What happened
The S&P 500 (SPX) rose 0.58% to 7,757 on Wednesday as upbeat SpaceX and Super Micro results revived AI demand hopes, with the Nasdaq up 1.05% and the Dow up 0.69%. SpaceX (SPCX) jumped 7.8% to $159.31 after reporting $14.6 billion in quarterly sales, up 161% from a year ago, and its first profit as a public company. Server maker Super Micro raised its quarterly sales forecast by $4 billion to $18.5–19.5 billion, citing demand for AI computers. Netflix slid after a weak forecast.
Why it matters
The S&P 500's 0.58% gain matters because many retirement and savings funds track the index. It shows investors again believe AI spending is paying off, after worries that companies were spending too much on data centers. Tech stocks have led the market this year, so strong AI results can lift funds that hold them, while a weak report can drag them down.
