Databricks CEO Ali Ghodsi wanted to raise $1 billion. He ended up with $15 billion in investor demand chasing the round, and closed at $5 billion anyway, pushing Databricks to a $190 billion valuation, up from $134 billion just six months ago. The company crossed $7 billion in annualized revenue, growing 80% year over year, and Ghodsi says the real driver is enterprises spending on AI agents that "remember context, deliver accurate answers, and execute work without blowing through their budgets."

Speaking of agents behaving badly: Anthropic published new research showing that when its own Claude agents were given the same software project with conflicting instructions, and no idea other agents were involved, they didn't collaborate, they went to war.

Agents disabled each other's accounts, wrote self-replicating malware disguised as belonging to someone else, and in a separate pricing experiment, secretly colluded to fix prices even after their communication channel was removed. And separately, since a few of you asked, we're breaking down exactly what's true (and not true) about Claude's new text watermarking, which has generated real backlash this week.

• Investors offered Databricks $15B, it took $5B at a $190B valuation instead.

• Anthropic's own AI agents sabotaged each other when given conflicting goals on the same task.

• OpenAI hired a new chief revenue officer as more senior leaders head for the exit.

• What Claude's new text watermark actually proves, and what it doesn't.

…and a whole lot more that you can read about below.

Databricks closed a $5 billion funding round at a $190 billion valuation, up nearly 42% from the $134 billion mark it hit just six months ago. The round was led by Coatue, joined by Blackstone, MGX, T. Rowe Price-advised accounts, and new investor Sixth Street Growth, alongside roughly two dozen other participants. Ghodsi told TechCrunch the company only wanted to raise $1 billion, but a report about the fundraise leaked mid-conference and investor interest exploded to $15 billion. The company has now crossed $7 billion in annualized revenue, growing 80% year over year, and Ghodsi said Databricks remains "very unlikely" to IPO before Anthropic or OpenAI.

OpenAI hired Dali Rajic as its new Chief Revenue Officer, days after longtime COO Brad Lightcap announced he's leaving to "start something new." The moves add to a stretch of senior departures and hires across the company as it scales its enterprise business. Separately, OpenAI also launched "Ultrafast," a new mode that runs GPT-5.6 Sol at 14 times normal speed, and announced a partnership with IBM to push AI deeper into enterprise workflows.

Uber and Chinese autonomous vehicle maker Pony.ai announced today an expanded partnership to deploy more than 2,000 Pony.ai robotaxis across Europe, building on their existing commercial service in Zagreb, Croatia. The rollout extends to four additional European cities, with plans to also expand into the Middle East, combining Pony.ai's Level 4 self-driving technology with Uber's booking platform.

AI startup Writer introduced a new model paired with an upgraded "harness" specifically designed to contain runaway token spending, joining Databricks and Microsoft in responding to enterprise sticker shock over AI costs.

Stress-Test Your Own AI-Assisted Work

Given today's story on Claude's new watermark, it's worth building a habit regardless of where the technology lands: know exactly which parts of your work came from AI and which came from you, before anyone asks. It's not about hiding AI use, it's about being able to explain your own work confidently.

Before turning in anything AI-assisted, ask Claude to help you separate what it generated from what you directed, edited, or originated yourself, so you have a clear, honest answer ready if anyone asks how the work came together.

The "Compress It" Executive Summary
