Crunchbase's weekly tally shows that U.S. startup investors pulled back from the billion-dollar checks of the previous week, with the largest financing landing at $550 million for an AI infrastructure company. That deal led a group of rounds that all fell in the hundreds of millions.

Space tech and investment management companies also made the list of the top 10 funding rounds, signaling that capital continues to flow into capital-intensive sectors. The single source offers no point of comparison, but the data points to sustained interest in AI-related infrastructure despite a quieter week overall.
