About Lambda

Lambda is a GPU cloud services and hardware company that supports the training and deployment of artificial intelligence models.

It was founded in 2012 by Stephen Balaban and his team, who initially focused on facial recognition before pivoting toward deep learning infrastructure.

Today, Lambda offers GPU cloud instances, on-premise servers, and workstations optimized for AI workloads.

Its flagship Lambda Cloud competes directly with AWS, CoreWeave, Google Cloud, and Azure in providing GPU compute power, while its hardware line serves enterprises, researchers, and government labs.

The company is headquartered in San Francisco, California.

Lambda has carved out a niche by concentrating solely on GPU computing, setting itself apart from cloud providers with broader offerings. With AI infrastructure as its core focus, the company is positioning itself to capitalize on the rapid growth in model training and deployment needs.

Ownership

Lambda is a venture-based startup. Owners include founders, employees, and a large pool of venture capital firms and individual investors.

Venture capital investors include 1517 Fund, Gradient Ventures, Bloomberg Beta, Razer, Mercato Partners,  US Innovative Technology Fund (USIT) B Capital, SK Telecom, T. Rowe Price, ARK Invest, Fincadia Advisors, G Squared, In-Q-Tel (IQT), KHK & Partners, NVIDIA, Pegatron, Wistron and Wiwynn, and Supermicro.

Individual investors named in company blog posts include Scott McNealy, Austin Russell, Georges Harik, James Hong, James Cham, Jun Hong Heng, Nicolas Pinto, Gary Bradski, Ken Patchett, Randy Ching, Keller Rinaudo (Zipline), Adam D’Angelo, Jeff Hammerbacher, Greg Brockman (OpenAI), Lukas Biewald, Georges Harik, and Garry Tan (Y Combinator).

Valuation

The last confirmed Lambda valuation is $2.5 billion based on the Series D funding round that closed in February 2025. 

However, an August 2025 report indicated Lambda is raising a new round of funds at a $4-$5 billion valuation. 

Pre-IPO platforms Caplight and Hiive estimate the value at above $5 billion as of September 2025.

IPO Potential

The Lambda IPO date is unknown. However, a report from The Information disclosed that the company has hired investment banks and could IPO as soon as the first half of 2026. 

An August 14th Bloomberg report suggested the Lambda IPO could happen by the end of 2025.

Lambda competes with CoreWeave, an AI GPU cloud provider that IPO’d in early 2025. Though much smaller as of writing, Lambda is likely positioning itself to benefit from the market enthusiasm for its type of business.

How to Invest in Lambda Stock

Lambda pre-IPO stock has been available on multiple investing platforms over the past year, indicating some liquidation from early employees and investors. 

Now that Lambda is reportedly moving toward an IPO, time may be running out to participate in pre-IPO funding rounds or equity acquisition. 

Aspiring shareholders can increase their chances of investing in Lambda shares by taking the actions outlined below.

1. Monitor pre-IPO investing platforms for Lambda equity

Accredited investors can monitor pre-IPO secondary marketplaces for share availability. 

Prominent platforms include Hiive, Augment, Forge Global, Nasdaq Private Markets, and EquityZen. 

Investment minimums on these platforms range from $10,000 to $50,000 or more. 

Direct private stock investment and through special purpose vehicles (SPVs) require that investors be accredited. 

Non-accredited retail investors can invest in pre-IPO companies via venture capital funds such as the Fundrise Innovation Fund.

However, Lambda stock is not currently present in the portfolio. Monitor my Fundrise Innovation Fund review for the latest additions to the fund.

2. Participate in the Lambda IPO through a broker 

Lambda has not filed for an IPO publicly or confidentially as of Q3 2025. But a deal could come within the next 12 months if the broader market remains stable. 

When the company files, retail investors can prepare to invest in the IPO by opening accounts with the following online brokers and watching for IPO opportunities. 

• TradeStation
• Robinhood

Access IPOs monitors growing startups and helps investors gain access to IPO shares. High-demand IPOs can provide opportunities for short-term gains.

3. Invest after the IPO

Investing in a company after it goes public instead of while it is still private can offer several advantages. Here are three key benefits: 

• Increased Transparency and Regulatory Scrutiny — Public companies are subject to compliance and reporting standards, which require them to disclose detailed financial and operational information. This transparency minimizes the likelihood of investment decisions being made based on incomplete or deceptive data, thereby protecting investors.
• Improved Liquidity and Accessibility — Unlike private investments, shares of publicly traded companies are bought and sold on stock exchanges, offering investors greater liquidity. This accessibility allows individuals to adjust their portfolios in response to changing market conditions or personal financial goals, often with reduced transaction costs.
• Market-Based Valuation and Credibility — The IPO process serves as a rigorous validation of a company’s worth and business model. Through due diligence and collaboration with lead and secondary bookrunners, a company’s shares are introduced to institutional investors, who help determine an initial market price. This process establishes a credible, market-driven valuation, giving individual investors a reliable benchmark for assessing the company’s value.

Though investors may lack the patience to invest in innovative companies, stock prices often fall after the IPO, presenting excellent opportunities for long-term buy-and-hold investors. 

One of the primary challenges of IPO investors is determining if IPO participation is worth it, or whether we are better off waiting for the stock to fall below its IPO price, which may or may not happen. 

Frequently Asked Questions (FAQs)

Is Lambda publicly traded?

No. Lambda is not publicly traded.

What is the Lambda stock symbol?

Lambda remains a private company, so there is no stock symbol yet. We won’t know the Lambda ticker symbol until it files for an IPO via an S-1 SEC filing. 

Until then, we can speculate. Here are a few potential Lambda stock symbols that are currently available. 

• LAMB
• LAMD
• LMDA

What is the Lambda stock price?

A public Lambda stock price does not exist because the company remains private.

The February 2025 Series D funding round took place at $18.01 per share. With an increased valuation, the price is likely much higher as of Q3 2025. 

Where is the Lambda S-1 Filing?

Lambda has not yet submitted an S-1 filing to the SEC to kick off the IPO process. When it does, we’ll post it here. 

The company will likely file confidentially before releasing documentation to the public. That process allows the SEC to comment on the filing for amendments.

Conclusion

Lambda’s potential upcoming IPO highlights the growing demand for specialized infrastructure to support AI model training and deployment.

Unlike diversified cloud providers, Lambda concentrates entirely on GPU-based computing, a strategy that resonates strongly as AI workloads scale beyond the reach of general-purpose systems.

CoreWeave’s first-mover public markets surge spotlights investor enthusiasm for AI startups. 

For pre-IPO investors, the narrowing window to access shares reflects both the company’s momentum and the eagerness of institutions preparing for a public debut while the IPO window is open.
