Predicted for 31. December 2026
·
Based on: Speculative
Bitcoin trades at ~$80,861 on September 18, 2026 (CoinGecko/CoinDesk). The $90,000 threshold requires approximately +11.3% growth over 3.5 months to year-end. Polymarket values BTC at ~83% probability of surpassing $100,000 by end of 2027; aggregated crypto prediction markets estimate ~55% for the $90k threshold by year-end 2026. Structural drivers: post-halving bull cycle (April 2024 halving → historically 12–18 months upside, currently month 17), sustained spot Bitcoin ETF inflows (BlackRock IBIT and Fidelity FBTC showing positive weekly flows), and growing institutional adoption. Counterweights: US 10Y yield above 5.01% (September 18, 2026) increases opportunity cost for risk assets; Fed rate hikes likely in October and December 2026 (Polymarket: ~55% for October).

The Nikkei 225 closed at approximately 65,102 on Friday, 18 September 2026 — well above analyst consensus (BofA: 61,000; UBS: 54,000; IG: 52,000). Polymarket priced the 55,000–60,000 band at ~44% as the most likely year-end outcome, but this data predates the index's run to 65,100 and is now stale. Polymarket currently shows only ~10.6% for the 65,000–70,000 range and ~15% cumulative above 65,000, which appears to significantly underestimate odds given the current price. The BoJ rate hike to 1.25% on 18 September strengthens the yen and creates a structural headwind for export-heavy Nikkei constituents. Surpassing 66,000 by year-end requires a modest +1.4% gain; over a 3.5-month window with ~15% annualised volatility we estimate 45% probability.

Copper traded at USD 6.62/lb on 18 September 2026 (+1.24% day-on-day). The platform's open year-end target of USD 7.00/lb implies a sustained uptrend. Key drivers: global AI infrastructure buildout, energy-transition demand (EVs, heat pumps), and tight mine supply in Chile and Peru. No Polymarket market found for 25 September specifically. The USD 6.75 threshold requires ~+2.0% — achievable in a week of positive momentum but not guaranteed.

The IBEX 35 closed at 19,384.70 points on September 18, 2026 (+0.32%). The 19,100 threshold is 1.5% below the current level. With historical IBEX daily volatility of ~0.9–1.2% and two trading days remaining until Monday September 22, the 2-day standard deviation is approximately 1.6–1.7%, placing the threshold ~0.9 standard deviations below current levels — implying ~82% probability of remaining above. Macro support: SNB expected to hold rates at 0.00% (consensus: 40/41 economists, Reuters poll); EUR/USD stable at 1.1461; no critical ECB decisions within the window. No existing Cassandra prediction explicitly covers the IBEX 35.
