Perplexity AI, the AI-powered search engine startup founded by Aravind Srinivas, Andy Konwinski, Denis Yarats, and Johnny Ho in 2022, is reportedly in preliminary discussions to secure up to $1.5 billion in a new investment round that could value the company at $18 billion. This potential funding would double the company’s previous valuation of $9 billion from December 2024, a leap for a startup valued at just $1 billion in April 2024.
With annual recurring revenue reaching £100 million, this latest valuation would represent a revenue multiple of 180x — far exceeding industry benchmarks for AI startups (21.8x–40.6x) and traditional SaaS companies (7.8x). This represents a 34x valuation increase in roughly 14 months—unprecedented even by AI unicorn standards.
For context, this growth rate outpaces other successful AI companies: Anthropic anticipates a £30–40 billion valuation with a projected £1 billion in revenue for 2024 (30–40x multiple), while OpenAI is raising at a £150 billion valuation (approximately 43x its revenue).
From millions to billions in months
Perplexity’s funding history showcases one of the fastest valuation trajectories in recent startup history. In January 2024, the company raised $73.6 million in a Series B round led by IVP, with participation from Nvidia, Jeff Bezos (through Bezos Expeditions Fund), and others at a $520 million valuation. This built upon their earlier fundraising, bringing their total capital to $100 million.
By March 2024, the company secured $63 million more in funding, reaching a $1.04 billion valuation and achieving unicorn status. This doubled its valuation in just three months, with investment led by Daniel Gross, former head of AI at Y Combinator, alongside Jeff Bezos, NVIDIA, Stan Druckenmiller, Tobi Lutke, and Garry Tan.
The momentum continued in April 2024, when Perplexity sought at least $250 million more at a valuation between $2.5 billion and $3 billion. This round included participation from previous investors NEA and IVP, among others. By November 2024, Perplexity had secured a $500 million funding round at a $9 billion valuation, tripling its value from just months prior. This marked the company’s fourth funding round in 2024 alone.
Now, Perplexity is in preliminary discussions to secure up to $1 billion in a new investment round at an $18 billion valuation. If successful, this would double the company’s valuation again in months.
Various elements contribute to Perplexity’s ongoing fundraising efforts. Insiders mention that AI service computing costs are high, with one remark, “computing is costly, so they might need to raise funds” for this reason. Moreover, investors are keen to capitalise on what one referred to as a “zeitgeist moment” for the startup. An existing investor’s partner noted, “They are experiencing very rapid growth” and showed interest in further funding participation.
Search engine development and AI Integration
The AI search sector has intensified, with traditional search leaders and AI companies entering the space. In March 2025, Google launched a limited test of AI Mode, a chat-based AI search engine, while Anthropic added web search to its consumer AI assistant.
Perplexity’s unique approach combines traditional search with AI-generated responses. Unlike Google’s list of links, Perplexity creates narrative answers with linked citations, offering a more integrated search experience.
As Perplexity seeks its potential $1 billion funding round, it’s diversifying its offerings and exploring new revenue streams. The company plans to launch an “agentic” browser, Comet, expanding beyond core search functionality. The company has also strengthened its enterprise solutions with AI search capabilities for internal document access. Additionally, Perplexity is exploring advertising integration as a revenue stream, though it’s still testing various approaches.
A potential TikTok merger
In January 2025, Perplexity proposed a bold merger with TikTok’s U.S. operations. The proposal, revised on January 26 following Trump administration feedback, would create a new U.S. holding company (“NewCo”) combining both businesses.
The revised proposal includes significant IPO terms: the U.S. government could receive up to 50% ownership (without voting rights) post-IPO, valuing the combined entity at a minimum of $300 billion. This path would represent more than 16 times Perplexity’s current prospective valuation and could accelerate its public market timeline.
ByteDance would keep TikTok’s core recommendation algorithm but transfer TikTok US to the new entity for equity stakes. While ByteDance hasn’t formally responded, Trump has temporarily reinstated TikTok and expressed optimism about a deal.
IPO can be as early as 2026
While Perplexity AI hasn’t confirmed IPO plans, its rapid valuation growth and substantial funding have sparked speculation. Industry experts suggest a potential IPO between 2026 and 2027 once it reaches key benchmarks like $250M ARR and establishes strong financials.
The potential $1 billion round at an $18 billion valuation would give Perplexity ample runway to scale without immediate IPO pressure while establishing it as a significant AI search competitor. Though an IPO seems 12–18 months away based on current metrics, the company’s growth trajectory and strategic options, mainly the TikTok merger, could reshape this timeline.
A successful funding round would cement Perplexity’s position among the most valuable AI startups globally. It would provide resources to compete with established search leaders while creating multiple paths to public markets. Though traditional metrics point to a 2026–2027 IPO window, the company’s extraordinary growth and strategic alternatives could accelerate this timeline as AI search evolves.
