The race to go public just got real. Anthropic, the San Francisco-based company behind the Claude AI model, confidentially submitted its IPO paperwork to the US Securities and Exchange Commission on June 1, 2026, a full week before its bigger rival, OpenAI, followed suit on June 8. That one-week gap is small by calendar standards but massive in symbolic terms. In the AI industry’s most competitive year yet, being first to the filing window matters.
What Filing Confidentially Actually Means
Let us be clear about something many people miss: a confidential S-1 filing is not an IPO. It is the opening move. It starts the SEC’s review clock and gives Anthropic the option to list publicly once regulators are done reviewing its finances. The actual number of shares and listing price have not been set. Anthropic is targeting a possible debut as early as October 2026, with fall 2026 as the working window. But markets can shift, conditions can change, and the SEC will take its time.
What the filing does confirm is that Anthropic has engaged the law firm Wilson Sonsini (the same firm that managed Google’s 2004 IPO, alongside Morgan Stanley and Goldman Sachs as lead underwriters. That is a serious team assembled for a serious play.
The Numbers That Are Turning Heads
The financial story behind this filing is difficult to ignore. Anthropic’s revenue run rate reached $47 billion as of late May 2026, up from $9 billion at the end of 2025, in a growth driven primarily by enterprise adoption and its Claude Code product. That kind of trajectory in under six months is the sort of number that makes investors forget about valuation concerns entirely.
Anthropic led global LLM revenue share in Q1 2026 with 31.4%, narrowly ahead of OpenAI at 29%. Think about that for a second. The company that most people considered the underdog has quietly overtaken the company that started the whole ChatGPT conversation.
Approximately 80% of Anthropic’s revenue comes from enterprise customers, compared with roughly 40% for OpenAI. That enterprise-heavy model is actually attractive to public market investors, because it signals stable, contract-based revenue rather than volatile consumer subscriptions.
On valuation, Anthropic’s latest funding round raised $65 billion and valued the company at $965 billion. The IPO is expected to price near or above the $1 trillion mark. Anthropic also projects breaking even by 2028, two years ahead of OpenAI’s 2030 profitability target. That gap matters to institutional investors who are tired of funding companies that cannot tell them when they will stop burning cash.
Why the Gulf Should Pay Attention
This is not just a Silicon Valley story. The Middle East has skin in this game, and quite a lot of it.
UAE-based AI investor MGX participated in Anthropic’s $65 billion Series H funding round ahead of the company’s IPO. Qatar’s sovereign wealth fund, the Qatar Investment Authority (QIA), also participated and has backed Anthropic across multiple funding rounds since 2025. These investments make Gulf investors, particularly from the UAE and Qatar, significant stakeholders in Anthropic’s planned public market debut.
The region is essentially holding chips on both sides of the table. OpenAI is a central partner of the UAE’s G42 in the Stargate UAE project, which targets a 1 gigawatt AI data centre in the country. Gulf governments are not picking winners; they are making sure they back all of them.
OpenAI’s Complications Are Anthropic’s Opportunity
OpenAI is not standing still. It has Goldman Sachs and Morgan Stanley working toward its own IPO. But the company carries baggage that Anthropic does not. OpenAI faces ongoing legal matters, including an Elon Musk-related appeal, and has encountered internal caution about public-company readiness. Prediction markets currently place an 82.5% probability on Anthropic listing before OpenAI does.
The AI IPO race of 2026 is shaping up to be one of the defining capital markets stories of the decade. For the Gulf, years of strategic investments in leading AI companies are beginning to converge on the public markets. Whether the first breakthrough comes from Anthropic, OpenAI or another contender, the region has already secured a seat at the table for one of technology’s most consequential wealth-creation cycles.
