Amazon's AI Chip Breakthrough and OpenAI Partnership: A GARP Opportunity in a Cooling AI Sector?

The artificial intelligence (AI) sector, once a paragon of unbridled optimism, is now at a crossroads. While 2025 has seen a record $1.4 trillion in AI-related spending commitments from firms like OpenAI, concerns about speculative overinvestment and valuation dislocation are mounting. Amid this backdrop, Amazon's recent AI chip advancements and its potential $10 billion partnership with OpenAI have sparked debate: Is this a growth-at-a-reasonable-price (GARP) opportunity, or a speculative bet in a sector primed for correction?

Strategic Momentum: Custom Silicon and OpenAI's Bet on AWS

Amazon's AI infrastructure strategy has long centered on custom silicon. The company's Trainium and Inferentia chips, developed since 2015 and 2018 respectively, now claim 30–40% better price performance than NVIDIA's equivalents. The launch of Trainium3 in late 2025 and a $38 billion multi-year compute contract with OpenAI underscore Amazon's ambition to dominate AI workloads. This partnership, if finalized, would not only diversify OpenAI's compute providers but also validate Amazon's silicon in high-stakes generative AI applications.

The strategic implications are profound. OpenAI's decision to reduce reliance on Microsoft-its longtime partner signals a shift in the AI ecosystem's power dynamics. For Amazon, the deal could accelerate adoption of Trainium chips, which are already being deployed in data centers at scale. Analysts note that AWS's 29% share of the global cloud infrastructure market positions it to capitalize on the $500 billion AI infrastructure boom, with custom ASICs offering a cost edge over NVIDIA's GPUs.

Valuation Dislocation: Undervalued Growth or Overbuilt Potential?

Amazon's valuation appears to reflect a disconnect between its AI-driven growth and current stock price. The company trades at a forward P/E of 34.7x below its peer group average of 40x but above the broader industry's 19.9x. A discounted cash flow (DCF) analysis suggests the stock is undervalued by 15.6% at current levels, a premium to traditional metrics but reasonable given AWS's 20.2% year-over-year revenue growth in Q3 2025.

However, the AI chip division's contribution to Amazon's valuation remains opaque. While AWS accounts for 60–70% of the company's operating profits, Amazon does not break out AI-specific revenue. Capital expenditures on AI infrastructure, however, reveal a long-term commitment: $100 billion in 2025 alone, including a $31.4 billion outlay in Q2. This spending, while diluting free cash flow (FCF) to $14.8 billion in Q3 2025, signals confidence in AI's future.

The question of valuation dislocation hinges on whether these investments translate to sustainable margins. AWS's high-margin cloud services and advertising revenue provide a buffer, but the AI chip market is fiercely competitive. NVIDIA retains 70–95% market share, and Google's Ironwood TPUs are emerging as credible alternatives. Amazon's 150% quarter-over-quarter revenue growth for Trainium2 chips is promising, but scaling to 1 million units by 2025 will require execution.

Competitive Positioning: Navigating a Crowded Semiconductor Landscape

Amazon's AI chip ambitions face headwinds from entrenched rivals. NVIDIA's CUDA ecosystem and dominance in training workloads remain unmatched, while Google's vertical integration of TPUs with its Gemini model offers a compelling full-stack proposition. Yet Amazon's strengths lie in its cloud infrastructure and strategic partnerships. The OpenAI deal, if consummated, could provide real-world performance data for Trainium chips, while AWS's 29% cloud market share ensures a steady pipeline of enterprise AI demand.

Market reactions to the OpenAI partnership have been mixed. While some analysts view it as a validation of Amazon's silicon, others question whether the $10 billion investment is more symbolic than substantive, given OpenAI's cash constraints. Amazon's stock has not surged post-announcement, with investors citing fatigue from circular AI dealmaking. Yet the company's $125 billion capex for AI and cloud infrastructure in 2025 suggests a long-term play, not a short-term gimmick.

Sector Trends: Cooling or Consolidation?

The AI sector shows no signs of cooling in Q3 2025. Enterprise demand for AI is driving tech spending, with AI-related investments growing 14% year-over-year. Alphabet's £5 billion UK AI push and NVIDIA's "super-cycle" narrative indicate sustained momentum. However, caution persists. OpenAI's $1.4 trillion spending plan and Alphabet's $3.5 trillion market cap raise questions about overbuilding and speculative excess.

For Amazon, the key is balancing growth with prudence. Its AI chip division benefits from the sector's tailwinds but must avoid the pitfalls of overinvestment. The company's DCF-derived fair value of $294.27 per share implies a 15.6% upside, a premium that may be justified if AWS's AI workloads continue to scale. Yet the risk of a sector-wide correction looms, particularly if AI adoption fails to meet expectations.

Conclusion: A GARP Opportunity with Caveats

Amazon's AI chip breakthrough and OpenAI partnership present a compelling GARP opportunity. The company's undervalued stock (34.7x forward P/E) aligns with AWS's high-margin growth and AI infrastructure investments. Strategic momentum, including the potential $10 billion OpenAI deal and Trainium3's deployment, positions Amazon to capture a larger share of the AI semiconductor market.

However, risks abound. NVIDIA's dominance, Google's TPUs, and sector-wide concerns about overinvestment could temper growth. Investors must weigh Amazon's long-term AI bets against the possibility of a correction. For those with a multi-year horizon, the current valuation offers a reasonable entry point-but only if the company executes on its ambitious roadmap.
