Chipotle Mexican Grill (NYSE: CMG) and Meta Platforms (NASDAQ: META | META Price Prediction) became the centerpiece of Bill Ackman’s boldest portfolio moves. Pershing Square exited its entire Chipotle stake and rotated into Meta, betting AI infrastructure will outperform struggling fast-casual dining. Should everyday investors follow his lead?
Why Ackman Walked Away From Chipotle
Chipotle’s Q4 2025 results revealed operational strain that likely accelerated Ackman’s exit. Comparable sales dropped 2.5%, driven by a 3.2% decline in transactions, which was only partially offset by a 0.7% increase in the average check. This marked the first same-store sales decline in over two decades. Operating margin compressed to 14.1% from 14.6% year-over-year, while food costs climbed to 30.2% and labor held at 25.5%.
The stock’s performance reflects this pressure. CMG has fallen 37.44% over the past year and sits 3.14% lower year-to-date. Despite opening 132 restaurants in Q4 with 97 Chipotlanes, expansion hasn’t offset weakening consumer demand. Bureau of Economic Analysis data shows food services spending grew just 3.9% from January through November 2025, lagging the 4.6% increase in total personal consumption expenditures.
Insider activity reinforces caution. Curtis Garner, Chief Strategy and Technology Officer, sold over 468,000 shares throughout 2025, including 100,000 shares at $36.05 in mid-December. CEO Scott Boatwright parted with 81,759 shares at $42.91 in August. When executives sell aggressively as the stock declines, it signals limited near-term confidence.
Meta’s AI Infrastructure Bet Looks Different
Meta’s Q4 2025 results delivered the growth story Ackman appears to be chasing. Revenue hit $59.89 billion, beating estimates of $59.76 billion, with earnings per share reaching $8.88 versus the $8.39 consensus. Revenue climbed 24% year-over-year, driven by an 18% increase in ad impressions and 6% higher ad pricing. Net income of $22.77 billion reflected 9.3% growth despite heavy AI spending.
Meta plans $115 billion to $135 billion in capex for AI infrastructure, a bet CEO Mark Zuckerberg frames around building “personal superintelligence.” Operating margin of 41% demonstrates profitability even as R&D expenses surged 30.7% to $51.37 billion in fiscal 2025. Meta returned $26.26 billion to shareholders through buybacks in 2025.
Valuation supports the rotation. Meta trades at 28x trailing earnings with a forward P/E of 22x, reflecting expected earnings acceleration. Chipotle’s 33x trailing P/E looks expensive given 4% quarterly earnings growth and 4.9% revenue growth. Meta’s 30.1% net margin dwarfs Chipotle’s 12.9%, and analysts see Meta reaching $860, compared to its current price near $650.
What Ackman’s Move Signals About Both Companies
Ackman’s exit from Chipotle reflects concerns that the transaction decline and margin pressure represent structural challenges rather than temporary headwinds. The company’s plan to open 350 to 370 restaurants in 2026 addresses expansion but doesn’t resolve the underlying demand weakness that drove the first same-store sales decline in over two decades. The rotation suggests Ackman views operational recovery stories as less compelling than secular growth opportunities in the current market environment.
The shift into Meta signals conviction that AI infrastructure investment will generate returns that justify near-term margin pressure. Meta’s advertising business continues to show resilience with 24% revenue growth, while the $115 billion to $135 billion capex commitment positions the company for long-term AI monetization. Ackman’s timing reflects a view that AI-driven tech returns will define the next market cycle, making Meta’s 1.28 beta and heavy spending acceptable trade-offs for investors focused on growth over stability. The move highlights a broader portfolio shift from consumer discretionary exposure to digital infrastructure plays.
