CoreWeave Shares Slide 36% in October as Credit Signals Worsen

CoreWeave had a rough October. Its shares dropped 36% over the month, a steep decline for a company that has been closely watched as a bellwether for the AI infrastructure trade.

The selloff was not confined to the equity market. Credit default swap spreads on the company's debt have been widening, which means the price of protection against a default has gone up. Traders typically read that move as a sign that the bond market is getting more cautious, and in this case it arrived while the stock was already under pressure.

The timing adds to the concern. Bond yields have spiked over the same period, pushing up the cost of borrowing across the market. For a business that relies on debt to finance data centers and the graphics processors that fill them, higher rates and wider credit spreads hit the funding side directly.

Investors will be watching whether the trend carries into November and whether the company offers reassurance about its financing. For now, the combination of a falling stock and deteriorating credit signals has shifted the conversation from growth to confidence.
