Highest temperature in Tokyo on August 8?

Platform comparison

Market context

Tokyo’s reading will be decided by the highest **Daily Observations** temperature at Haneda Airport, so the market is really about whether the day tops the relevant Celsius band rather than whether it simply feels hot. With the crowd currently at **0% YES**, the implied view is that the record will land below the lowest winning threshold, even though mainstream forecasts point to a notably warm August day in the low-30s Celsius. AccuWeather’s Tokyo forecast shows a high around 92–94°F, while other services place the day near 33–35°C, which is broadly consistent with a hot summer afternoon but not necessarily enough to shift a market that is pinned at zero.[1][2][3][5][9]

For framing, this sort of market behaves more like a *single-source adjudication* than a public-vote contest: the only result that matters is what is logged in the table, not the headline high. That makes it closer to a referendum with a hard count than to a jury split such as Eurovision’s 50/50 system, where interpretation can sway the outcome. Weather markets also tend to move late because the decisive number is often printed only after the day develops, so traders usually watch short-term forecast updates, hourly temperature curves, and any sign of afternoon convective cooling or showers rather than the morning headline alone.[7][8][11]

The main catalysts are the same ones that shift a temperature band in real time: cloud cover, humidity, sea breeze strength, and any thunderstorm potential later in the day. Current forecasts already show heat, but also some late-day instability, with one source flagging a 25% precipitation chance and another noting possible thunderstorms in the evening.[1][3] For a market ending at 12:00 UTC, the most important dependency is whether the observed peak at Haneda is reached before the early-afternoon local maximum; after that point, the probability should only change if the published observation source revises or records a higher peak later in the day.[7][8]

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.

Is entertainment trading worth the effort?

Niche, but lucrative for experts. Award markets have fewer informed traders than political markets; combining industry expertise (film, music) with active research often surfaces mispricings. Volume cap: large bets move the market.
