OpenAI is today one of the most influential and most closely monitored companies in the history of technology. Founded in December 2015 as a nonprofit research lab dedicated to general artificial intelligence (AGI) “for the benefit of all humanity,” it has since transformed into a Public Benefit Corporation (PBC) controlled by the OpenAI Foundation, valued at $852 billion after a record fundraising round of $122 billion closed on March 31, 2026. It generates about $2 billion in monthly revenue (annualized run-rate around $25–40 billion depending on sources and periods in 2026), has more than 900 million weekly active users on ChatGPT (and surpassed one billion monthly users on the app), and has a portfolio of frontier models up to GPT-6 Astra, Sol, and Luna.
OpenAI
The company redefined mainstream AI adoption with the launch of ChatGPT in November 2022, built a structural partnership with Microsoft (about 27% stake valued around $135 billion), diversified its compute sources (Microsoft Azure, AWS, Oracle, Nvidia, SoftBank via Stargate), and prepared a possible IPO (confidential S-1 filing in June 2026 potentially targeting more than $1 trillion). It remains unprofitable in the short term, with high losses tied to compute and R&D costs, and faces intense competition from Anthropic, Google DeepMind, xAI, Meta, and Chinese players such as DeepSeek.
This report details the history, governance, products, finances, partnerships, competition, risks, and outlook for OpenAI as of September 30, 2026. It is based on official announcements, market data, and available analyses.
1. History and founding (2015-2019)
OpenAI was founded on December 11, 2015 (incorporated on December 8) in San Francisco as a 501(c)(3) nonprofit organization. Co-founders included Sam Altman (then president of Y Combinator), Elon Musk, Greg Brockman, Ilya Sutskever, Wojciech Zaremba, John Schulman, and others. The initial seed capital was about $1 billion in commitments, coming in particular from Musk, Peter Thiel, Reid Hoffman, Jessica Livingston, Amazon Web Services, Infosys, and YC Research. The stated mission was clear: “ensure that general artificial intelligence benefits all of humanity,” without financial return constraints.
Gradually
At the time, the main motivation was fear of power concentration of AI in the hands of Google (via DeepMind acquired in 2014) and other giants. Musk and Altman advocated an open, collaborative approach. The early years were marked by foundational research: GPT-1 (2018), advances in reinforcement learning, and open publications.
Tensions emerged quickly. Musk, who had contributed significantly (about $38-45 million depending on sources, far from the $1 billion sometimes cited), argued for stronger control, even a merger with Tesla or a CEO role. In 2017-2018, disagreements over the for-profit structure and the pace of progress led Musk to leave the board in February 2018 (officially to avoid conflicts of interest with Tesla). He continued to criticize the shift to a “closed-source” approach and commercialization.
The Verge
In March 2019, faced with massive capital needs for compute (the data centers required already cost hundreds of millions), OpenAI created a “capped-profit” structure: OpenAI LP, controlled by the nonprofit via a general partner. Investor returns were capped (initially at 100x), with the excess theoretically reverting to the nonprofit. This enabled the first major Microsoft investment ($1 billion). This shift was criticized by Musk as abandoning the original mission.

2. Acceleration and commercial pivot (2019-2023)
Microsoft multiplied investments (up to more than $13 billion total before later restructurings), providing Azure credits and distribution via Bing, Office, and GitHub Copilot. The models progressed quickly: GPT-2 (2019, partial restraint for security reasons), GPT-3 (2020, commercial API), DALL-E (2021), then GPT-4 (March 2023).
The decisive turning point was the launch of ChatGPT on November 30, 2022. In five days, the product reached 1 million users; in two months, 100 million. This triggered the global “AI race,” forcing Google, Meta, and others to accelerate. ChatGPT democratized LLMs and generated recurring revenue through Plus subscriptions ($20/month).
In November 2023, a major governance crisis erupted: the board (including Ilya Sutskever) fired Sam Altman for “lack of candor.” Greg Brockman resigned in solidarity. More than 700 employees threatened to leave, Microsoft played a mediating role, and Altman was reinstated within days. The board was largely renewed (Bret Taylor as chairman). This episode highlighted tensions between the security mission and commercial imperatives.

3. Restructuring into a Public Benefit Corporation and scaling (2024-2026)
In October 2025, OpenAI completed its transformation into OpenAI Group PBC, controlled by the OpenAI Foundation (the original nonprofit). Microsoft holds about 27% (valued at ~135 billion at the time). The investors’ return cap was removed. This structure aims to reconcile commercial scale with a public mission.

Fundraising has accelerated:
March 2025: ~40 billion to ~300 billion valuation (SoftBank lead).
February-March 2026: $122 billion in committed capital to $852 billion post-money (SoftBank, Amazon $50 billion including some conditional portion, Nvidia $30 billion, a16z, D.E. Shaw, MGX, TPG, T. Rowe Price, Microsoft, etc.). First significant opening to individual investors via banks (~$3 billion) and inclusion in ARK ETFs.
OpenAI
In June 2026, confidential S-1 filing for an IPO potentially targeting more than $1 trillion. Timing remains flexible (possible 2026-2027). Secondary sales by employees (several billions) occurred at the same valuation.
4. Products and technology ecosystem (as of September 2026)
ChatGPT remains the flagship product. More than 900 million weekly active users (early 2026), with the app exceeding 1 billion monthly users (June/July 2026 per Sensor Tower). Third parties: Free/Go (with ads since early 2026), Plus ($20), Pro (up to $200-500 for Ultrafast and maximum capabilities), Business and Enterprise. Enterprise represents >40% of revenue and is moving toward parity. Ads billed have reached $100M ARR quickly.

Sora: video generation (launched as a standalone app in 2025, discontinued in 2026 to reallocate compute toward coding and enterprise—too-high costs).
Operator, agents, Dots (always-on agents with their own cloud computer, announced DevDay 2026).
API: billions of tokens per minute, the foundation for thousands of applications.
Daybreak : cybersecurity.
Acquisition of io (Jony Ive) for consumer hardware (~$6.5 billion).
Agent tools, Realtime API, etc.
OpenAI opened Codex harness as open source and multiplied cloud partnerships (Microsoft, AWS $38 billion over 7 years, Oracle, CoreWeave, custom silicon with Broadcom).
5. Financial performance
Revenues:
2023: ~1-2 billion.
2024: several billions.
Late 2025 / early 2026: ~20-25 billion annualized.
Mid-2026: up to ~40 billion annualized according to some estimates (Sacra), with $2 billion/month officially confirmed. Enterprise is growing rapidly.
Sacra
Costs: extremely high (compute, talent, Stargate infrastructure). Significant net losses (e.g., ~21 billion in 2025 according to some leaks). Expected cash-flow profitability not before 2030 in internal projections. Valuation: $852 billion (March 2026), with discussions of an IPO >$1 trillion. Total raised: far beyond $150-190 billion cumulative depending on sources.
Revenue structure: consumer subscriptions (~50-60%), API + enterprise, emerging ads, and potential future hardware/agent revenues.
6. Strategic partnerships
Microsoft: longstanding partner, distribution (Copilot, Azure), ~27% stake. Relationship revised in 2026 (less exclusivity, capped revenue share).
Amazon/AWS: massive investment + compute contract.
Nvidia: chips, investment.
SoftBank: lead investor, Stargate.
Oracle, CoreWeave, etc.
Diversification to reduce dependence on a single cloud.
7. Competition
The market has fragmented. ChatGPT remains the leader in raw users and time spent, but its web/app market share has fallen to around 46-54% (according to Sensor Tower/Similarweb sources mid-2026), down against Gemini (Google, OS and Search distribution, ~27-28%) and Claude (Anthropic, ~9-10%, strong in enterprise and coding, with run-rate revenues sometimes cited as higher). DeepSeek, Grok (xAI), Meta AI, Perplexity, and Chinese players are gaining ground.
Officechai
Anthropic has sometimes surpassed OpenAI in valuation and enterprise revenues according to some periods in 2026. Competition centers on agent capabilities, coding, multimodality, cost/token, security, and distribution.
8. Controversies, risks, and governance
Perceived abandonment of the nonprofit mission (Musk lawsuit, rejected in 2026 for statute of limitations).
2023 board crisis.
AGI security, alignment, existential risks versus a commercial race.
Compute costs unsustainable in the long term without profitability.
Regulation (EU AI Act, US, China), geopolitical dependence on US chips.
Concentration of power, impact on jobs, disinformation, intellectual property (training data).
Sora discontinued: an illustration of the economic limits of large-scale video generation.
The PBC + Foundation structure aims to protect the mission, but critics remain concerned about investor and Microsoft influence.
9. Impact and outlook
OpenAI has accelerated AI adoption in a historic way. ChatGPT became a daily tool for writing, coding, research, education, and productivity. The company is pushing toward autonomous agents (Dots, computer use), hardware, and deep integration into workflows.
Outlook 2026-2030:
Continue scaling the models (GPT-7 and beyond, 80-90% of R&D already oriented there).
Achieve parity or dominate enterprise.
Potential IPO.
Progressive profitability via volume, efficiency, ads, and monetized agents.
Risks: open-weight competition, regulation, costs, technical execution.
For the crypto/Web3 ecosystem (relevant for Binance): OpenAI powers agents, on-chain analytics tools, conversational interfaces, and could influence decentralized AI protocols. Frontier models remain centralized, but the API and partial open-source create opportunities.
10. Conclusion
OpenAI embodies the rapid transition from foundational research to the global economic infrastructure of AI. Its valuation, user base, and technological lead make it the de facto leader, even as competition intensifies and profitability remains a distant horizon. The central question for the coming years will be whether the governance structure and original mission can coexist with the imperatives of a company nearing a $1 trillion valuation, and whether AGI (or its agent precursors) will actually deliver the broad benefit that was promised.
This report will remain to be updated as announcements come in (DevDay, IPO, new models). Private financial data includes approximations; official OpenAI figures and primary market analyses should be prioritized.
