Slok flags a survey of 396 enterprises that found AI adaptation hasn’t improved gross margins in aggregate, with 81% of firms noting a “moderate-to-high gross margin impact” from their AI spending, while 63% saw a 6 to 15pp decrease.
Are companies losing control of their AI spending forecasts?
Core argument: Only 11% of the 396 enterprises surveyed by Mavvrik and Benchmarkit forecast their AI spending within 10% of actual, down from 15% a year earlier.
A new survey by Mavvrik and Benchmarkit of 396 enterprises finds that companies are adopting AI faster than they are building the financial controls to keep its costs in check. Only 11% of firms forecast their AI spending within 10% of actual, down from 15% last year. The survey also shows that those misses are changing decisions, with 62% of firms saying an unexpected AI cost altered a business decision and one in four delaying or canceling an AI initiative. The impact is showing up in profitability too, with 81% of companies reporting moderate-to-high gross margin impact from AI costs, including 63% who see a 6 to 15 percentage point decrease.

Tech’s Trillion-Dollar Internal Inconsistency— Wall Street analysts covering technology project the sector's operating cash flow will more than double to roughly $2.4tn by 2028, a gain of over $1.2tn, while analysts covering the rest of the S&P 500 — technology's customers — project those firms will add far less cash flow. These sector-by-sector forecasts are internally inconsistent.
How Much Revenue Does The AI Buildout Need In 2030?— The authors estimate AI capital spending of $560bn in 2026 and, in a high-investment case, $3.5tn of net AI capital in service by 2030, requiring roughly $1.3tn in annual infrastructure revenue once depreciation, operating costs and a 15% return are covered. That implies 7.4x growth from current annualized revenues, with downstream revenues of $1.9–2.6tn.

Gains attenuate up the production chain: synchronous agents raise lines of code 741% and pull requests 65% but releases only 20%.
AI Summary.Across 12 middle-income countries, call-center employment grew in line with other white-collar office work before the spread of AI chatbots but has since stagnated or declined even as other white-collar jobs held up.

A Revelio Labs analysis finds global call center employment is now 5.3% under its December 2023 peak. Call center employment started diverging from other white collar work in middle income countries around November 2022, when ChatGPT was released.
Is AI reducing call center employment in middle-income countries?
Core argument: Across 12 middle-income countries, call-center employment showed sluggish growth or outright declines after ChatGPT’s release, while other white-collar office and administrative roles remained fairly robust.
Across the 12 middle-income countries, the pattern is recognizable: in the pre-ChatGPT era, call-center headcount generally kept pace with other office and administrative, "white-collar" roles. In the post-ChatGPT era, we see sluggish growth or outright declines in call centers—even as the rest of white-collar work looks fairly robust. So, although we cannot observe which firms replace people with chatbots, this divergence in headcounts between call centers and the rest of their labor markets makes AI’s potential role in this trend hard to wave off. Moreover, call centers’ high-volume, scripted work is exactly the profile the International Labour Organization flags as most exposed in these countries. The industry is shrinking because hiring slowed, not because separations picked up.

AI’s Most Exposed Industry Keeps Hiring— Call center employment in the Philippines has reached nearly 2m workers and has grown every year since 2016, including through the artificial intelligence boom. As AI lowers the cost per customer interaction, companies are buying more of these services rather than fewer — an example of Jevons paradox.
Looking for the Ladder— The article argues that the hiring downturn in occupations most exposed to generative AI reflects interest-rate sensitivity rather than AI itself, since roughly 38% of workers in the most AI-exposed quintile work in information, finance and insurance, and professional and technical services, versus under 2% in the least-exposed quintile.

Estimated associations with occupational AI exposure are positive but not statistically significant.
AI Summary.The United States generates almost twice as much economic output per dollar invested as China, the opposite of what would be expected from a mature developed economy versus a fast-growing economy catching up. The gap points to overexuberance in Chinese investment.
Robin Rivaton and Ben SouthwoodWorks In Progress
Date Posted:
The US generates ~2x as much output per dollar of capital as China. Rivaton and Southwood argue that relentless competition among Chinese subnational governments, who account for ~85% of public expenditure, drives industrial growth at the cost of reduced capital efficiency.
Does China get less economic output per dollar invested than America?
Core argument: The United States obtains nearly twice as much GDP from every dollar invested as China does, measured by the capital efficiency ratio of output to invested capital stock.
Overexuberance is visible in economic data. Interest rates that banks pay to depositors are capped, giving banks artificially cheap capital. Entrepreneurs may be backed to attempt extremely unlikely, borderline schemes. The capital efficiency ratio measures how much output a country gets out of the capital stock it has invested – how many dollars of GDP a country can buy with a dollar of investment. The United States gets almost twice as much economic output out of every dollar it invests as China does, precisely the opposite of what we would expect from a developed country with a mature economy versus a rapidly growing country playing catch up.

The United States obtains nearly twice as much GDP from every dollar invested as China does, measured by the capital efficiency ratio of output to invested capital stock.
China’s capital efficiency inverts the expected pattern, in which a rapidly growing catch-up economy would extract more output per dollar of investment than a mature developed economy.
Overexuberance is visible in Chinese macroeconomic data, with China’s investment generating less economic output per dollar than that of the United States.

The Year of the Trojan Fire Horse: China’s Imbalanced Economy and Unrelenting Mercantilism— About 30% of Chinese industrial companies are unprofitable "zombies" kept alive by subsidies far larger than those elsewhere, rather than exiting amid falling industrial producer prices. Countries with large increases in manufactured imports from China also saw slowdowns in domestic manufacturing, including declining manufacturing shares of output across most of Southeast Asia.
Xi’s Superpower Ambitions Fuel a Dangerous Debt Spiral in China— China's credit to the nonfinancial sector—corporate, government and household borrowing—topped 300% of gross domestic product, 60 percentage points above its end-2019 level and larger than in the US, according to the Bank for International Settlements. The International Monetary Fund estimates broad Chinese government debt, including local financing vehicles, reached 127% of GDP, up from 98% in 2020.
Is China’s High-Quality Investment Output Economically Viable?— China's technological progress and infrastructure do not refute claims of overinvestment, since overinvestment often produces real physical assets and technological gains yet still counts as overinvestment when it generates less real value than the resources, subsidies, and transfers it consumes. When such losses are capitalized, assets are carried above their real economic value.
AI Summary.Goldman Sachs estimates that artificial intelligence–related stocks account for 57% of Chinese equity trading turnover and that nearly $5tn in AI-related market value has been created, including $2tn from new listings.

China accounts for 77% of global token usage, but only 22% of token spending, according to a GS analysis. Kedrosky notes, “This is what widespread AI adoption at low prices looks like. And it is the channel through which Chinese competition will pressure prices elsewhere.”
How large is AI's footprint in Chinese markets and supply chains?
Core argument: AI-related stocks account for 57% of trading turnover in Chinese equities, and Goldman estimates almost $5 trillion in AI-related market value has been created since the DeepSeek moment, including $2 trillion from IPOs.
AI-related stocks now represent 57% of trading turnover in Chinese equities. Since the DeepSeek moment, Goldman estimates almost $5 trillion in AI-related market value has been created, including $2 trillion from IPOs. AI dominates Chinese equity markets even more than it does U.S. markets. It's a one-factor world. China shipped 97% of humanoid robots in the first half of 2026. Alongside China’s 75% share of EV production and 80% of battery production, China basically owns the physical side of AI and AI-adjacent technologies. The industrial base behind the AI buildout is already concentrated in China: 60% of global transformer production capacity, 60% of PCB and optical-module production, 77% of new foundry capacity, and 90% of rare-earth refining. There are more than 880 AI-related companies focused mainly on China’s domestic market, with $3.2 trillion in market value. To put it in context, this is nearly half the total market of the Nasdaq at the peak of the dot-com frenzy.

Who’s Afraid of Chinese Models?— Demand for frontier artificial intelligence models exceeds supply because computing capacity is scarce, allowing chip suppliers and their customers to resell compute at high margins. The author argues alarm over Chinese models is overblown, expecting the inference market to grow faster than training costs so labs can thrive at lower prices.
Semiquincententacles— Leading artificial-intelligence labs are moving to usage-based token pricing on a cost-plus basis that includes total ownership costs, pushing token prices higher and giving some enterprises reason to migrate to cheaper open models. Frontier models remain necessary for cybersecurity, distillation training, agents, and scientific discovery, where maximum performance is required.
Why .400 Hitters Disappeared — and What It Means for AI— Artificial intelligence models' capability gains are shrinking in percentage terms, falling from about 15% relative to the baseline early on to roughly 10% for the same absolute increment, narrowing the gap between frontier and good-enough models. The author argues this points to a commoditizing market where price, not minor model differences, becomes the main differentiator, pressuring frontier firms' margins.

Are foreign investors funding America's AI buildout?
Core argument: Foreign investors held roughly $4.9 trillion of US-listed shares in AI-centered industries at the end of June, a sum roughly equivalent to Germany’s annual GDP, according to Bloomberg Economics’ analysis of Treasury data.
The AI boom is creating massive demand for high-end chips and new pools of savings in places that make them like South Korea and Taiwan which are flowing to fund American tech companies and their $9 trillion AI build out. Foreign investors made roughly $1.5 trillion in net purchases of US equities alone since the beginning of 2024 through the end of July. A Bloomberg Economics analysis of Treasury data shows that in 2025 roughly 20% of all foreign holdings of US equities were in AI-related sectors, up from roughly 10% in 2019. That number has grown with soaring valuations since then. But even assuming that 20% level, foreign investors had about $4.9 trillion of exposure to US-listed shares of companies in industries at the center of the AI boom at the end of June. That’s roughly equivalent to Germany’s annual GDP.

Movie and TV employment alone has fallen by more than 100,000, nearly one-third of the sector, while publishing has lost more than 70,000 jobs]. The effects of AI are hard to disentangle from other factors currently affecting arts businesses, like consolidation in Hollywood, offshoring of content production, or the continued displacement of traditional media providers in favor of social media creators.
