Anthropic IPO: What Investors Need to Know About the Claude AI Public Offering
The short answer
Anthropic's IPO could raise up to 100 billion dollars, potentially the largest in history, with a first SEC filing rumored for September 8, 2026. Energy is the best-performing S&P 500 sector in 2026, up 43.5% year-to-date, yet still under 3.5% of the index. SB Energy, a SoftBank-backed data center firm, also filed to go public.

S&P 500 Flat Amid September Uncertainty
The S&P 500 traded flat on the day, with a soft jobs number, Middle East uncertainty, and September seasonality all contributing to a choppy but directionless market. The Nasdaq and semiconductor group (SMH) showed some shakiness, while the S&P 500 held near all-time highs. Steve frames the current environment as one with genuine risks in both directions: an Nvidia earnings surprise could push the market meaningfully higher, while semiconductor weakness could pull it lower. Steve covers the market landscape at (1:00).
Elevated interest rates are one of several crosscurrents investors are weighing right now, particularly for anyone drawing retirement income from bonds.
Energy: The Best-Performing Sector of 2026
The energy sector is up 43.5% year-to-date and hit a fresh all-time high. The structural tailwinds, energy demand and reserve stories, remain intact. Despite the rally, energy still represents less than 3.5% of the S&P 500, meaning most investors do not hold significant energy exposure. Steve highlights a historical example: buying Exxon Mobil at $30 per share during the COVID crash would have yielded a 9% starting dividend that compounds to roughly 14% on the original cost today, with the stock price rising from $30 to $160. The lesson is that buying unloved assets at the right price can be highly rewarding, but timing matters. Steve covers the energy sector at (2:35).

Anthropic IPO: Potentially the Largest in History
Anthropic, the maker of the Claude AI model, is expected to file its first public SEC filing on September 8, 2026, according to IPO Buzz. The IPO could raise up to $100 billion, which would surpass SpaceX's record $86 billion raise and make it the largest IPO in history. Anthropic has already raised $130 billion in private funding and may seek an additional $100 billion in the public offering. The company has also floated the idea of a longer-than-standard lockup period for insiders. Steve discusses the Anthropic IPO at (6:20).
Steve's take on Anthropic and Claude: the consensus is that Claude has been the best-performing AI model over recent months. However, he struggles with the idea that the AI model leaderboard changes every few months, creating switching costs for businesses that integrate these models. The technology is legitimate and Anthropic is a leader, but whether any single model has iPhone-level staying power remains an open question.
How much exposure, if any, a single AI investment like this deserves in a diversified portfolio is a question worth asking before any IPO prices, rather than after.
SB Energy: SoftBank's Data Center IPO
SB Energy, a SoftBank-backed data center power infrastructure company, filed to go public on August 31, 2026. The company is developing gigawatt-scale data center facilities to serve AI compute demand. Notably, SB Energy has no data center capacity currently in operation, reported a $7 billion net loss on $270 million in revenue over the last 12 months, and is heavily dependent on OpenAI as a customer. Nvidia has committed to buying $1.5 billion in SB Energy's non-voting equity at the IPO price, adding another layer to the circular financing pattern in the AI infrastructure space. Steve covers SB Energy at (9:25).
