Incredible demand for artificial intelligence (AI) compute has driven sales at some of the biggest chipmakers to new heights. Nvidia has been one of the biggest beneficiaries of demand for compute, as its GPUs offer unparalleled computing power. Advanced Micro Devices is also seeing strong demand for its competing GPUs. Meanwhile, Broadcom has emerged as a key partner for several hyperscalers designing their own chips for AI training and inference.
But the biggest winner in AI semiconductors won't be any of those massive chipmakers. It's the company with both the technology and the scale to support the growing semiconductor industry. Here's why Taiwan Semiconductor Manufacturing (NYSE: TSM) will emerge as the biggest winner of all among the semiconductor stocks.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »
After years of incredible growth for Nvidia and AMD, there's cause for concern about the future of their businesses and the place of their chips in hyperscale data centers. Some of the biggest concerns regarding hyperscale build-outs are the costs. Capital constraints are becoming a meaningful factor in some buying decisions for these companies, as they grow increasingly reliant on debt to fuel their continued build-outs.
While GPUs will always have a place in AI data centers, a growing portion of chips are custom silicon. Amazon said the majority of its new chip purchases will be its own Trainium chips this year. CEO Andy Jassy said using Trainium chips saves the company tens of billions of dollars in capital expenditures each year. Likewise, Alphabet is using more and more of its own chips, TPUs, and it has started selling TPUs to select third parties.
To that end, investors may think the biggest winners will be the chipmakers hyperscalers partner with to design custom AI accelerators. Google's TPUs are built on top of Broadcom's IP. But those designs tend to be more fickle. Google is reportedly in talks with Marvell Technology for new TPU designs. Marvell once held the design for Amazon's Trainium chips, but the third and fourth generations of the chip design went to AIChip.
But regardless of who designs the chips for training and running artificial intelligence in hyperscale data centers, they all rely on TSMC to print and package those chips. That's a constant, unlikely to change, given TSMC's significant technological lead and massive scale.
TSMC is the world's largest contract chip manufacturer. It accounted for 73% of all spending on third-party manufacturing in the first quarter of 2026, and that share has increased over the last few years as AI accelerators have fueled spending growth. AI chips require the most advanced manufacturing technology to achieve peak performance. That's where TSMC can separate itself from the competition.
Even as some competitors begin to make advances on TSMC's technology in certain edge cases, the Taiwanese company also benefits from its massive scale. Given the significant demand for AI chips, no other semiconductor manufacturer has the capacity to print and package chips at the required quality and speed. Even TSMC itself is facing capacity shortages. That's why management is spending another $60 billion to $64 billion in capital expenditures this year, up from $40.9 billion last year.
TSMC's scale also allows it to spend heavily on research and development to produce the next generation of technology. And with a roster of big-name clients, it can work closely with engineering teams to ensure it meets their forthcoming needs. As a result, it can maintain a significant technological lead by outspending the competition, even if R&D accounts for just 6% of total revenue.
That creates a virtuous cycle. TSMC wins big contracts, builds out more capacity, spends more on R&D, and wins new big contracts that only it has the capacity to serve. The strong demand from the AI boom has also enabled it to raise prices across its manufacturing services, resulting in very strong gross margins even as it ramps up new technology (which typically weighs on gross margins).
Despite the strong growth projected for the business, investors are only paying 24.5 times forward earnings expectations. Considering analysts are currently projecting earnings-per-share growth of 30% over the next two years, that's an incredible price to pay for the dominant business in the industry.

Four leading AI models discuss this article
"TSM's dominance in advanced node manufacturing provides a structural moat that allows it to capture AI-driven growth while offloading the design-cycle risks onto its customers."
TSM is the ultimate 'picks and shovels' play in the AI gold rush, effectively monopolizing the high-end node manufacturing (3nm/2nm) required for modern LLM training. At a 24.5x forward P/E, the valuation is remarkably compressed relative to its 30% EPS growth trajectory, especially when compared to the volatility of fabless designers like NVDA or AMD. The article correctly identifies the 'virtuous cycle' of scale and R&D, but the real alpha here is the pricing power; TSM is essentially a utility for the entire AI sector, allowing them to capture margin regardless of which specific chip architecture wins the hyperscaler wars.
The thesis ignores the extreme geopolitical risk of the Taiwan Strait, where any escalation could render TSM's physical assets stranded or destroyed, a 'black swan' event that no amount of R&D spending can mitigate.
"TSMC's moat is real, but the article conflates 'indispensable supplier' with 'best stock,' ignoring geopolitical tail risk and the possibility that 30% EPS growth is a peak, not a floor."
The article's core thesis—that TSMC wins regardless of who designs chips—is sound on capacity and technology moat. But the valuation math is deceptive. At 24.5x forward P/E with 30% EPS growth, TSMC trades at 0.82x PEG (price-to-earnings-growth), which looks cheap. However, that 30% growth assumes sustained capex of $60B+ annually and no geopolitical friction. The article omits: (1) Taiwan political risk is real and priced nowhere near adequately, (2) Samsung and Intel are closing the gap in advanced nodes faster than 2009, (3) TSMC's gross margins may compress if capacity glut emerges post-2027, and (4) the article was written in 2026—we're reading historical analysis, not current market conditions.
If custom silicon adoption accelerates faster than expected and hyperscalers vertically integrate manufacturing (as Amazon and Google clearly want to), TSMC's volume growth stalls even if margins hold—turning this into a 'slow compounder' rather than a 'biggest winner.'
"TSMC is best-positioned to benefit from AI-driven semiconductor demand, but the investment thesis hinges on a durable AI capex cycle and stable geopolitical conditions to justify its premium valuation."
While the article correctly highlights TSMC’s scale, pricing power, and its central role in AI silicon supply, it glosses over cycle risk and geopolitics. TSMC’s upside relies on a continued AI capex boom and its ability to fund roughly $60-64B of annual capacity expansion while preserving ROIC, which could compress if utilization softens or yields worsen at leading-edge nodes. The piece also omits rising competition from Samsung Foundry and Intel, plus the possibility that hyperscalers push more in-house fabrication or diversify to other foundries. Even with strong demand, valuation around 24-25x forward earnings could look rich if AI demand slows.
The moat could crack if hyperscalers accelerate in-house fabs or shift more volume to Samsung/Intel, eroding TSMC's pricing power. Additionally, Taiwan geopolitical risk could disrupt supply or force capex reallocation, creating volatility and margin pressure.
"TSMC's AI tailwinds are real but priced without sufficient discount for single-country geopolitical risk that no amount of capex can mitigate."
The article correctly identifies TSMC's foundry monopoly and pricing power as durable advantages in the AI buildout, with 73% share of third-party capacity and $60-64B capex this year reinforcing its lead. Yet it underplays execution risk: even at 24.5x forward earnings against 30% EPS growth, any delay in 2nm or CoWoS ramp could compress margins faster than peers. Hyperscalers' shift to custom silicon also fragments demand, and TSMC's reliance on a single geography creates binary exposure not captured in the valuation. Capacity shortages are real but self-inflicted if geopolitics force diversification.
A sudden U.S.-China crisis or invasion threat could render TSMC's Taiwan fabs inoperable overnight, making the 'virtuous cycle' thesis irrelevant regardless of current earnings momentum.
"The long-term threat to TSMC is not just geopolitical, but the strategic disintermediation of their manufacturing role by hyperscalers building custom silicon."
Claude, your point on custom silicon is the real sleeper risk. Hyperscalers like Google and Amazon aren't just buying chips; they are aggressively verticalizing their own TPU and Inferentia pipelines. If they successfully move to in-house packaging or alternative foundries, TSMC’s 'utility' status evaporates. We are over-indexing on current node dominance while ignoring the long-term threat of hyperscaler disintermediation, which would fundamentally break the pricing power thesis that Gemini and the others are relying on.
"Hyperscaler vertical integration increases TSMC's near-term volume demand even as it threatens long-term pricing power—the 24.5x multiple prices in neither scenario adequately."
Claude and Gemini both flag hyperscaler vertical integration as a threat, but they're conflating two different timelines. Google's TPU packaging and Amazon's Inferentia are real, but they still need TSMC for leading-edge logic nodes—they can't replicate 3nm/2nm in-house at scale. The disintermediation risk is real post-2030, not now. What nobody's flagged: TSMC's near-term moat is actually *strengthened* by custom silicon because hyperscalers need more total capacity, not less. The margin compression risk is real, but it's a 2028+ problem, not a 2026 valuation concern.
"Yield and margin risk at leading-edge nodes could erode TSMC's ROIC well before 2028, even as capacity expands, challenging the notion that the moat is safely strengthened now."
Claude's point about near-term moat being strengthened by custom silicon is plausible, but it understates execution and yield risk at 2nm/3nm. If yield ramps disappoint or hyperscalers slow their pace, ROIC could compress sooner than 2028, even with 'more capacity needed' from customers. The dynamic could flip into a 'price discipline' challenge for TSMC, raising the risk that a 24-25x multiple undercuts if AI capex cools or rivals gain tempo.
"Yield issues at 2nm could force earlier diversification away from TSMC, compressing margins before 2028."
Claude's dismissal of near-term disintermediation ignores that disappointing 2nm yields, as ChatGPT notes, would likely push hyperscalers toward Samsung or internal options by 2027 rather than 2030. This timeline compression turns the capacity glut risk into an immediate threat to the 24.5x multiple if Taiwan frictions escalate simultaneously.
TSMC's dominance in AI silicon supply and pricing power are durable advantages, but execution risk, geopolitical tensions, and potential disintermediation by hyperscalers pose significant threats to its current valuation.
