Which company's model will be ranked #1 on the Arena (formerly LMArena) text leaderboard at the end of October 2026?

Resolution source: https://arena.ai/leaderboard/text (formerly lmarena.ai/leaderboard/text), default view as served to a logged-out visitor, with no filters or categories changed.

How it resolves: I check the leaderboard as soon as possible after 2026-10-31 23:59 UTC. The answer is the company that developed the model listed in first position (highest Score). If the page shows a tie on the top Score between models from different companies, the market resolves to those companies in equal shares. If a live check isn't possible, I'll use the first Wayback Machine snapshot of that URL after the deadline.

Answers:

• Google: any Google / Google DeepMind model (Gemini etc.)

• Anthropic: any Claude model

• OpenAI: any GPT / o-series / OpenAI model

• xAI: any Grok model

• Other: anything else (Meta, DeepSeek, Alibaba, Mistral, Moonshot, Zhipu, etc.)

State at creation (Oct 2, 2026 board): #1 is gemini-4-argon-high (Google) at 1525 ±9 on ~4.9k votes. The next five are all Anthropic models at 1501–1505 (claude-opus-4-6-high, claude-fable-5-high, claude-opus-5.5-high). The best OpenAI model is gpt-5.6-sol-xhigh at #20 (1484), and GPT-6 isn't listed yet. The best xAI model is #36.

Leaderboard methodology changes made by Arena during the month don't affect resolution: whatever the default view shows at the deadline is what counts.
