like the quarter Google's search franchise broke. It looks like a good quarter measured against a hard one, with a small new cost that Google named itself. I'd judge the stock on whether that cost stays small, and the two-year Search rate will say so within two prints.
