Its silly to talk about a bubble when all of the major AI companies just recieved 3-5yrs runway in VC. I normally hate the term FUD, bit in this case it's proveably true. Even if these companies collapse in 5 years, thats a lifetime away in tech years, not an immediate bubble.
I don't think it's particularly silly when the rest of the economy is by all indications in a deep recession. If the tech market is literally the only thing holding up the market then you have to ask how and why.
We're at a record number of subprime borrowers falling behind on car loans, which historically is a really bad economical sign, consumer sentiment is at an all time low and the labor market isn't looking great either. Anecdotally, prices have risen sharply and people are getting sharply priced out of basic necessities due to rising costs.
The subprime loan data can be seen here [1] and consumer sentiment here [2]. Job losses are much harder to estimate given that the current admin is actively refusing to post job numbers (for perhaps, obvious reasons) but we've seen other sites estimate that we're seeing record layoffs [3]. And that's before we get into stuff like tariff policy or the hidden costs of throwing a lot of government employees into unemployment.
The last financial crisis was 2008. Are you saying there was a tech bubble in 2008? The economy can do bad in lots of sectors while others are gaining traction.
S&P500 isn’t “the economy” but in the context of talk of a bubble it seems like we’re talking about equities not the whole economy. So let’s just keep taking the short cut …
The top is over performing so concentration is real but it’s not the only growth driver:
True or not true hard to say without better definitions of terms but seems like current profile is not ultra common in history but it’s not a bunch of losers getting diluted out.
