1 megaton meteor strike in 2026?
1 markets · 5mo
AI overview· Updated 2d ago
The market prices a 1% chance of a 1‑megaton meteor strike in 2026, in line with the historical frequency of such impacts, and the near‑certainty reflects the absence of any known asteroid on a collision course.
📊 Base rate: The Earth is struck by a meteor of at least 1 megaton of TNT energy roughly once every 100 years, giving an annual baseline probability of about 1%.
What's driving it
- • No recent headlines are provided; the 99% No odds solely reflect the statistical rarity of a 1‑megaton event and the lack of any detected asteroid on a collision trajectory for 2026.
- • The market has been stable at 99% No, indicating that traders see no new evidence or survey data that would raise the probability above the long‑term average.
The bullish case
- • A previously undetected 20‑to‑30‑meter asteroid could be discovered late in 2026 with an impact trajectory, leading to a sudden shift in probability.
- • The historical record shows that large impacts do occur, and the 1% baseline means a strike is not impossible; a single observation could turn the odds.
- • Current surveys miss a fraction of near‑Earth objects, especially those approaching from the sunward direction, so a surprise impact remains a non‑zero risk.
The bearish case
- • The vast majority of large near‑Earth objects have been cataloged, and none are projected to impact Earth in 2026.
- • The 1% historical probability is already priced in, and without a new detection the odds are unlikely to deviate from the background rate.
- • Impact events of this size are rare enough that the expected number per century is roughly one, making a specific year unlikely by default.
What to watch
- • No specific upcoming events are cited in the provided headlines; ongoing asteroid surveys (e.g., Pan‑STARRS, Catalina Sky Survey) continuously update the threat catalog, but any new discovery of a 20‑meter‑plus object with a 2026 impact date would strongly move the market toward Yes.
- • If a new near‑Earth object is announced by the Minor Planet Center with a potential impact in 2026, the odds would spike sharply toward Yes until the trajectory is refined.
- • The end‑of‑year summary of asteroid discoveries by NASA or ESA in December 2026 could confirm no threat, reinforcing the No outcome.
