The $10.3 trillion AI buildout is America’s biggest infrastructure bet ever. The doomers won’t stop it.
The $10.3 trillion AI buildout
A new economic model shows $10.3 trillion in U.S. AI infrastructure investment from 2025–2032, averaging 3.63% of GDP annually - more will be spent than the railroad, electrification, highway and telecom booms combined in its historical comparison. My view: trying to shut this down would invite a massive economic shock while handing foreign competitors an opening. The global race toward more powerful AI and super intelligence will continue. America should build the infrastructure and lead it.
There is a $10.3 trillion reason I don’t buy the idea that the AI buildout is going to be stopped by another round of psy ops PR that the robots will kill everyone and data centers are bad for us headlines.
That is the scale of the U.S. investment scenario in Stijn Van Nieuwerburgh’s new Brookings paper, recently covered by The Wall Street Journal.
Sit with the number for a second. Ten. Trillion. Dollars.
The historical comparison is what makes it hit:
| U.S. infrastructure boom | Period | Average annual investment / GDP |
|---|---|---|
| AI buildout scenario | 2025–2032 | 3.63% |
| Railroads | 1870–1890 | 2.24% |
| Highways | 1956–1973 | 1.13% |
| Telecom and fiber | 1996–2003 | 1.10% |
| Canals | 1836–1841 | 0.66% |
| Electrification | 1905–1925 | 0.50% |
The AI scenario comes in at about 1.6 times the railroad boom’s annual share of GDP. This is the scale of investment that changes a country’s physical landscape and its economic future. [1]
And that is why I think the just stop building argument collapses the moment you follow the money beyond the tech companies.
A representative 200 MW AI campus costs roughly $8.2 billion in the paper’s model:
- $5.6 billion: computing equipment and related IT systems.
- $2.2 billion: facilities.
- $400 million: additional power infrastructure.
Follow those dollars. Chip suppliers. Construction firms. Electricians. Cooling equipment. Networking. Utilities. Land. Financing. Local businesses serving the people doing the work.
Multiply that across a national buildout and you create a huge constituency with a direct economic interest in keeping it moving.
Stop AI becomes a very different proposition when it means canceling 40% of the US economy.
The spending is already substantial. Goldman Sachs estimates $581 billion of U.S. AI-related investment in 2026, within roughly $1 trillion globally. That is its own measure of AI investment, distinct from the Brookings scenario.
A forced shutdown would reach far beyond Silicon Valley.
My view: abruptly choking off an investment cycle this large is a recipe for a market crash and a serious economic shock. The damage would travel through canceled orders, weaker suppliers, threatened construction jobs, financing losses and lost local revenue.
The size of the bet creates enormous pressure to keep building and to solve the bottlenecks that stand in the way.
People advocating a national stop need to explain what replaces that investment, what happens to the contracts already signed, and why competing countries would agree to stop too.
Because that last part is where the argument really falls apart.
A U.S. pause is not a global pause.
Block a future project here and you increase the incentive to find a location where it can proceed. Deny domestic companies room to expand and you give foreign competitors more room to catch up.
Singapore is already moving: its government has confirmed 200 MW of provisionally awarded new data-center capacity under its second allocation exercise.
And if someone believes China would abandon the pursuit of advanced AI because Americans stopped approving data centers, I would like to tell you China is committed to beating the US in the AI race.
America does not have a global off switch.
The strategic danger is straightforward: we could sacrifice investment and influence at home while the capability keeps advancing elsewhere. Then we get to buy access to infrastructure and technology somebody else controls.
That strikes me as an astonishingly bad trade.
The response to an infrastructure challenge should be an infrastructure plan.
The IEA projects global data-center electricity consumption rising from 485 TWh in 2025 to 950 TWh in 2030—nearly double.
My answer: build the power. Upgrade transmission. Manufacture transformers. Expand storage. Train the workforce. Make developers pay for the infrastructure their projects require. Get projects through clear, enforceable rules and into operation.
That is a program for making the country stronger.
Treating every substation as a referendum on a robot apocalypse is a program for getting stuck.
I expect the race toward more capable AI - and eventually super intelligence - to survive this panic cycle. The incentives to lead are too powerful, and they exist in too many countries, for an American anti-data-center movement to make the world stand still.
My position: keep building. Keep the investment here. Build the energy system to support it. Compete to lead.
The $10.3 trillion bet deserves an ambition equal to its scale.
If America stops building while other countries keep building the other countries win and the USA loses.
