GOOGL vs MBLY: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
GOOGL is the larger of the two ($4.17T market cap): the incumbent the market prices for continued execution (22.29x forward earnings, beta 1.21). MBLY is the smaller challenger ($6.14B), cheaper on forward earnings (14.84x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
GOOGL vs MBLY: the tie-breaker metrics
Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | GOOGL | MBLY | What it tells you |
|---|---|---|---|
| Market cap | $4.17T | $6.14B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 22.29 | 14.84 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 1.21 | 1.24 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 59% of range | 9% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 6.69 | 0.74 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: MBLY is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how GOOGL and MBLY affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. GOOGL and MBLY share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined GOOGL and MBLY exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Alphabet (GOOGL) do?
Alphabet is the parent company of Google and is one of the most diversified technology businesses in the world. Search advertising (Google.com search results) remains the single largest revenue contributor and one of the highest-margin businesses ever built. YouTube is the second-largest advertising property online and the largest video platform globally. Google Cloud Platform (GCP) is the third-largest hyperscale cloud after AWS and Azure and has finally turned operating profitable in 2024.
What does Mobileye Global (MBLY) do?
Mobileye Global designs the vision chips (its EyeQ system-on-chip family) and software that power advanced driver-assistance systems in cars from roughly 27 automaker brands worldwide. Its core business ships EyeQ silicon and camera-based ADAS features (lane keeping, automatic emergency braking, adaptive cruise) to original equipment manufacturers, and it is layering on higher-value products such as its SuperVision and Chauffeur hands-off systems and imaging radar. The company was acquired by Intel in 2017, taken public again in a 2022 IPO, and Intel remains the majority shareholder while gradually selling down its stake.
GOOGL vs MBLY: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- GOOGL drivers: Defending Search against AI disruption; Gemini and the model race.
- MBLY drivers: Core ADAS volume recovery; Premium products moving up the stack.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Antitrust pressure remains intense (the US DOJ Search case ruling, plus EU and Indian regulatory actions). For MBLY, mobileye faces intensifying competition from Nvidia, Qualcomm, and Chinese chip players like Horizon Robotics and Huawei, some of whom are winning share in China where Mobileye has struggled.
GOOGL or MBLY: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick GOOGL if you believe its drivers more; MBLY if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the GOOGL and MBLY guides.
GOOGL vs MBLY: the full fundamentals
GOOGL. Alphabet's trailing P/E of about 17x looks low only because 2026 GAAP earnings include very large non-operating gains; on 2027 consensus EPS of about $15.06 the stock trades near 23x, and at about 9.5x sales it is no longer the discount name it was in early 2026. The shares are up about 37% over the past year but have been roughly flat for three months, as the market weighs 24% revenue growth against capital spending that has squeezed free cash flow.
MBLY. Mobileye is profitable on an adjusted basis but reports large GAAP net losses, so headline GAAP EPS (about -$4.97 trailing) looks far worse than the roughly $0.49 of forward adjusted EPS analysts model. At about $7.29 a share, the ~$6.2 billion market cap is near 3 times trailing sales and roughly 15 times forward earnings, and it mostly values the legacy ADAS business, leaving the autonomy and robotaxi roadmap as optionality. Third-quarter results on October 29, 2026 carry a consensus of about $0.10 of adjusted EPS on roughly $477 million of revenue.
Headline figures (approximate, October 2026): GOOGL shows revenue (ttm) ~$446 billion (up ~24% year over year in Q2 2026), margins (ttm) ~61% gross, ~34% operating, net income (ttm) ~$244 billion, inflated by non-operating gains, eps ~$19.93 trailing GAAP; ~$20.59 2026 and ~$15.06 2027 consensus; MBLY shows revenue (ttm) ~$2.02B (+0.4% YoY latest quarter), revenue (q2 2026) ~$508M, adjusted eps (q2 2026) ~$0.19 vs ~$0.06 est., gaap net income (ttm) ~-$4.06B.
The bottom line: GOOGL vs MBLY
GOOGL and MBLY are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined GOOGL and MBLY exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between GOOGL and MBLY?
+
Alphabet is the parent company of Google and is one of the most diversified technology businesses in the world. Mobileye Global designs the vision chips (its EyeQ system-on-chip family) and software that power advanced driver-assistance systems in cars from roughly 27 automaker brands worldwide. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is GOOGL or MBLY the better stock?
+
Neither is universally better. GOOGL is the larger incumbent; MBLY is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, GOOGL or MBLY?
+
On forward P/E (as of October 2026), GOOGL trades at 22.29x and MBLY at 14.84x, so MBLY is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both GOOGL and MBLY?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of GOOGL vs MBLY?
+
GOOGL: Antitrust pressure remains intense (the US DOJ Search case ruling, plus EU and Indian regulatory actions). AI is genuinely disruptive to the core Search business, and Google's defense playbook is unproven. Capital spending on AI infrastructure has compressed free cash flow to about $22.7 billion over the trailing twelve months, so returns depend on that capacity being used profitably. Reported earnings in 2026 include large non-operating gains, so trailing EPS of about $19.93 overstates the recurring run rate, and analysts expect 2027 EPS to be lower than 2026. MBLY: Mobileye faces intensifying competition from Nvidia, Qualcomm, and Chinese chip players like Horizon Robotics and Huawei, some of whom are winning share in China where Mobileye has struggled. Revenue is tied to cyclical global auto production and to customer inventory swings, which have historically produced sharp guidance cuts. GAAP results remain deeply loss-making (a trailing net loss of about $4.1 billion, including a roughly $3.8 billion loss in Q1 2026), tied largely to accounting for the intangible assets from the Intel deal, so profitability depends on adjusted metrics. Intel's continued sell-down of its majority stake creates a persistent supply overhang on the shares. The robotaxi ambition is unproven, cash-intensive, and years from meaningful revenue, so the autonomy thesis carries execution and timing risk. The share price itself has become a risk to sentiment: down about 19% over three months and near its 52-week low, while Deutsche Bank trimmed its target to $12 from $13 in October.
