OpenAI on Monday said it raised US$40 billion in a new funding round that valued the ChatGPT maker at US$300 billion, the biggest capital-raising session ever for a start-up.
ChatGPT is an artificial intelligence (AI) chatbot launched in November 2022.
The infusion of cash comes in a partnership with Japanese investment giant Softbank Group Corp and “enables us to push the frontiers of AI research even further,” the San Francisco-based company said in a post on its Web site.

“Their support will help us continue building AI systems that drive scientific discovery, enable personalized education, enhance human creativity and pave the way toward AGI [artificial general intelligence] that benefits all of humanity,” the company said.
AGI refers to a computing platform with human-level intelligence.
Softbank said in a news release that it is on a mission to realize artificial super intelligence (ASI) that surpasses human intelligence, and that OpenAI is the partner closest to achieving that goal.
“The advancement of OpenAI’s AI models is key to achieving AGI and ASI, and massive computing power is essential,” Softbank said in its rationale for the latest investment in the company.
Softbank is to pump US$10 billion into OpenAI to start, and US$30 billion more by the end of this year pending certain conditions.
OpenAI plans to scale its infrastructure and “deliver increasingly powerful tools for the 500 million people who use ChatGPT every week.”
The funding news came the same day OpenAI announced it was building a more open generative AI model as it faces growing competition in the open-source space from Chinese rival DeepSeek (深度求索) and Facebook parent Meta Platforms Inc.
The move would mark a strategic shift by OpenAI, which until now has been a fierce defender of closed, proprietary models that do not allow developers to modify the basic technology to make AI more adapted to their goals.
OpenAI and defenders of closed models — which include Alphabet Inc’s Google — have often decried open models as riskier and more vulnerable to nefarious uses by malicious actors or non-US governments.
OpenAI’s embrace of closed models has also been a bone of contention in its battles with former investor Elon Musk, who has called on OpenAI to honor the spirit of the company’s name and “return to the open-source, safety-focused force for good it once was.”
Putting pressure on OpenAI, many large companies and governments have proved reluctant to build their AI products or services on models they have no control over, especially when data security is a concern.
The core selling point of Meta’s family of Llama models or DeepSeek’s models is addressing such worries by letting companies download their models, and have far greater control to modify the technology for their own purposes and keep control of their data.
“We’ve been thinking about this for a long time, but other priorities took precedence. Now it feels important to do,” OpenAI chief executive Sam Altman wrote on X of the decision to build a more open model.
Meanwhile, the frenzy to create Ghibli-style AI art using ChatGPT's image-generation tool led to a record surge in users for the chatbot last week, straining its servers and temporarily limiting the feature's usage.
The viral trend saw users from across the globe flood social media with images based on the hand-drawn style of the famed Japanese animation outfit, Studio Ghibli, founded by renowned director Hayao Miyazaki and known for movies such as "Spirited Away" and "My Neighbor Totoro."
Average weekly active users breached the 150 million mark for the first time this year, according to data from market research firm Similarweb.
"We added one million users in the last hour," Altman said in an X post on Monday, comparing it with the addition of one million users in five days following ChatGPT's red-hot launch more than two years ago.
That claim came days after Altman said the new image features were so popular that they were melting the OpenAI graphics processing units that power the AI due to heavy use.

SEEKING CLARITY: Washington should not adopt measures that create uncertainties for ‘existing semiconductor investments,’ TSMC said referring to its US$165 billion in the US Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) told the US that any future tariffs on Taiwanese semiconductors could reduce demand for chips and derail its pledge to increase its investment in Arizona. “New import restrictions could jeopardize current US leadership in the competitive technology industry and create uncertainties for many committed semiconductor capital projects in the US, including TSMC Arizona’s significant investment plan in Phoenix,” the chipmaker wrote in a letter to the US Department of Commerce. TSMC issued the warning in response to a solicitation for comments by the department on a possible tariff on semiconductor imports by US President Donald Trump’s
The government has launched a three-pronged strategy to attract local and international talent, aiming to position Taiwan as a new global hub following Nvidia Corp’s announcement that it has chosen Taipei as the site of its Taiwan headquarters. Nvidia cofounder and CEO Jensen Huang (黃仁勳) on Monday last week announced during his keynote speech at the Computex trade show in Taipei that the Nvidia Constellation, the company’s planned Taiwan headquarters, would be located in the Beitou-Shilin Technology Park (北投士林科技園區) in Taipei. Huang’s decision to establish a base in Taiwan is “primarily due to Taiwan’s talent pool and its strength in the semiconductor
An earnings report from semiconductor giant and artificial intelligence (AI) bellwether Nvidia Corp takes center stage for Wall Street this week, as stocks hit a speed bump of worries over US federal deficits driving up Treasury yields. US equities pulled back last week after a torrid rally, as investors turned their attention to tax and spending legislation poised to swell the US government’s US$36 trillion in debt. Long-dated US Treasury yields rose amid the fiscal worries, with the 30-year yield topping 5 percent and hitting its highest level since late 2023. Stocks were dealt another blow on Friday when US President Donald
UNCERTAINTY: Investors remain worried that trade negotiations with Washington could go poorly, given Trump’s inconsistency on tariffs in his second term, experts said The consumer confidence index this month fell for a ninth consecutive month to its lowest level in 13 months, as global trade uncertainties and tariff risks cloud Taiwan’s economic outlook, a survey released yesterday by National Central University found. The biggest decline came from the timing for stock investments, which plunged 11.82 points to 26.82, underscoring bleak investor confidence, it said. “Although the TAIEX reclaimed the 21,000-point mark after the US and China agreed to bury the hatchet for 90 days, investors remain worried that the situation would turn sour later,” said Dachrahn Wu (吳大任), director of the university’s Research Center for
