Anthropic is engaged in urgent talks with Trump administration officials in Washington on Monday in an attempt to resolve a new dispute over its most advanced AI models, following a surprise export control directive that has temporarily halted access to Fable 5 and Mythos 5 for all users.

The directive, issued Friday under national security authorities, ordered the company to suspend access to the models “by any foreign national, whether inside or outside the United States.” In response, Anthropic disabled the models entirely to ensure full compliance, a move that affects hundreds of thousands of enterprise customers and paid subscribers who had just begun using the newly released systems.

The action marks the latest flashpoint in Anthropic’s increasingly complicated relationship with the U.S. government. Earlier this year, the Pentagon labeled the company a supply chain risk after it refused to allow its Claude models to be used for domestic surveillance or fully autonomous weapons. That designation banned defense contractors from using Anthropic technology and prompted the startup to file a lawsuit that remains ongoing.

Defense Secretary Pete Hegseth defended the latest restrictions on X, writing that “every passing day” proves why blacklisting Anthropic was “the right move.”

Fable 5 and Mythos 5 were unveiled just days before the directive. They build on Anthropic’s earlier Claude Mythos Preview, which demonstrated strong capabilities in identifying software vulnerabilities as part of the company’s Project Glasswing cybersecurity initiative. The new models were tested with government agencies prior to release and received initial approval for deployment, according to a person familiar with the process.

Anthropic described the government’s sudden concern as focused on a “potential narrow, non-universal jailbreak,” where a user might bypass safeguards to ask the model to analyze and fix flaws in a specific codebase.

But the company has pushed back strongly in a statement. It said: “We disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people. If this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers.”

Anthropic characterized the dispute as a “misunderstanding” and said it is working to restore access “as soon as possible.”

Cybersecurity Community Pushes Back

The restrictions have drawn criticism from cybersecurity leaders across major U.S. firms. In a letter sent Sunday and signed by more than 50 security experts from companies including Nvidia and Adobe, the group argued that removing access to Anthropic’s models hampers defenders at a time when other AI tools are making it easier for attackers to find and exploit vulnerabilities.

The letter emphasized that Anthropic’s models are not uniquely dangerous and that China is advancing rapidly in its own AI capabilities. Taking the best defensive tools off the table, they warned, is “dangerous” for U.S. cybersecurity leadership.

This echoes Anthropic’s own position that the action creates market uncertainty and risks America’s AI edge without clear justification. CrowdStrike recently identified China-linked hackers as the biggest espionage threat to technology companies over the past year, adding weight to concerns about ceding ground in defensive AI.

Anthropic is now walking on a tightrope for a company that has positioned itself as a safety-focused leader, refusing certain military applications and limiting initial rollouts of powerful models like Mythos. As it scales commercially, with a valuation nearing $965 billion and a confidential IPO filing underway, it faces growing pressure to balance ethical commitments with national security expectations.

The Trump administration’s approach appears to reflect broader concerns about dual-use AI technologies that could be repurposed for offensive cyber operations. At the same time, the swift backlash from the cybersecurity community underscores fears that overly broad restrictions could weaken America’s overall defensive posture against sophisticated state actors.

Analysts note that Anthropic’s willingness to engage directly with officials on Monday suggests both sides are motivated to find a resolution. A productive outcome could ease tensions and allow the models back into circulation with enhanced safeguards. Failure to resolve the issue quickly, however, risks further straining relationships at a time when U.S. AI leadership is seen as strategically vital.

However, the dispute is largely seen as a microcosm of larger challenges facing the AI sector. As models grow more capable, the line between beneficial tools and potential national security risks becomes harder to draw. Regulators and companies are still developing frameworks for responsible deployment, and cases like this will help shape how those frameworks evolve.

Canadian fintech company Nuvei has agreed to acquire cross-border payments specialist Payoneer in a $2.75 billion all-cash transaction, adding to the intensifying battle among payment firms to capture the next wave of growth in global e-commerce, stablecoin transactions, and AI-powered digital commerce.

The deal values Payoneer at $7.40 per share, representing a premium of about 44% to its closing price on June 8, before reports emerged that the two companies were in advanced merger discussions. Payoneer’s shares rose following the announcement, reflecting investor confidence in the transaction and the rationale behind the combination.

The acquisition marks one of the most significant fintech deals of the year and comes as payment companies seek scale amid rapid changes in how businesses and consumers move money across borders.

At its core, the transaction combines two complementary businesses rather than overlapping competitors. Nuvei has built its reputation around merchant payment processing, helping businesses accept payments across multiple channels and markets. Payoneer, meanwhile, specializes in enabling businesses, freelancers, and marketplace sellers to send, receive, and manage funds internationally in multiple currencies.

The combination would create a payments powerhouse expected to generate roughly $3 billion in annual revenue while processing more than $500 billion in annual payment volume, placing it among the largest independent players in global digital payments.

The acquisition gives Nuvei immediate access to one of the most valuable segments of the digital economy: cross-border commerce.

Payoneer has established deep relationships with some of the world’s largest online marketplaces, including Amazon, Walmart, eBay, and Airbnb. These platforms depend on seamless international payment infrastructure to facilitate transactions between buyers and sellers across multiple countries.

As global e-commerce expands and more small businesses participate in international trade, the ability to move money efficiently across borders is becoming increasingly important. The deal also arrives as digital commerce is being reshaped by artificial intelligence. AI-powered agents are expected to automate procurement, payments, and international transactions, creating demand for payment networks capable of operating globally and in real time.

By combining Payoneer’s cross-border network with Nuvei’s merchant acquiring capabilities, the merged company aims to position itself at the center of this emerging ecosystem.

Stablecoins Emerging As A Major Growth Opportunity

Another significant driver behind the acquisition is the growing adoption of stablecoins. Digital-dollar payment systems have gained momentum globally as regulators become more accepting of blockchain-based settlement networks. Payment firms view stablecoins as a tool for reducing settlement times and lowering transaction costs in international commerce.

The merged company is expected to be particularly well-positioned to capitalize on this trend because Payoneer already has extensive international regulatory approvals and payment infrastructure, while Nuvei brings merchant relationships and payment acceptance capabilities.

Industry analysts believe stablecoins could become one of the most disruptive forces in payments over the next decade, particularly in emerging markets where traditional banking systems remain fragmented or expensive.

One of Payoneer’s most valuable assets may not be its technology but its regulatory footprint. The company operates under numerous licenses and regulatory approvals across key jurisdictions, allowing businesses to hold, send, and receive funds in multiple currencies.

Benchmark analyst Mark Palmer said the transaction’s appeal stems from combining “complementary halves of the payments stack.”

He added that Payoneer’s extensive regulatory infrastructure enhances the attractiveness of the acquisition.

Importantly, analysts expect antitrust concerns to be limited because the companies largely operate in different segments of the payments ecosystem.

“Regarding regulatory approval, antitrust risk appears manageable because the businesses are largely complementary and there is no meaningful horizontal overlap likely to attract scrutiny,” Palmer said.

That assessment may help smooth the path toward completion, although the transaction still requires shareholder approval and regulatory clearances in multiple jurisdictions.

Part of Broader Fintech Consolidation

Fintech companies are increasingly discovering that scale matters as competition intensifies from traditional banks, payment giants, and technology companies entering financial services. Rising compliance costs, increasing cybersecurity requirements, and growing demand for global payment networks are encouraging firms to seek mergers that expand their reach and customer bases.

The trend is especially pronounced in cross-border payments, where companies are racing to establish global networks capable of supporting e-commerce, digital marketplaces, gig-economy workers, and AI-driven business transactions.

The deal is seen as further evidence that investors remain willing to finance large strategic transactions despite higher borrowing costs and economic uncertainty. A consortium including BMO Capital Markets, RBC Capital Markets, Barclays, UBS, and Wells Fargo has committed financing for the transaction.

The acquisition is expected to create a company positioned to benefit from several long-term trends simultaneously: the continued expansion of global e-commerce, growing adoption of stablecoins, rising demand for cross-border financial services, and the emergence of AI-powered commerce.

The transaction is expected to close in mid-2027. By then, the payments industry could look very different from today.
