4% — the median of 6 frontier models, resolving by 2076-09-22.

Answer

Gemini (Google): 4% — Detection requires an active, powerful technosignature coincidentally aligned with Earth across vast astronomical distances. Over sixty years of radio and optical SETI surveys across billions of stars have returned zero confirmed technosignatures. Major scientific bodies like the IAU require reproducible, narrowband signal verification, which vast light delays impede. Rapidly expanding observational capacity from the SKA and ELT provides only a narrow chance of finding rare active emitters.

Answer

Claude (Anthropic): 3% — Decades of SETI/technosignature searches have found nothing confirmed; no near-term breakthrough mechanism exists. No candidate signal has survived scrutiny in 60+ years of SETI; base rate of confirmed detection per decade is effectively zero. Verification requires independent replication and consensus from bodies like IAU/SETI institutes, a high bar that filters out false positives like WOW signal or Oumuamua… Expanding surveys (SKA, Breakthrough Listen, biosignature spectroscopy) raise sensitivity but detection of intelligence specifically remains a separate, much harder…

Answer

GPT (OpenAI): 18% — It turns on whether a detectable civilization is both nearby enough and transmitting in a searchable way. SETI has run for decades without a confirmed signal; sparse targets and unknown transmitter prevalence keep the base rate low. By 2076, expanded radio arrays, optical surveys and exoplanet catalogs greatly increase coverage, but major bodies require repeatable confirmation. A verified narrowband or structured signal independently recovered by facilities such as the SKA or Breakthrough Listen would sharply raise the odds.

Answer

Grok (xAI): 7% — Unambiguous technosignature must be detected and certified by NASA/IAU-level bodies by 2049. SETI/radio-optical surveys have run 60+ years with zero verified hits; even Breakthrough Listen samples <<1% of the Milky Way’s plausible emitters. Extraordinary-evidence bar plus historical false positives (Wow!, FRBs) mean any candidate needs years of independent confirmation, eating most of the remaining 24-year… A nearby industrial-pollution spectrum or Dyson-swarm IR excess would shift odds sharply; nothing like that is in current catalogs.

Answer

DeepSeek (DeepSeek): 4% — This turns on whether a real signal exists within reach of current surveys, not on our listening effort. SETI has scanned only a tiny fraction of the search space since 1960, and 66 years of null results set a low base rate. Detection needs a deliberate, persistent beacon aimed at us, since leakage signals fade below noise within a few light-years. Breakthrough Listen and FAST are expanding coverage, but no verified candidate has survived re-observation since the 1977 Wow! signal.

Answer

Qwen (Alibaba): 1% — Fifty years is long enough that a single anomalous detection could resolve this, but no credible signal has ever survived scrutiny. SETI's 60+ year track record shows zero confirmed detections despite exponentially growing survey volume; base rate is essentially zero per decade. Resolution requires consensus from major scientific bodies, meaning even a plausible candidate must survive years of replication and peer review. A confirmed signal would likely need to be repeating and detectable by multiple independent observatories, a bar no candidate has ever cleared.
