In December 2025, Tencent was reported to be using Datasection's data centers near Osaka and in Sydney to access thousands of Nvidia's latest GPUs under multi‑year contracts, despite U.S. export limits on high‑end chips to China. Datasection's initial batch of 15,000 Blackwell processors and planned deployment of tens of thousands of B300 chips underpin deals exceeding $1.2 billion, while the company faces investor scrutiny, short‑seller criticism, and regulatory sensitivity around its links to Chinese clients and Singapore‑based First Plus Financial Holdings. The firm says its GPU projects are fully compliant with applicable laws and rely on approvals from Nvidia and the U.S. Commerce Department.

On December 21 2025, Ethereum co-founder Vitalik Buterin used Farcaster posts to argue that prediction markets help counter extreme opinions and misinformation on emotionally sensitive topics. He responded to criticism of platforms like Polymarket, claiming that small markets on major events do not create harmful incentives and can offer more accurate risk signals than social media or headlines. While Buterin firmly opposed assassination markets, he suggested social norms, oracle design, and journalistic standards as ways to make such markets unworkable.

After reaching the $120,000-$125,000 range in October 2025 and then dropping to the mid-$80,000s, Bitcoin is trading around $87,700 as traders eye profit-taking into January. Historical monthly data show January has often delivered positive returns for BTC, with notable gains in 2020, 2023 and 2025, even though some past years posted steep losses. The analysis suggests that if BTC enters January below its 2025 high and under the $90,000 mark, the greater risk could be exiting too late rather than too early.
