IPOs to watch for in 2025

1. Stripe

Stripe has been a rumored IPO candidate for a while. The company’s payments processing business for e-commerce has been riding the wave of online shopping, and Stripe has major supporters in the form of venture capital firms Andreesen Horowitz, Kleiner Perkins and Sequoia Capital. The company’s latest valuation is still a far cry from its high-water mark of $95 billion in 2021, and a transaction with Sequoia in 2024 valued the firm at just $70 billion.

2. Databricks

Databricks is a tech unicorn that has the potential to be an IPO valued in the tens of billions, and therefore one of the highest-profile offerings in any year that it goes public. Will that year finally be 2025? The company raised $10 billion in funding in January 2025, valuing the business at $62 billion. That’s up nicely from a 2023 valuation of $43 billion and $31 billion in October 2022. Rivals include Snowflake and Confluent. Databricks has some top investors, including Andreesen Horowitz, BlackRock, Tiger Global and Fidelity.

3. Cerebras Systems

It’s hard to get hotter than semiconductor companies focused on artificial intelligence, and that’s the business of chip company Cerebras, which competes with leaders such as Nvidia. The company filed IPO paperwork in August 2024, though it’s been facing concerns from U.S. regulators about one shareholder-customer that have slowed the process. Cerebras had a valuation of $4 billion as of 2021, a stale valuation, and the company reportedly wants to achieve double that in an IPO. 

4. eToro

The broker eToro offers trading in stocks, options and cryptocurrencies, and it’s now looking to hit the markets itself. The broker tried to go public a few years ago via a SPAC, but had to scrap that deal. The London-based brokerage filed confidential IPO paperwork in February 2025, and the company appears to be targeting a $5 billion valuation, after being valued at $3.5 billion in early 2023. So the broker may hit the market soon, if the market remains amenable. 

5. Chime Financial

Chime offers a financial app that acts like a bank, offering fee-free accounts for customers, and it confidentially filed some IPO paperwork in December, which could tee it up for a 2025 IPO. Chime has been a hit with consumers, and has an estimated 22 million active users as of 2024, according to Cornerstone Advisors. Speculation has been rife for years that Chime would be going public, but it’s still private and looking for the right time to debut. Chime’s high valuation was $25 billion in late 2021, but many tech companies’ valuations plummeted in 2022 and 2023.
