Every single day, more than 150 million developers around the world push code, review pull requests, open issues, and collaborate on projects through one platform. GitHub has become so central to how software gets built that for most developers, it is simply where work happens — as natural and essential as electricity. But behind those green contribution graphs and endless repositories is an ownership story that involves two co-founders who bootstrapped one of the most valuable startups in history without needing a single dollar of outside money for four full years, a $7.5 billion acquisition by the most powerful software company on Earth, and a dramatic leadership shake-up in 2025 that marked the end of GitHub’s independence as a standalone company.
Here is the complete, verified story of who owns GitHub — right up to today in 2026.
What Is GitHub?
GitHub began in 2008 as a web-based platform built around Git — the open-source version control system created by Linux founder Linus Torvalds. GitHub’s founders turned Git repositories into a social collaboration platform where software developers could review code, manage projects, and contribute to open-source projects.
Today, GitHub hosts over 500 million repositories and serves more than 150 million developers as of early 2026, making it the largest and most important code hosting platform in the world.
In June 2025, GitHub surpassed one billion repositories and forks — a milestone celebrated across the entire developer community. In a moment of perfect internet humor, the billionth repository was named simply “shit”, a fact cheerfully acknowledged by GitHub staff worldwide.
Who Owns GitHub Right Now in 2026?
GitHub is owned by Microsoft Corporation — a publicly traded technology company listed on NASDAQ under the ticker symbol MSFT. GitHub itself has no separately traded shares, no public shareholders, and no independent market capitalization. Microsoft acquired all issued and outstanding GitHub shares in 2018.
Today GitHub operates as a wholly owned Microsoft subsidiary within the Intelligent Cloud segment. The ultimate owners of GitHub are therefore Microsoft shareholders — with major institutional holders as of early 2026 including Vanguard (~8.9%), BlackRock (~7.2%), and State Street (~4.1%).
In plain terms: there is no such thing as GitHub stock. If you want to own a piece of GitHub, you buy Microsoft stock — and that is the only way to do it.

The Origin Story: Four Friends, No Outside Money, Pure Hustle
The founding of GitHub is one of the most unusual startup stories in Silicon Valley history — because it barely looks like a Silicon Valley story at all.
GitHub was founded in 2008 by Tom Preston-Werner, Chris Wanstrath, PJ Hyett, and Scott Chacon. It was bootstrapped and profitable for four years before taking outside money — an unusual path for a company of its eventual scale.
Most startups burn through investor cash from day one. GitHub did the opposite. The four founders built the platform, charged for private repositories, grew a massive community of open-source developers, and reached profitability without asking anyone for a single dollar. That self-sufficiency gave them an extraordinary amount of control and leverage when they finally did decide to raise money.
GitHub raised significant venture funding, including a $100 million round from Andreessen Horowitz in 2012, while Sequoia Capital and other investors participated in a $250 million funding round in 2015 at roughly a $2 billion valuation. These investors owned private-company stakes before the Microsoft acquisition.
Tom Preston-Werner resigned from GitHub in 2014 following an internal harassment investigation. Chris Wanstrath, who had stepped back from the CEO role, returned to it after Preston-Werner’s departure and led the company through to the Microsoft sale.
The $7.5 Billion Microsoft Deal
By 2018, GitHub had grown into the undisputed home of open-source software development. Every major technology company — Google, Apple, Amazon, Facebook — had thousands of engineers using it every day. It was critical infrastructure for the entire software industry.
Microsoft officially closed its acquisition of GitHub on October 26, 2018, after announcing the deal earlier that year, paying approximately $7.5 billion in Microsoft stock. The purchase was one of the largest in Microsoft CEO Satya Nadella’s era of acquisitions, and it signaled a major shift for a company once known for viewing open-source software as a competitive threat.
The developer community initially reacted with deep suspicion. Many feared that Microsoft — which had spent years fighting open-source software before eventually embracing it — would commercialize GitHub, restrict access, or merge it into its own products. Microsoft kept GitHub operating as an independent brand, introduced free private repositories, and focused on adding AI features like GitHub Copilot rather than merging GitHub into other Microsoft products.
That hands-off approach helped calm the community’s fears — and proved strategically brilliant. By preserving GitHub’s culture and brand, Microsoft kept developers loyal while quietly integrating the platform into its growing cloud and AI empire.
Nat Friedman, a Microsoft corporate vice president, became GitHub’s CEO, succeeding Chris Wanstrath immediately after the acquisition closed. Friedman led GitHub until 2021, when he stepped down and was succeeded by Thomas Dohmke.
The 2025 Leadership Shake-Up That Changed Everything
Just when developers had grown comfortable with GitHub’s semi-independent structure inside Microsoft, a bombshell announcement in August 2025 fundamentally changed the relationship between the two companies forever.
On August 11, 2025, Microsoft announced that GitHub CEO Thomas Dohmke would be stepping down as leader of the platform. GitHub had operated largely on its own since its acquisition by Microsoft in 2018. However, with the rise of GitHub Copilot and the broader growth of AI-powered software development, GitHub’s fortunes became increasingly tied to those of its parent company.
Dohmke’s departure coincided with GitHub’s full integration into Microsoft’s CoreAI division, signaling the end of the platform’s independent leadership structure. GitHub’s leadership reports more directly to the CoreAI group. Oversight of revenue, engineering, and support shifted to Julia Liuson, head of Microsoft’s Developer Division. Product leadership reports to Asha Sharma, VP of AI Platform at Microsoft.
Crucially, Microsoft does not plan to appoint a new CEO for GitHub. Instead, GitHub’s leadership will report into Microsoft’s recently formed CoreAI division, led by former Meta engineering chief Jay Parikh.
Dohmke wrote in his farewell blog post: “After all this time, my startup roots have begun tugging on me and I’ve decided to leave GitHub to become a founder again.” He pledged to stay through the end of 2025 to oversee the transition.
This decision to not replace the CEO is significant. It means GitHub no longer operates as an independent subsidiary with its own leader and strategy. It is now simply a product division within Microsoft’s AI engineering organization — fully absorbed into the parent company after seven years of managed autonomy.
GitHub Copilot: The Product That Changed Everything
The most important story coming out of GitHub in the last three years is not about repositories or version control — it is about Artificial Intelligence.
During Dohmke’s tenure, GitHub Copilot evolved from a simple auto-completion tool into a sophisticated coding partner offering conversational coding, voice interaction, code fixing, and even full-stack app generation — with over 20 million users.
Microsoft CEO Satya Nadella noted that GitHub Copilot had grown into a business larger than GitHub itself was at the time of the 2018 acquisition. GitHub Copilot boasts more than 20 million users and has transformed how a growing number of developers write code.
That statement is extraordinary. Microsoft paid $7.5 billion for GitHub in 2018. By 2025, the AI product built on top of GitHub’s data and platform had grown larger than the original $7.5 billion business. The integration into CoreAI is a direct acknowledgment that GitHub’s future value lies almost entirely in its role as a foundation for AI-powered software development — not as a standalone code hosting service.
How Big Is GitHub in 2026?
The scale of GitHub in 2026 is staggering by any measure.
During Dohmke’s tenure, the developer community expanded to over 150 million users, the platform surpassed 1 billion repositories and forks, and GitHub Actions now powers 3 billion minutes of CI/CD workloads per month.
GitHub’s revenue exceeded $1 billion ARR (Annual Recurring Revenue) by late 2022 and has grown further through enterprise and AI-driven subscription offerings through 2026.
And the competitive landscape has never been more intense. GitHub faces a torrent of competition from AI-powered coding tools — from Cursor, Windsurf, Replit, and others — all competing for developer attention in what has been called the “vibe coding” gold rush, a workflow where developers use natural language to generate code at high speed. The integration into Microsoft’s CoreAI is partly a response to this competitive pressure — bringing GitHub closer to Microsoft’s frontier AI research and resources to help it stay ahead.
