Jev doesn't remember 2025: test across 17,036 Polymarket markets

Testing Jev on 17,036 Polymarket markets resolved before its release gave AUC 0.59–0.68 — the same as on 9,138 markets resolved after it. The model doesn't recall 2025 outcomes: it puts Trump's inauguration at 0.70 versus a market price of 0.99. Sports markets are the exception, with AUC 0.79 in 2025.

• Jev's AUC on historical markets is 0.59–0.68 vs 0.94 for market price
• Jev gives Trump's inauguration 0.70 while the market priced it at 0.99
• On 2025 sports markets Jev scores 0.79 vs 0.60–0.69 in 2026
• 17,036 markets before release and 9,138 after the 10 September 2026 launch
