What it means for prediction markets

• The quoted prices show a substantial cross-venue difference for the same named team and championship outcome, but do not explain its cause.
• Without contract terms and executable quotes, the snapshot does not establish whether the two positions were directly comparable or whether the gap could be traded.
• The 5:12 AM ET reading is a timestamped observation, not evidence that the same prices remained available at publication or afterward.
