Cerebras’ (CBRS) IPO is the perfect example of how rushing to own the latest “hot” stock can make you a financial victim in just a matter of days… or even hours.
With three historic initial public offerings coming soon from SpaceX, Anthropic, and OpenAI, I fear that the stock market has entered its most dangerous phase yet: the era of emotional price discovery.

For over a year, the private markets have operated as a hyperinflated echo chamber, bidding up anything with an artificial intelligence or advanced tech narrative to eye-watering valuations. Now that these massive entities are finally migrating to public exchanges, we are witnessing a highly predictable structural pattern. The deal prices with immense hype, explodes on day one, and immediately begins to rot under the weight of real-world technical gravity.
Cerebras, the wafer-scale chipmaker that debuted two weeks ago, was heralded as a paradigm-shifting success. It priced at $185, opened at a wild and crazy $350, and finished its first session at $311 — giving a company with $510 million in 2025 revenue a temporary, staggering market capitalization of $95 billion.
So why is it sitting more than 30% lower, under $250 a share, for an annualized return that would be rated-R if it were a movie? The answer is pure math. A trailing price-sales ratio of 186x leaves absolutely zero margin for error.
Cerebras is not an isolated incident; it is simply duplicating a well-worn playbook established by two other heavily hyped, high-profile mega-listings that peaked within minutes of their debut:
Figma (FIG)
When the design and collaboration software giant finally came to market after its broken Adobe (ADBE) merger, it was treated as a mandatory, institutional “must-own” asset. The stock enjoyed a massive day-one pop, but the peak was printed almost immediately. Once public analysts began scrutinizing its slowing net revenue retention and the severe capital required to defend its moat against generative AI competitors, the stock rolled over.
Bullish (BLSH)
The crypto exchange made an absolute splash when it hit the New York Stock Exchange in August 2025. Priced at an initial $37, it instantly skyrocketed to over $115 per share on day one due to immense hype surrounding institutional crypto adoption and backing from big names like Peter Thiel.
