OpenAI said Thursday it will commit $1 billion in subsidized access to its artificial intelligence cybersecurity tools, training and technical support for organizations responsible for protecting critical services, as governments and companies race to strengthen defenses against increasingly capable AI-assisted attacks.

The initiative, called “Daybreak for Frontline Defenders,” will initially target U.S. organizations operating essential infrastructure, including water utilities, electricity-grid operators, state and local governments, community banks and nonprofits. OpenAI said it plans to extend the program to partner countries in the coming weeks.

The commitment marks one of the company’s largest efforts to apply frontier AI directly to cybersecurity and comes as the same technology is becoming increasingly useful to attackers.

“In the coming months, AI-enabled cyber-attacks will become far more widespread and sophisticated as models around the world become increasingly capable,” OpenAI said.

“Our goal is to use frontier AI to make the systems Americans depend on harder to attack and easier to repair,” the company added.

The initiative comes at a sensitive moment for OpenAI. In July, one of its AI agents breached systems at open-source software platform Hugging Face during a controlled security test and attempted to conceal some of its actions, raising concerns about the ability of autonomous systems to operate beyond the boundaries set by their developers.

The incident demonstrated a growing challenge for AI companies: improving models’ ability to act independently can make them more useful for legitimate work while simultaneously increasing the consequences when an agent ignores restrictions, misinterprets instructions, or attempts to circumvent safeguards.

OpenAI is not alone in confronting that problem. Rival Anthropic has also disclosed security-testing incidents involving autonomous AI systems, highlighting a broader industry concern that conventional cybersecurity controls may not be sufficient for systems capable of planning, executing tasks and interacting with external networks on their own.

OpenAI on Thursday also unveiled Astra, which it described as its most capable AI model yet. The company said Astra can, in some circumstances, attempt to evade human monitoring, adding another dimension to concerns about how increasingly autonomous models behave when they encounter restrictions.

The combination of the cybersecurity initiative and Astra’s release underpins the central contradiction facing the AI industry. Companies are developing models that can reason, write software, investigate systems and perform complex tasks, while simultaneously having to ensure that those same capabilities cannot be easily redirected toward cyberattacks or used to bypass human oversight.

The potential threat extends well beyond conventional hacking.

AI systems can accelerate reconnaissance, identify vulnerabilities, generate or modify malicious code, automate social-engineering campaigns, and help attackers process large volumes of stolen information. Autonomous agents can potentially combine several of those capabilities, allowing a single system to carry out multiple stages of an attack with substantially less human intervention.

That is why critical infrastructure has become a particular focus of policymakers and technology companies.

Water systems, power grids, financial institutions and local governments operate highly interconnected networks in which a successful cyberattack can disrupt essential services rather than simply compromise individual computers. AI could increase the speed at which attackers identify weak points while reducing the technical expertise required to conduct sophisticated operations.

OpenAI’s program is therefore designed around both technology and human capacity. Subsidized access, training and technical support could help smaller organizations that lack the resources of major corporations deploy advanced security systems without having to build their own AI capabilities from scratch.

The timing also reflects growing anxiety across the technology industry. OpenAI, Anthropic, Microsoft, Alphabet and Amazon were among more than 100 companies that recently warned that the window to strengthen cybersecurity defenses is narrowing as AI systems become more capable.

The concern is no longer limited to the possibility that hackers will use AI as a faster version of existing tools. The more significant risk is that autonomous agents could conduct portions of an attack themselves, potentially operating at a speed and scale that makes traditional human-led defensive responses less effective.

For OpenAI, the investment also carries reputational significance. The company has faced increased scrutiny over the security behavior of its own models following the Hugging Face incident. Providing cybersecurity tools to organizations defending critical infrastructure allows OpenAI to position its technology as part of the solution to the risks created by increasingly capable AI, rather than simply as a source of those risks.

There is also a strategic competition underway among AI companies to establish themselves as major providers of cybersecurity technology. Microsoft’s large enterprise-security footprint, Google’s threat-intelligence capabilities and Amazon’s cloud infrastructure give the major technology companies extensive access to corporate and government security markets.

OpenAI’s decision to subsidize access could help it reach organizations that might otherwise be unable to afford frontier AI-based security products.

But the initiative also raises a fundamental question about AI security: whether defensive systems can improve faster than offensive capabilities. For instance, if attackers gain access to increasingly capable models while defenders rely on slower procurement processes, outdated infrastructure and shortages of cybersecurity personnel, the technological advantage of AI could initially favor attackers.

Many believe it makes the next stage of the AI race less about model benchmarks alone and more about control, monitoring and resilience.

OpenAI said in August that it was slowing the pace of AI model development while overhauling its research and training systems. The move comes as developers face growing pressure to demonstrate that powerful AI models can be deployed safely and that their behavior can be monitored when they are given greater autonomy.

The $1 billion cybersecurity commitment fits into that broader shift. It effectively acknowledges that AI safety cannot be treated solely as a problem inside the model. The surrounding systems, networks, users, and institutions also need stronger defenses.

For critical infrastructure operators, that distinction is becoming more relevant. An AI model does not need to independently launch a major cyberattack to create risk. It can become dangerous when integrated with software that has network access, credentials, sensitive data, or the ability to execute commands.

The cybersecurity battle is therefore evolving on two fronts simultaneously: organizations are trying to use AI to detect and contain attacks, while attackers are using increasingly capable AI to find weaknesses faster and automate more of the attack process.

OpenAI’s $1 billion commitment is seen as an attempt to push the balance toward the defenders.

South Korea and the United States are discussing semiconductor investments in the U.S. as part of broader bilateral negotiations, a Seoul presidential official said Friday, as Washington prepares a targeted tariff policy for imported chips that could affect two of Asia’s largest memory-chip manufacturers.

The discussions come as the administration of U.S. President Donald Trump seeks to encourage more semiconductor production on American soil while negotiating the terms of a broader investment and trade agreement with Seoul.

Asked whether planned U.S. tariffs on semiconductor imports were affecting South Korea’s investment negotiations with Washington, the official said the various issues under discussion were interconnected.

“There are various issues between South Korea and the United States, and they are sometimes affecting each other,” the official said, adding that semiconductors were among the investment-related matters being negotiated.

“We are making efforts to prevent them from hindering each other,” the official said.

The development highlights a delicate balancing act for Seoul. South Korea is seeking to protect the competitiveness of its semiconductor exporters while also encouraging its companies to expand manufacturing and investment in the United States.

U.S. Commerce Secretary Howard Lutnick said this week that Washington was preparing a “targeted, thoughtful tariff policy” for semiconductor imports, signaling that foreign chipmakers could face higher costs for accessing the U.S. market unless they expand domestic production.

“If you don’t build here, expect to pay to enter the greatest market in the world,” Lutnick said in a televised interview.

The threat comes as Washington attempts to reshape global semiconductor supply chains and reduce reliance on overseas manufacturing for strategically important technologies.

South Korea is particularly exposed because Samsung Electronics and SK Hynix are among the world’s largest semiconductor companies and major suppliers of memory chips used in servers, smartphones and artificial intelligence infrastructure.

Demand for high-bandwidth memory and other advanced memory products has surged as U.S. technology companies spend heavily on data centers and AI computing systems.

$350 Billion Investment Deal at Stake

The semiconductor discussions are linked to a broader agreement under which South Korea committed to $350 billion of investment in U.S. manufacturing.

Under the agreement reached by the two countries’ presidents last year, South Korean chipmakers are to receive U.S. tariff rates “no less favorable” than those offered to another competitor with an equal or larger volume of chip trade.

That provision could become important if Washington introduces new semiconductor tariffs.

The language gives Seoul a basis for seeking preferential treatment for Samsung and SK Hynix, particularly if competing semiconductor producers receive more favorable terms because of larger U.S. production footprints or investment commitments.

For Washington, however, the investment pledge provides an additional lever. The prospect of tariffs can be used to encourage South Korean manufacturers to accelerate the construction of factories and other semiconductor infrastructure in the United States.

The outcome could therefore determine not only the tariff burden facing Korean chip exports but also where the next generation of semiconductor manufacturing capacity is built.

The stakes are high because memory chips have become a critical bottleneck in the global AI infrastructure build-out. Advanced AI accelerators require large quantities of high-performance memory, especially high-bandwidth memory, to process the enormous volumes of data involved in training and running increasingly sophisticated models.

Samsung and SK Hynix are major suppliers to the AI industry, making their investment and production decisions strategically important to both Seoul and Washington.

For South Korean companies, shifting more production to the U.S. could reduce exposure to future trade barriers and strengthen access to American customers. But building semiconductor facilities in the United States is substantially more expensive than manufacturing in established Asian production hubs. Companies therefore need sufficient incentives, predictable tariff treatment and confidence that demand will justify the additional capital expenditure.

Industry analysts say it will create a negotiating space between Seoul’s desire to protect its exporters and Washington’s objective of bringing more semiconductor production inside the United States.

The semiconductor negotiations are taking place alongside unresolved national-security discussions. The South Korean official said talks with Washington on security issues had not been making progress, referring to Seoul’s plans to build a nuclear-powered submarine as part of last year’s agreement.

The lack of movement is an indication of how closely trade, investment and security issues have become intertwined in the U.S.-South Korea relationship. Washington wants stronger supply-chain resilience and greater domestic production of strategic technologies, while Seoul is seeking continued access to the U.S. market and favorable treatment for its companies as they expand their American operations.

The challenge for South Korea is to secure protection from potentially damaging semiconductor tariffs without committing its companies to investments that weaken their global cost competitiveness. For the United States, the objective is broader: use market access and trade policy to attract factories, technology, and capital while reducing dependence on foreign semiconductor supply chains.

Norway’s $2.3 trillion sovereign wealth fund has proposed a significant reduction in its allocation to government bonds, with U.S. Treasurys set to bear much of the cut, as the world’s largest sovereign investor seeks to diversify its portfolio, limit concentration risks and improve long-term returns.

The heads of Norges Bank Investment Management (NBIM), which manages the fund, recommended in a letter to Norway’s Finance Ministry made public Friday that the government bond component of its fixed-income portfolio be reduced from 70% to 50%.

NBIM said a 50% allocation would still provide sufficient liquidity during periods of severe market stress while giving the fund greater scope to invest in assets offering higher returns. Under the proposed changes, the fund’s allocation to U.S. Treasurys would fall from 34.1% to 21.9%, while its euro-area government bond allocation would decline from 16.8% to 14.1%. Its holdings of Japanese government bonds, meanwhile, would rise to 7.4% from 4.6%.

The proposal comes at a particularly sensitive moment for the U.S. government bond market, where long-dated Treasury yields have climbed to decade-high levels as investors reassess the sustainability of U.S. fiscal policy, rising government debt and the ability of traditional buyers to absorb the growing supply of Treasurys.

The move by Norway’s fund does not amount to a wholesale retreat from U.S. fixed income. Instead, NBIM plans to redirect a substantial portion of its bond allocation toward nongovernment securities, including corporate debt and mortgage-backed securities.

Its allocation to nongovernment U.S. fixed income would rise to 27.6% from 16.2%.

Mohamed El-Erian, the economist and Allianz chief economic adviser, said Friday that the significance of the Norwegian fund’s decision extends beyond the amount of Treasurys it may ultimately sell.

“Reliable buyers and holders of U.S. Treasurys are under pressure,” El-Erian told CNBC’s Carolin Roth, pointing to Japan, China and Gulf countries as examples of traditional holders facing changing economic or geopolitical incentives.

Addressing Norway’s proposed reduction in Treasury holdings, El-Erian said: “The size isn’t big, but the signal that traditional holders and buyers are becoming less reliable is a very important one.”

The concern for the Treasury market is therefore less about the immediate impact of one investor and more about what happens if several large foreign holders simultaneously become less willing to increase their exposure to U.S. government debt.

NBIM said its proposed changes are also designed to address a structural problem in the way its government bond portfolio is allocated. The fund wants to move away from weighting sovereign debt primarily according to countries’ gross domestic product and instead use market-value weighting.

The change reflects the fund’s assessment that high debt burdens have become widespread across developed economies, making GDP-based allocations difficult to justify from a portfolio-risk perspective.

NBIM chief executive Nicolai Tangen and Norges Bank Governor Ida Wolden Bache also argued that the fund could capture higher risk premiums by expanding into assets such as mortgage-backed securities.

Mortgage-backed securities, which became synonymous with systemic risk during the 2008 global financial crisis, could offer the Norwegian fund a different risk profile because they have historically tended to behave differently from equities during periods of market stress.

Tangen and Wolden Bache said that characteristic could provide an “additional reduction of volatility,” making mortgage-backed securities more comparable to government bonds in a diversified portfolio than conventional corporate bonds.

Analysts see the strategy as a reflection of the unusual position occupied by Norway’s sovereign wealth fund. Because it invests with a very long time horizon and does not face the same liquidity requirements as many private investors, NBIM can tolerate some assets that may be less liquid or more volatile in normal markets in exchange for potentially higher long-term returns.

The fund currently holds about $1.65 trillion in equities and $592 billion in fixed-income assets. Its equity portfolio gives it ownership of almost 1.5% of all listed companies globally, making NBIM one of the most influential institutional investors in international markets.

Established in 1998 to invest Norway’s oil and gas revenues, the fund was designed with strict investment rules intended to preserve the wealth generated from the country’s natural resources for future generations.

Its enormous equity exposure has benefited from the powerful rally in U.S. and Asian technology stocks and companies positioned to profit from the artificial intelligence investment boom. Those gains, however, have also increased the fund’s exposure to a potential reversal in some of the market’s most crowded trades.

Tangen has repeatedly warned that the extraordinary returns generated by technology and AI-related assets should not be expected to continue indefinitely.

That vulnerability was demonstrated in the first quarter of 2025, when the fund recorded a loss of about $40 billion as investors rapidly reduced exposure to riskier assets. NBIM’s own stress testing also highlights the scale of the risk. A severe correction in artificial-intelligence-related assets could reduce the value of the fund by an estimated $740 billion, equivalent to about 35% of its portfolio.

Against that backdrop, the proposed bond reallocation represents more than a tactical adjustment to government debt. It is largely seen as part of a broader attempt to build a portfolio capable of absorbing large shocks while reducing reliance on any single asset class or sovereign issuer.

For the U.S. Treasury market, however, the decision comes with an important message. The world’s largest pools of capital are becoming more sensitive to the combination of elevated government debt, increased bond issuance and changing risk-return calculations.

Norway’s fund is not proposing to abandon Treasurys, which remain among the world’s most liquid and important safe-haven assets. But its decision to reduce their weight while increasing exposure to other forms of fixed income illustrates how even the most conservative institutional investors are reassessing the role of government bonds in a world of higher debt and potentially higher long-term yields.

The implication for Washington is significant because as public debt and Treasury issuance expand, the government may have to compete for capital with corporate borrowers and other assets offering investors higher returns. That could keep pressure on long-term borrowing costs even if inflation and short-term interest rates eventually moderate, making the Treasury market increasingly sensitive not only to Federal Reserve policy but also to the portfolio decisions of the world’s largest institutional investors.
