US stocks gained on 12 August after new inflation figures showed consumer prices rose 3.4% year on year in July, down from 3.5% in June.

The Nasdaq Composite rose about 0.5%, while AI-linked companies recorded stronger gains. CoreWeave jumped more than 18% and IREN gained over 7%. Both companies previously operated in crypto mining before expanding into artificial intelligence infrastructure.

SpaceX $SPCX is now up 40% over the past 5 days, adding $530 billion to its market cap.

SpaceX also joined the rally, with its shares rising 11% to $148. The move pushed its market capitalisation to around $1.88 trillion, adding about $127 billion based on the share-price increase.

Matthew Sigel, head of digital assets research at VanEck, highlighted the scale of the gain on X.

“$SPCX has added a whole $NBIS + 2 $CRWVs + an $IREN in market cap today,” he wrote on 12 August.

At the time, CoreWeave had a market value of about $58.5 billion, meaning two CoreWeaves were worth roughly $117 billion. Nebius stood at around $62 billion, while IREN was valued at approximately $14 billion. Together, the companies were worth about $193 billion, roughly matching SpaceX’s one-day increase in market value.

The SpaceX rally comes two months after its 12 June initial public offering. The company reported second-quarter revenue of $7.81 billion, up 92% from a year earlier, while adjusted EBITDA increased 191% to $3.5 billion.

SpaceX also held 18,712 Bitcoin worth about $1.1 billion as of 30 June. The company did not sell any of its reported Bitcoin holdings during the period.

Could SpaceX’s enormous valuation make its future share-price movements increasingly influential across global markets?
