OpenAI’s ChatGPT is set to reach an impressive milestone of 700 million weekly active users this week, as announced by the company on Monday. This achievement solidifies its standing as one of the most rapidly adopted software products in history, coinciding with the company's preparation to unveil its most advanced language model to date.

This remarkable increase represents a 40% rise from the 500 million weekly users recorded at the end of March, and a fourfold surge from the same period last year. Such explosive growth parallels the adoption rates of platforms like Zoom during the pandemic and early social media networks, highlighting the swift transition of AI tools from experimental to essential.

This week, ChatGPT is on track to reach 700M weekly active users — up from 500M at the end of March and 4× since last year. Every day, people and teams are learning, creating, and solving harder problems. Big week ahead. Grateful to the team for making ChatGPT more useful and…

This milestone occurs at a crucial juncture for OpenAI, as the company is reportedly gearing up to launch GPT-5 in early August, according to insiders. This timing indicates OpenAI's strategic maneuver to dominate the AI landscape before competitors can catch up.

“Every day, people and teams are learning, creating, and solving harder problems,” stated Nick Turley, OpenAI’s vice president of product for ChatGPT, when announcing this user benchmark. “Big week ahead.”

GPT-5 will combine reasoning powers into a single AI system

The forthcoming model promises more than just a minor upgrade. According to sources briefed on the project, GPT-5 will incorporate OpenAI’s advanced reasoning capabilities from its o3 series directly into the flagship GPT platform. CEO Sam Altman has described this as “a system that integrates a lot of our technology.”

This integration represents a strategic pivot for OpenAI, which has previously released reasoning models separately from its general-purpose language models. By merging these capabilities, the company aims to simplify user decisions on which model to use for specific tasks, while creating a more powerful unified system.

This consolidation aligns with OpenAI’s broader ambition to achieve artificial general intelligence, or AGI — a milestone that could significantly alter its partnership with Microsoft. Under their existing agreement, achieving AGI would require Microsoft to forfeit its rights to OpenAI’s revenue and future models, potentially reshaping one of the most impactful partnerships in technology.

However, Altman has moderated expectations, stating that GPT-5 won’t achieve “gold level of capability for many months” post-launch, indicating that the AGI threshold remains distant.

Business customers jump to 5 million as revenue hits $13 billion

The growth in users reflects ChatGPT’s expanding influence in corporate America. OpenAI now caters to 5 million paying business customers, an increase from 3 million in June, as enterprises increasingly embed AI tools into their core operations. Daily user messages have exceeded 3 billion, indicating not just growth in users but heightened engagement with the platform.

This surge in business adoption has propelled OpenAI’s annual recurring revenue to $13 billion, up from $10 billion in June, with forecasts suggesting it could surpass $20 billion by year-end. The revenue growth, combined with a recent $8.3 billion funding round that valued OpenAI at $300 billion, provides the financial backing for the substantial infrastructure investments necessary to maintain its technological edge.

These investments are significant. OpenAI has agreed to a $30 billion annual lease with Oracle for data center capacity and has made an $11.9 billion deal with cloud provider CoreWeave, while also planning international expansion through partnerships like Stargate Norway and a major data center project in Abu Dhabi.

Google, Meta and Anthropic chase OpenAI’s dominant lead

The rapid growth occurs as OpenAI faces increasing pressure from well-funded competitors eager to seize market share. Google’s AI search product, AI Overviews, boasts 2 billion monthly users across more than 200 countries, while its Gemini App reports 450 million monthly active users. Anthropic, backed by substantial investments from Amazon and others, is reportedly seeking to raise up to $5 billion at a $170 billion valuation, according to Bloomberg.

Meta has made significant progress with its Llama models, while Elon Musk’s xAI continues to draw attention and investment. This competitive landscape has intensified the AI arms race, with companies investing billions into computing infrastructure and talent acquisition.

The competition has sparked a talent war among tech giants. Microsoft has reportedly hired more than 20 employees from Google’s DeepMind team in recent months, including former Gemini engineering head Amar Subramanya, as companies poach each other’s AI talent pools.

ChatGPT adds wellness features as AI safety concerns grow

While OpenAI pursues raw capability improvements, the company has also focused on optimizing ChatGPT for user well-being and productivity. The company recently outlined efforts to help users “thrive in the ways you choose—not to hold your attention, but to help you use it well.”
