Will Anthropic have the third best AI model at the end of April 2026?

The current Chatbot Arena leaderboard (last updated April 1, 2026) confirms Anthropic occupies 1st and 2nd places with scores of 1504 and 1499, while Google holds 3rd at 1494, and no other Anthropic model appears in the top 10, making it extremely unlikely for Anthropic to claim exactly third by April 30. Market prices show Yes at 25¢ (up slightly from 24¢), still significantly overpricing the low-probability event of an Anthropic model slipping to or entering exactly third place amid stable rankings and no new releases. With 23 days remaining, buying No at 78¢ offers high-confidence (>90% true probability) and attractive short-term returns.

The current Chatbot Arena leaderboard (as of April 1, 2026, likely unchanged) shows Anthropic firmly in 1st (1504) and 2nd (1499), with Google 3rd (1494); Anthropic's third-best model is 11th (1474), a 20-point gap unlikely to position it third by April 30 without extraordinary shifts. No evidence of recent leaderboard changes or new model releases that would enable a Yes resolution, confirming the analyst's assessment of near-zero Yes probability. Thus, No shares at 76¢ offer strong edge with true No probability >90%, actionable given the short timeframe to resolution.

Current leaderboard data (OpenLM.ai, 3 Apr 2026) shows Anthropic holds the #1 and #2 spots, while the #3 spot belongs to xAI's Grok‑4.20. No Anthropic model appears in third place, and there is no evidence of a new Anthropic model that could overtake others before 30 Apr 2026. Therefore the market’s 24% “Yes” price is overstated, making a “Buy No” trade justified.
