ChatGPT Reaches 900M Weekly Active Users: OpenAI Secures $110B in Historic Funding
The era of mass-market AI has officially arrived. On Friday, February 27, 2026, OpenAI announced that its flagship chatbot, ChatGPT, has surpassed 900 million weekly active users (WAU). This puts the platform within striking distance of the elusive 1-billion-user milestone, a feat previously reserved for social media giants like Meta and Google.
In addition to the staggering user growth, OpenAI shared that it now boasts 50 million paying subscribers. This growth is being fueled by an unprecedented start to 2026, with January and February projected to be the largest months for new subscriptions in the company’s history.
The Road to 1 Billion: Growth and Reliability
The leap to 900 million users represents a gain of 100 million active users in just four months, up from the 800 million reported in October 2025. OpenAI attributes this acceleration to significant improvements in the “felt” user experience:
-
Higher Reliability: Near-zero downtime even during peak global hours.
-
Consistent Performance: The rollout of more efficient models has led to faster response times across both free and Plus tiers.
-
Utility Across Sectors: From individual learners to enterprise developers building on ChatGPT, the platform has become a “must-have” productivity tool.
A Historic $110 Billion Funding Round
The user growth announcement was paired with the news of a colossal $110 billion private funding round, valuing OpenAI at a staggering $730 billion pre-money valuation. This is one of the largest private capital raises in corporate history and underscores the massive infrastructure costs required to sustain the AGI (Artificial General Intelligence) race.
Key Investors and Contributions:
-
Amazon: $50 Billion (Solidifying a major partnership alongside AWS).
-
Nvidia: $30 Billion (Ensuring OpenAI has priority access to next-gen Blackwell and Rubin GPUs).
-
SoftBank: $30 Billion (Driven by Masayoshi Son’s vision for an AI-first economy).
OpenAI indicated that the funding round remains open, with more institutional investors expected to join in the coming weeks.
Investment in the Future of AGI
With $110 billion in fresh capital, OpenAI is expected to accelerate several key initiatives:
-
Stargate Supercluster: Expanding the massive data center projects intended to house millions of AI chips.
-
Custom Silicon: Reducing dependence on external providers by ramping up internal chip design teams.
-
Advanced Reasoning: Continued development of the “Strawberry” (o1) and “Orion” (GPT-5) series to move closer to human-level reasoning.
