Micron slumps on report Samsung’s new memory chip passed Nvidia’s reliability tests

Shares of Micron are getting slammed on Wednesday after Seoul Economic Daily reported that Samsung Electronics’ new memory chip “passed reliability testing” from Nvidia and is poised to enter the preproduction stage.

Per SE Daily, these HBM4 chips would be used in Nvidia’s Rubin architecture, the successor to Blackwell.

Micron has been significantly expanding its market share in the high-bandwidth memory chip market at Samsung’s expense, and the South Korean company’s renewed progress — with Nvidia’s blessing — threatens to eat away at some of that.

SpaceX gets a wave of bullish ratings from Wall Street analysts

SpaceX received more than a dozen positive analyst calls on Tuesday — including from major Wall Street banks — as they initiate coverage on Elon Musk’s space and AI company.

SpaceX went public on June 12 at a $2.2 trillion valuation, the largest debut in history. While the company hasn’t yet posted a profit, it seems to have convinced Wall Street that it will get there and grow its valuation on the way.

Of the at least 17 analysts that gave a rating on Tuesday, all but one gave it a “buy” or “outperform” rating. MoffettNathanson was "neutral."

The ratings come as SpaceX joined the Nasdaq 100 index, a benchmark tech-heavy basket of companies that underpins millions of portfolios. The inclusion adds built-in demand for the stock from index funds and ETFs.

Still, SpaceX fell more than 5% on Tuesday amid a broader sell-off, and is currently effectively flat from its opening price of $150 a share.
