Factual Economics and markets

MNX lets people sell futures representing AI company stocks, bet on AI company revenues, and trade on targets such as the Epoch Capabilities Index.

Unresolvable The public record could not settle it.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

What would count as true or false

The claim has three parts. As of 2026-10-19, MNX must let users (a) sell or trade futures representing AI company stocks, (b) bet on AI company revenues, and (c) trade on other targets such as Epoch Capabilities Index thresholds. True if MNX's site, documentation or launch announcement shows all three. Mostly true if all three are present but a minor detail differs, for example the instruments are called contracts rather than futures. Mixed if roughly half the features hold, for example two of the three. Mostly false if only one feature is present. False if MNX offers none of them, or did not exist or operate as described at that date.

Reasoning

The evidence shows MNX offering valuation futures on AI companies [E1][E3] and a market on AI company revenue [E4], but no evidence item addresses Epoch Capabilities Index markets either way. Without the third feature, the evidence cannot settle whether the claim meets the criteria for mostly true (all three features) or mixed (two of three).
