OpenAI’s Agentic Security Researcher Aardvark, Stargate Expansion And PayPal Deal

OpenAI is leaving no stone unturned in its quest to lead the artificial intelligence (AI) realm as it launches a barrage of new products, capabilities, and partnerships.

Recently, the company completed its transition to a public benefit corporation (PBC), where Microsoft saw its share in OpenAI revised to 27%, driving its valuation up to $500 billion. It even raised the remaining $22.5 billion due from SoftBank.

Now, the company is laying the groundwork for an initial public offering (IPO) that would see its worth jump to $1 trillion, according to sources familiar with the matter. This would be one of the biggest IPOs of all time.

The company is planning to file with security regulators in the second half of 2026.

It’s not just monetary gains that the company has been after.

In just the past few weeks, OpenAI launched its AI-powered browser, ChatGPT Atlas; released Company Knowledge; hinted at a AI music tool; unveiled UK data residency and other deals with the UK government; signed a deal with Broadcom for AI chips; partnered with AMD to deploy 6 gigawatts of AMD GPU computing power; brought the next iteration of its AI video generator, Sora 2; and even held its annual developer conference OpenAI Dev Day 2025, which itself saw a wide range of announcements.

Now, the company has revealed a series of moves that further enhance its offerings, infrastructure, and integrations.
 

Aardvark: The Agentic Security Researcher

OpenAI announced Aardvark, an agentic security researcher that’s powered by its latest GPT-5 model.

This autonomous agent can help developers and security teams discover and fix security vulnerabilities at scale, representing “a breakthrough in AI and security research.”

Essentially, it continuously analyzes source code repositories to identify vulnerabilities, find exploitative areas, prioritize severity, and propose targeted patches by using LLM-powered reasoning and tool-use to understand code behavior.

First, it analyzes the full repository, then scans for vulnerabilities by inspecting commit-level changes against the entire repository, then triggers potential identified vulnerabilities in an isolated, sandboxed environment, and then integrates with OpenAI Codex to offer fixes.

“Aardvark works alongside engineers, integrating with GitHub, Codex, and existing workflows to deliver clear, actionable insights without slowing development,” reads the announcement. “While Aardvark is built for security, in our testing we’ve found that it can also uncover bugs such as logic flaws, incomplete fixes, and privacy issues.”

OpenAI said the tool has been used across its internal codebases and by external alpha partners for several months. It has also been applied to open-source projects and works alongside engineers, integrating with GitHub, Codex, and existing workflows.

Upon testing, Aardvark identified 92% of known and synthetically introduced vulnerabilities.

As such, the company feels the tool will be effective in preventing Common Vulnerabilities and Exposures (CVE), which have been on the rise recently.

Aardvark is currently in private beta through invitation to select partners. Here, participants will gain early access and work with OpenAI to refine detection accuracy and more.

 

Stargate Expands To Michigan

OpenAI announced a new Stargate campus in Saline Township, Michigan, which comes as part of its 4.5 gigawatt partnership⁠ with Oracle.

The Stargate Michigan campus is being developed by Related Digital⁠—an integrated data center development and investment platform—and Oracle. Its construction is expected to begin in early 2026 and will create over 2,500 union construction jobs.

The new campus will offer over one gigawatt, and when combined with the other announced campuses—in Texas, New Mexico, Wisconsin, and Ohio—built in collaboration with Oracle and SoftBank, it brings Stargate’s total planned capacity to more than 8 gigawatts, coming at a cost of over $450 billion in investment over the next three years.

“We're investing through Stargate to help ensure communities across the country benefit both from building AI infrastructure and from all of the progress that AI itself makes possible,” says OpenAI.
 

ChatGPT PayPal Integration

PayPal intends to bring millions of OpenAI’s ChatGPT users the ability to check out instantly using PayPal, as well as support payments processing for merchants using OpenAI Instant Checkout, by adopting the Agentic Commerce Protocol (ACP) to expand payments and commerce in ChatGPT.

Furthermore, the payments platform will connect its global merchant network to OpenAI, allowing tens of millions of its users to sell within ChatGPT.

The move will bring convenient features from PayPal's wallet in Instant Checkout, spanning funding options such as bank, balance, cards, PayPal's buyer and seller protections, and post-purchase services such as tracking and dispute resolution.

PayPal will also support OpenAI Instant Checkout through the delegated payments API, managing payment processing for card payments.

Furthermore, the partnership will see PayPal bring access to ChatGPT Enterprise for its 24,000+ employees.

"By partnering with OpenAI and adopting the Agentic Commerce Protocol, PayPal will power payments and commerce experiences that help people go from chat to checkout in just a few taps for our joint customer bases," said Alex Chriss, President and CEO of PayPal.

Do you think these moves will help OpenAI strengthen its leading position in the AI sector?
