ChatGPT Rockets To 700M Weekly Users Milestone

ChatGPT has exploded to 700 million weekly users while burning through billions in cash, setting up a high-stakes showdown over the future of artificial intelligence.

OpenAI’s ChatGPT reached 700 million weekly active users in August 2025, nearly doubling its user base from 400 million just six months earlier. The meteoric rise comes as the company wrestles with mounting costs and tensions with its biggest backer, Microsoft.

The AI platform’s revenue doubled to $12 billion annually in the first seven months of 2025, generating roughly $1 billion monthly. However, that success masks a troubling reality: growth comes despite a projected $8 billion cash burn for 2025, up from $5 billion the previous year.

“We’re seeing unprecedented adoption, but the economics remain challenging,” said one industry analyst who requested anonymity.

The company’s estimated daily operating costs of $700,000 to run ChatGPT infrastructure alone underscore the financial pressures.

Enterprise Adoption Accelerates

Corporate America can’t get enough of ChatGPT. Business users increased from 3 million in June to 5 million in August 2025, a 67% surge in just two months. The platform has become essential infrastructure for major corporations.

Over 80% of Fortune 500 companies have integrated ChatGPT into their workflows, encompassing a wide range of industries, from financial services to healthcare. Morgan Stanley uses it for wealth management research. Uber tapped it to streamline customer service. Lowe’s deployed it across operations.

The rapid adoption of enterprise solutions reflects a broader shift in the market. Companies that once viewed AI as experimental now see it as mission-critical. They’re embedding ChatGPT into core business processes, from document drafting to code development.

Government Goes All In

Washington has embraced ChatGPT with surprising enthusiasm. ChatGPT Gov was launched in January 2025 for U.S. government agencies, featuring enhanced security features designed to meet federal compliance standards.

The numbers tell the story: Over 90,000 government employees across more than 3,500 agencies using ChatGPT have generated more than 18 million prompts. They’re using it for everything from translating documents to drafting policy memos.

Early adopters include prominent organizations such as the Air Force Research Laboratory and Los Alamos National Laboratory. These agencies aren’t just experimenting—they’re integrating AI into sensitive research and development work.

The government push represents a significant validation for OpenAI. Federal adoption could unlock billions in contracts while establishing ChatGPT as the de facto AI standard for public sector work.

Partnership Tensions Mount

Behind the scenes, trouble’s brewing between OpenAI and Microsoft. Microsoft-OpenAI negotiations have strained over equity stakes and revenue-sharing terms, according to multiple reports.

The current deal gives Microsoft a 20% revenue share through 2030, but OpenAI wants to slash that to 10%. Microsoft, which has invested over $13 billion, wants continued access to OpenAI’s technology beyond 2030. OpenAI seeks greater independence.

The discord goes deeper than money. OpenAI is reportedly considering antitrust complaints against Microsoft over competitive practices. Some OpenAI executives believe Microsoft is using its cloud infrastructure dominance to box in the AI startup.

“It’s like watching a marriage fall apart in slow motion,” said a source familiar with the negotiations. “Both sides need each other, but neither trusts the other anymore.”

Market Competition Heats Up

ChatGPT’s dominance faces growing challenges. The platform maintains a 60.5% market share as of July 2025, down from 76.4% in January 2024. That’s still commanding, but the trend line points down.

Google Gemini holds a 13.5% share, while Microsoft’s own Copilot claims a 14.3% share. Perplexity has carved out a 6.2% market share. However, the real threat might be Claude AI, which is showing 14% quarterly growth by targeting business users with specialized features.

New competitors keep emerging. DeepSeek and others are gaining traction with lower-cost alternatives. Some offer comparable performance at a fraction of the price of ChatGPT, appealing to cost-conscious businesses.

The competitive pressure arrives at an inopportune moment. OpenAI needs to maintain its market lead to justify its massive valuation and ongoing fundraising efforts. But defending that position requires spending even more on infrastructure and development.

Regulatory Scrutiny Intensifies

Washington regulators sense an opportunity. The FTC launched an inquiry into AI partnerships in January 2024, specifically examining the relationship between Microsoft and OpenAI.

The investigation examines whether these partnerships create lock-in effects that deprive startups of resources. Regulators are concerned about AI market concentration and aim to ensure healthy competition.

The Department of Justice and the FTC have divided oversight responsibilities, with the FTC handling matters related to Microsoft and OpenAI. Their focus centers on preventing any single company from dominating the AI ecosystem.

For OpenAI, regulatory pressure adds another layer of complexity to an already complex situation. The company must balance its need for Microsoft’s resources against regulators’ demands for more competitive markets.

Financial Realities Bite

The math remains daunting. Even with $12 billion in annualized revenue, OpenAI’s expenses far exceed its income. Infrastructure costs continue to rise as the number of users increases. Research and development spending shows no signs of slowing.

The company has launched new funding rounds targeting $30 billion, with SoftBank reportedly committing a total of $32 billion. But investors are asking harder questions about the path to profitability.

“Revenue growth is impressive, but it’s being outpaced by cost growth,” noted a venture capital partner involved in AI investments. “At some point, the economics have to make sense.”

The cash burn reflects AI’s fundamental challenge: providing cutting-edge technology requires massive computational resources. Every ChatGPT query costs money. More users mean higher bills.

What’s Next?

OpenAI faces critical decisions in the coming months. It must strike a balance between explosive growth and financial sustainability. The Microsoft relationship needs resolution, one way or another. Competition will only intensify as rivals improve their offerings.

The government adoption provides a bright spot, potentially offering more stable, long-term revenue. But regulatory scrutiny could limit OpenAI’s options for partnerships and expansion.

Success isn’t guaranteed despite the 700 million user milestone. The AI market remains fluid, with technology advancing rapidly and business models still evolving. OpenAI pioneered consumer AI, but maintaining that lead requires navigating treacherous waters.

The following year will likely determine whether OpenAI can transform its user base into a sustainable business or whether it becomes another cautionary tale of growth at any cost.
