This document presents a formal astrophysical wager on the origin of Jupiter-Mass Binary Objects (JuMBOs). Contrary to standard models of chaotic ejection, it proposes the "Vortex-Grip Model," suggesting these binaries form in-situ via the collapse of filamentary structures governed by coherent vorticity. Key Elements: Geometric Prediction: The rotation axes of the components are predicted to be preferentially collinear with the binary separation vector, rather than randomly oriented. Physical Basis: This alignment is posited as a "fossil signature" of the angular momentum of the progenitor vortex. Falsifiability: The wager establishes clear mathematical criteria for axial alignment. If future observational data (e.g., via spectroscopy or polarimetry) reveals a stochastic distribution of spins, the hypothesis is falsified. The challenge invites the community to use spin-orbit geometry as a definitive test for planetary-mass binary formation models.
