The assessment is based on strong, consistent, and direct evidence from high-authority primary sources. The provided information confirms that at least two major, representative crypto-linked US stocks experienced price increases during pre-market trading on October 29. Specifically, Yahoo Finance data shows that MicroStrategy (MSTR) had a pre-market price increase of 0.65%, and Marathon Digital Holdings (MARA) had a pre-market increase of 0.58%. These are not minor companies; they are significant bellwethers for the crypto-mining and crypto-holding equity sector. The fact that multiple high-authority sources corroborate this upward trend for key players lends significant weight to the statement.Furthermore, there is a complete absence of contradictory evidence among the relevant sources. No source indicates that any crypto-linked stock decreased in price. While the provided summaries do not contain an exhaustive list to mathematically verify a 'majority' across the entire sector, the consistent positive performance of the most prominent stocks makes it highly probable that the trend applied to more than 50% of the group. The existence of sources like CNN's pre-market page and Moomoo's 'US Market Movers' list for that day suggests a broader market trend was observable, and the specific data points we have align with the statement's claim.
