Roblox shares have declined 70% after second quarter results showed monetisation was 2% below company guidance, which impacted overall bookings. The share decline followed lower-than-expected average bookings per daily active user among the under-13 group, due to a focus on long-term retention over short-term monetisation. "This underlying mix shift was compounded by changes in our recommendation algorithm, which optimises for long-term retention and is, therefore, providing more impressions for highly retentive games at the expense of near-term monetisation. Roblox forecasts third quarter bookings between $1.58 billion and $1.65 billion, representing a year-over-year decline of 14% to 18%. Investments in AI, content diversification, long-term retention and safety, though creating near-term friction, position us to maximise our share of the global gaming market."
