OpenAI: OpenAI is the company that made generative AI a mass-market product. Its ChatGPT assistant launched on November 30, 2022 and became the fastest consumer app to reach 100 million users. Today OpenAI builds frontier models (the GPT series and reasoning models), consumer and workplace products (ChatGPT, Codex, Sora) and an API platform used by millions of developers. Its stated mission is to ensure artificial general intelligence benefits all of humanity. The company is headquartered in San Francisco, California. OpenAI was founded in December 2015 in San Francisco, California, by Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, Wojciech Zaremba, and John Schulman as an open-source non-profit research institute, before restructuring in 2019 to create the premier frontier artificial intelligence company behind ChatGPT, GPT-4, and the o1 reasoning series.

Perplexity AI, Inc.: Perplexity AI is a private San Francisco company best known for its answer engine, which gives cited written answers instead of a page of links. Since 2025 it has expanded into an AI browser (Comet) and an autonomous agent (Computer), and it serves consumers, enterprises and developers through the Sonar API. The company is headquartered in San Francisco, California. Perplexity AI was founded in August 2022 in San Francisco, California, by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski to reinvent internet search into an interactive conversational answer engine with verified inline source citations.

OpenAI and Perplexity AI, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between OpenAI and Perplexity AI, Inc..

OpenAI business model: OpenAI earns revenue in three main ways. First, ChatGPT subscriptions: consumer tiers such as Plus and Pro, plus Business, Enterprise and Edu seats sold to organizations. Second, the API platform, where developers and companies pay per token to build OpenAI models (GPT, reasoning, image, audio and embeddings) into their own software. Third, enterprise and partner deals, including Codex coding agents, custom deployments, and revenue sharing with Microsoft, which resells OpenAI models through Azure. ChatGPT also has a free tier funded by paid users, and OpenAI has been adding commerce and advertising-style formats to monetize free usage.

Perplexity AI, Inc. business model: Perplexity makes money mainly from subscriptions. The free tier is limited. Pro ($20 a month) and Max (a higher tier that includes the Comet browser's advanced features) add more queries and access to frontier models. Enterprise Pro and Enterprise Max are sold per seat to companies and add security controls and search over internal files. Developers pay by usage for the Sonar API. Since February 2026 the Computer agent has added usage-based charges on top of subscriptions. Distribution deals with telecom carriers, device makers such as HP, and payment partners bring in users through bundled plans. Perplexity has also tested ads and run revenue-sharing programs for publishers.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of OpenAI stack up against those of Perplexity AI, Inc..

OpenAI competitive advantage: OpenAI's advantage is distribution plus scale. ChatGPT is the most widely used AI assistant, with OpenAI citing more than 900 million weekly users in February 2026, which gives it a direct consumer channel that rivals have to buy or build. It pairs that with frontier research, a large developer ecosystem on its API, and the ability to raise capital at a scale no other private company has matched, including the $122 billion round closed in March 2026.

Perplexity AI, Inc. competitive advantage: Perplexity's edge is focus and speed of shipping. Every answer shows its sources, which makes results easy to check. Because it is model-agnostic, it can route queries to its own Sonar models or to OpenAI, Anthropic and other providers; a three-year, roughly $750 million Azure agreement with Microsoft signed in January 2026 widened that access (Sacra). Google has a large search-ad business to protect. Perplexity does not, so it can build answer-first and agent products without that conflict.

Future prospects matter as much as current results. The growth strategies below explain how OpenAI and Perplexity AI, Inc. each plan to expand from here.

OpenAI growth strategy: OpenAI is growing on four fronts: selling ChatGPT and Codex into enterprises, turning ChatGPT into a broader 'super app' with agents, shopping and apps inside the chat, building its own compute through the Stargate data center program and chip partnerships, and moving into hardware through the 2025 acquisition of Jony Ive's io. Acquisitions such as Statsig (2025) brought in product and engineering leaders for the applications business.

Perplexity AI, Inc. growth strategy: Perplexity is growing on three fronts: (1) agent products such as Comet and Computer that carry usage-based pricing; (2) distribution through carriers, PC makers and bundles, including the HP preload announced September 15, 2026; and (3) enterprise seats with internal-file search. It is also securing more compute and model access, through the January 2026 Microsoft Azure agreement and the Crusoe GB300 capacity deal.

A closer look at the financial trajectory of OpenAI and Perplexity AI, Inc. rounds out the comparison.

OpenAI: OpenAI reports revenue as annualized run rate rather than audited GAAP figures. The company says it reached $1 billion of revenue within a year of launching ChatGPT, was generating about $1 billion per quarter by the end of 2024, and passed $20 billion of annualized revenue by the end of 2025. Axios reported the run rate was nearing $70 billion at the end of September 2026. Funding has scaled alongside: $110 billion announced in February 2026 at a $730 billion pre-money valuation grew to $122 billion committed at $852 billion post-money by March 31, 2026, anchored by Amazon, Nvidia and SoftBank. An employee tender of about $7 billion followed in August 2026 at the same valuation. The company remains unprofitable because compute spending outpaces revenue.

Perplexity AI, Inc.: Perplexity is private and does not publish audited financials, so revenue figures are third-party estimates. Sacra estimates annualized revenue of about $232 million at the end of 2025 and $750 million in August 2026. The company's valuation rose from $520 million (January 2024) to $3 billion (June 2024), $9 billion (December 2024), $14 billion and then $18 billion (mid-2025), and $20 billion after a $200 million round in September 2025. Reuters, citing The Information, reported on August 23, 2026 that Nvidia was in talks to invest at a valuation above $30 billion. No such deal had been confirmed as of October 1, 2026. Net income has not been disclosed.
