Space Exploration Technologies Corp.

(NASDAQ:SPCX) is going all-in on Nvidia Corp.

(NASDAQ:NVDA), and for CNBC's Jim Cramer, the announcement reinforces his long-standing bullish thesis.

Earlier this year, Elon Musk had indicated that his companies, SpaceX and Tesla (NASDAQ:TSLA), would use both AMD and Nvidia chips.

The move to an Nvidia-exclusive strategy underscores Nvidia's continued dominance in AI accelerators, even as rivals have won major customers and attempted to gain share.
