SpaceX and Anthropic: The most exciting IPOs ever?

Key takeaways

• SpaceX and Anthropic reflect two highly-awaited IPOs.
• SpaceX will debut much sooner than Anthropic, though both are expected to reflect massive market moments.

IPO activity post-pandemic has fluctuated significantly, primarily driven by economic uncertainty, rising interest rates, and inflation, all of which have impacted investor sentiment.

But the tide has shifted in a positive direction over the past few years, with 2026’s lineup, which includes SpaceX and Anthropic, likely the most exciting year we’ve seen in decades concerning debuts. Let’s take a closer look at some of the details surrounding the companies.

Anthropic

Anthropic has officially submitted its confidential draft S-1 prospectus with the SEC, setting up one of the largest tech IPOs in history. The company is expected to target a valuation clearing $1 trillion, building on the momentum of a massive Series H funding round that valued it at $965 billion.

The public listing is anticipated to potentially come as early as this fall, likely reflecting the biggest market story of the back half of 2026. The company's enterprise-focused AI ecosystem is its primary growth engine, with annualized revenue skyrocketing to a staggering $47 billion.

Notably, Anthropic is solidifying its position as a dominant force in corporate AI and critical infrastructure. Driven by the commercial success of enterprise tools like Claude Code, the company is scaling aggressively. To sustain this explosive compute demand, Anthropic has also secured a massive $15 billion-a-year data center lease with SpaceX alongside cloud partnerships with Amazon and Google.

SpaceX

SpaceX has officially filed its public S-1 prospectus with the SEC, setting the stage for the largest IPO in stock market history. Trading under the ticker SPCX, the company is targeting a historic valuation between $1.75 trillion and $2 trillion and aims to raise up to $75 billion in capital.

The public debut could happen as early as June 12^th, so definitely expect it to remain one of the hottest market stories in the near-term. The company's Starlink satellite internet segment is its primary profit engine, with over 10 million subscribers.

Notably, SpaceX is aggressively transforming into an AI and infrastructure giant. After absorbing Elon Musk’s AI startup xAI in a stock-based deal earlier this year, SpaceX spent a staggering $12.7 billion on AI infrastructure in 2025 alone. It is also partnering with Tesla (TSLA - Free Report) on a chip-making project called ‘Terafab’ to build its own AI hardware.
