This earnings season, all eyes are on cloud revenue growth

AI computing demand is generating huge revenue streams for hyperscalers, but the market is closely watching the pace of growth, which is slowing.

This week, we’ll get an update on how many billions the cloud giants pulled in last quarter. AI has created an insatiable hunger for more cloud computing, and Amazon, Google, and Microsoft are racing to serve up computing capacity as fast as they can build the massive new data centers needed to catch up with demand.

As a result, the tens of billions of revenue that these tech titans are pulling in keeps going up.

At the same time, their customers are struggling to figure out a viable business model for the AI services they’re developing, and chatter about a possible AI bubble is getting louder.

That means as these tech giants report earnings this week, investors will be scrutinizing more closely how much money these cloud computing businesses are generating, and comparing the pace of growth.

Last quarter, Amazon CEO Andy Jassy tried to explain his company’s AWS cloud unit’s relatively slow revenue growth of 17.5% to analysts, saying that a small number of huge customers tend to spend in bursts, which will result in uneven growth. But overall, Jassy was bullish on the cost- and energy-efficient Trainium chips that Amazon is filling its data centers with.

Microsoft will update investors on Azure’s growth, its flagship cloud business and part of the “intelligent cloud” unit, which includes public, private, and hybrid server products and cloud services. Last quarter, Azure had revenue growth that was the envy of the industry, increasing 39% year on year. There was so much demand, the company had a backlog of $368 billion in signed contracts.

While smaller than Amazon or Microsoft, Google Cloud revenue grew a healthy 31.7% year on year. Google has recently been pitching its own custom chips to customers, putting it head-to-head with Nvidia.

Prediction markets have, predictably, been given a boost by the summer of sports

Major platforms like Kalshi and Polymarket have seen huge upticks in users of late, thanks in no small part to what’s felt like a recent sporting smorgasbord, with major competitions across hockey, basketball, and soccer soaking up fans’ time (and spending, clearly) at the outset of summer.

While gaming industry groups may not like it, there’s been a huge change in the methods people are using to put money on the big games, with everyone from fortunate NYC bar owners, to a far less fortunate Spanish supporter, turning to prediction markets to try and turn their sports know-how into cold, hard cash.

According to a new report from Adam Blacker for apptopia, that shift might have been even more seismic than imagined in the wake of the NBA and NHL finals and around the 2026 World Cup kicking off.

Anthropic pulls Fable and Mythos access worldwide after Trump administration bars their use by foreign nationals

Only days after releasing two versions of its next-gen AI model, Anthropic has disabled them for users worldwide.

Anthropic says it received a Friday night order from the Trump administration to suspend access to the models for any foreign national (anywhere in the world) — a group that included some Anthropic employees. In response, the company turned off access to everyone.

Last week, the company released to the public its much-anticipated Claude Fable 5 model (and its restricted version Claude Mythos 5, which is still being tested with trusted partners). Anthropic said in a blog post announcing the action that officials cited national security concerns with the new models, while offering few specific details.

The post said that the government gave the company “verbal evidence of a potential narrow, non-universal jailbreak” of the public Fable 5 model. A jailbreak is a means by which users can evade restrictions built into the code to unlock prohibited functionality. Anthropic downplayed the significance of the attack, and said other major models, such as OpenAI’s GPT-5.5, could also be affected by the technique described.

Fears of these first Mythos-class models being misused are running high, after Anthropic warned the cybersecurity world in May that the advanced cyber capabilities of Mythos have rapidly discovered thousands of vulnerabilities in ubiquitous software, leading to the decision to restrict the full version of the model to a close group of trusted partners for testing.

This morning, Axios reported that Anthropic technical staff have flown to Washington to meet with White House officials to resolve the issue.

The Wall Street Journal is reporting that the Trump administration’s decision to take action against Anthropic was prompted by discussions that Amazon CEO Andy Jassy had with officials, including Treasury Secretary Scott Bessent. According to the report, Amazon researchers said they had been able to evade some of Fable 5’s security restrictions using specific prompts. Amazon is a major investor in Anthropic.

Anthropic is currently suing the US government to fight the Pentagon’s blacklisting of the company on national security grounds.
