US second-quarter growth revised up to 2.2%, fueled by consumer spending, AI investment, and stock-market wealth effects
Commerce Department figures put US second-quarter growth at 2.2%, up from a 1.5% estimate, as consumer spending rose at a 3.8% pace. Chip imports cut that total, so an AI pullback would hit hardest through the stock gains funding wealthy households' spending.

What happened
- Imports rose at a 12.6% annual pace, partly on a surge in computer chip shipments for AI investment, and cut nearly 1.7 percentage points from growth.
- Business investment excluding housing grew at a 9% pace in the quarter, a gain the report tied to the AI investment boom.
- A gauge of underlying demand that strips out government spending and trade grew at a 4.6% rate, up from 1.8% in the first quarter.
- The Bureau of Economic Analysis figure is its third estimate for the quarter, revised up from both the advance and second readings.

Why it matters
- exposure A sell-off in AI-linked shares would reach the economy through the consumer, the component carrying most of this quarter's growth, and no import subtraction cushions that line.
- constraint A slowdown in AI chip orders would cut imports along with investment, limiting how much an AI capex pullback subtracts from headline GDP.
- cost Part of what US companies spend on AI becomes output for foreign chipmakers, a leak that helped hold a quarter of 4.6% underlying demand to a 2.2% headline.
Consumer spending is about 70% of US economic activity, so a 3.8% annual pace adds roughly 2.7 percentage points to growth [3][1]. By itself, consumer spending more than covers the 2.2% headline [1][1]. The first-quarter pace was 0.7%, so spending growth accelerated by 3.1 points from one quarter to the next [3][4]. Fortune's report credits part of that to a strong stock market, one that reflects enthusiasm over artificial intelligence and enriches wealthy investors who then have more to spend [4].
Economists had expected the final estimate to leave the earlier 1.5% figure roughly unchanged. It added 0.7 point [2][2]. "The economy is increasingly reliant on AI gains and the corresponding wealth effects boosting higher-income households' spending power to fuel recent growth," said Michael Pearce, chief U.S. economist at Oxford Economics [8]. "The economy remains sensitive to a sudden reversal of optimism on AI," he said [9]. He was describing a risk, and spending in the quarter was still accelerating [3][9]. Neither Fortune's account nor Pearce puts a figure on the wealth effect or splits AI equipment between imported and domestic [4][8].
Chips push the other way in the accounts. GDP counts only domestic production, so imports are subtracted [5]. A foreign-made chip installed in a US data center is counted once in the 9% business-investment line and taken out again in the 1.7-point import drag, so its net contribution to output is close to zero [5][6][3]. The 4.6% underlying rate measures demand before trade is netted out, and imports met part of that demand [7][5].
A cooling in AI could reach these figures by more than one route. If companies cut chip orders, investment and imports fall together, and the headline takes a smaller hit than the investment line alone [3]. If AI stocks fall, the households Fortune describes lose the gains behind their spending, and they sit inside a component worth about 70% of the economy with no import line to offset the drop [3][4]. If neither happens, housing offers a second support: residential investment rose 2.8%, its first increase since the end of 2024, after high mortgage rates depressed the market [10].
I think the exposure runs mainly through stock prices and the consumer, and the chip surge is roughly neutral for measured output [1][3]. The counter-case is that much of the 9% investment pace is domestic spending that no import line cancels. If so, a capex pullback costs more output than the netting suggests [6][3]. The view is wrong if consumer spending holds its pace through a quarter in which AI-linked stocks fall.
What to watch
- The first estimate of third-quarter GDP, due Oct. 29, and whether consumer spending stays near its 3.8% second-quarter pace.
- A decline in AI-linked stocks, and whether higher-income households' spending follows it down, the channel Pearce identified.
- Whether import growth slows from its 12.6% pace as chip shipments ease; slower imports would lift headline GDP even if AI investment cools.
