Anthropic said it suspended access to its Fable 5 and Mythos 5 AI models after receiving a US government export control directive citing national security concerns.In a statement posted Friday, Anthropic said it received the directive at 5:21 pm ET, instructing it to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. Anthropic abruptly disabled the models for all users in order to ensure compliance. It said all other Anthropic models, such as Opus 4.8, are not affected. “We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users,” the firm said. The directive comes just days after Anthropic released Fable 5 and Mythos 5, two powerful AI models built on top of Mythos Preview, a general-purpose language model that the company previously said had found thousands of vulnerabilities in critical software. Anthropic said the government did not provide specific details about the alleged threat, but said it believes authorities are concerned about a possible “jailbreak” method capable of bypassing Fable 5’s safeguards.Related: AI researcher claims he’s already bypassed Anthropic’s Fable 5 guardrails“To date, the government has only given us verbal evidence of a potential narrow, non-universal jailbreak, which essentially consists of asking the model to read a specific codebase and fix any software flaws,” said Anthropic. A non-universal jailbreak is a far lower threat than a “universal jailbreak,” a method to broadly bypass a model’s safeguards, it explained. “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,” it added. Anthropic said it believes the government order is a result of a misunderstanding and is working to restore access for users as soon as possible.

Crypto trading platforms Bybit, Binance, Bitget Wallet and MEXC canceled their tokenized SpaceX IPO campaigns as SpaceX went public on the Nasdaq on Friday. SpaceX’s IPO, which was reportedly more than four times oversubscribed, raised $75 billion as it became a publicly traded company. SpaceX shares opened for trading at $150 on Friday, up from its IPO price of $135. It closed the day at $161.11, valuing the company at over $2 trillion. However, major crypto platforms offering tokenized access to the IPO were unable to fulfill demand for SpaceX allocations, with several blaming Kraken-owned xStocks’ inability to deliver the underlying assets. The failed campaigns marked a setback for crypto platforms seeking to give their users high-demand public offerings for the first time. Bybit, which was offering tokenized access to SpaceX through its new Bybit IPO Express, was one of the first to announce the cancellation. “Due to xStocks’ inability to deliver the underlying assets, no SpaceX allocations were received. As a result, subscribed users will not receive SpaceX allocations.”Binance’s SpaceX tokenized IPO campaign, which attracted over $557 million in USDC deposits, said it was unable to proceed to the campaign due to “circumstances outside of our control.” Binance Wallet was also relying on xStocks. Source: Changpeng ZhaoBitget Wallet and MEXC also said they would be refunding affected users after being unable to secure an allocation of xStocks’ tokenized SPCX. Related: Bitcoin surfs SpaceX IPO at $64K as trader warns key BTC price support may crumble“It’s disappointing that this didn’t work out in the end.

Strategy watchers were not disappointed on Sunday as executive chairman Michael Saylor took to social media to signal pending news on changes in the company’s Bitcoin holdings, hours ahead of the final tally of shareholder votes on a proxy measure that would see the company pay dividends twice a month on its preferred STRC shares.“A good time to add more dots,” was the message Saylor posted on X.com along with a bubble chart tracking Strategy’s Bitcoin (BTC) purchases over the past nearly six years. That chart, from Iceland-registered StrategyTracker.com, has been consistently posted by Saylor in the days ahead of news of a purchase by the biggest publicly traded Bitcoin holder.By mid-afternoon on Sunday, Michael Saylor’s X post had 2.3 million views.

Rumors otherwise are just rumors.”Should any purchases be announced in the coming days, they will likely reflect that the Bitcoin treasury company bought at or below the average cost of previous BTC purchases. That average cost of Strategy’s current holdings of 843,706 Bitcoin is $75,701 apiece. However, the biggest cryptocurrency by market cap has lost 16.6%% of its value in the past seven days, trading at about $62,153 at the time of publication, according to CoinMarketCap data.Last week, Strategy announced that it has repurchased some corporate debt, temporarily pausing its Bitcoin accumulation. That sent a chill to the market as traders feared that the company could be forced to liquidate some of its BTC holdings to fund the buybacks. Related: Strategy’s leveraged Bitcoin model has faced its first stress test: GrayscaleDown to wire on STRC dividend change proxy voteStrategy shareholders have been asked to approve a change in dividend payments on STRC, to semi-monthly instead of monthly.

It should increase the Sharpe ratio. It provides more entry and exit points. There’s 24,000 companies that pay a quarterly dividend. 176 pay monthly. We’ll be paying twice a month.

US Federal Reserve governor Christopher Waller said Sunday that the growing use of dollar-backed stablecoins could bolster the global influence of US monetary policy.Waller told participants at the 32nd Dubrovnik Economics Conference that countries that increasingly rely on stablecoins backed by the US dollar may effectively import US monetary conditions, Bloomberg News reported Sunday.“I’ve always just looked at ​stablecoins as a payment instrument; there’s nothing evil about it, nothing dangerous about it,” Waller said. “They ​are just bringing competition into the payments world,” Reuters reported.Source: The 32nd Dubrovnik Economic ConferenceA contrary view was presented by his fellow presenter, Bank of England policymaker Megan Greene, who said stablecoins could fade from view in a matter of a few years. She said:“I think tokenized deposits are probably going to take over from stablecoins and ​five years from now, I suspect we might wonder why we were talking about stablecoins.”Both were part of a panel discussion titled “Stablecoins and monetary policy” at the annual Croatian National Bank event.A long-time skeptic of central bank digital currencies (CBDC), Waller said that enthusiasm for CBDCs has faded among many central banks. BoE’s Greene disagreed.“I like to think of it as a massive race between the tortoise, the hare and the rhino.” Greene said. “The tortoise is the central ⁠bank ​digital currency …the hare is stablecoins and the rhino is tokenized ​deposits. We’ll probably end up with all three, but if I had to put money in one … it would be the ​rhino, tokenised deposits, which I think will probably take off,” Reuters reported.Related: ECB pushes back on euro stablecoin proposals, citing financial stability risksStablecoin policy stymies US crypto legislationDebate over US policy on stablecoin yield has stymied progress on the US Digital Asset Market Clarity Act under consideration in the US Senate. The crypto market structure bill is one of the most significant pieces of crypto regulations in the US, but it is unclear if it will be signed into law in 2026 due to opposition from the banking lobby and the looming US midterm elections.The CLARITY Act, which aims to establish a federal regulatory framework for digital assets passed out of the Senate Banking Committee on May 15 after months of debate between banks and the crypto industry over stablecoin yield provisions.
