Google’s Q4 earnings report is imminent! Its $4.1 trillion market capitalization faces a test, with performance growth needed to support valuation expansion.

Alphabet will release its quarterly earnings after the market closes on Wednesday, with the tech giant facing a critical test at a historic peak in market capitalization. After adding more than $2 trillion in market value over the past eight months, Alphabet’s total market cap has reached $4.1 trillion, just one step away from surpassing Nvidia to become the world’s most valuable company. The market is widely watching to see if its earnings growth can match its valuation multiple, which is at its highest level in 18 years. According to Bloomberg data, Alphabet is expected to see revenue growth of 17% and earnings per share growth of 23%. Bank of America is even more optimistic, predicting both revenue and EPS will exceed market consensus, mainly thanks to the stability of the advertising market and accelerated growth in search and YouTube driven by the Gemini 3.0 model. After last year’s concern that Alphabet was falling behind in the AI race, the company is rebuilding market confidence in its leadership through its AI models, self-developed chips, and cloud business. However, the surge in capital expenditure will be a key focus for investors. Following Meta Platforms’ sharp increase in spending, Bank of America raised its forecast for Alphabet’s 2026 capital expenditure to $139 billion, significantly above the market consensus of $119 billion. Investors will closely watch whether Alphabet will follow in Microsoft’s footsteps—being sold off due to slowing cloud growth and heavy AI spending—or follow Meta’s path, justifying high investment with strong revenue guidance. As last year’s leader among the “Magnificent Seven” in US stocks, Alphabet’s continued stock rally has put it at a high level. Tim Ghriskey, senior portfolio strategist at Ingalls & Snyder, noted that due to the sustained strength in the share price, even with strong earnings performance, there is a risk of profit-taking as the market “prices in all good news”; investors now expect exceptionally high earnings thresholds to sustain further price gains. Valuation at 18-Year High, Performance Must Be Perfect Alphabet’s share price has risen more than 65% in the past year and continued its climb into early 2026, up another 8.5%. All this has pushed it to a historic valuation peak: its current P/E ratio is about 28 times expected earnings, not only well above the 10-year average of 21 times, but also the highest since early 2008. This high valuation means very little margin for error. Less than a year ago, investors were concerned that startups like OpenAI would erode Google’s search moat. Now, with the iteration of the Gemini model and the expansion of the TPU (Tensor Processing Unit) semiconductor business, market sentiment has reversed. Daniel Flax, Senior Research Analyst at Neuberger Berman, believes that compared to the past, Alphabet now has broader growth drivers, especially with cloud business poised for massive growth and strong free cash flow in the next two to three years. Core Business Strong, Revenue and EPS Likely to Beat Expectations According to previous Wallstreetcn articles, Bank of America’s analysis shows Alphabet’s core business is on an accelerated track. Analysts have raised their fourth-quarter revenue forecast to $95.9 billion and EPS forecast to $2.65, both above Wall Street consensus. Specifically, search business revenue is expected to grow 15% year-on-year to $61.9 billion, mainly benefiting from accelerated usage after the Gemini 3.0 launch and increased ad conversion rates from AI tools like Performance Max. YouTube ad revenue is expected to rise 15% year-on-year to $12 billion, showing robust spending on performance ads. Cloud business is projected to maintain a high growth rate of 35%, with revenue reaching $16.2 billion. Channel research indicates Google’s momentum in ad innovation is sufficient to offset potential traffic pressure from new AI search formats. Capital Expenditure to Rise Significantly, Intensity of AI Investment in Focus As AI infrastructure construction heats up, spending guidance has become a critical variable affecting the share price. Bloomberg data shows the market initially expected Alphabet’s 2026 capital expenditure to rise about 28% to $117 billion. But Bank of America notes that, referencing Meta’s recent large upward guidance, Alphabet may offer annual guidance close to $140 billion during the earnings call. Such intense investment is a double-edged sword. Last week, Microsoft suffered a historic selloff due to slowing cloud growth combined with heavy AI investment; in contrast, Meta saw its share price surge as strong income prospects justified its spending. Tim Ghriskey believes Alphabet is more like Meta: as long as new products emerge and growth stays high, investors confidently overlook aggressive spending plans. Bank of America also points out that despite the increased intensity in capital expenditure, Alphabet’s capital allocation efficiency remains superior to peers thanks to its TPU system. Improved Operating Efficiency, Automated Driving Valuation Surges Beyond core advertising and cloud businesses, Alphabet’s other segments have also reported positive developments. Its autonomous driving unit Waymo recently raised $16 billion at a valuation of $126 billion, nearly tripling its valuation from $45 billion in October 2024. On cost control, although depreciation expense is expected to rise 49% year-on-year, overall operating costs are well managed. Bank of America forecasts fourth-quarter operating margin to increase by 119 basis points year-on-year to 39.1%. Excluding depreciation and amortization, the cost base is expected to increase only by 5.3% year-on-year, with hiring data showing the company continues to enforce strict cost control. In addition, the fair value revaluation of stakes in SpaceX and Anthropic could bring one-off gains to quarterly results.
