Yahoo Finance released its list of four major uncertainties for 2026, including: 1. Tech giants defying the AI bubble: Despite ongoing discussions about an AI bubble and renewed investor skepticism about data infrastructure spending, tech giants have not changed course. 2. The inevitable chaos brought about by the next Federal Reserve Chairman's inauguration could cast a shadow over any future progress in inflation. 3. The prediction market boom, but also faces backlash: Not to be outdone by Robinhood, Coinbase, through a partnership with Kalshi, allows users to trade the outcomes of real-world events. The growth and popularity of prediction markets offer a novel way to measure sentiment, but also raises questions about misconduct, the probability coverage of outcomes, and the encroachment of new financial instruments into more aspects of our lives. 4. The expansion of the "Musk deal": SpaceX's IPO is noteworthy, forming a clever "reverse operation" compared to its privatization of SpaceX.
