Meta's free cash flow has gone negative for the first time, a meaningful line crossed for a company investors have long trusted to generate cash even while spending heavily. The AI buildout has reached a scale where outflows now outpace what the business brings in.

At the center of that spending is Muse, the platform Mark Zuckerberg is backing with billions in the belief that it can become the next major computing platform. The ambition is sweeping, but the market is demanding early proof that the investment has a credible path to returns.

Shares have fallen 8% since the earnings report, a slide that reflects investor unease. When a company known for its cash generation flips to negative free cash flow, the burden of proof on future spending shifts considerably higher.

The number to watch from here is when and how Meta signals a return to positive free cash flow, because that is the clearest way Zuckerberg can demonstrate that Muse spending is a bridge to growth.
