**Recent AI model launches and heavy capital expenditure concerns have driven volatile sentiment around Meta's stock for the week of October 12.** On October 12–13, Meta released its Muse Wonder and Wonder Full frontier large language models, with CEO Mark Zuckerberg stating the company had caught up to rivals in advanced AI capabilities; this fueled a mid-week rally that pushed shares above $760. However, analyst forecasts of 2026 capex reaching $130–145 billion (with some estimates higher) and questions about monetization returns triggered pullbacks, with the stock closing near $737 on October 14–15 amid broader market caution. Strong but decelerating advertising revenue growth and upcoming Q3 earnings on October 21 remain key swing factors for traders assessing whether the week-end close clears specific thresholds.
