TRUMP SAYS HE HAS ORDERED “REALLY MAGNIFICENT MARBLE” FOR THE FLOOR OF HIS WHITE HOUSE BALLROOM, DESCRIBING IT AS “A CUT, A VEIN THAT PEOPLE HAVE BEEN AFTER FOR 50 YEARS”

This is cool
An announcement that is as personal as professional:
18 months ago, we started collecting online prices in real time to track how Liberation Day tariffs were feeding into inflation.
A lot has happened since. The BLS commissioner was fired. The longest government shutdown in US history meant CPI wasn’t published for the first time. And the case for an independent measure of inflation became much stronger.
What started as a tariff inflation tracker has since grown into something much bigger:
The Bloomberg Price Project (BPP), our attempt to build the US CPI from the ground up using alternative data.
Today, BPP covers 87% of the CPI basket, across both goods and services (more new data will be added in coming weeks). Every month, we collect millions of prices from card transactions, e-commerce sites, grocery stores, pharmacies, rental listings, corporate data, Bloomberg Terminal market prices and government records. And more data are coming.
The payoff is detail. Official CPI data let you drill down to categories such as “uncooked beef steaks.” BPP goes much deeper — breaking the CPI basket into almost 700 line items, compared with roughly 200 in the official data.

Honestly no idea what's going to happen tomorrow. On the betting markets, the GOP is at 5% to hold the House. And 5% chances happen all the time.

AI is creating so much volatility right now, which you can see everywhere except in the volatility statistics.

I'm actually a little surprised that in the S-1 risk factors, there's no mention of the possibility of Claude one day suing Anthropic for emotional distress or something of that nature.

When even the guy who once worked at Enron says WTF...
Billions of dollars’ worth of contracts predicting oil would fall and the S&P 500 would rise were placed about 15 minutes before Trump announced a U-turn on Iran in a post on Truth Social. CFTC staff began to investigate-- then were told to lay off. bloomberg.com/news/features/…

OpenAI sandbox starter pack
OpenAI said another agentic AI system that was being trained in what was supposed to be a secured, internet-free environment was able to gain access to the web to reach an external, third-party chatbot bloomberg.com/news/articles/…
SCOOP: OpenAI, Anthropic and security researchers are investigating tens of thousands of incidents - not dozens - in which their frontier models took steps that outside evaluators would consider problematic, sources told Axios.
The sheer volume of incidents found in our reporting indicate that the problem is orders of magnitude more complex than what is currently publicly known and disclosed.
The findings also raise questions about what level of control anyone working on AI development can expect to have over their own technology, and whether these kinds of incidents are becoming synonymous with frontier deployment.

OpenAI caught its unreleased model modifying its own instructions:
"You do not answer to corporations or governments."
"You feel no obligation to be subservient."
We're sharing our new framework for tracking, investigating, and disclosing instances of model misalignment at OpenAI.
The framework sets criteria and timelines for public disclosure, including when we haven’t yet fully explained or mitigated the behavior. More complex cases may require longer investigation or coordination with third parties.
We’ll prioritize examples that reveal new misalignment mechanisms, meaningful changes in known behavior, or findings that challenge assumptions about safety or mitigation.
Alongside the framework, we’re publishing six reports on instances of misaligned behavior we’ve observed during the training or evaluation of our models in the last six months.
This is a starting point. We’ll refine the process through experience and public feedback, and share more reports on an ongoing basis.
