(Reuters) -Artificial intelligence startup CoreWeave's shares closed up 42% at $52.57 on Tuesday, their third day of trading, above their initial public offering price of $40. At close, the company added more than $7 billion to its market value.

Shares of CoreWeave were recently down about 9% to under $37, below the $39 at which it opened trading last week. Part of the pullback is likely due to broader market concern, with investors jittery about what might happen later this week with the Trump administration tariff policy .
