Market debut of AI company behind Claude chatbot will be one of largest in US history, a test of its financial viability
Anthropic has publicly filed for a stock market listing, one of the largest debuts in history. The company’s float on the US market is likely to be a high-water mark in the multitrillion-dollar AI boom and a test of its financial viability.
Analysts and investors have valued the San Francisco-based company, founded in 2021, at more than $1.5tn. The company, which will will list under the symbol ANT, confidentially filed with US financial regulators for an initial public offering in June.



Luckily S&P is blocking some of these shenanigans by not allowing inclusion into the S&P500 for companies that are not profitable even if they become publicly listed. This includes all of the AI only companies.
Because so many large investment funds have dumped their money in these AI companies they will still take down the entire stock market when they go bust. There is so much money which does not exist inside of the bubble.
Do you have any articles or more information on the S&P blocking them?

“In a Thursday news release, the index provider announced it was holding firm on all three contested criteria — the one-year waiting period before new listings can qualify, the requirement for demonstrated profitability, and minimum public float thresholds — regardless of how large a company may be. ‘Exceptions to the financial viability, seasoning, and IWF requirements should not be granted solely based on market capitalization,’ the company said. The decision preserves existing methodology without alteration.”
I checked vanguard when spacex floated and they had a good explainer. I didn’t dig deep enough to find it on the S&P documentation, but in this article under 3 things to consider, it mentions S&P requires a company to be profitable in its recent quarter or the sum of its previous 4 quarters https://corporate.vanguard.com/content/corporatesite/us/en/corp/articles/staying-grounded-moonshot-ipos.html
