- Micron Technology (MU) shares are up 3.1% on Wednesday, after D.A. Davidson raised its price target on the memory chipmaker to a Street-high view of $3,000, seeing long-term tailwinds related to AI. Analyst Gil Luria recently met with Micron’s management team, and “concluded that investors are early in their journey of understanding MU’s value and believe that journey will lead them to assigning a far higher multiple”

- Webull (BULL) shares fell as much as 24%, the most since April 2025, after CNBC reported that the US House Select Committee on China is set to release a report on Wednesday that Webull is tied structurally to China’s government, raising national security concerns.

- A measure of SpaceX’s (SPCX) credit risk surged to a fresh high and the company’s bonds weakened in the secondary market on Wednesday, following reports the company is in talks with banks and investors to raise $40 billion to buy chips from Nvidia Corp. The price of five-year credit default swaps on the company’s debt rose as much as 0.167 percentage point to around 197.6 basis points a year, according to ICE Data Services, which is the highest intraday level since the swaps started actively trading in June. SpaceX is looking to raise $40 billion in what would be among the biggest-ever debt financings for the AI buildout, with the company’s fundraising discussions in an early stage and could end without a deal being completed, according to people familiar with the matter.
