Semiconductor maker Micron, squeezed by declining demand for personal computers, said it would reduce its workforce by about 10%, while also suspending bonuses. That amounts to a few thousand staffers, as a recent filing showed the company had about 48,000 employees. Micron announced the decision as it posted its latest quarterly results and forward guidance, both of which fell below Wall Street’s expectations. “In the last several months, we have seen a dramatic drop in demand,” CEO Sanjay Mehrotra said in prepared remarks.

If you’ve been following the collapse of crypto exchange FTX and the prosecution of its founder and mastermind, Sam Bankman-Fried, you’ve probably been wondering why we haven’t heard from Gary Wang and Caroline Ellison. And if you suspected they were cooperating with the feds, you were right. On Wednesday night, federal prosecutors revealed that Wang, a co-founder of FTX, and Ellison, who was co-CEO of sister firm Alameda Research, had agreed to plead guilty to federal crimes while working with authorities on the case of the fallen crypto firm. The news broke while Bankman-Fried, aka SBF, was on a flight from the Bahamas to the United States to face his own prosecution.

Ukrainian President Volodymyr Zelenskyy took Washington by storm Wednesday in what’s been hailed as a triumphant visit. It was his first known excursion beyond Ukraine’s borders since Russia launched its unprovoked invasion on the former Soviet country in February. Zelenskyy’s trip to the U.S. capital included a meeting and a press conference with President Joe Biden at the White House and a rousing, 32-minute address to a joint session of Congress. “Thank you for both financial packages you have already provided us with and the ones you may be willing to decide on,” he told lawmakers, who are set to approve more than $44 billion in new aid for Ukraine. “Your money is not charity. It is an investment in global security and democracy, that we handle in the most responsible way.”

Another day, another grim scrap of data from the housing market. Home sales tumbled a deeper-than-expected 7.7% in November from October, marking the tenth consecutive month of sales declines. The sales reflect contracts signed in September and October, when interest rates had peaked before coming down a bit in recent weeks. (Although they’re still about double what they were at the beginning of this year.) “In essence, the residential real estate market was frozen in November, resembling the sales activity seen during the Covid-19 economic lockdowns in 2020,” said Lawrence Yun, the chief economist for the National Association of Realtors.
