Background

This market asks which companies will officially announce an IPO before the Jan. 1, 2027 resolution date, with each company priced as its own outcome rather than a single winner. Anthropic is the main focus. It publicly filed a Form S-1 on Oct. 26, 2026, amended it on Nov. 2 and again on Nov. 10, and launched its roadshow for a Nasdaq listing under the ticker "ANT," with Goldman Sachs and Morgan Stanley as underwriters. Wonder confidentially filed for a US IPO on Nov. 5.

The market concerns an official IPO announcement, not a guaranteed trading debut, so it can resolve differently from the timing of first trades. Anthropic's registration statement has not yet become effective, and shares cannot be sold until it does. Reported pricing and trading dates are unconfirmed by the company, so a delay, revision or withdrawal is the main risk to the outcome.

Nov. 10, 2026: Will Anthropic IPO This Year? Roadshow Sets $70-$78 Range for Nov. 19

Will Anthropic IPO This Year? Roadshow Launch Pushes Odds to 98%

Anthropic looks very likely to be counted as having announced an IPO this year. On Nov. 10, 2026, it filed an amended S-1 and launched its roadshow, offering 825 million Class A shares at $70 to $78 each for a Nasdaq listing under the ticker "ANT," according to Anthropic and CNBC. On Kalshi, Anthropic's outcome in "Which Companies will officially announce an IPO this year?" rose from 90% to 98% over three days. That market concerns an official IPO announcement, not a guaranteed trading debut, so it can resolve differently from the timing of first trades.

The filing moved the deal from registration to active marketing. Of the 825 million shares, Anthropic is selling 801,351,354 and existing stockholders are selling 23,648,646. Underwriters Goldman Sachs and Morgan Stanley hold a 30-day option on up to 123,750,000 more shares, according to Anthropic. At the top of the range, the offering would raise up to $64.35 billion, and Anthropic is targeting a retail allocation of about 20%, against the typical 5% to 10%, people familiar with the details told CNBC.

Anthropic's Nov. 18 Pricing and Nov. 19 Nasdaq Debut Are the Next Milestones

Anthropic plans to price on Nov. 18 and begin trading on Nov. 19, according to people familiar with the details cited by CNBC. The company has not confirmed either date. Its registration statement has been filed with the SEC but has not yet become effective, and shares cannot be sold until it does.

At 98% on Nov. 10, the remaining 2 points read as execution risk: a postponed pricing, or a withdrawn or revised filing. This market has already shown that sensitivity. It fell to 76% on Nov. 5 before recovering, as CNBC reported. A price set at or near the $70 to $78 range on Nov. 18, followed by a first trade on Nov. 19, would confirm the move. A delay past those dates would test it. Traders can follow the full field of contenders on the which companies will announce an IPO this year market.

The next checkpoints are the Nov. 18 pricing and the Nov. 19 Nasdaq open.
