According to Odaily, the Supreme Court may soon rule on the legality of Trump's tariffs, a decision that will have profound implications for the scope of the US president's power. Lawyers believe a ruling this week is unlikely, with most expecting it to be made in early 2026. Polymarket data shows a 76% chance of a court ruling against the Trump administration and at least overturning some of the tariffs imposed under IEEPA. However, analysts and lawyers are preparing by considering several scenarios, such as: 1. A mixed ruling: One possible path the Supreme Court might take is to rule that the "reciprocal" tariffs imposed under IEEPA are illegal, while retaining the relevant tariffs on fentanyl flows. 2. A court ruling that IEEPA tariffs are illegal: If the court rules that all or part of the IEEPA tariffs are illegal, importers will focus on refunds of already paid tariffs. 3. A court upholding the tariffs: For the market, this could mean maintaining the status quo.

According to Odaily Planet Daily, Alex Svanevik, CEO of on-chain analytics platform Nansen, stated in an article on the X platform that he still loves Ethereum because it introduced him to the cryptocurrency world, and he still holds ETH. However, he believes that the Ethereum community is now filled with a culture of complacency. Whenever Ethereum is criticized, someone will say things like "Ethereum's TVL is still very high" or "some metrics are not objective." The Ethereum community needs to be vigilant, otherwise it may face failure before 2030.
