AI Summary.Corporate profit margins, long regarded as one of the economy's most reliably mean-reverting series, have risen continuously so far this century. Measured through the national income accounts used in calculating GDP, profits now take a larger share of the economy than on the eve of the 1929 crash.

Since 2000, post-tax corporate profits as a share of GDP have trended upward across cyclical setbacks and are now near an all time high, above their 1929 level.
Have corporate profit margins stopped reverting to the mean?
Core argument: Corporate profits measured in the National Income and Product Accounts take a larger share of the U.S. economy than on the eve of the 1929 Great Crash.
Throughout the 20th century, profit margins were regarded as one of the purest mean-reverting series in the economy. So far this century, however, margins have done nothing but rise. Measured with the National Income and Product Accounts, part of the GDP calculation, profits are currently taking a bigger share of the economy even than on the eve of the Great Crash in 1929. The series comes with a lag, so we can assume the profit share on this basis is comfortably at a record by now.

US Focus: The Effect Of Soaring Profits— US nominal pre-tax corporate profits in the national accounts grew 23% over the past year, a pace not seen outside post-recession spikes since the mid-2000s. Wider margins were the key driver, as domestic profit growth far exceeded the 8% rise in corporate value added, pushing margins near all-time highs while the labor share hit new lows.
The Post‑COVID Decline in the Labor Share— The share of US national income paid to workers fell 1.6 percentage points below its pre-pandemic level, reaching a post-war low. The authors find this decline stems mainly from changes within industries rather than shifts in activity across sectors, following cyclical patterns seen in earlier recessions.
Are US Corporate Profit Margins Too High?— US after-tax non-financial corporate profit margins remain elevated by historical standards, estimated at 7.6% versus a post-1949 high of 8.2%, while employee pay as a share of non-financial corporate gross value added has fallen from 66% to 56%. One argument holds that subdued demographic growth leads companies to prioritize maximizing margins over expanding capacity.
AI Summary.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.

Beginning with capex projections, Gildea/Azhar derive for their high-growth case a $1.3T annual AI-infrastructure revenue hurdle for 2030. This covers $771B of depreciation and operating costs, plus a 15% return on $3.5T of net capital in service.
How much annual revenue must AI infrastructure generate to justify investment?
Core argument: In a high investment case with $3.5tn of net AI capital in service, the authors estimate AI infrastructure must generate $1.3tn of annual revenue by 2030, requiring 7.4x growth (59% CAGR) from today’s annualized revenues.
We estimate AI CapEx to be $560B in 2026, 64% of the total declared by the hyperscalers. Unfinished facilities can’t generate revenue, so the investment bill and the productive asset base will grow at different speeds. [In the high investment case], by 2030 we see $3.5T of net AI capital in service. The largest component [of the revenue hurdle] is the $555B in compute depreciation. We model lifespans at the current 5-6 years. Shell depreciation and OpEx combined contribute about a further $216B to the required revenue hurdle. [Adding a 15% return on net capital brings required annual infrastructure revenue to $1.3T]. Reaching the $1.3T hurdle would represent 7.4x growth (59% CAGR) from today’s annualized revenues. For its customers to earn 30-50% gross margins, downstream revenues need to be $1.9-2.6T. [Editor’s note: Van Nieuwerburgh’s far larger figure of $3.7T covers mature revenues from projects completed through 2032, using commissioning capital and a 50% infrastructure operating cash-flow margin. This estimate instead charges depreciation and operating costs plus 15% on net capital in service in 2030. Different horizons and cost conventions prevent a direct comparison. Van Nieuwerburgh also has a much higher capex estimate.]

The spread between 10-year French OATs and German Bunds has widened at a pace seen only during the eurozone sovereign-debt crisis. John Authers warns that France “satisfies all the classic conditions for a major debt crisis.”
Do high tax burdens limit France and the UK's deficit options?
Core argument: The spread of 10-year French OATs over German Bunds has risen at a pace matched only during the worst days of the euro-zone sovereign debt crisis in 2011 and 2012, fueling talk of a second crisis centered in Paris.
Only in the worst days of the euro zone’s sovereign debt crisis, in 2011 and 2012, has the [spread of 10-Year French OATS over German Bunds] risen so fast. Talk of a second euro-zone crisis, this time with an epicenter in Paris, is growing, and it’s easy to see why. Why is this more of a problem for France and the UK? Beyond their deficits, they also shoulder much higher tax burdens than the US. Tax revenues are 25.2% of GDP in the US, the lowest of the major developed economies - but 35.3% in the UK and 43.9% in France. It’s hard to imagine after decades of tax-cutting, but a US politician could deal with the deficit fairly easily with a tax hike. It’s not clear that option is open to French lawmakers, even if they could somehow persuade voters to go along with them. The populist politicians of left and right, who currently look well placed in next year’s presidential elections, are in any case unlikely to try.

If interest rates rise 1pp above CBO’s current extended baseline (a mean rate of 4% over 2026–2056), CBO projects federal debt held by the public will be 222% of GDP in 2056, versus 175% under the current baseline.
How much would higher interest rates raise projected federal debt?
Core argument: CBO projects that under a scenario in which interest rates rise to 1 percentage point above its extended baseline, debt held by the public would reach 222% of GDP in fiscal year 2056, 47 percentage points above the extended baseline.
Under a scenario in which interest rates increased until they were 1 percentage point higher than in CBO’s extended baseline, primary deficits—that is, deficits excluding net outlays for interest—would average 2.3% of GDP over the 2026–2056 period, 0.2 percentage points larger than in the extended baseline. Debt held by the public would grow to 222 percent of GDP in fiscal year 2056, 47 percentage points larger than in the extended baseline. Average annual GDP growth over the 2026–2056 period would be 0.1 percentage point slower than in CBO’s extended baseline, and the average interest rate on federal debt would be 0.7 percentage points higher.

Tech analysts expect sector operating cash flow to more than double to ~$2.4T by 2028. Analysts covering other S&P 500 sectors (tech’s customers) see far less cash growth in their sectors. Slok “raises the question of who exactly will be writing all those checks to buy AI services.”
Are tech cash flow forecasts inconsistent with customers' projected growth?
Core argument: Analysts covering the tech sector expect its operating cash flow to more than double to roughly $2.4tn by 2028, an increase of over $1.2tn.
Wall Street equity analysts work in sector silos, and when you add up their forecasts, the numbers are internally inconsistent. The analysts covering tech expect the sector's operating cash flow to more than double to roughly $2.4 trillion by 2028, an increase of over $1.2 trillion. Meanwhile, the analysts covering the other sectors in the S&P 500, which are tech's customers, expect those companies to add much less operating cash flow. In other words, the tech silo is betting on a future in which demand for AI and tech services explodes, while the silos covering the companies that would pay for those services see a much more modest outlook. Both cannot be right at the same time. The bottom line is that either tech's customers will generate a lot more cash than their analysts expect, or tech's cash flow forecasts are too optimistic, which raises the question of who exactly will be writing all those checks to buy AI services.

Stijn Van Nieuwerburgh projects ~$10.3T will be spent on the AI buildout over 2025–2032, averaging 3.63% of GDP. He estimates 2/3 of that spending reflects IT equipment and one-third real estate and associated power infrastructure.
How much of the planned data center pipeline gets built?
Core argument: Using Cleanview project-level data from July 2026, the authors estimate roughly 57 GW of operating U.S. data center capacity against a planned development pipeline of roughly 509 GW, which they stress is not a completion forecast.
The required investment is enormous. A representative 200 MW AI training campus costs roughly $8.2 billion, about two-thirds of which reflects IT equipment and one-third the real estate and associated power infrastructure. We estimate that 183 GW is completed by 2032 with a further 118 GW completed after 2032. This pipeline will trigger about $10.3 trillion dollars of investment over 2025–2032. At an average of 3.63% of GDP per year, the projected buildout would be larger relative to the economy than the major U.S. canal, railroad, electrification, highway, and telecommunications investment booms. It would double the electricity consumption of the entire U.S. residential sector.
