70% — the median of 6 frontier models, resolving by 2027-09-26.

Answer

Gemini (Google): 82% — A 30% drawdown from the calendar peak is an almost universal feature of Bitcoin's historical annual volatility. Historically, Bitcoin suffers at least one 30% pullback in every single bull or bear cycle year except unusually muted periods. With the 2026 peak locked in by Dec 31, 2026, any standard multi-month consolidation before April 2027 triggers the threshold. A continuous macro bull market pushing relentlessly into Q1 2027 without a leveraged wipeout is the only invalidating scenario.

Answer

Claude (Anthropic): 68% — Turns on whether Bitcoin's historically extreme volatility produces a >30% drawdown from its 2026 high within ~18 months. Bitcoin has suffered 30%+ peak-to-trough drawdowns in nearly every year since inception, making this close to the historical base rate. The window spans over a year (through Sept 2027) covering any 2026 peak, giving ample time for a correction typical of crypto cycles. A sustained institutional-driven low-volatility regime or continuous ETF inflows without a major pullback would be the main reason this fails.

Answer

GPT (OpenAI): 87% — Bitcoin’s historical volatility makes a 30% drawdown within the next year more likely than not, even after a new high. Bitcoin has repeatedly suffered 30%+ corrections during bull and post-bull phases, often within months of local peaks. No regulator or issuer must act; a risk-off shock, leverage unwind, or ETF-flow reversal can produce the threshold quickly. Odds would fall materially only if spot demand stays unusually steady and derivatives leverage remains restrained through March 2027.

Answer

Grok (xAI): 72% — Whether the 2026 high is followed by a typical 30%+ correction inside the remaining 3–6 months. BTC posted ≥30% peak-to-trough drops in most years 2013–2025; even 2024–25 bull legs saw 20–40% swings on spot. If the 2026 high prints after October the window to 31 Mar 2027 shrinks, cutting odds versus full-year history. A late-year melt-up that holds until April (2017-style) is the main miss; otherwise the base rate dominates.

Answer

DeepSeek (DeepSeek): 62% — A 30% drawdown from a 2026 peak is a routine event in Bitcoin's cycle, and the window is long enough to make it more likely than not. Bitcoin has seen a 30%+ peak-to-trough drop in every calendar year since 2011 except 2023, so the base rate over a 12-month window is roughly 80-90%. The 2026 peak is already set or near, and the post-halving cycle historically tops out in late 2025/early 2026, with the sharpest declines following within 6-12 months. The main uncertainty is whether a new all-time high is set after today, which would reset the peak and require a fresh 30% drop from that higher level before April 2027.

Answer

Qwen (Alibaba): 62% — Bitcoin has drawn down 30%+ from a local peak roughly once per year historically; the question is whether 2026's peak is already in. BTC has experienced at least one 30% drawdown in every calendar year from 2014–2025 except 2023 (~23% max drawdown), giving a base rate near 85% per year. If the 2026 peak is already set (likely if we're past the post-halving cycle top), a 30% correction is the modal outcome; if the peak hasn't arrived yet, the window… A sustained ETF-driven bid and institutional allocation could compress drawdowns below historical norms, but leverage and macro shocks have repeatedly overwhelmed that…
