CryptoQuant analyst Darkfost stated that the cost basis of short-term holders (STH) of Bitcoin has confirmed a crossover above the cost basis of active long-term holders (LTH), indicating a shift in market momentum. Based on this, he judges that the Bitcoin bull market has been confirmed. This is the 5th occurrence of this signal in history, but he emphasized that there is still a possibility of misjudgment regarding the relevant indicators."Active LTH" is defined as long-term held supply that has moved at least once in the past 7 years, to exclude long-term dormant or illiquid BTC. Currently, over 3.5 million BTC that have been held for more than 10 years remain dormant, with this portion of supply increasing by an average of about 8,000 to 30,000 BTC per month. Since 2019, this indicator has only shown negative growth once, due to an early miner reactivating and transferring about 100,000 BTC, which is considered a relatively isolated event. Darkfost believes that this signal currently reflects positive changes in the Bitcoin market, with ETF liquidity inflows being one of the driving factors.

According to a 46-page report from financial investment data company PitchBook, the market platform Kalshi has a baseline scenario valuation of approximately $30.4 billion, a peak valuation of about $42.1 billion during strong market performance, and a pessimistic scenario of $22.8 billion. Kalshi completed a $1 billion Series F financing in May this year, with a post-money valuation of $22 billion.PitchBook expects Kalshi's revenue to reach $6.4 billion by 2030, with adjusted profits reaching $3.7 billion, and believes that partnerships with platforms and market makers such as Robinhood and Susquehanna will help consolidate market share. The report lists the regulatory risks of the sports prediction market as a key variable affecting valuation, with data showing that the sports market currently contributes about 69.9% of Kalshi's event fee revenue; if Exotics products such as multi-event combinations are included, the proportion rises to 82.4%.Several states in the U.S. and Native American tribes are suing over the legality of Kalshi's sports prediction products, and related cases have created discrepancies between federal appellate courts, with the Supreme Court expected to intervene next year. PitchBook believes that even if the final ruling is unfavorable to Kalshi, the company may still adjust its business model through state-level licensing and the development of non-sports prediction products, but a significant decline in sports revenue will still notably impact its growth expectations.
