April 26, 2026 - April 29, 2026, due to extreme market inefficiency, almost all options saw their Yes prices surge. For example, '≤-0.4%' skyrocketed from 9.3c to 40.35c, and '0.9–1.1%' rose from 22.1c to 40.55c, reflecting the absence of arbitrage mechanisms and the blind influx of speculative capital.
April 11, 2026 - April 13, 2026, the price of '0.0–0.2%' plunged from 23.5c to 9c before rebounding to 17c, and '0.9–1.1%' rose from 27.8c to 36c before settling at 33.1c, indicating that in an illiquid and highly inefficient market, small capital trades can trigger drastic volatility.
March 27, 2026 - March 28, 2026, the price of '1.2%+' dropped from 33.5c to 26.5c, and '0.3–0.5%' dropped from 31c to 21c, representing random volatility in a highly inefficient market.
March 11, 2026 - March 14, 2026, market prices saw a broad, mild increase (3-6 cents), such as '-0.3– -0.1%' rising from 32.5c to 38c, which primarily reflected ongoing market confusion and expanding arbitrage opportunities.
February 16, 2026, following the release of Japan's Q4 2025 GDP data, the market reaction was muted, largely maintaining a uniform distribution.
