OpenAI's Revenue Run Rate Tops $40 Billion as IPO Looms

A Doubling in Eight Months

Bloomberg reported on August 13, 2026, that OpenAI’s annualized revenue run rate has officially surpassed $40 billion — nearly doubling its pace from the end of 2025, when the company was generating roughly $20 billion per year. The figure, confirmed by multiple financial outlets including Yahoo Finance, NDTV Profit, and Business Times, represents the fastest revenue scale-up in software history and sends a powerful signal to Wall Street as OpenAI prepares for its initial public offering.

To put the trajectory in perspective: OpenAI generated $3.7 billion in revenue for all of 2024. By mid-2025, it crossed $10 billion annualized. It hit $25 billion in early 2026. And now, just eight months later, that number has climbed past $40 billion. The company is adding roughly $2 billion in new annualized revenue every quarter — a pace that no software company has ever sustained.

What’s Driving the Surge

According to Bloomberg’s reporting, the growth is being fueled by two key engines: the Codex coding agent and ChatGPT Work, the enterprise-focused product tier that OpenAI has been aggressively expanding throughout 2026.

Codex, OpenAI’s AI-powered software development agent, has seen explosive adoption among developers and enterprises. Internal data from OpenAI showed that by mid-2026, Codex usage among the company’s own workers had grown from less than 10% of total token consumption to over 85%. That same pattern is playing out across the broader enterprise market, where companies are deploying Codex to automate large portions of their software development pipelines.

ChatGPT Work, meanwhile, has become the company’s fastest-growing revenue stream. The enterprise product — which offers advanced agent capabilities, workspace-level data controls, and the recently launched Premium tier at $125 per user per month — now accounts for more than 40% of OpenAI’s total revenue. The company recently reported 9 million paying business users, up from 5 million in late 2025.

OpenAI CFO Sarah Friar told employees in late July that the company’s ARR in July alone topped all of Q2 — a remarkable acceleration that set the stage for the $40 billion milestone.

The IPO Imperative

The $40 billion run rate lands at a critical moment for OpenAI. The company confidentially filed its S-1 with the SEC on June 8, 2026, and is widely expected to go public in the fourth quarter of 2026. Its last private funding round, closed in March 2026, valued the company at $852 billion post-money — making it the most valuable private company in the world.

But that valuation, staggering as it is, was set when OpenAI’s run rate was closer to $25 billion. With revenue now surging past $40 billion, investors and analysts are already speculating that OpenAI could command a public market valuation exceeding $1 trillion. That would make it the largest IPO in history, surpassing Saudi Aramco’s $25.6 billion offering.

The timing is not accidental. OpenAI faces mounting competitive pressure from Anthropic, which surpassed it in annualized revenue earlier this year with a run rate approaching $50 billion. The IPO is both a liquidity event for early investors and employees, and a war chest for the infrastructure spending that AI supremacy demands. OpenAI reportedly faces over $1 trillion in committed compute and infrastructure obligations over the coming years.

The Anthropic Shadow

OpenAI’s $40 billion figure is undeniably impressive, but it comes with a caveat that Bloomberg and others have been careful to note: Anthropic has been growing faster. As of mid-2026, Anthropic’s annualized revenue run rate reached approximately $47 billion, and some estimates peg it even higher. The company’s Claude models have dominated the enterprise coding market, and its aggressive infrastructure investments — including a landmark $9.1 billion, 20-year compute deal with Bitcoin miner Riot Platforms — signal that Anthropic intends to maintain its lead.

The competitive dynamic adds urgency to OpenAI’s IPO. Both companies are burning billions on compute, talent, and infrastructure. Access to public markets would give OpenAI a permanent capital advantage — stock-based compensation to retain talent, currency for acquisitions, and the credibility that comes with public market disclosure.

Revenue Composition

Based on analysis from Value Add VC and OpenAI’s own disclosures, the $40 billion run rate breaks down roughly as follows:

• ChatGPT subscriptions (consumer): ~$17–20 billion — monthly subscriptions from the company’s 300+ million weekly active users, including Plus, Pro, and Team tiers
• API consumption: ~$10–12 billion — developer and enterprise API usage, including the increasingly lucrative agent workloads
• Enterprise/Business seats: ~$8–10 billion — ChatGPT Business, Enterprise, and the new Premium tier, serving over 9 million paying business users
• Other revenue: ~$2 billion — including the nascent advertising business, licensing deals, and specialized products like GPT-5.6-Cyber

The enterprise segment is the fastest-growing piece of the pie. Enterprise revenue exceeded 40% of total revenue for the first time in 2026, up from roughly 25% a year earlier. OpenAI’s recent hiring of Dali Rajic — the former Wiz president brought in as Chief Revenue Officer — signals that the company intends to push enterprise even harder.

The Profitability Question

Revenue growth, however, tells only half the story. OpenAI’s cost structure remains daunting. The company is projected to spend roughly $34 billion in 2026 on compute infrastructure alone, with total operating losses potentially exceeding $14 billion for the year. The path to profitability depends on margins improving as model efficiency increases and as higher-margin enterprise and agent revenue replaces lower-margin consumer API traffic.

The IPO prospectus, when it becomes public, will face intense scrutiny on this point. Investors will need to be convinced that OpenAI’s revenue growth will eventually outpace its infrastructure spending — or that the company can continue raising capital indefinitely to fund the deficit.

What Comes Next

The $40 billion run rate is a milestone, but it may be a transitory one. OpenAI is accelerating, and if current growth rates hold, the company could hit $50 billion or more by the time its S-1 goes effective. The launch of new agent products, the expansion of the ChatGPT Work platform, and the broader adoption of Codex all point to continued upward momentum.

For the AI industry as a whole, the figure is a watershed moment. It confirms that generative AI has moved beyond experimental budgets into core enterprise spending. And it sets the stage for what could be the most consequential public market debut in technology history — one that will price not just OpenAI, but the entire AI sector.
