Billionaire Brad Gerstner Dumped All of His Alphabet Then Bought 2 Stocks Nobody Expected

📉 Altimeter Capital fully exited its 519,290-share Alphabet position in Q1 2026, selling the entire stake.

🚀 Gerstner opened a new $259.5 million position in Arm Holdings (ARM) consisting of 1,715,440 shares.

🛡️ A second new position was established in Axon Enterprise (AXON), valued at approximately $63.3 million.

💰 Alphabet's high valuation and massive $175-$185 billion capital expenditure guidance are cited as reasons for the exit.

📈 Arm Holdings delivered $1.49 billion in Q4 2026 revenue, a 20% year-over-year increase.

🤝 Major tech giants including Google, NVIDIA, Microsoft, and OpenAI are building on Arm's new AGI CPU platform.

🔭 The addressable market for Arm's data center CPU architecture is projected to reach over $100 billion by 2030.

📊 Axon Enterprise raised full-year revenue growth guidance to between 30% and 32%.

📉 Axon stock has declined 41% over the past year, making Gerstner's purchase a contrarian move.

⚠️ Arm Holdings currently trades at 156x forward earnings, significantly above analyst consensus targets.

⚖️ Axon Enterprise trades at 60x forward earnings but carries risks related to internal control weaknesses and high stock-based compensation.

🧠 The investment thesis shifts from scaled incumbents with rich valuations to emerging verticals and infrastructure enablers.

Bullish Signals
  • Arm Holdings is a pure-play beneficiary of the AI buildout, with major partners like Google, Meta, NVIDIA, Microsoft, and OpenAI committing to its architecture.
  • Arm reported strong financial performance in fiscal Q4 2026 with $1.49 billion in revenue and data center royalty revenue more than doubling year-over-year.
  • CEO Rene Haas confirmed over $2 billion in customer demand for the new Arm AGI CPU across fiscal 2027 and 2028.
  • Axon Enterprise demonstrated robust growth with Q1 2026 revenue up 34% to $807.35 million and ARR reaching $1.49 billion.
  • Management at Axon raised full-year guidance to 30-32% revenue growth, indicating confidence in their physical public-safety infrastructure strategy.
  • Gerstner's move aligns with a strategic rotation into 'picks-and-shovels' AI infrastructure providers and niche vertical operators with strong moats.
Risk Factors
  • Alphabet is trading at a high 27 trailing P/E ratio following a 100% one-year run, suggesting potential valuation concerns.
  • Alphabet's 2026 capital expenditure guidance of $175-$185 billion is reshaping the free-cash-flow profile in a way that may deter some investors.
  • Arm Holdings trades at an elevated 156x forward earnings, well above the analyst consensus target price of $254.87 against a current price around $383.
  • Axon Enterprise faces material weaknesses in internal controls which could pose operational or compliance risks.
  • Axon is projected to incur significant stock-based compensation costs of $590-$620 million in 2026, impacting net income.
  • Following Gerstner's trades directly involves accepting triple-digit P/E ratios and the potential for 25% weekly drawdowns.
Full Analysis
Altimeter Capital, managed by billionaire Brad Gerstner, completely exited its position in Alphabet (GOOGL) during Q1 2026, selling all 519,290 shares. The firm simultaneously established two new positions: 1,715,440 shares of Arm Holdings (ARM) valued at approximately $259.5 million and 148,986 shares of Axon Enterprise (AXON) worth about $63.3 million. This move places Gerstner alongside other prominent investors like Stanley Druckenmiller and Bill Ackman who have also reduced or sold their Alphabet holdings in the same quarter. The article analyzes the rationale behind these trades, suggesting a strategic rotation from a high-valuation mega-cap with massive capital expenditure guidance into 'picks-and-shovels' AI infrastructure and niche vertical operators. Gerstner is moving away from Alphabet's 27 trailing P/E ratio and $175-$185 billion capex outlook toward Arm Holdings, which serves as a pure-play on the architecture powering the AI buildout funded by companies like Google and Meta. Arm Holdings reported fiscal Q4 2026 revenue of $1.49 billion, up 20% year-over-year, with data center royalties more than doubling. CEO Rene Haas highlighted over $2 billion in customer demand for the new Arm AGI CPU across fiscal 2027 and 2028, supported by major partners including Google, NVIDIA, Microsoft, and OpenAI. The addressable market for this architecture is projected to exceed $100 billion by 2030. Axon Enterprise represents a contrarian entry into physical public-safety infrastructure, combining hardware like Tasers and drones with cloud software. Q1 2026 revenue grew 34% year-over-year to $807.35 million, with Annual Recurring Revenue reaching $1.49 billion. Management raised full-year guidance to 30-32% revenue growth despite the stock falling 41% over the past year, presenting a potential value opportunity for investors willing to accept higher valuation multiples.
