Trader consensus on Polymarket gives Anthropic a 77.5% implied probability of holding the #1 spot on the LMArena Text Arena leaderboard (style control on) by April 30, driven by Claude Opus 4.6's sustained dominance in crowdsourced benchmarks for reasoning, coding, and creative tasks since its February release. A March 27 data leak exposed "Claude Mythos," an unreleased model Anthropic describes as a "step change" in capabilities—excelling in agentic workflows and cybersecurity simulations—bolstering expectations it will extend the lead before resolution. xAI's Grok-4.20 beta (7%) and Google's Gemini 3.1 Pro (6.5%) trail closely but lack confirmed April upgrades to overtake, while OpenAI's recent GPT-5.4 variants (3%) have underperformed in arena Elo ratings. Watch for beta rollouts or leaderboard shifts in the next month.
