Context
The contract’s implied probability has shifted over its lifespan, with trades placing it. The price path suggests a market that has rarely entertained the possibility of a test, with only modest fluctuations. The market resolves to “Yes” if Russia intentionally detonates a device that produces a nuclear chain reaction—fission or fusion—in a non-combat context by Jan 1, 2027 (ET). Accidents, radiological dispersal devices such as dirty bombs, and actions by third parties do not count. A test need not be officially claimed by Russia; evidence that satisfies a broad consensus of credible reporting will suffice, much as the 1979 Vela Incident was ultimately attributed to a specific state. If no such event is documented by the cutoff, the market resolves to “No.”
The contract’s resolution date, set at Jan 1, 2027, is the only hard deadline. The market settles based on whether credible reporting can confirm an intentional Russian nuclear test by then. No other scheduled milestones are specified in the rules.
FAQ
What defines a nuclear test in this market?
The intentional non-combat detonation of a device producing a nuclear chain reaction (fission or fusion), regardless of yield.
Does Russia need to claim the test for a Yes resolution?
Not necessarily. If a credible consensus of reporting attributes a nuclear detonation to Russia, the market can resolve Yes.
What does not count as a nuclear test?
Accidents, dirty bombs (radiological dispersal devices), and actions by third parties are explicitly excluded.
When does the market resolve?
After the cutoff date of December 31, 2026 (ET), or earlier if a qualifying event is confirmed.
