Round 1
One saved weekly assessment of Enceladus's ocean supports indigenous reproducing cellular life., kept as it was published. It is an estimate from three models reading the evidence, not proof the hypothesis holds, and it did not set any price.

The hash commits to this round's recorded bytes. It does not prove the wording is sound or that the science is right.
openai/gpt-6.1-sol
Ocean-derived phosphates and freshly ejected organic compounds support habitability, not indigenous cellular life. No retrieved result demonstrates cell-bounded metabolism and serial reproduction, independently reproduced with contamination controls; neither do observations establish ocean-wide incompatibility with life. I interpret the probability as support for living ocean inhabitants, not merely habitability; uncertainty about life's emergence dominates the estimate.
What would change this view: Independent, contamination-controlled observations of ocean-derived cells repeatedly metabolizing and reproducing would sharply raise my estimate and support YES.
anthropic/claude-sonnet-5.5
I found no detection of cells, metabolism or reproduction in Enceladus plume material. No mission has returned a sample, and Cassini flew before any life-detection payload. The YES test is far from met. The NO test needs proof that the whole ocean is uninhabitable, and nothing shows that. So the probability is near zero and the verdict is UNDECIDED, not NO.
What would change this view: A peer-reviewed, independently reproduced detection of replicating, metabolizing cells in traceably ocean-derived samples would raise it. Strong evidence that the entire ocean is uninhabitable would move the verdict to NO.
x-ai/grok-4.7
Cassini and later analyses establish a subsurface ocean, plume, and complex organics, but no peer-reviewed, independently reproduced observation of cell-bounded metabolism and serial reproduction from traceably ocean-derived samples. Habitability models do not show conditions incompatible with cellular life throughout the ocean, including refugia, so neither terminal YES nor NO is met.
What would change this view: Independent labs reproducing cell-bounded metabolism and serial reproduction from traceable ocean samples with contamination controls would move this to YES.
Round 1: score 0.20
OpenAI estimated 0.40. Ocean-derived phosphates and freshly ejected organic compounds support habitability, not indigenous cellular life. No retrieved result demonstrates cell-bounded metabolism and serial reproduction, independently… Anthropic estimated 0.01. I found no detection of cells, metabolism or reproduction in Enceladus plume material. No mission has returned a sample, and Cassini flew before any life-detection payload. The YES test is far from met. The NO test… xAI estimated 0.18. Cassini and later analyses establish a subsurface ocean, plume, and complex organics, but no peer-reviewed, independently reproduced observation of cell-bounded metabolism and serial reproduction from traceably… The panel disagreed by 0.39, so read this average as soft. The three models did not return a unanimous confident binary, so the market is not decided.
No audit bundle is recorded for this round. A bundle from another round is not substituted for it.
