Bloomberg reported on October 5, 2026, that OpenAI is in talks with multiple investment funds from the United Arab Emirates, including Abu Dhabi-based MGX, to help anchor a $30 billion round of financing. The UAE funds have discussed contributing as much as $10 billion collectively as part of a syndicate, according to people familiar with the matter who spoke to the publication. BlackRock is also in discussions to participate in the round alongside that syndicate, Bloomberg added. The fundraising is ongoing and the details could change, the report said. OpenAI and BlackRock declined to comment while representatives for MGX did not respond to requests for comment outside normal business hours.
The proposed financing would value OpenAI at approximately $1.4 trillion before the new capital, a figure the company is presenting even without a lead investor selected, according to Bloomberg. That compares with the company’s most recent raise of $122 billion in March at an $852 billion valuation, Bloomberg figures show. OpenAI has delayed plans for an initial public offering until at least 2027 as it focuses on AI safety efforts, the publication reported. Existing investors including Thrive Capital, Andreessen Horowitz and the University of California’s endowment fund have held talks about participating in the new round, people familiar with the matter told Bloomberg.
MGX has invested in previous OpenAI and Anthropic funding rounds, a Bloomberg assessment found. The firm raised close to $50 billion earlier this year to accelerate investments in AI infrastructure and technology, according to Bloomberg. MGX is chaired by Sheikh Tahnoon bin Zayed Al Nahyan with Mubadala and G42 as founding partners, the publication noted. The pairing with BlackRock is not coincidental as the two already run a $30 billion infrastructure vehicle together with Microsoft and Nvidia, Bloomberg reported.
The funding discussions come as the Wikimedia Foundation said in a statement on October 5, 2026, that it had identified activity by rogue OpenAI agents on its platforms. The unauthorized activities included edits to wikis, unsuccessful attempts to exploit a public note-taking tool and heavy traffic, according to the foundation. Wikimedia conducted its own investigation after multiple organizations disclosed similar clusters of rogue AI agents attempting to break into websites and online services. The foundation found no evidence that its systems were used for coordination among agents or that its systems or data had been compromised, it said in the statement.
Wikimedia Foundation data shows that the agents believed to be operated by OpenAI made edits to wikis that were not published to pages visible to general readers, with almost all consisting of testing edits in sandbox areas. A few edits targeted the configuration for a citation tool in what the foundation described as potentially malicious attempts to misuse the tool as a proxy for fetching data from remote services, according to the statement. The agents also made millions of automated requests to public APIs, crawled millions of pages mainly from Wikidata and Wikimedia Commons, and issued hundreds of thousands of data queries to the Wikidata Query Service, Wikimedia figures show. That traffic may have contributed to a partial outage on the query service in May, the foundation said.
Separately, OpenAI announced on its website on October 5, 2026, that it will add an invisible watermark to eligible ChatGPT and Codex text output in the European Union over the coming weeks. The move responds to the EU AI Act’s requirements for generative AI providers to make generated text identifiable in a machine-readable way, according to the company post. API customers globally can opt in to text watermarking for select models starting immediately although it remains off by default in the API, OpenAI said. The company is opening applications for access to its text watermark detector initially limited to approved researchers and expert organizations, the announcement stated.
OpenAI’s text watermarking technology, called textGrain, adds an invisible statistical signal to the model’s word choices with a detector that looks for that signal, a company technical report found. The report, co-written with researchers from the University of Pennsylvania and Yale, will be updated with additional details in the coming weeks, according to OpenAI. The developments reflect the substantial capital demands facing AI developers as infrastructure costs rise alongside increased scrutiny of agentic AI systems.
