Anthropic Files S-1 Opening The IPO Floodgates, Analyst Says

Anthropic, a leading contender in the generative AI race, has confidentially submitted its Form S-1 to the SEC, firing the starting pistol on what Wedbush analyst Dan Ives dubs an "opening of the floodgates" for the long-dormant IPO market. This move not only puts the Claude AI developer on an immediate path to a public offering but also ignites a fierce sprint against rivals like OpenAI and SpaceX, who are also set to test public investor appetite in 2026. The timing couldn't be more critical. Following years of IPO drought, the prospect of three hyper-growth, frontier technology companies hitting the market within months marks a seismic shift for Wall Street. Anthropic, fresh off a staggering $65 billion Series H funding round that underscored immense private market confidence, aims to capitalize on soaring investor interest in AI before OpenAI — rumored to be preparing its own confidential filing — can steal its thunder. Meanwhile, SpaceX, having filed its S-1 on May 20, is already on its roadshow, setting early benchmarks for valuation expectations. While the S-1 filing is a crucial first step, the actual IPO date remains contingent on SEC review, prevailing market conditions, and investor sentiment. Analysts will scrutinize Anthropic financials and growth prospects during its upcoming roadshow, watching closely for how institutional investors value its proprietary AI foundational models against the backdrop of an intensely competitive sector. The success of these initial AI and space-tech listings will likely dictate the pace and volume of other high-profile tech debuts throughout late 2026 and into 2027.
