Analysis

4d ago

United Russia is priced at 65¢ with a notably asymmetric risk profile—the "No" side offers a 408.5% implied yield versus just 118.5% for "Yes," suggesting significant tail risk that the ruling party fails to secure the most seats despite historical dominance. The market has declined 5¢ over seven days with 116% realized volatility, yet maintains relatively thin liquidity at $81.6K open interest and only $7.4K daily volume, making it susceptible to sharp moves as the September 2026 election approaches. With 166 days to expiration and a neutral regime score, the high information arrival rate (0.6/h) indicates active price discovery, though the 2.0 cliff risk index warrants caution on execution given the thin spreads may not reflect true depth.
