Anthropic's formal marketing campaign for its stock market listing (IPO) — a series of investor meetings known as a roadshow — could begin as early as the week of November 9, 2026. Bloomberg reported this, citing sources familiar with the process. If the schedule holds, the company's shares could begin public trading before Thanksgiving on November 26.
The roadshow is one of the most important stages of an IPO: company management presents the business plan, financials, and growth strategy to large institutional investors. After these meetings, the final share price is set based on investor demand. According to Bloomberg, Anthropic is now approaching this stage, and the plan is being discussed with bankers.
Anthropic has not commented officially so far — during IPOs, companies typically refrain from commenting until official filings are submitted. But if the process stays on schedule, it is expected to become the largest public offering in history.
$100 Billion: Could Be a Record IPO
Prospective investors believe Anthropic's fair value sits in the $1.8–2 trillion range. That valuation would place the company among the world's most valuable private technology companies. During the listing, the company could raise around $100 billion — if that figure is confirmed, the record for the largest IPO in history would be broken.
A $100 billion placement is far above previous records in scale. Such volume is a singular event for the IPO market: even the largest tech listings are usually measured in the tens of billions. That is why the plan is being widely discussed on Wall Street.
At the same time, the final numbers have not yet been set. The valuation range and the size of the placement will be determined during the roadshow based on institutional investor demand. If demand is strong during the roadshow, the price will move toward the upper end; if demand is weak, it could fall lower. So $1.8–2 trillion is the current estimate, not a guaranteed price.
IPO proceeds are usually directed toward the company's growth plans. In artificial intelligence, these funds are mainly spent on computing capacity (data centers), research, and product development. Anthropic's specific plans will be disclosed in official filings.
Timeline: From October 14 to November
According to a separate Bloomberg report, Anthropic will hold an investor day for institutional investors at its San Francisco headquarters on October 14. Investor day is a preparatory event ahead of the roadshow: the company invites major investors to its office to introduce them to the team, technology, and strategy up close. It is seen as the final stage before formal marketing begins.
The next key milestone is the week of November 9. Sources say the roadshow could begin that very week. Calendar considerations also played a role in choosing the date: Thanksgiving falls on November 26, and trading activity on U.S. exchanges drops sharply during the holiday week. Companies usually try not to time major listings to the pre-holiday "dead period." Anthropic therefore aims to start trading before the holiday.
The schedule is still fluid: both the sources and Bloomberg stress that the timing could change. In IPO processes, last-minute date shifts are routine — market conditions, investor demand, and internal readiness all play a role. Still, the listing is expected to be completed by the end of 2026, consistent with earlier plans.
Context: OpenAI Falls Behind in the Race
The Wall Street Journal reports that Anthropic initially considered holding the listing in early autumn but is now considering a November option. The reasons for the change of plans have not been disclosed, but adjusting IPO schedules to market conditions is standard practice.
The newspaper also writes that chief rival OpenAI has pushed its IPO to at least next year. That means that in the "who lists first" race between the two AI giants, Anthropic is pulling ahead. Whoever lists first gets investors' attention and the market's first-mover advantage.
The WSJ piece notes another important point: Wall Street's hopes for a "blockbuster IPO season" in autumn 2026 are fading. Against the backdrop of a number of large listings being delayed or downsized, Anthropic's $100 billion plan could become a special focal point for the market. If the IPO succeeds, it would send a positive signal to other tech companies' listing plans; conversely, weak demand could negatively affect the entire IPO market.

The uncertainty in this quote reflects the nature of IPO processes: dates, valuation, and size remain in flux until the last minute. The week of November 9 is the current plan, not a guarantee. The next concrete news is expected after the October 14 investor day or when official filings are submitted.
