NEW: We’ve spent months reporting on a Chinese intelligence effort to penetrate the Federal Reserve. It’s a fascinating and important saga, revealing the lengths that Chinese spies are willing to go to get any scrap of information about the Fed. It features lies, betrayal, nude photos, extortion, false identities and document leaks. And it doesn’t end at all the way you might expect: cnbc.com/2026/09/30/john-rog…

Big escalation tonight from the White House in the U.S.-Canada trade war. Three parts to this:
1) Expanding the list of goods subject to 50% tariffs
2) Saying that 232 tariffs now stack on top of them
3) Escalating some of the goods already facing 50% tariffs to outright bans

Some brutal figures from Treasury's latest monthly statement, for the fiscal year to date
—The U.S. deficit is at $1.8T, larger than the deficit for all of last year
—$1.2 *trillion* spent on interest on the debt
—Corporate tax receipts down 18%
And still two months left to go!

AI’s costly buildout complicates the Fed’s inflation fight: deep dive with @mattbpete 💸
Silicon Valley leaders have hyped the deflationary and productivity effects of the AI boom. In the near term, none of those economic dreams are close to being realized..
Instead, AI is hitting a wall of corporate inertia as it spreads out into the economy — causing some near-term inflation and producing little evidence of a sustained productivity boom.
It poses a dilemma for the Fed, which needs to make decisions about how to manage inflation. More on @CNBC this morning:

New with @ashleycapoot 📰
OpenAI and Anthropic have been the principal beneficiaries of the spend-at-all-costs mentality, which has fueled their exponential growth rates and pushed both of the AI model leaders to valuations approaching $1 trillion.
Now, as they gear up for potentially historic IPOs — both filed confidentially in early June — the mood around AI is shifting, and business leaders are no longer willing to throw money at Anthropic or OpenAI without a clear picture of a return on their investment.
“Current growth rates for Anthropic and OpenAI are the fastest they will ever be, which is mostly a matter of basic math,” Gil Luria, an equity analyst covering tech companies at D.A. Davidson, told CNBC. “That is a good reason to go public now, as is the concern that some of their largest enterprise customers may start limiting their out-of-control token spend.”
