Anthropic on Monday unveiled its Form S-1 filing, taking the company one step closer to completing its long-awaited move to the public markets, which is now seen as almost guaranteed to come this year.
Speculators on prediction market platform Kalshi place 95% odds that the artificial intelligence giant officially announces an initial public offering by the end of 2026.
Kalshi defines officially announcing an IPO as either the Securities and Exchange Commission declaring an S-1 effective, a priced IPO or an exchange assigning a ticker to a stock.
The Anthropic S-1 envisions a Nasdaq Stock Market ticker symbol of "ANT."
Anthropic is aiming to start trading the week of Nov. 16, according to a report in the Wall Street Journal. Traders on Kalshi place just a 14% chance that the company begins trading before then.
