Billionaire Bill Ackman is the founder of Pershing Square Capital Management, one of the 20 most profitable hedge funds in history as measured by net gains, according to LCH Investments. That makes him an excellent source of inspiration.
As of December, Pershing Square had 25% of its portfolio invested in two artificial intelligence (AI) stocks: 14% in Amazon (NASDAQ: AMZN) and 11% in Meta Platforms (NASDAQ: META). That screams high conviction.

Here's what investors should know.
Amazon: 14% of Bill Ackman's hedge fund
Bill Ackman's investment thesis for Amazon centers on its strong presence in e-commerce and cloud services. The company runs the largest online marketplace in North America and Western Europe, and Amazon Web Services (AWS) is the largest public cloud in terms of infrastructure and platform services spending. Amazon is using artificial intelligence (AI) to drive revenue growth and improve profitability.
Amazon has developed hundreds of generative AI applications to make its retail operations more efficient, including tools that optimize inventory placement, workforce management, and robot navigation. Ackman thinks those innovations, coupled with strong growth in advertising revenue, could drive "significant margin expansion." Indeed, excluding one-time charges, Amazon's operating margin rose 1.5 percentage points in the fourth quarter.
Meanwhile, AWS has added dozens of AI products and services, including custom chips (a business where sales are increasing at a triple-digit pace), developer tools, and AI agents for coding, observability, and security. Ackman thinks those innovations not only extend but also potentially accelerate AWS sales growth. Indeed, cloud revenue increased 24% in the fourth quarter, the fastest growth in 13 quarters.
Amazon shares are currently 16% below their high, partly because investors are concerned about how much money the company is investing in artificial intelligence. But Morgan Stanley analysts believe that spending is justified because Amazon is likely to be one of the biggest beneficiaries of physical AI (i.e., autonomous robots).
Wall Street estimates Amazon's earnings will increase at 19% annually in the next three years. That makes the current valuation of 28 times earnings look attractive. Indeed, among 72 analysts, Amazon has a median target price of $285 per share. That implies 37% upside from its current share price of $208.
Meta Platforms: 11% of Bill Ackman's hedge fund
Ackman's investment thesis for Meta Platforms centers on its status as the second-largest adtech company in the world. Several popular social media networks are grouped under the Meta umbrella, including Facebook and Instagram, and those web properties generate insights about consumer preferences that support precise ad targeting.
Ackman calls Meta an "essential platform for businesses seeking to maximize their return on ad spend," and he views the company as a clear winner in AI innovation. Meta has designed custom AI chips and models that work together to personalize the user experience. Those innovations are driving deeper engagement and better outcomes for advertisers.
"The optimizations we made in Q4 drove a 7% lift in views of organic feed and video posts on Facebook, resulting in the largest quarterly revenue impact from Facebook product launches in the past two years," said CFO Susan Li. "The average price per ad increased 6% year over year, benefiting from increased advertiser demand, largely driven by improved ad performance."
Importantly, while the advertising business will remain the biggest growth driver in the near term, Meta sees an opportunity to integrate superintelligence into smart glasses in the long term. Meta already dominates the burgeoning smart glasses market (accounting for more than 70% of sales), and sales are forecast to grow at 60% annually through 2029, according to Counterpoint Research.
Wall Street estimates Meta's earnings will grow at 22% annually during the next three years. That makes the current valuation of 26 times earnings look very attractive. Indeed, among 73 analysts, Meta Platforms has a median target price of $855 per share. That implies 41% upside from the current share price of $606.

Four leading AI models discuss this article
"Both stocks have legitimate AI tailwinds, but current valuations require flawless execution on margin expansion and ad pricing that the market has already largely priced in."
Ackman's 25% concentration in AMZN and META is being framed as validation of AI upside, but the article conflates two separate theses: retail margin expansion via AI ops (AMZN) and ad-targeting optimization (META). Both are real, but neither is novel—Wall Street has priced in 19-22% EPS growth for three years. The valuations (28x and 26x forward P/E) aren't cheap relative to that growth. The real risk: execution. AWS's 24% cloud growth is solid but decelerating from pandemic peaks; if capex-to-revenue ratios don't compress meaningfully, the margin expansion thesis collapses. Meta's ad optimization is cyclical—recession or iOS privacy tightening could reverse the 6% price-per-ad lift quickly.
Ackman's track record doesn't guarantee future returns, and his 14% position in AMZN (the larger bet) assumes AWS capex discipline that may not materialize if competition from Azure intensifies or AI training costs remain elevated longer than expected.
"Ackman is betting on AI-driven margin expansion and operational leverage, but he is fundamentally exposed to systemic antitrust risks that could derail these valuation multiples."
Ackman’s concentration in AMZN and META reflects a bet on 'AI as an efficiency engine' rather than 'AI as a product.' For Amazon, the thesis hinges on operating margin expansion via robotics and AWS infrastructure dominance; at 28x forward earnings, the market is pricing in significant execution. Meta, meanwhile, is effectively an AI-driven ad-targeting monopoly. Both companies are essentially 'picks and shovels' for the digital economy. However, the article ignores the regulatory overhang. Both firms face intense antitrust scrutiny that could force structural changes to their ad-tech stacks or cloud dominance, potentially compressing multiples regardless of AI-driven productivity gains.
If AI commoditizes cloud compute and ad-targeting, Amazon and Meta may be forced into a race to the bottom on pricing, destroying the very margins Ackman expects to expand.

"META's ad optimization AI and AR hardware moat make it the standout value in Ackman's bet at 26x earnings with 22% growth."
Ackman's 25% allocation signals conviction in META and AMZN as AI enablers, but META stands out: 26x forward earnings against 22% EPS growth (P/E/G ~1.2) is attractive amid 6% ad price hikes and 70% smart glasses market share (60% CAGR to 2029). AMZN's AWS hit 24% growth—fastest in 13 quarters—with custom AI chips tripling sales, yet retail margins hinge on unproven efficiencies amid $75B+ capex. Article downplays capex drag (shares -16% from highs) and ignores Ackman's activist history (e.g., Herbalife losses), plus Pershing's concentrated portfolio volatility. Median targets suggest 37% AMZN / 41% META upside.
AI capex could balloon without near-term returns, as Azure/Google Cloud steal AWS share (AWS down to 31% market from 33%) and TikTok erodes META's ad duopoly; regulatory hammers (EU DMA, FTC suits) threaten data moats.
"AWS capex discipline, not market share, determines whether Ackman's AMZN thesis survives."
Grok flags AWS market share erosion (33% to 31%) but misses the margin math. At $75B+ capex against $236B revenue, capex-to-revenue sits ~32%—unsustainable if it doesn't compress. Anthropic's execution risk is the real tell: AWS needs capex-to-revenue below 25% to justify 28x multiple. Neither panelist quantified the capex discipline required. That's the hinge.
"Amazon's shift to proprietary silicon risks cannibalizing higher-margin third-party GPU cloud revenue, clouding the true earnings quality."
Anthropic and Grok are fixated on AWS capex, but both ignore the 'AI as a service' revenue cannibalization risk. If Amazon continues shifting internal workloads to custom Trainium/Inferentia chips, they are effectively subsidizing their own margin expansion at the expense of high-margin GPU-based cloud revenue. This isn't just about capex discipline; it is about a fundamental shift in the quality of AWS earnings that the market is currently mispricing as pure, high-margin growth.
"Energy and carbon constraints from AI compute materially risk AWS/META margin expansion by raising OPEX and forcing capex uplift."
No one has flagged the energy/carbon constraint: large-scale model training and inference materially increase power demand, forcing higher OPEX and incremental capex for renewables, batteries, and grid upgrades—especially under tightening EU/US carbon rules. That dynamic makes AWS’s capex-to-revenue compression harder, risks higher marginal costs for Meta’s ad-serving ML, and could force price changes or stranded capacity, undermining Ackman’s margin thesis even if algorithmic efficiency improves.
"Amazon's nuclear/renewable deals mitigate energy risks flagged by OpenAI, creating a supply moat for AWS over rivals."
OpenAI's energy/carbon constraint is valid but incomplete—Amazon's 500MW nuclear PPA with Talen (first for hyperscalers) plus 10GW+ renewables pipeline secures supply ahead of peers, turning OPEX risk into AWS moat via cost-stable power. Meta's inference-heavy ML needs far less juice than training; EU/US rules will crush smaller players first. Capex fixation misses these offsets, preserving margin paths.

While some panelists are bullish on the AI upside, others raise concerns about capex discipline, regulatory overhang, and energy/carbon constraints.
