Three AI leaders—SpaceX, OpenAI, and Anthropic—are gearing up for major IPOs in the second half of 2026, with SpaceX potentially near a $2 trillion valuation and OpenAI and Anthropic each approaching roughly $1 trillion; collectively the fundraising could exceed $200 billion.

SpaceX recently raised about $65 billion, lifting its valuation toward the trillion-dollar mark and positioning it as a valuation leader in the group.

Anthropic’s confidential IPO filing could place it ahead of OpenAI in valuation, making it the world’s most valuable AI startup if market conditions cooperate.

Anthropic has demonstrated advanced AI capabilities, including the Claude Mythos Preview with cybersecurity features, and has engaged policymakers and industry leaders around its technology.

Investors should watch for lead underwriters, potential strategic partnerships, and forthcoming statements from OpenAI that could influence timing and pricing.

The trio represents distinct layers of the AI ecosystem, offering investors different yet complementary visions of AI value rather than identical business models.

Corporate demand for AI tools that automate coding and business tasks has driven rising demand for Anthropic’s products.

Much of the financial and operational detail remains private due to the confidential draft registration, with fuller disclosures expected later in the process.

Anthropic has filed confidentially for an IPO, signaling a shift toward a public listing and altering the race with OpenAI.

As Anthropic moves forward, OpenAI’s likelihood of being first to market has diminished in light of recent fundraising and regulatory steps.

The broader U.S. AI sector remains highly anticipated, with ongoing competition between Anthropic and OpenAI shaping expectations for public listings.

If all three go public, the IPOs could redefine AI stock dynamics, drawing intense focus on infrastructure, cloud computing, semiconductors, and large language models.
