Mike Dolan: ROI-BIS is not afraid to speak out against the AI bubble.

The world's central bank forum and watchdog have?warned investors against being swept up in this frenzy.

The Basel-based Bank for International Settlements, in its annual report on the?state of world finance? on Sunday did not doubt the AI buildout's scale -- but was concerned about the "hangover" when spending peaks.

As the U.S. and Israel war against?Iran continued to rumble in the background U.S. chipset stocks rallied by 75% in the second quarter of 2026, driven by another wave in capital expenditure forecasts coming from hyperscalers who are racing to build AI infrastructure. This has caused supply bottlenecks, chip shortages, and stoked supply bottlenecks.

This pushed the earnings growth estimate for 2026 in the United States to almost 25%. Forecast AI capital expenditure by the five largest hyperscalers will be approaching $1 trillion this year. Goldman Sachs estimates that the total cumulative amount could reach $7.6 trillion in 2031.

Anyone? For the umpteenth and final time, can anyone confirm that this is a bubble? One of the biggest investors in tech and cheerleaders of that sector says it's not true. SoftBank's Masayoshi son said only last week that thinking such thoughts would offend the gods.

Son: "It is blasphemy to call AI a bubble. "This is just the beginning." "The potential of AI will be unlocked."

He's probably going to say it, given that hundreds of billions are at stake.

Other investors are starting to realize, perhaps a little weary, that the explosion of?spending' and stock prices is not the bubble they feared.

Deutsche Bank's latest quarterly client survey revealed that the perceived bubble risk for the Magnificent Seven Megacap stocks has been the lowest since 2021.

However, for the U.S. technology sector as a whole, these risk perceptions remain as high as they were in the previous two years.

This divergence could explain why June, despite the fact that chipmakers had their best quarter ever, was the worst monthly performance for the Mag 7, since the group was formed three years ago.

As we approach the halfway mark, it is clear that a bearish capitulation has both positive and negative effects.

Share prices may reflect the reality of revenue for many chipmakers.

Micron Technology's stock has more than tripled since March. The revenue estimates are also up, but the 12-month price/earnings has remained virtually unchanged. It is now at eight times its previous level.

Even though a near tripling of the share price for Intel, which is still losing money, stands out as an anomaly, valuations at chipmakers like Broadcom and Qualcomm are historically limited.

AI EATS ITSELF

It is up to the BIS, a financial stability watchdog, to explain what can go wrong in the economy and markets. Maybe they will do the same as SoftBank's son.

The BIS report focused primarily on the risks of sustaining the pace of investments, which was compounded by the race between a small number of firms based on the belief that only those with superior technology would ultimately dominate the market.

The watchdog warned fierce competition may lead companies to invest too much in AI projects with uncertain returns, leaving the entire sector vulnerable if they fail to deliver.

It said that as competition drives capex higher, the sector's total payoff could shrink, or even turn into a negative scenario in adverse scenarios.

"Disappointment with returns could trigger a quick pullback in funding and turn the capex boom in a long-term investment bust. This could have knock-on effects to financial conditions."

The BIS also highlighted supply bottlenecks for power generation, grids of electricity and memory chips. They could also force companies to commit to longer-term contracts in order to secure limited supplies. This would expose them to excessive investment and make them more vulnerable to demand disappointments.

The report's most stern warning is reserved for the possibility that AI will eventually eat itself.

If AI is able to replace human intelligence and work, as its most ardent acolytes claim, then the risk is that income will be diverted away from workers into AI investments. If taken to an extreme, the workers' share of the national income may fall below zero and leave fewer people with purchasing power.

The BIS says that firms who are proactive will eventually stop investing if they anticipate a demand problem.

The demand for further capacity expansion is missing. "The demand bottleneck becomes a binding constraint."

Even if it's blasphemy, a lot of the money spent in this AI arms race still relies on faith.
