Forward Price-to-Earnings (P/E)
As of mid-October 2026, Alphabet trades at a Forward P/E ratio of approximately 22.37x, based on a stock price of ~$336.91 and forward consensus estimates (GuruFocus).
Trailing twelve-month (TTM) P/E ratios appear artificially cheap (around 16.9x) because the TTM earnings ($19.90 per share) are heavily inflated by the aforementioned $99 billion unrealized equity gain recorded in Q2. When normalizing for this non-operating gain, the Forward P/E of 22.37x provides a much more accurate reflection of the market's pricing of Alphabet's core earnings power.
Enterprise Value to EBITDA (EV/EBITDA)
Given the heavy distortion in net income from equity holdings, and the massive scale of debt recently added to the balance sheet, EV/EBITDA serves as a superior valuation metric because it captures the true cost of Alphabet’s newly leveraged capital structure.
Alphabet's Enterprise Value (EV) stands at approximately $4.1 to $4.2 trillion, accounting for its $4.15 trillion market capitalization, $100+ billion in debt, and $126 billion in cash. Trailing EV/EBITDA: Alphabet trades at roughly 22.7x to 23.5x TTM EBITDA (StockRow, ValueInvesting). Forward EV/EBITDA: When factoring in Evercore's aggressive forward estimates for cloud and TPU revenue expansion, the forward EV/EBITDA multiple compresses to approximately 12.5x (GuruFocus).
A historical perspective reveals that Alphabet's EV/EBITDA multiple has ranged from 10.8x to 29.6x over the past decade. The current trailing multiple of 22.7x places it in the 88th percentile of its 10-year historical range, indicating that the market is already pricing in a significant portion of the anticipated AI revenue growth.
However, Evercore’s $450 price target is anchored on 25x its 2028 GAAP earnings estimate and 14x its 2028 EBITDA estimate. If Alphabet successfully scales external TPU sales to $113 billion by 2028 as projected, the stock is currently undervalued relative to its future cash generation capabilities.
Risks, Red Flags, and Open Questions
While the hardware pivot offers a compelling growth narrative, Alphabet faces a gauntlet of existential regulatory risks, structural market shifts, and immense capital allocation gambles.
1. Antitrust and Regulatory Overhang
Alphabet remains embroiled in multiple, high-stakes antitrust battles globally, though recent developments have offered a mix of relief and ongoing friction.
The Ad-Tech Ruling: On September 2, 2026, U.S. District Judge Leonie Brinkema issued a ruling in the Department of Justice’s antitrust lawsuit targeting Google's digital advertising monopoly. In a massive win for Alphabet, the judge explicitly rejected the DOJ's structural remedies, which sought to force Google to divest AdX and its publisher ad servers. Instead, the court accepted behavioral remedies (the specifics of which remain sealed) (Motley Fool). This ensures that Google's core ad-network, which generated $81.6 billion in Q2, remains intact to fund the AI capex cycle. Search Default Ruling Fall-out: In a separate case in 2025, Judge Amit Mehta barred Google from entering exclusive distribution agreements to remain the default search engine on browsers like Apple's Safari. The long-term impact on mobile search query volumes remains a significant unknown. * Google Play Store Settlement: In mid-October 2026, a federal judge rejected an $85 million fee request from consumer lawyers involved in a $630 million settlement over Google Play Store billing practices, demanding clearer accounting. While a minor procedural hurdle, the underlying $700 million total settlement highlights the persistent erosion of Google's absolute control over its app ecosystem margins (PYMNTS).
2. Search Cannibalization via AI Overviews
Perhaps the most critical operational risk is the threat generative AI poses to the traditional search advertising model. The global rollout of "AI Overviews" and "AI Mode" directly answers user queries on the search results page, fundamentally reducing the necessity for users to click on publisher links—and, by extension, the ads that surround them.
While Q2 2026 Search & other advertising revenue grew 17% year-over-year to $63.3 billion, this represented a deceleration in growth for the first time in six quarters. Analysts warn of a tougher Q3 comparison as the cannibalization effect potentially matures (Digital Applied).
Furthermore, publishers are revolting. Subsequent to rulings by the UK Competition and Markets Authority (CMA), Google was forced to implement a global "publisher opt-out" in August 2026, allowing publishers to exclude their content from AI training and overviews without losing search indexing visibility. In September 2026, a federal judge dismissed antitrust suits from publishers claiming AI Overviews destroyed their traffic, stating that while the 58% drops in click-through rates are real, they are issues for Congress, not antitrust law (TechTimes). If major publishers systematically opt out of Google's AI ecosystem, the quality of Gemini and AI Overviews could rapidly degrade.
3. The ROI on Historical Capex
The final red flag is the sheer scale of capital Alphabet has committed to AI infrastructure. With $707 billion in contractual purchase commitments and an ongoing capex run-rate exceeding $200 billion annually, Alphabet is making a historically unprecedented bet.
The open question for equity analysts is the ultimate Return on Invested Capital (ROIC—a metric used to assess a company's efficiency at allocating capital to profitable investments). If enterprise demand for TPUs and Gemini Enterprise subscriptions plateaus, or if open-source models commoditize AI inference faster than Google can recoup its hardware costs, the resulting depreciation expenses and FCF deficits will permanently impair the company's valuation multiples.
Conclusion: Alphabet is no longer simply a search engine; it is a leveraged, capital-intensive infrastructure provider attempting to corner the global AI compute market. While Evercore's $75 billion TPU sales estimate provides a credible path to $450 per share, investors must accept the volatile reality of negative free cash flow, escalating debt, and persistent antitrust litigation as the necessary cost of maintaining market supremacy.
