There’s been plenty of fanfare surrounding Uber and Lyft’s initial public offerings — slated for early 2019 — since the two companies filed confidential IPO paperwork with the U.S. Securities and Exchange Commission in early December. On top of that, public and private investors have had plenty to say about Slack and Pinterest’s rumored 2019 IPOs but those aren’t the only “unicorn” exits we should expect to witness in the year ahead.

Using its proprietary company rating algorithm, data provider CB Insights ranked five billion dollar companies most likely to perform IPOs next year in its latest tech IPO report. The algorithm analyzes non-traditional public signals, including hiring activity, web traffic and mobile app data to make its predictions. These are the startups that topped their list.

Peloton

Peloton, dubbed the “Netflix of fitness,” has raised nearly $1 billion in venture capital funding in the six years since it was founded by John Foley, most recently raising $550 million at a $4 billion valuation. The manufacturer of tech-enabled exercise equipment is more than doubling in size every year and is “weirdly profitable,” an unusual characteristic for a venture-backed business of its age. Headquartered in New York, Peloton doesn’t have any public IPO plans, though Foley recently told The Wall Street Journal that 2019 “makes a lot of sense” for its stock market debut.

Cybersecurity unicorn Cloudflare is likely to transition to the public markets in the first half of 2019 in what is poised to be a strong year for IPOs in the security industry. The web performance and security platform is said to be preparing for an IPO at a potential valuation of more than $3.5 billion after last raising capital in 2015 at a $1.8 billion valuation. Since it was founded in 2009, the San Francisco-based company has raised just north of $250 million in VC funding. CrowdStrike, another security unicorn, is also on track to go public next year and it wouldn’t be surprising to see Illumio and Lookout make the jump to the public markets as well.

Zoom

San Jose-based Zoom Video Communications has reportedly tapped Morgan Stanley to lead its upcoming IPO.

Zoom, a provider of video conferencing services, online meeting and group messaging tools that’s raised $160 million in VC cash to date, is eyeing a multi-billion IPO in 2019 and has reportedly hired Morgan Stanley to lead the offering. Founded in 2011, the company most recently brought in a $100 million Series D financing, entirely funded by Sequoia, at a $1 billion valuation in early 2017. Based in San Jose, Zoom is hoping to garner a valuation significantly larger than $1 billion when it IPOs, according to Reuters.
