Nvidia completed its climb, passing Microsoft to become the most valuable public company on earth — a title held by a chipmaker for the first time in the modern market era. The week's cautionary tale came from the auto industry: a ransomware attack on CDK Global, the software backbone for roughly 15,000 dealerships, froze car sales across the country and dragged on for days, another demonstration that a single vendor can be a national single point of failure. And Apple, eleven days after unveiling Apple Intelligence, said its marquee AI features won't launch in the EU this year — blaming the Digital Markets Act's interoperability requirements.
AT&T suffered its second high-profile incident of the year when customers spent hours unable to call people on other carriers — a failure of the unglamorous interconnection plumbing that makes separate networks feel like one phone system. The week also delivered an early warning that would define the summer: security researchers tied a wave of Snowflake cloud-account breaches to infostealer malware and missing multi-factor authentication, with Ticketmaster and Santander already implicated. And Nvidia blew past $3 trillion in market value, overtaking Apple as the AI trade rewrote the market's hierarchy. The FCC, meanwhile, proposed the first real rules for securing the internet's routing system.
OpenAI revealed Sora, a text-to-video model whose photorealistic minute-long clips instantly reset assumptions about synthetic media — and about how much bandwidth and compute the AI era will consume. Nvidia's market value sailed past Alphabet's, making the chipmaker the third most valuable U.S. company behind only Microsoft and Apple, days before earnings that would justify the climb. And Cisco — the networking giant of the last internet buildout — announced it would cut 5% of its workforce, a stark reminder that the infrastructure boom is not lifting all boats equally.
