2026年美國麻疹病例？

This market will resolve according to the numerical rank of how hot 2026 is when compared against all other years for which the Global Land-Ocean Temperature Index has data.

Years will be ranked in descending order, starting with the hottest as number 1, the second hottest as number 2, etc.

If 2026 ties with any other year, it will resolve according to the place the year it ties with occupies.

This market will resolve immediately once the specified data becomes available, regardless of whether the figure for the relevant years is later revised.

The primary resolution source for this market will be the figure found in the table titled "Land-Ocean Temperature Index (C)" under the column "No_Smoothing" in the row "2026" (https://data.giss.nasa.gov/gistemp/graphs/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used. If no information for 2026 is provided by NASA by March 1, 2027, 11:59 PM ET, this market will resolve based on a consensus of credible reporting.

2026年會是歷史上最熱的年份之一嗎？

This market will resolve according to the number of natural volcanic eruptions with a Volcanic Explosivity Index (VEI) of 4 or higher between January 1 and December 31, 2026, 11:59 PM ET.

The primary resolution source will be the Smithsonian Institution Global Volcanism Program (GVP: https://volcano.si.edu/), specifically the cumulative figures for 2026 for VEI 4, VEI 5, and VEI 6 released on the page currently titled "Eruptions Avg 2000-2024 (N/T)" (https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear) as of March 31, 2027, 12 PM ET. Any prior updates will not be considered finalized.

If this dataset has not been updated to include all relevant events by March 31, 2027, or if the Smithsonian GVP becomes permanently unavailable, this market may resolve based on a consensus of credible scientific sources, including the U.S. Geological Survey (USGS), national or regional volcanic observatories, or credible reporting of a scientific consensus.

Note: Smithsonian Institution Global Volcanism Program databases, which include eruptions that reached the relevant threshold prior to this market’s timeframe (e.g., https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear&checkyear=2025), will not be considered.

2026年有多少大型火山爆發（ VEI ≥ 4 ） ？

This market resolves based on the date on which Episode 53 of the ongoing Halemaʻumaʻu eruption at the summit of Kīlauea begins, according to the United States Geological Survey Hawaiian Volcano Observatory (HVO). 

"Aug 13 or later" resolves "Yes" if Episode 53 has not begun, per the HVO-stated onset date, before 12:00 AM HST August 13, 2026. If Episode 53 has still not begun by 11:59 PM HST August 31, 2026, "Aug 13 or later" resolves "Yes."

Resolution is based on the onset date and time for Episode 53 as stated by HVO in the first Observatory Message or Status Report confirming the episode has begun (e.g., "Episode 53 of the ongoing Halemaʻumaʻu eruption began at [time] on [date]"). The onset date stated in that message determines which bracket resolves "Yes," even if the message itself is published after the onset. Precursory low-level activity that HVO does not designate as the episode onset does not count. If HVO does not designate the next fountaining episode as "Episode 53," the next confirmed Halemaʻumaʻu fountaining episode after Episode 52 will be treated as Episode 53 for resolution purposes.

If HVO states a different onset time in a subsequent report, the most recently stated time governs.

The primary resolution source for this market will be HVO's Observatory Messages (https://www.usgs.gov/observatories/hvo/observatory-messages) and HVO's Kīlauea daily updates; however, a consensus of credible reporting citing HVO may also be used.

2026年人類登月？

This market will resolve to "Yes" if NOAA Coral Reef Watch's Bleaching Alert Area for the Main Hawaiian Islands virtual station reaches "Bleaching Alert Level 1" (or a higher alert level) on the Current Coral Bleaching Alert Level on any day within this market's timeframe (from market creation through December 31, 2026, 11:59 PM ET). Otherwise, this market will resolve to "No". 

The Bleaching Alert Area for the Main Hawaiian Islands virtual station reaching Bleaching Alert Level 1 (or a higher alert level) on any single day within this timeframe is sufficient for a "Yes" resolution. For the purposes of this market, Bleaching Alert Level 1 corresponds to a Degree Heating Week (DHW) value of 4 or greater °C-weeks at the Main Hawaiian Islands virtual station, as calculated by NOAA Coral Reef Watch from the 90th-percentile daily HotSpot values within that station's boundary.

The primary resolution source for this market will be the "Bleaching Alert Area" reading on NOAA Coral Reef Watch's Main Hawaiian Islands virtual station gauge page (https://coralreefwatch.noaa.gov/product/vs/gauges/hawaii.php). If that page is unavailable or has not been updated, resolution will use NOAA Coral Reef Watch's own data for the Main Hawaiian Islands virtual station in any other format it publishes (for example, its regional virtual station time-series data files, available at https://coralreefwatch.noaa.gov/product/vs/data.php), which apply the same station-level methodology. Readings for individual 5km satellite pixels that are not aggregated to the Main Hawaiian Islands virtual station will not be used.

Only NOAA Coral Reef Watch readings dated within this market's timeframe (from market creation through December 31, 2026) can trigger a "Yes" resolution. If NOAA Coral Reef Watch data covering this timeframe has not been published by January 4, 2027, this market will remain open until January 11, 2027, or until such data is published, whichever comes first. If no NOAA Coral Reef Watch data covering any day within this market's timeframe is ever published, this market will resolve to "No".

Only tornadoes appearing in the final NCEI dataset for all months of 2026 will count.

As of market creation, the December report is not yet scheduled, however the release schedule can be found here: https://www.ncei.noaa.gov/access/monitoring/dyk/monthly-releases. The market will resolve based on the first relevant tornado count published on the NCEI tornado time-series page after this scheduled release time.

If the value published after this scheduled release time is labeled preliminary, it will still determine resolution, and the market will resolve independently of any subsequent revisions, corrections, or retroactive adjustments. 

The market will not resolve based on any preliminary values published before the scheduled release time.

If no data is published by the scheduled release time, or if the NCEI website is temporarily unavailable, this market will remain open until that data is made available. If the relevant data is not made available by the date of the next scheduled publication ET, this market will resolve based on available data for the most recent prior month. If the NCEI website becomes permanently unavailable, this market will resolve using another credible source.
