Billionaire Bill Ackman Has 56% of His Hedge Fund's $16.5 Billion Portfolio Invested in 3 Outstanding Stocks

Pershing Square's public-equity exposure is concentrated in three names — Alphabet (22.6% of marketable equities), Brookfield Corp. (17.7%) and Uber Technologies (15.5%) — which Bill Ackman views as undervalued growth compounds. Alphabet is benefiting from AI-led monetization with Google Cloud revenue up 34% YoY and Search accelerating to 15% growth in Q3 2025, has integrated Gemini into products and signed a revenue-generating Gemini deal with Apple, and trades at a forward P/E ~30. Brookfield saw net carried interest rise to $154m in Q3 from $61m a year earlier, expects ~$25bn of net carried interest over the next decade and rapid Wealth Solutions growth (management targets assets doubling in five years and 15% ROE), trading near ~24x trailing distributable earnings. Uber is scaling demand aggregation with monthly active users +17% in Q3, trips per user +4% and 33% adjusted EBITDA growth recently, with enterprise value around 22x trailing adjusted EBITDA.

Analysis

Market structure: Ackman’s public positioning (GOOGL 22.6%, BN 17.7%, UBER 15.5%) spotlights beneficiaries: cloud/AI platform owners (GOOGL) and diversified asset managers/insurance (BN) capture outsized cash flows; demand is shifting from commoditized compute to integrated AI stacks (TPUs + Gemini) which tightens Google’s pricing power versus smaller cloud players. Uber’s role as a demand-aggregator for mobility makes it a likely intermediary beneficiary from autonomous vehicle rollouts, preserving take-rates even if vehicle ownership falls. Cross-asset: stronger AI-driven revenue growth supports equity risk premium compression vs. government bonds; positive tech earnings expectations likely flatten short-dated IV in options but steepen longer-dated term premia; higher insurance asset bases at BN link to credit spreads and rate curves.

Risk assessment: Key tail risks include aggressive antitrust/regulatory action on Google’s search/Apple deal (1-2 year horizon), a fundraising/market-return shock that delays Brookfield’s carried interest realization (12–36 months), and faster-than-expected AV adoption that commoditizes Uber’s margins (3–5 years). Short-term (0–3 months) volatility drivers: quarterly earnings, Apple Siri Gemini rollout timing, and Fed rate guidance which can reprice growth multiples >10% intraday. Hidden dependencies: BN’s earnings rely on private-fund mark-to-market and IRR waterfall timing; GOOGL’s margin upside depends on TPU adoption rates and enterprise contract cadence.

Trade implications: Implement a 2–3% long position in GOOGL now via 9–12 month 1.5x delta LEAP calls or 24/30 call spreads (roll if price rises >20%); set add-on if forward P/E drops below 25. Establish a 2–3% core long in BN (NYSE: BN) using stock or bullish 12-month call spreads, trim to 1% if distributable earnings multiple compresses to >30x or if carried-interest guidance falls >20%. For UBER, sell 45–60 day 1.5–2.0% OTM put spreads for a 1–2% notional allocation to collect premium, or buy a small (1%) calendar call spread into next two earnings to play accelerating MAUs.

Contrarian angles: Consensus underweights Google’s enterprise edge (TPUs + Gemini) — if Apple search deal rolls out at scale in next 6–12 months, incremental revenue could beat by $3–6B annual run-rate; this is likely underpriced at current 30x forward P/E. Conversely, Brookfield’s thesis is contingent on sustained private markets performance; a 10–15% drawdown in private valuations or a 100–150bp sustained rise in yields would defer ~$5–10B of expected carry and justify trimming. Historical parallel: active managers capturing carry after market troughs can multiyear re-rating; if those catalysts miss, valuation reversion is swift, so use explicit stop-loss thresholds (GOOGL -15%, BN -20%).

Key Decisions for Investors

• Establish a 2–3% portfolio long position in Alphabet (GOOGL/GOOG) via 9–12 month LEAP calls (or 24/30 call spreads) to capture AI/cloud monetization; add another 1% if forward P/E falls below 25 or Q2 cloud revenue growth drops <20%.
• Initiate a 2–3% long position in Brookfield Corp. (BN) using stock or 12-month call spreads; set a trim/stop if trailing distributable earnings multiple expands above 30x or management revises 10-year carried interest below $20B.
• Put on a tactical, income-oriented 1–2% position in Uber (UBER) by selling 45–60 day put spreads 5–10% OTM (defined risk) to harvest premium while betting on trip/MAU growth; alternatively buy a small calendar call spread into the next two earnings if you want convex upside exposure.
• Relative/hedge trade: go long GOOGL (2%) vs short NVDA (1%) via options (buy GOOGL calls, buy NVDA puts or sell calls) to express conviction in software/IP-led AI monetization versus pure-play hardware valuation risk; limit NVDA short to 50% notional of the GOOGL long and close if NVDA falls >25% or GOOGL rises >30%.
• Monitor three explicit catalysts over next 90 days — Apple Gemini/Siri rollout dates, BN fund-launch cadence and quarterly carried-interest realization, and next Google Cloud/Google Search quarterly results — and adjust positions if any miss consensus by >15% (revenues or carry guidance).
