Without Data Centers, GDP Growth Was 0.1% in the First Half of 2025, Harvard Economist Says (fortune.com) 83

U.S. GDP growth in the first half of 2025 was driven almost entirely by investment in data centers and information processing technology. The GDP growth would have been just 0.1% on an annualized basis without these technology-related categories, according to Harvard economist Jason Furman. Investment in information-processing equipment and software accounted for only 4% of U.S. GDP during this period but represented 92% of GDP growth.

Renaissance Macro Research estimated in August that the dollar value contributed to GDP growth by AI data-center buildout had surpassed U.S. consumer spending for the first time. Consumer spending makes up two-thirds of GDP. Tech giants including Microsoft, Google, Amazon, Meta and Nvidia poured tens of billions of dollars into building and upgrading data centers.

  • Seems fairly arbitrary.

    Why not exclude whatever else contributed to growth too, so you can say there was no growth at all?

      One is that data centers are the playground of rich people that add little to the economy, ie, few workers, lots of money. Two, to get a handle of how badly tariffs are, and how bad the MAGA economy really is. Biden was adding jobs, adding value to peoples lives every day. Building out projects that benefit society. MAGAs threw that away and is just concentrating wealth to a few people.
      • The claim behind the massive buildout of AI datacenters is that they will be massively profitable because they will allow development of new technologies and find ways to make existing technologies more efficient. That's a long term increase in the economy and a benefit to society. FWIW, I believe the claim is overblown and possibly entirely mistaken.
        • I do hope that there will be massive breakthroughs in medicine, materials, physics... etc. I also hope that GDP is re-defined now to take into account that there are human beings in America, who needs health care, food, education, etc... I think there should be a 'happiness index'. The politician who can make that go up has my vote. Now we seem to just watch the stock market, and that seems to be disconnected from most peoples lives.

        Even though I supported Biden, he didn't create jobs. The U.S. economy created jobs. He merely didn't construct the clusterfuck that el Bunko has created. The U.S. economy sort of runs along just fine without screwing with it. Naturally U.S. companies decided to pull in their plans because they can never figure out what that idiot it going to do them next. The tariffs are enough to drive many small business out of business because they cannot source the parts they need reliably or cost effectively.

          This is true.

          The U.S. economy sort of runs along just fine without screwing with it.

          This is nonsense. There has never been a time when it has not been screwed with, so there's nothing at all to support that statement.

          Add to that, el Bunko totally screwed the farmers.

          He screwed them last time, then there were bailouts, so they figured they could get more bailouts. So they voted for him again. He screwed them much worse this time, though. Many of us tried to warn them, but they dismissed us as a bunch of libtards, because they are stupid fucksticks. Farmers may be smarter than the average nerd thinks, but only because they thin

          • I'm not sure "farmers" even exist the way they did 50 years ago. After big business had its way with agriculture, "farmers" are now Mexicans working on someone else's land for sub-minimum wage, mostly.

            A lot of people might identify as farmers because their parents had one in the 70s, and a couple of zucchini plants on the porch. But they would be entirely disconnected from the business and economics of agriculture.

            • Last I looked there was still a surprising amount of acreage in family farms, even though it's steadily waning. Maybe you're right about mischaracterization, though.

      While I'm not 100% sure myself, there is some speculation that a lot of datacenters being built today will never actually be used at capacity, and may in fact never be used at all if the AI bubble pops. I think there will be growth in AI at some point, but right now it's fairly unhealthy growth, and doesn't seem long-term sustainable at the rate the tech pushers keep saying. Maybe those datacenters can be utilized in other ways, or will be altered for whatever the next form of automation / AI will be, but I do believe there may be a bit of merit to those saying we've overbuilding for a trend that may end up not being able to sustain the projected current growth trajectory.

        I'd wonder how long these data centers stay productive given how quickly the technology is still changing. What's the expected operational lifespan on a data center? The technology in the buildings would be "current tech" for how long? 3 or 4 years? The building will last longer than that, or at least I would hope so, which can mean the technology can be updated and not need to start from nothing. I don't know how data centers work on this scale, and it could be nobody really knows since this is a lot

      And it's a massive bubble. In the very near future the winners will shake out and we're going to have a enormous economic collapse.

      If we had competent leadership in Washington they would be getting ready for that but well, you know.

      Meanwhile the trade war is hammering manufacturing jobs. It turns out that just cranking tariffs doesn't magically create jobs. It costs us jobs because other countries do retaliatory tariffs cutting off our access to their markets. Corn and soybean Farmers might get bailed out but nobody else does. And fun fact those corn and soybean Farmers aren't salt of the earth they're millionaires who have been buying up land from small family farms going out of business for ages.

      Basically it's a classic case of a combination of an unsustainable bubble and a weak economy that was barely recovering from the last round of damage done to it by incompetent stewardship. This next crash is going to hurt

      Because these are investments, not sales. Accounts are being drained and not refilled because the expected sales have not arrived yet. This cannot continue. It feels like late in the DotCom boom and many of remember that time well as well as what happened next.

    USA's economy is addicted to bubbles. Without one bubble after another, we wouldn't know what business to be in. We can't manufacturer as extensively as China because we don't have a Xi keeping wages down, we have no fashion sense like France, we don't have Venice-like tourism because GOP scares off visitors (Iraq war era, not just orangeshirts), and we don't have great ruins like Machu Picchu because we tore them down to make casinos.

    Our under-taxed plutocrats have giant piles of cash to invest in speculative shit, which often pops, yet we hope a new fad on the block replaces it in time: the Hype Industrial Complex.

    • If the US is in a bubble, but we always are, then it should be the case that the top few companies, those in whatever the current bubble industry, dominate the market.

      What the numbers say is that the top 10 companies in the S&P500 (i.e. 2% of those 500 companies) now account for a larger share of its total valuation - 38% - than ever before (since at least 1880).

    Job growth in the US is in the toilet along with consumer confidence. Massive inflationary tariffs, the impending death of democracy and rule of law. What's amazing is that the stock market has continued to post gains in the face of all the bad news. It is almost entirely driven by investments in tech, which appears to be immune.

    But not everyone is convinced this will hold. Gold hit $4,000/oz recently. I bought some a couple of weeks ago and I'm up about $2k already, I wish I had bought more.

    • It is almost entirely driven by investments in tech, which appears to be immune.

      In the 2000's, I remember hearing the exact same thing about real estate. That's a great sign you're in a bubble - everyone believes that the sector is immune from corrections. And it always is, right up to the point that it isn't.

      • Right, but the dotcom bubble collapsed at least partly because so many companies had huge valuations but no revenue or real product.

        That's not the case here. The AI companies have real working product, hundreds of millions of active users, and significant revenue. You can argue that they are overvalued but that may only result in an eventual correction.

        • "have real working product"

          A few of them do, but the product they have is not the product they claim to have.

          "hundreds of millions of active users"

          We know these user counts are typically inflated, and we know these users are mostly not paying.

          "significant revenue"

          I'm hearing a bigger share of this is "circular investment" (masturbatory illusion) and not money paid by customers for a product that they use.

          • >> we know these users are mostly not paying

            Maybe you should show some evidence for all those things you know.

            • Evidence: Launch an updated Chrome browser, Microsoft product, conduct a Google search, or open a random page on Facebook. You will be presented with unsolicited AI-generated content. You are now a "user" of AI, and you have paid nothing. Industry-standard practice.

              • >> You will be presented with unsolicited AI-generated content

                And you know this how? I'm not interested in baseless speculation.

                Even if true, you will also have to show evidence that the AI companies are counting that in their user statistics.

  • It's hard to believe these numbers.

    Government spending shows up in GDP. With the MASSIVE recent government spending, I feel like there should be more than 0.1% GDP growth without tech.

    That's not to say that GDP growth due to government spending increases is good. Quite the opposite, that sort of artificial GDP growth is very bad. But, I do feel like the over spending from the last two administrations has been done with significant specific intent to drive GDP.

    • You would well be right. Let's say increased government spending boosts GDP by 4%, yet the overall economy (excluding datacenters) grew by only .1%. To me that implies the rest of the economy shrank by 3.9%.
