According to @StockMKTNewz, the combined market capitalization of the world’s top 10 stocks rose to $26.6 trillion from $26.12 trillion week over week, a roughly $0.48 trillion increase of about 1.8% (source: @StockMKTNewz on X, Dec 27, 2025). This week-over-week increase implies aggregate price gains among the top-10 mega-cap equities over the period, based on the reported totals (source: @StockMKTNewz). Crypto traders often monitor mega-cap equity momentum because BTC has shown periods of positive correlation with major US tech-heavy indices in 2023–2024, supporting cross-asset risk sentiment tracking (source: Coin Metrics correlation analyses, 2023–2024). Key watch: if the top-10 market cap trend continues higher, traders can track BTC and ETH for potential beta-to-equities moves using the $26.6T figure as a risk-on reference level (source: @StockMKTNewz; source: Coin Metrics).
