TSMC's 2027 Spending Forecast Hits $90 Billion as AI Demand Strains Chip Supply

A $90 Billion Forecast Puts Expansion in Focus

UBS estimates that Taiwan Semiconductor Manufacturing Company could spend $90 billion on factories and equipment in 2027, while Goldman Sachs forecasts $85 billion. Both figures exceed the market average of $75.3 billion, reflecting expectations that artificial intelligence demand and rising equipment costs will require a much larger investment budget.

TSMC's announced capital spending plan for 2026 is $60 billion to $64 billion. UBS's forecast for 2027 would be $26 billion above the upper end of that range, an increase of about 41%. Goldman Sachs's estimate would represent an increase of roughly 33%. Capital spending is money used to build and equip facilities that can produce chips for years, rather than money spent on everyday operations.

The forecasts put a price on a growing challenge: customers want more advanced processors, while manufacturing and packaging capacity remain tight. AI demand is spreading beyond the accelerators that perform large amounts of mathematical work to the central processing units, network chips and other components needed to run entire data centers.

TSMC has not announced actual capital spending amounts for 2027 through 2029. Its third quarter earnings briefing, scheduled for October 15, 2026, at 2 p.m., is the next opportunity for management to explain the direction of investment. CTBC Securities Investment Advisory researcher Chang Tun-hsiang expects the full outlook for 2027 to come in January, following the company's usual reporting pattern.

The central issue is how quickly investment can become usable capacity. More expensive machinery raises the budget even before a factory produces additional chips, and new manufacturing processes require years of preparation. Packaging capacity must also grow so that completed chips can become products ready for customers.

How the Banks' Spending Estimates Compare

UBS and Goldman Sachs sit toward the upper end of a broad range of forecasts. JPMorgan estimates capital spending of $86 billion in 2027, Bank of America projects $83 billion, Citi forecasts $81 billion, and Yuanta estimates $80 billion. Morgan Stanley expects $75 billion to $80 billion.

The $90 billion UBS forecast exceeds the $75.3 billion market average by $14.7 billion, or about 20%. Goldman Sachs's $85 billion estimate is $9.7 billion higher, or about 13%. These gaps show how much more investment the most optimistic banks expect than the wider market currently assumes.

For 2026, Goldman Sachs forecasts spending of $64 billion and UBS estimates $63 billion, compared with a market average of $61.3 billion. Those estimates remain within TSMC's announced range. Chang considers another increase to that range unlikely at the coming briefing, although spending could move toward its upper limit.

Analyst Hsieh Chen-yen, in commentary first published on October 12, estimated $70 billion to $80 billion for 2027 and $90 billion to $100 billion for 2028. JPMorgan also forecasts $100 billion in 2028, while Citi estimates $90 billion. Goldman Sachs's revised forecast puts both 2027 and 2028 at $85 billion; another forecast attributed to the bank puts 2028 at $98 billion. The expectations for a larger investment cycle are widespread, but the annual amounts vary substantially.

Demand and Equipment Prices Drive the Budget Higher

TSMC raised its 2026 spending plan from an initial $52 billion to $56 billion to $60 billion to $64 billion at its July earnings briefing. Both ends of the range increased by $8 billion. Chairman and chief executive C.C. Wei attributed the revision mainly to growing customer demand, with equipment price inflation also contributing.

Wei said the company's spending over the coming three years would exceed the preceding three years by an even greater amount than it had previously anticipated. He also described AI demand as stronger than TSMC had expected and said it could remain strong through 2029 or 2030, while allowing for fluctuations along the way.

TSMC's July guidance called for revenue measured in US dollars to rise slightly more than 40% in 2026. That growth outlook helps explain its willingness to invest, although higher equipment prices mean each dollar of spending may buy less production capacity than before.

Why AI Agents Are Increasing CPU Demand

Wei identified agentic AI as a reason central processing units, or CPUs, are becoming more important inside AI data centers. An AI agent can carry out a sequence of tasks, such as retrieving information, using software and coordinating work, rather than simply answering one question.

Graphics processing units, or GPUs, and other accelerators handle much of the heavy computation. CPUs help organize tasks, process data and manage the surrounding system. More activity across the whole data center can therefore increase demand for several kinds of chips at once.

Goldman Sachs analyst Evelyn Yu also identifies stronger server CPU demand from AI agents as a key change over the past year. The bank expects AI demand to extend across GPUs, network chips and CPUs. Wei said almost all CPU suppliers using x86, Arm or RISC-V architectures are TSMC customers, giving the manufacturer exposure across different processor designs.

AMD chief executive Lisa Su said in Taipei on October 6 that the company planned a substantial increase in chip supply in 2027 and needed more advanced manufacturing capacity. AMD has extended its supply planning to cover three to five years, illustrating how customers are preparing well beyond the next quarter.

What Utilization Above 100% Means

KGI Securities forecasts that TSMC's 3 nanometer capacity utilization will exceed 120% in 2027. SemiAnalysis expects utilization to pass 100% in the second half of that year, with AI applications absorbing nearly 60% of total 3 nanometer output.

Capacity utilization compares production with a stated capacity benchmark. A forecast above 100% means analysts expect output to exceed that reference level, which can change as factories improve productivity or expand available capacity. The precise benchmark behind the 120% estimate was not specified.

SemiAnalysis's forecast would leave roughly 40% of 3 nanometer production for applications outside AI. That would make AI the majority user of the process, increasing competition for capacity among customers making different types of advanced chips.

Wei described the gap between advanced chip demand and supply as large. When asked whether demand for processes of 3 nanometers and below exceeded supply by 30% to 50%, he did not give a percentage. TSMC is working with customers to allocate wafer production among the processors and accelerators they need.

Packaging Is Another Constraint on Deliveries

TSMC's expansion challenge continues after chips leave the wafer factory. Advanced packaging connects processors, memory and other components so they can work together. For large AI products, limited packaging capacity can delay deliveries even when the individual chips are available.

Wei said TSMC's advanced packaging supply was tight enough to restrict customers' ability to bring products to market. He welcomed additional packaging capacity from other suppliers, because customers using TSMC wafers could complete more products and support further demand for its manufacturing business.

GlobalFoundries announced on October 8 a manufacturing agreement with TSMC worth about $2 billion over five years. It will produce silicon interposers in New York for TSMC's CoWoS packaging technology. An interposer is a connecting layer that allows chips and memory to communicate within a package.

The agreement is expected to begin expanded volume production in the first half of 2028, leaving a substantial wait before that additional supply arrives. TSMC is also developing alternative packaging substrate options to lower costs. Wei said those technologies would need about another year to mature before work with customers on production adoption.

Arizona and New Chip Processes Add to Costs

TSMC announced another $100 billion of investment in Arizona in July, increasing its planned total there from $165 billion to $265 billion. Wei said approximately four more factories would be built, covering advanced wafer manufacturing and later production stages, including packaging. The investment will support processes of 2 nanometers and below.

The Arizona total covers investment across multiple years, while the capital spending forecasts measure expenditure in individual years. TSMC has not set a fixed completion schedule for the additional $100 billion, saying the pace will follow customer demand. Construction is also being accelerated in Taiwan and Japan.

Arizona's second wafer factory is expected to begin volume production in the second half of 2027. That year is also expected to be the first full year of volume production for TSMC's 2 nanometer process. New factories bring depreciation costs, which spread the cost of equipment across its useful life, as well as operating expenses.

TSMC's next A14 process is scheduled for trial production in 2027 and volume production in 2028. Compared with N2, it is expected to deliver 10% to 15% more performance at the same power consumption, or reduce power use by 25% to 30% at the same performance, with nearly 20% greater chip density. Wei said advanced processes now take five to seven years to move from development through capacity preparation to large scale production.

Revenue Growth Must Cover a Larger Cost Base

Citi expects TSMC's revenue to grow by more than 40% in 2027, with AI revenue potentially approaching twice its previous level. Goldman Sachs forecasts dollar revenue growth of 42% in 2026 and 36.9% in 2027. For 2026, Morgan Stanley analyst Charlie Chan expects 41% to 45% growth, while Citi's Taiwan research head, Chen Chia-yi, forecasts 46%, above TSMC's July guidance of slightly more than 40%.

LSEG's compilation of estimates from 16 analysts puts third quarter net profit at NT$746.3 billion, an increase of 65% from a year earlier. That is an earnings forecast ahead of the October 15 announcement. Bank of America estimates 2027 earnings per share of NT$161.36, while Chang describes market expectations around NT$150.

Goldman Sachs forecasts gross margins of 67.2% in 2026 and 67.5% in 2027. Gross margin is the share of revenue left after the direct cost of making products. Chang expects the margin in 2027 to remain steady or rise by less than 0.5 percentage points as price increases help cover new factory and overseas costs.

Chan and Nomura analyst Cheng Ming-tsung expect advanced manufacturing prices to rise by 5% to 10% in 2027, with some mature processes potentially increasing by about 5%. TSMC has not confirmed the proposed increases. Its July outlook put the effect of expanding 2 nanometer production on second half gross margin at about three to four percentage points, partly offset by demand and cost improvements.

Wei said pricing must support continued research and factory investment while keeping customers competitive. The company's mature process expansion is also selective, focusing on areas such as image sensors in Japan and automotive and industrial applications in Germany. Demand for power management chips and sensors connected with AI is stronger than for many general consumer electronics products.

Higher Share Targets Depend on Future Earnings

UBS sees scope for TSMC's forward price to earnings ratio to reach 21, while Goldman Sachs estimates 22, compared with the current figure of 17.4. A forward price to earnings ratio compares a share price with expected future earnings. A higher ratio means investors are paying more for each unit of profit they expect the company to generate.

Citi raised its Taiwan share price target from NT$3,800 to NT$4,000, and Goldman Sachs increased its target from NT$3,100 to NT$3,300. Macquarie's target of NT$4,410 is the highest among the nine investment firms listed in an earnings preview. The targets reflect different assumptions about growth, profits and the valuation investors may accept.

Citi also points to co packaged optics, or CPO, as a potential growth driver. The technology places optical connections close to computing components to move data quickly. Hsieh's October commentary described demand for optical communications equipment extending toward 2029, while warning that server assemblers face rising costs for processors, memory, cooling and circuit boards.

TSMC is checking data center construction locations, progress and deployment needs alongside customer forecasts before committing to capacity. Wei explained that individually optimistic customer plans cannot simply be added together to determine total demand. The company wants delivered chips to enter service rather than accumulate in inventory.
