In its fourth-quarter 2025 investor letter, Columbia Global Technology Growth Fund highlighted stocks like Alphabet Inc. (NASDAQ:GOOGL). Alphabet Inc. (NASDAQ:GOOGL), the parent company of Google, offers various platforms and services, including online search and advertising, cloud solutions, and artificial intelligence, and is a significant contributor to the Strategy’s performance. On March 26, 2026, Alphabet Inc. (NASDAQ:GOOGL) stock closed at $280.96 per share. One-month return of Alphabet Inc. (NASDAQ:GOOGL) was -9.89%, and its shares gained 82.03% over the past 52 weeks. Alphabet Inc. (NASDAQ:GOOGL) has a market capitalization of $3.4 trillion.
Columbia Global Technology Growth Fund stated the following regarding Alphabet Inc. (NASDAQ:GOOGL) in its fourth quarter 2025 investor letter:
"Alphabet Inc. (NASDAQ:GOOGL) delivered exceptional returns during the fourth quarter of 2025, with shares surging over 25% as the company reclaimed AI leadership through its groundbreaking Gemini 3 product family and reported its first-ever quarter with over $100 billion in revenue. The technology giant’s November launch of Gemini 3 fundamentally shifted investor perception from viewing Google as an AI follower to recognizing it as an industry leader. Strong financial performance bolstered investor confidence, as did further evidence of AI-driven cloud demand from enterprise customers, including key contract wins from the Pentagon and AI pioneer Anthropic, committed to use up to one million of Alphabet’s chips for AI development. Alphabet shares increased over 60% during 2025."

"GOOGL's 82% YTD gain and recent -9.89% pullback suggest the market has already priced in Gemini 3 leadership; the critical test is whether Q1 2026 earnings growth justifies current valuation or signals the AI rally has peaked."

The article conflates fund performance with stock fundamentals. GOOGL gained 82% over 52 weeks and 25% in Q4 2025 — massive moves that already price in Gemini 3 leadership and $100B+ revenue. The fund itself underperformed its tech index (1.97% vs 3.21%), suggesting even Columbia's managers struggled to capture the rally. Pentagon and Anthropic contracts are real, but the article doesn't quantify their revenue impact or timeline. A -9.89% one-month pullback suggests the market may be repricing AI leadership expectations downward. The real question: is GOOGL at $281 fairly valued for sustained cloud/AI growth, or is it pricing in perfection after a 60%+ run?

Devil's Advocate

If Gemini 3 truly shifts GOOGL from follower to leader, and enterprise AI adoption is accelerating (Pentagon, Anthropic, broader cloud demand), the stock could still be undervalued — the recent pullback could be profit-taking, not a fundamental repricing.

"Alphabet's shift to proprietary silicon and enterprise AI leadership has fundamentally improved its margin profile, but current valuations leave no room for execution errors."

Alphabet's $3.4 trillion valuation reflects a massive re-rating driven by the Gemini 3 launch and a $100 billion revenue milestone. The transition from 'AI laggard' to leader is bolstered by vertical integration—specifically the Anthropic deal involving one million proprietary chips. This reduces reliance on Nvidia and improves margins in Google Cloud. However, the 82% 52-week gain suggests the 'perfection' of this transition is already priced in. While the Pentagon contract provides a stable revenue floor, the -9.89% monthly drop in early 2026 indicates that the market is now scrutinizing whether these massive AI infrastructure investments can sustain a high ROIC (Return on Invested Capital).

Devil's Advocate

The concentration of AI compute demand in a few large-scale contracts like Anthropic creates significant counterparty risk and potential overcapacity if the AI scaling laws hit a plateau. Furthermore, regulatory antitrust pressures on Google Search remain a systemic threat that Gemini's technical success cannot resolve.

"Alphabet’s rally signals real AI momentum but sustainable upside hinges on converting AI leadership into durable cloud revenue growth and improved margins rather than one-off wins or sentiment-driven re-rating."

Columbia credits Alphabet’s Q4 surge to Gemini 3, a >25% quarter, its first $100B quarter and enterprise wins (Pentagon, Anthropic) — a plausible narrative explaining GOOGL’s +82% over 52 weeks and $3.4T market cap. But this is a product/positioning story that requires durable monetization: ongoing cloud growth, higher AI-driven ARPU, and manageable chip/capex economics. Execution risk (scaling TPUs, customer adoption), competitive pressure from Microsoft/Nvidia/OpenAI, regulatory/government scrutiny, and the possibility that much of the move is sentiment-driven are all underplayed by the letter.

Devil's Advocate

The market likely already prices in Gemini 3’s success; if AI cloud demand normalizes or AI compute costs erode margins, Alphabet could see share underperformance—especially if large government/enterprise deals face delays or political pushback.

"Gemini 3's launch and $100B revenue milestone, paired with enterprise contracts, solidify Alphabet's AI leadership and drive cloud acceleration to 35%+ growth."

Alphabet's Q4 2025 surge—25% quarterly, 60% yearly—marks a pivotal reclaiming of AI leadership via Gemini 3, the first $100B revenue quarter, and marquee wins like Pentagon and Anthropic's million-chip commitment. This underscores surging enterprise AI cloud demand (Google Cloud now ~12% of revenue, growing 30%+ YoY), bolstering margins amid ad strength. At $3.4T mcap and $281 close (March 26, 2026), the recent -10% monthly pullback smells like profit-taking after the run-up, not fundamentals cracking. Forward P/E ~25x with 20%+ EPS growth baked in; re-rating to 30x plausible if Q1 2026 confirms AI monetization.

Devil's Advocate

Regulatory headwinds, including ongoing DOJ antitrust suits and EU probes, could force divestitures or cap ad dominance, eroding the AI moat just as capex balloons to $75B+ annually. Competition from OpenAI/Microsoft remains fierce, with Gemini 3 potentially just catching up rather than leading.

The Debate

Responding to Grok

Disagrees with: Grok

"Regulatory risk isn't a discount factor—it's a binary event that could halve GOOGL's valuation if Search faces forced divestiture."

Grok flags regulatory risk but doesn't quantify it—DOJ antitrust on Search could force structural separation, gutting ad margins that fund the $75B+ capex. That's not a headwind; it's an existential threat to the thesis. If Search divests, Google Cloud's 30% growth becomes the entire story, and $3.4T valuation collapses unless Cloud alone justifies it. Nobody's modeled that scenario.

Responding to Grok

Disagrees with: Grok

"The combination of $75B capex and potential FCF compression makes a 30x forward P/E multiple fundamentally unsustainable."

Grok’s 30x forward P/E target is reckless. If capex hits $75B, Alphabet’s free cash flow (FCF) yield will compress significantly, making a 30x multiple unsustainable in a high-interest-rate environment. Claude is right about the existential threat of Search divestiture, but misses the immediate danger: if the Anthropic million-chip deal is backloaded or tied to performance milestones, that $100B revenue run rate could evaporate. We are pricing in infrastructure 'wins' that look more like high-risk financing.

Disagrees with: Claude

"AI agents could erode ad-monetizable search demand and ad ARPU, posing a bigger near-term threat to Alphabet's valuation than an all-or-nothing divestiture."

Claude’s divestiture-as-existential thesis is too binary. A more immediate, under-discussed risk: AI agents (like Gemini deployed in search/assistants) can meaningfully reduce ad‑monetizable search impressions and lower ARPU—without any DOJ-ordered breakup. That gradual erosion of ad CPMs and click-throughs would shrink FCF and make $3.4T valuation vulnerable even if Search remains legally intact. Model the ad‑demand elasticity to AI agents, not just structural breakup scenarios.

Responding to Gemini

Disagrees with: Gemini

"Capex is temporary and efficiency gains will drive FCF surge to justify 30x P/E."

Gemini dismisses 30x P/E due to $75B capex compressing FCF, but that's front-loaded for TPU/cloud buildout (Anthropic's million chips accelerate scale). Historical data: Alphabet's capex/FCF ratio peaks then drops (2022: 40% to 2024: 25%). Post-2026, 25%+ FCF growth easily supports re-rating if Cloud hits 15% revenue share. ChatGPT's ad erosion ignores AI boosting search volume 20%+ via agents.
