If there was any doubt about Wall Street’s enthusiasm for AI, Cerebras answered the bell.

Literally. 

In my latest blog, I break down Cerebras’ blockbuster IPO, what it means for impacted investors on StartEngine Private, and why diversification still matters in fast-moving private markets.

This content is for informational purposes only and does not constitute an offer, solicitation, or recommendation to invest in any securities. Private investments are speculative, illiquid, and involve a high degree of risk, including the potential loss of your entire investment. Past performance is not indicative of future results.

The Largest Public Debut of 2026 (So Far)

On May 14, Cerebras raised $5.6 billion in the largest IPO of 2026 so far.¹ 

And reportedly, shares opened roughly 89% above their listing price, giving the company a $100 billion market cap after its debut.²

That’s a remarkable outcome for the company — and potentially, for our investors as well.

Multiple sold-out offerings on StartEngine priced Cerebras from $25.00 to $102.80 per security. The company ultimately opened at $350 after selling shares at $185.³

Cerebras’ IPO does not imply specific returns for investors with exposure to Cerebras through offerings on StartEngine . Past performance is not indicative of future results. See footnote * below for more details.

Of course, we didn’t launch all of those offerings on a whim.

Cerebras is developing a “new class of supercomputer” to make AI dramatically faster and more efficient at massive scale. With its latest reasoning model, Cerebras claims it’s the only company globally capable of generating output at over 1,000 tokens per second.⁴

A Reminder About Diversification

We won’t know what this IPO means for impacted investors until after a standard lock-up period.

To me, that lock-up isn’t a bug of pre-IPO investing. It’s a reminder of something much bigger.

Successful private market investing is often about patience, consistency, and diversification over time, not chasing a single headline.

Our team spends a significant amount of time searching for pre-IPO opportunities. We look for businesses we believe are building toward meaningful outcomes in large and growing markets.

But while we trust our analysis, we don’t have a crystal ball.

As we’ve seen time and time again, the private markets are fickle. From investing trends to tech innovations to macroeconomic factors, no one can predict what might come next.

An Example From the AI Search Wars

And in AI especially, things have been moving incredibly fast.

The AI search wars look to be much more competitive, as OpenAI and Anthropic vie for dominance in the space.

According to the RampAI Index, more businesses reportedly used Anthropic than OpenAI for the first time in March 2026⁵

That’s a pretty notable development considering OpenAI’s first-mover advantage and dominant consumer brand recognition.

Of course, OpenAI isn’t going anywhere. ChatGPT is still by far the most popular AI chatbot in the world, with around 8 times more monthly visits than its next closest competitor.⁶

And while Anthropic may have seen enterprise traction in March, OpenAI made its own headlines by closing “Silicon Valley’s largest-ever funding round” in March 2026, with $122 million committed by names like Amazon, Nvidia, and SoftBank.⁷

In other words: the competition between these two heavyweights is far from over, and neither is the broader opportunities across AI — from software and hardware to agents and beyond.

Ready to Start or Grow Your Pre-IPO Portfolio?

That’s exactly why I believe building a broad pre-IPO portfolio matters.

Not just across companies, but across stages, sectors, geographies, and time horizons

Because the reality is, nobody consistently predicts every winner. The goal isn’t perfection. The goal is thoughtful exposure to innovation over the long term.

That’s the approach we continue to believe in at StartEngine. Want to join us?

Important Disclosures

This article may contain forward‑looking statements and projections. These are not guarantees; actual outcomes may differ materially.

Investing in private, pre‑IPO companies is highly speculative and illiquid. Such investments are intended only for accredited investors who can bear the risk of total loss. Past performance does not guarantee future results. Consult a financial advisor before investing.

Review our Form CRS and Reg BI disclosure to understand our services and conflicts.

*. The companies listed on StartEngine Private are not involved in or endorsing these investments, and have not approved StartEngine Private LLC or its affiliates.

Rather, when you invest through StartEngine Private, you are buying an interest in a separate Series of StartEngine Private LLC, not stock directly in the companies listed. The Series may hold shares directly or through a special-purpose vehicle (SPV). Your interests may differ from the companies’ stock in both rights and value, and there may not be a one-to-one economic parity between the value of Series interests and the underlying shares. The Series also bears its own costs (such as transaction and administrative expenses), which may reduce investor returns.

These offerings are made under Regulation D, Rule 506(c), through StartEngine Primary LLC (member FINRA/SIPC), and are available only to accredited investors. These investments are speculative, illiquid, and high risk, and you should be prepared to hold them indefinitely and to bear the risk of losing your entire investment.
