April 8, 2026 - April 9, 2026, the >1.29ºC option bounced from 1.0c to 16.85c, while the 1.25–1.29ºC option retreated from 95.8c to around 78.25c. The reason is that traders began hedging the tail risk of an unexpectedly high official data release as the deadline approached. April 5, 2026 - April 8, 2026, the price of the 1.25–1.29ºC option surged from 38.55c to 94.9c, while the >1.29ºC option plummeted from 53.75c to 1.7c. The reason is that as the official NASA GISTEMP release date approaches, the final convergence of climate proxy data has almost entirely confirmed the anomaly will fall into the 1.25-1.29ºC bracket, eliminating residual uncertainty. April 6, 2026 - April 7, 2026, the price of the 1.25–1.29ºC option surged from 20.75c to 79.6c, while the >1.29ºC option plummeted from 74.75c to 11.95c. The reason is that early April releases of preliminary temperature data from authoritative climate agencies confirmed the anomaly will likely land in the 1.25-1.29ºC bracket, shattering previous expectations of a >1.29 anomaly. April 4, 2026 - April 6, 2026, the price of the >1.29ºC option surged from 49.65c to 74.75c, while the 1.25–1.29ºC option plummeted from 42.85c to 20.75c. The reason is that as March ended, more authoritative complete monthly climate observation proxy data was published, showing exceptionally high anomalies, prompting sharp market repricing. April 1, 2026 - April 3, 2026, the price of the >1.29ºC option surged from 9.5c to 32.1c before retracing to 22.45c, while the 1.25–1.29ºC option dropped from 68.0c to 52.4c. The reason is that preliminary climate proxy data following the end of March indicated exceptionally high anomalies, raising expectations that the final figure might exceed 1.29ºC. March 31, 2026 - April 1, 2026, the price of the 1.25–1.29ºC option surged from 50.3c to 68.0c, while the 1.20–1.24ºC option plunged from 34.5c to 19.5c, as complete end-of-month climate proxy data confirmed the anomaly is highly likely to exceed 1.25ºC. March 17, 2026 - March 23, 2026, the price of the 1.15–1.19ºC option crashed from 35.5c to 12.5c, while the 1.25–1.29ºC option surged from 15.4c to 30c, due to mid-March real-time climate monitoring data showing global daily temperatures did not cool as expected. March 10, 2026 - March 16, 2026, the price of the 1.10–1.14ºC option crashed continuously from 25c to 12c, as the market realized the La Niña cooling effect was delayed, rotating capital into higher temperature brackets.
