Meta Platforms shares fell in after-hours trading on Wednesday following an earnings report that disappointed investors and provided a weak revenue outlook.

The decline reflects growing investor anxiety over the high cost of developing artificial intelligence. As Meta pours capital into AI agents, the resulting pressure on profit margins has sparked a sell-off among shareholders.

Share prices dropped between 10% [2] and 11% [3] in after-hours trading on the NASDAQ. Some reports described the decline as almost 10% [1].

"Meta tumbled after market after its earnings disappointed investors as well as its outlook," James Gruber said.

The company provided a revenue outlook for the third quarter ranging from $61 billion to $64 billion, with a mid-point of $62.5 billion [3]. This forecast failed to meet the expectations of the market.

Investors are particularly concerned with the rise in costs associated with AI agents [2]. While Meta continues to integrate these technologies across its platforms, the immediate financial impact is squeezing profit expectations [1].

The volatility comes as the company balances the need for aggressive technological expansion against the demand for consistent quarterly growth. The market reaction suggests a lower tolerance for high spending that does not yield immediate, scalable revenue gains [1].

The market reaction indicates a shift in investor sentiment toward 'AI fatigue,' where the mere promise of artificial intelligence is no longer enough to sustain a high valuation. Investors are now demanding clear evidence that massive capital expenditures on AI infrastructure and agents will translate into proportional revenue growth, rather than simply increasing operating costs.
