U.S. economy is gathering steam. This is the chief reason why.

The U.S. economy is showing renewed momentum, and the AI boom is a central driver. Anthropic's preparations to go public signal that investor appetite for artificial-intelligence companies remains strong, while businesses are stepping up purchases of durable goods — a sign that corporate spending on equipment and infrastructure is holding up. Together, these developments point to demand that extends beyond a single sector.

For markets, the key question is durability. A sustained AI investment cycle can support earnings across technology and industrial supply chains, but it also raises questions about how much of that spending is already reflected in valuations. Durable-goods orders are worth watching as a gauge of whether business confidence is translating into real capital outlays rather than one-off purchases.

The broader takeaway is that growth is being powered by investment rather than consumption alone. That matters for how investors assess inflation, interest-rate expectations, and sector leadership in the months ahead.
