Show HN: Did prediction markets do any predicting this midterms?
I've heard so much about how prediction markets are the guiding light in this dark world. But when put head to head against polls or Nate Silver's FLIPR model, they are really a wash. Especially looking at flipped or close-by-polls races, there is no alpha compared to a traditional poll-based model. Was this obvious to everyone else too? Can we treat them like the entertainment they are and tax them for the terrible ads?

版本与成本证据
来源票数: 29 votes (2026年11月7日 UTC; cumulative since publication)；前次同口径记录为 1（2026年11月7日 UTC），两个观测值不等于需求增长。 可供比较的近期同类记录：“[推广] 做了个在线 AI 母带处理：免费试用，不用注册，不用绑卡” (V2EX, 2026年11月7日)；“Show HN: I built a free trivia hosting app with no accounts or subscriptions” (Show HN, 2026年11月7日)。主题相近仅用于导航，未核验其是否属于同一需求或独立证据。
适用与受影响对象
先明确变化影响的现有工作流，再判断是否升级。发布热度不证明效果提升；接口、价格或可用性变化也可能增加迁移工作。
缺失的比较信息
待补齐：新旧行为、受影响套餐与地区、生效时间、兼容性、回退路径及同一工作量下的成本。
采用与迁移验证
保存发布或政策原文，对新旧方案运行同一个任务并比较结果与完整账单；若涉及停服，先核验截止时间再安排迁移。
