Anthropic expanded the reach of its Mythos AI model to an additional 150 companies across 15 countries but stated each will need to meet its security requirements before they gain access.

Anthropic introduced its Claude Mythos model on 7 April, under the auspices of its Project Glasswing to a limited number of technology companies including Amazon Web Services, Apple, T-Mobile US, AT&T, Nvidia and Google, instead of making it publicly available.

The company stated the new cohort features industries which were underrepresented in the first batch. It now includes power grids, water systems, healthcare networks, communications providers, and hardware manufacturers.

Anthropic stated for most of the Project Glasswing partners, a successful cyberattack on their codebases could affect more than 100 million people.

It also noted many of the new partners are vendors, companies or nonprofits that maintain codebases which are relied upon by numerous organisations around the world, including governments.

The company expects within six-to-12 months, many other AI developers will have models comparable to Mythos Preview and stated, “they could release them without safeguards that prevent misuse”.

Results from the first cohort are already in. Project Glasswing partners have collectively surfaced more than 10,000 high-or critical-severity security vulnerabilities in the first few weeks.

The AI player stated the bottleneck in cybersecurity is now verifying, disclosing, and patching the large numbers of vulnerabilities which Mythos-class models can surface.

It noted many of Project Glasswing’s partners now use the model to write patches, as well as for pre-release checks which prevent vulnerabilities from appearing in the first place.

The expansion came a day after the Anthropic stated it will start offering Mythos access to the European Union’s cybersecurity division.

It also confidentially filed its initial public offering prospectus with the US Securities and Exchange Commission ahead of rival OpenAI.

EchoStar elected to defer approximately $183 million in cash interest payments due on debt held by its Dish DBS Corporation subsidiary, citing a preference to conserve liquidity while it awaits the closing of its spectrum deal with AT&T.

According to a statement, the missed payments span three tranches of Dish DBS notes: around $72.2 million on 5.25% secured notes due 2026, $71.9 million on 5.75% secured notes due 2028 and $38.4 million on 5.125% unsecured notes due 2029.

The company stated it skipped the payments deliberately to preserve cash while it waits for the AT&T deal to close, implying it does not intend to make the payments within the grace period.

The notes were part of the broader debt load accumulated by Dish Network over years of spectrum acquisitions and satellite operations, debt which became central to EchoStar’s financial stress and its motivation to complete the $23 billion AT&T deal.

Under the terms of the relevant indentures, the non-payment is classed as a default, though EchoStar has a 30-day grace period before it formally constitutes an event of default.

EchoStar said both the Federal Communications Commission (FCC) and the US Department of Justice granted regulatory approval for the AT&T transaction, though the FCC’s sign-off is not yet final. The company noted the closing remains subject to the satisfaction or waiver of additional conditions.

The deal, announced in August 2025, will generate net proceeds of $20.25 billion according to EchoStar’s filing, reflecting adjustments and transaction costs applied to the gross figure.

AI player Anthropic confidentially submitted paperwork for its proposed initial public listing ahead of rival OpenAI, while also giving the European Union’s cybersecurity body preliminary access to its Mythos AI tool.

The draft registration statement submitted to the US Securities and Exchange Commission gives the company the option to go public after the agency completes its review.

Anthropic stated the number of shares to be offered and the price have not yet been set.

News of the IPO move came the same day (1 June) Bloomberg reported Anthropic will give ENISA, the European Union’s cybersecurity agency, access to Mythos through Project Glasswing, an initiative which allows organisations to test Mythos’ capabilities before a wider release.

There are growing concerns among governments over the security implications of Mythos, which Anthropic released to some private companies in April.

Anthropic communicated the decision to the European Commission over the weekend.

EC spokesperson Thomas Regnier confirmed the development to Mobile World Live (MWL) followed several weeks of productive discussions.

 “We welcome the latest developments on potential future access,” he said. “This is the result of the Commission’s strong bilateral cooperation and engagement with Anthropic, a leading frontier AI company.”

The EC was careful to frame the moment not as a resolution but as a starting point to work with the US administration, Anthropic and additional AI companies such as OpenAI.

“This is a shared challenge, and we are intensifying our discussions with like-minded partners, including the United States,” Regnier said.

The plan is for ENISA to join Project Glasswing, the coalition Anthropic announced in April which includes Amazon, Apple, AT&T, T-Mobile US, Microsoft, Google, CrowdStrike, Nvidia and Palo Alto Networks, among others.

Meta Platforms reportedly acknowledged its controversial employee surveillance programme captures data from employees outside the US, raising fresh legal questions in Europe.

Reuters reported internal documentation it reviewed showed the company’s Model Capability Initiative (MCI) does capture data outside of the US.

MCI was introduced last month as a tool to record how US-based employees interact with their work computers by tracking mouse movements, clicks and navigation patterns across more than 200 apps and websites.

The goal of MCI is to use the employee-generated data to train AI agents capable of performing coding and white-collar tasks.

Meta told staff the programme is confined to US devices and stated safeguards are in place to protect sensitive information.

The news agency noted Meta acknowledged in a question-and-answer document provided to employees MCI will capture the contents of any emails or direct messages sent to US personnel, regardless of the sender’s ⁠location.

Meta spokesperson Dave Arnold told Reuters the company notified non-US employees the tool was running on the machines of US-based colleagues they might correspond with, describing the step as one of transparency.

A representative for Meta told Mobile World Live: “We’ve been clear that this tool is for US-based personnel only, and in the interest of transparency, we notified non-US employees that it was deployed on the computers of US colleagues they may email or chat with in the normal course of business.”

“We carefully considered and mitigated potential privacy risks in both the development and deployment of this tool, and we are committed to complying with applicable laws and regulations.” 

New regulatory exposure
Reuters stated the disclosure introduces new regulatory exposure in Europe, where technology companies are already fighting a series of heated legal battles over data collection.

Under the EU’s GDPR rules, the news site explained companies must establish a clear legal basis for processing personal data, disclose what is being collected and satisfy strict conditions around sensitive categories of information.

Kleanthi Sardeli, a legal expert at privacy advocacy group NOYB, told the news site even limited or incidental capture of EU employee data could put Meta in breach of GDPR rules.

A key question, she said, is whether data originally gathered for work communications can lawfully be repurposed to train an AI model.

The European Union (EU) is pressing for deeper talks with the US administration over advanced AI models, and at the heart of the conversation is Anthropic’s Mythos.

There are growing concerns among governments over the security implications of Mythos, which Anthropic released to private companies in April.

Its release triggered an immediate wave of concern when it surfaced the model could identify tens of thousands of software vulnerabilities at a scale no previous system had demonstrated.

The AI player introduced its Mythos model on 7 April, under the auspices of Project Glasswing, to a limited number of technology companies including Amazon Web Services, Apple, Nvidia and Google.

Anthropic expects to bring Mythos-class models to all customers in the coming weeks.

Bloomberg previously reported the EU made limited progress in securing access to details of vulnerabilities Anthropic’s Mythos AI model could reveal.

European Commission spokesperson Thomas Regnier told Mobile World Live (MWL) the agency has had several meetings with Anthropic to understand the capability of the model, its implications for the cybersecurity of the EU and Anthropic’s plan around Project Glasswing.

“We will keep discussing with the company the cyber capabilities and risks of its latest model,” he stated.

CNBC reported Anthropic has yet to grant the EU, its AI office or any government organisations outside of the US, aside from the UK’s AI Security Institute, preview access to Mythos.

Since August 2025, the European Commission’s AI Office has held regular technical meetings with Anthropic tied to the General-Purpose AI Code of Practice, to which the company is a signatory.

A spokesperson for the EC noted Mythos is not a one-off as a “new wave of powerful models are coming to the market”.

The EC stated parallel progress is being made towards releasing OpenAI’s GPT-5.5-Cyber to trusted EU entities.

The EC spokesperson told MWL it is intensifying discussions with the US, “particularly on the most advanced AI models, including those with cyber capabilities”.

“Cybersecurity is a shared priority and we have agreed to mutually recognise our respective standards in this area,” the spokesperson stated.  “On EU side, we are also stepping up our cyber defences through targeted investments in AI and supercomputing.”

The US Space Force (USSF) granted SpaceX a $4.1 billion contract to build a constellation of birds capable of detecting and tracking airborne threats globally, which signals a shift in how the military conducts battlefield surveillance.

The competitive Other Transaction Authority agreement, announced last week (29 May) by Space Systems Command, covers the space-based airborne moving target indicator (SB-AMTI) programme.

SB-AMTI architecture integrates advanced space-based sensors, secure and rapid communication links, and resilient ground processing.

The deal tasks SpaceX with fielding an initial satellite constellation by 2028, giving joint military personnel an early capability to close what officials describe as dangerous operational blind spots.

The driving force behind the programme is a growing recognition traditional airborne platforms for tracking moving targets are increasingly vulnerable. As adversaries field more sophisticated anti-access and area-denial systems, the Pentagon has concluded a persistent, space-based sensing layer is essential.

USSF acting portfolio acquisition executive for space-based sensing and targeting Colonel Ryan Frazier, said the shift to space gives joint warfighters continuous awareness of contested airspace in a way ground or airborne systems cannot match.

He noted development and integration work is beginning immediately to meet the programme’s accelerated timeline and address pressing national security demands.

USSF has assembled a multi-vendor pool which includes numerous companies selected through the Space Systems Command’s other transaction authority agreements announced at the Space Symposium in April.

The SB-AMTI award landed several days after the USSF confirmed a separate $2.29 billion contract with SpaceX to build the Space Data Network Backbone.

A Blue Origin New Glenn rocket exploded during a test, a potential blow to AST SpaceMobile and its launch schedule.

The New Glenn explosion yesterday (28 May) at Cape Canaveral in the US state of Florida will likely lead to lengthy investigations by the US Federal Aviation Administration (FAA) and NASA, which will sideline future launches.

In late 2024, AST SpaceMobile signed a multi-launch agreement with Jeff Bezos’ Blue Origin. It previously relied on SpaceX’s Falcon 9 rockets to launch its birds into orbit before attempting to branch out to the larger New Glenn models.

AST SpaceMobile has predicted an orbital launch cadence of roughly every one to two months this year through deals with multiple launch providers as it continues to target having approximately 45 birds in orbit by the end of 2026.

New Glenn’s seven meter-wide payload fairing is one of the few in the industry capable of accommodating the 2,400 square-foot phased arrays of AST SpaceMobile’s Block 2 BlueBird satellites, with the potential to carry up to eight per flight.

Fallout
“The New Glenn failure is a tough blow to AST which, due to the size of its satellites, has limited options for launch and New Glenn was by far the best option,” Chris Quilty, founder and CEO of research company Quilty Space told Mobile World Live (MWL), adding the company would now struggle to achieve its launch target for the year.

Tim Farrar, president at consulting company TMF Associates, told MWL the explosion has a “huge impact since this was the primary launch vehicle and it will take a year or more to rebuild the [launch] pad”.

“I think this pushes [AST’s] continuous commercial service back to 2028,” he added.

A representative for AST SpaceMobile stated the company’s near-term launches are unaffected.

“None of the missions planned for the next few months are scheduled with Blue Origin. Our satellites are designed to be launcher-agnostic, and we have agreements in place with multiple launch providers, giving us flexibility across our launch programme.”

BlueBirds 8, 9, and 10 are already at Cape Canaveral undergoing final processing ahead of a planned launch on a SpaceX Falcon 9 rocket next month.

A launch of AST SpaceMobile’s next-generation BlueBird 7 satellite from a Blue Origin New Glenn rocket last month fell short of the required orbit, resulting in its loss.
