Gareth Soloway argues the market is being driven almost entirely by the AI trade, which he says has become bubble-like relative to total U.S. market cap. He is cautious near key technical levels in the S&P 500, Nasdaq 100, and 10-year yield, while seeing short-term tradeable opportunities in some AI names and selective weakness in Bitcoin, silver, and gold.

Gareth Soloway’s core message is that the U.S. market is extremely concentrated in AI stocks and that this concentration is now a warning sign, even if it does not mean an immediate top. He says the top 25 AI-related U.S.-listed stocks now represent about 41.6% of total U.S. market cap, above his cited estimate of the dot-com peak near 37%, and he frames that as evidence of a bubble-like condition. His tone is not outright bearish in the near term; instead, he argues for caution because the market has become heavily dependent on a small set of names. He supports that view with a sequence of technical and market-structure observations. On the S&P 500, he watches a key trend line from the prior pullback and says a break there could lead to multiple down days in a row, which has been rare during the rally. …
Tactically, the market is extended and concentration-heavy, so near-term pullbacks or failed gap-ups in the big AI names could matter more than the index headline. Watch the S&P trend line, Nasdaq resistance, and 10-year yield at 4.5% for the first signs of stress.
Over the next several weeks, the base case is that AI leadership can persist if earnings and capex enthusiasm hold, but breadth should remain weak and any break in the major trend lines could turn into a broader correction. Confirmation comes from whether Nvidia and the other mega-cap AI names keep absorbing flows.
Structurally, the market appears unusually dependent on a small AI cohort, which makes the regime powerful but brittle. If capex growth or narrative support fades, the unwind could be outsized because so much index performance is now concentrated in one theme.
The top 25 AI U.S.-listed stocks now account for about 41.6% of total U.S. market cap, above the speaker’s estimate of the dot-com peak near 37%.
This is the central quantitative argument used to support the bubble-warning thesis.
The market is not ready to punish the AI trade yet, but concentration is high enough to be a warning sign rather than a definitive top signal.
He explicitly says the bubble may continue and that investors should be more careful, not that a burst is imminent.
A break of the S&P 500 trend line could lead to multiple down days in a row, which has been rare during the rally.
This is his near-term technical risk case for the index.
