If you really understand this tweet, you must have started making profits in Polymarket, haha In Polymarket (and similar prediction markets), structural mismatch and price mismatch are definitely the biggest and most stable sources of opportunities at present, especially in 2026 when the market size has exploded but the efficiency is not fully mature. Retail dominance and liquidity fragmentation make these mismatches repeatedly appear every day. Although bot/HFT is fierce, there is still a lot of visible fat in niche/low liquidity markets for humans. 1. Price mismatch: The most direct, common, and easy-to-use "free money". YES+NO total price ≠ $1 (deviation is often 0.5% -3%), buy low and sell high or buy all to lock in the price difference. High probability closing session: The event is basically fixed, with a probability of 95%+, but the price is only between 0.97-0.995. Buy, hold, and eat to determine the yield ("high probability bond"). 30 seconds after a news outbreak or a momentary deviation in a low liquidity market: rapid restocking and recovery. From 2024 to 2025, a net profit of over $40M has been squeezed out, and although it will be compressed in 2026, it will still exist, especially in the event of multiple opportunities or niche events. 2. Structural mismatch: Higher level, more durable, higher theoretical return, but also higher execution threshold. The core issue is that the logic/dependencies/rules have not been properly priced by the market, and the platform structure itself has created inefficiencies. Typical example: Logical mutual exclusion/dependence on market price conflicts, such as implicit probability mismatch between "Trump wins" and "Republican wins"; UMA oracle/source definition/dispute mechanism not understood by the public, resulting in deviation from the true resolution probability, such as the UFO/Trump fuzzy case; Polymarket vs Kalshi same event price deviation due to liquidity/user base/execution friction; Intra market biases such as Orderbook squeeze, Oracle latency, NegRisk rebalancing, etc. Why are these two categories the biggest opportunities? In 2026, Polymarket will still be in the "retail+news driven" stage, with institutional/HFT entry (Wall Street $200k+recruitment) smoothing out high frequencies, but it has not completely eliminated the inefficiency of low to medium liquidity/rule dependence. The frequency of price mismatch is the highest, with almost no risk (single market arb has exceeded $39M), and the alpha of structural mismatch is the most persistent (rules/logic will not disappear in the short term). The winning rate of pure "inaccurate prediction" information edge is difficult to exceed 60-70%, while mismatch is mechanical,+EV, and repeatable - the essence of stable earning lies in the structural inefficiency of the platform and the pricing deviation of the audience. Human beings can still play: bots monopolize the ultra short term/high frequency, but the structure+price mismatch of political niche, crypto timing, and dispute bonding remains a battlefield for skilled players. One sentence: Polymarket's real money is not betting on the right events, but eating structural inefficiencies and pricing deviations. Price misallocation provides you with stable cash flow, while structure misallocation provides you with occasional bursts (especially for those who understand the rules/can handle them). Polymarket
