Analyst forecasts indicate hyperscaler capex growth is peaking as AI infrastructure funding diverges between hyperscalers and dedicated compute platforms.
The AI industry's boom continues, but structural fissures are emerging at the funding layer. According to Founder Securities' chief economist Yan Xiang in his latest monthly AI macro tracker, North America's five hyperscalers posted yet another record quarter of capital expenditure, yet consensus growth expectations have already locked in 2026 as the peak. Simultaneously, the bond market has begun repricing cloud issuers distinctly, with credit spreads diverging markedly. This signals a shift in the AI arms race from broad-based high growth to structural divergence.
Released in early October, the report frames AI conditions across five layers: capital flows, construction, the price chain, revenue output, and macro transmission. The verdict is clear: construction, pricing, revenue, and macro conditions remain buoyant. The stress concentrates at the funding layer.
**Capital Flows: Volume Surging, Expectations Peaking**
Q2 2026 saw the five hyperscalers' combined capital expenditure reach $182.5 billion—a fresh quarterly record and 87% year-over-year growth. Amazon led at $54.2 billion, followed by Alphabet ($44.9 billion), Microsoft ($35.8 billion), Meta ($31.1 billion), and Oracle ($16.5 billion), which alone declined sequentially.
Year-over-year growth tells a more revealing story. Combined capex growth stabilized in the 70–75% range through 2025, then climbed to roughly 90% in the first half of 2026. Investment has not meaningfully decelerated, yet the intensity of spending is rapidly outpacing internal cash generation. Capex now equals 98% of operating cash flow on a quarterly basis, and three of the five firms have flipped to negative free cash flow.
Bloomberg consensus projects 2026 combined capex at approximately $790.3 billion—up 86% year-over-year and the peak growth rate of this cycle. Growth is expected to decelerate to 35% in 2027 and fall to single digits by 2028–2029. Yan Xiang emphasizes that peaking growth does not mean shrinking spending; combined capex is still projected to reach roughly $1.31 trillion by 2030, with no absolute reversal. However, decelerating growth expectations will pressure upstream hardware vendors' revenue.
Bond markets are already repricing the expansion. As of September 21, 2026, the five hyperscalers had issued approximately $229.1 billion in debt year-to-date. Amazon accounted for roughly $98.5 billion and Alphabet for roughly $80.6 billion—together 78% of the total. Oracle and Meta each issued about $25 billion; Microsoft issued nothing. The repricing is evident in 10-year USD spreads over comparable Treasury yields: Alphabet's new-issue spread widened from 47 basis points in April 2025 to 85 in August 2026; Amazon's from 55 to 80; Oracle's from 105 to 145. Over the same period, the A-rated corporate bond index OAS remained broadly flat at 60–70 basis points, signaling that the widening is driven by issuer-specific supply and leverage rather than a broad retreat in risk appetite.
Secondary markets price by balance sheet as well. As of September 18, 10-year benchmark G-spreads for the five firms were: Oracle at approximately 197 basis points, Meta at approximately 100, Amazon at approximately 78, Alphabet at approximately 77, and Microsoft at approximately 40. Since the start of the year, the first four have widened by 23–33 basis points, while Microsoft has been essentially flat.
Equity financing into AI startups remains highly concentrated. AI startup quarterly fundraising reached $247 billion in Q1 2026 and $147 billion in Q2, representing 81% and 72% of global venture capital, respectively. OpenAI alone raised over $100 billion in a single round. Since Q3, Mistral closed €3 billion (approximately $3.4 billion), Zhipu $5 billion, and Crusoe $3.9 billion. Structured financing continues to shift toward risk deferral: Nvidia provided up to $105 billion in residual value guarantees for SB Energy's Ohio project; a Meta subsidiary provided lease guarantees for CleanSpark's $2.28 billion high-yield bond for its Georgia project; ByteDance completed a $29.6 billion syndicated loan; and SoftBank is advancing an $11.87 billion syndicated loan and high-yield bond combination to fund its OpenAI investment. Debt is migrating from tech giants' balance sheets to project companies, private credit, and related parties—a trend eroding chain transparency.
**Construction and Price Chain: Supply Constraints Persist, Price Acceleration Slows**
Funding continues translating into physical construction. Data center construction spending reached $4.36 billion in June 2026 (inflation-adjusted), a record high and 44% year-over-year growth—5.2 times the level at ChatGPT's launch. Across North America's eight core markets, data center IT load under construction rose to 7,481 megawatts in the first half of 2026—a record—while vacancy fell to a historic 1.4%.
Power remains the binding constraint. GE Vernova's gas turbine backlog and paid capacity reservations totaled 116 gigawatts in Q2 2026, more than doubling from 50 gigawatts in Q1 2025 over six quarters. Production slots are sold out through 2030 and beyond. The company's capacity plan calls for only modest growth—from approximately 20 GW annually in mid-2026 to 24 GW by mid-2028—vastly outpaced by order growth.
Upstream capacity shows no restraint. TSMC raised 2026 capex guidance three times to $60–64 billion; at the midpoint of $62 billion, this represents roughly 50% growth over 2025's $40.9 billion. Japanese semiconductor equipment global billings reached ¥597.9 billion (approximately $3.8 billion) in August 2026—a series high and 47.4% year-over-year growth, with gains accelerating for six consecutive months.
GPU rental rates rose to $3.96 per GPU-hour in September 2026—up 2.6% month-over-month and marking three consecutive monthly records, double the $1.93 rate in Q3 2025. Memory drives this cycle's price gains, but momentum is decelerating: the DRAM spot price index's month-over-month gain narrowed from 19.8% in June to 6.2% in August, while DDR5 contract prices rose to $130 in July, a 13% monthly gain. Across the four DRAM and NAND price lines, peak monthly gains have all been reached; the price cycle is in decelerating uptrend.
Token costs have collapsed beyond 50% from their peak. Silicon Data's LLM token cost index fell from $2.07 in late May 2026 to $0.97 in early September. Yan Xiang interprets the coexistence of rising list prices and falling transaction prices as migration of routine workloads toward cheaper models—structural cost reduction rather than weakening demand.
**Revenue Output and Macro Transmission: Full-Chain Acceleration, Structural Rather Than Volume Risk**
Output-layer momentum remains broad. TSMC's August 2026 revenue reached NT$514.8 billion (approximately $16.2 billion)—a monthly record and 53.3% year-over-year, marking four consecutive monthly highs. Taiwan's five major foundries posted combined August revenue of NT$2.0334 trillion (approximately $64.0 billion), up 86.7% year-over-year and accelerating from 65.8% in July. South Korean semiconductor exports reached $46.65 billion in August—up 209% year-over-year and holding above $40 billion for three consecutive months. Global semiconductor monthly sales hit $146.8 billion in July, up 137% year-over-year.
Nvidia's data center segment posted $89 billion in revenue for the May–July 2026 quarter, up 117% year-over-year, with growth accelerating for four consecutive quarters. The three major cloud providers continue to accelerate: Google Cloud grew 82% year-over-year in Q2, Microsoft Azure accelerated to 43%, and Amazon AWS moved from 17% in early 2025 to 37%. OpenAI's annualized revenue exceeded $40 billion in August 2026, double the end-2025 level; Anthropic's ARR rose from approximately $9 billion at end-2025 to $65 billion.
Measured by historical percentile rankings since 2024, seven indicators sit at the 100th percentile: South Korean exports, Taiwanese foundry output, global semiconductor sales, Chinese AI exports, and the three cloud providers' revenue growth. TSMC revenue and Taiwan export orders both rank at approximately the 90th percentile.
