The American stock market is returning to valuation levels reminiscent of the last days of the internet bubble. Driven by artificial intelligence and the rise of technological giants, the American stock market is setting new records while comparisons with the year 2000 resurface. Between real growth and speculative excitement, the market is now fueling an increasingly tense debate among investors.

In brief
- US market valuations are approaching levels observed during the 2000 internet bubble.
- Artificial intelligence and semiconductors are fueling a sharp rise in technology stocks on Wall Street.
- Several investors believe that the Nasdaq is entering a phase of overheating comparable to that of the dot-com era.
- However, some analysts point out that today's tech giants generate solid profits, unlike the companies of 2000.
The US stock market returns to internet bubble valuations
Several US market valuation indicators are now approaching the peaks observed during the dot-com bubble explosion in 2000, while the S&P 500 has just reached a new record. Indeed, the current rise is largely fueled by companies linked to artificial intelligence and semiconductors.
The Nasdaq continues to set records while a few technological giants concentrate most of the flows. Historic companies like Cisco or Intel are also benefiting from this renewed interest in AI, in a context where investors are massively seeking companies exposed to global technological infrastructure.
Several investors estimate than the American market “is approaching the valuation levels reached at the peak of the internet bubble”a parallel that is starting to come back insistently in trading rooms.
The main overheating signals mentioned in market analyzes are as follows:
- US market valuations are approaching levels observed before the bursting of the dot-com bubble;
- A handful of technology stocks now dominate the performance of the S&P 500 and the Nasdaq;
- Semiconductor-related companies are directly benefiting from the explosion in spending on artificial intelligence;
- Emblematic groups of the dot-com era such as Cisco or Intel are finding stock market trajectories comparable to those of the late 1990s;
- Investor flows remain overwhelmingly focused on companies exposed to AI and digital infrastructure.
Why do some analysts still refuse to talk about a bubble?
Despite these increasingly frequent comparisons with the year 2000, several market players, thanks to on-chain data, consider that the current situation differs profoundly from that of the internet bubble. At the time, a large portion of technology companies were posting massive losses without a viable business model.
Today, leaders in artificial intelligence already generate considerable revenues and have colossal cash reserves. Microsoft, Alphabet or Nvidia rely on profitable activities and tangible industrial demand linked to computing power needs. Some US stock market strategists believe that AI represents a real economic transformation and not a simple speculative narrative. Thus, the market is supported by concrete investments in global digital infrastructure.
This more optimistic reading is also based on the ability of technology giants to quickly transform advances in artificial intelligence into commercial revenues. Markets now monitor less promises than execution capabilities and actual profit growth.
The debate, however, remains open. Several observers point out that excessive concentration of performance on a few companies can weaken the entire market if growth slows suddenly.
The evolution of this technological euphoria now goes beyond the simple framework of American stocks. The crypto market also closely follows investors' appetite for risk, particularly when Wall Street, even if it only enriches a minority, enters a phase of accelerated expansion. A continuation of this dynamic could continue to support speculative assets. Conversely, a sudden reversal in technology stocks linked to AI could fuel a wave of volatility well beyond the Nasdaq.
