Meta Andromeda Algorithm Claim Analysis: Impact on Stock and Advertiser Sentiment

2025-11-19 08:35:30 EST

An advertiser/investor claimed Meta’s new “Andromeda” ad algorithm is broken, citing frequent outages, budget waste without results, and potential advertiser pullback. The claim also mentioned threats of lawsuits over lack of transparency and unauthorized changes, advising against investing in Meta.

Meta’s (META) stock price dropped 0.72% on the event day (2025-11-19) to $597.69, despite the Communication Services sector rising 0.97% that day [0]. This suggests a mild negative reaction to the claim, though not a significant sell-off.

Meta’s 1-month performance is -16.63%, but analysts maintain a “Buy” consensus with an average target price of $840 (40.5% above current levels) [0]. The event introduces new uncertainty, but existing analyst sentiment remains positive.

The claim contrasts with Meta’s Q3 2025 earnings call, where the company reported a 14% increase in ad quality on Facebook surfaces due to Andromeda improvements [0]. This creates a divergence between advertiser complaints and Meta’s official stance.

  Algorithm is broken, leading to budget waste and transparency issues [user input].

This development raises concerns about potential advertiser dissatisfaction and legal risks related to Meta’s Andromeda algorithm. Users should monitor:

1. Meta’s official response to the claim.
2. Further advertiser complaints or legal actions targeting Andromeda.
3. Changes in analyst sentiment or target prices.

Users should be aware that unresolved advertiser complaints about Meta’s Andromeda algorithm may impact the company’s revenue growth and stock performance. This development warrants careful monitoring of further updates from Meta and the advertising community.
