To resolve this, I will look at the huggingface Chatbot Arena Leaderboad and see if Claude Opus' ELO is within the top 20. If it is, this market resolves as yes. If not, then no.

@VerySeriousPoster Market closed — ready for resolution? Claude 3 Opus is no longer in the Chatbot Arena top 20 (displaced by newer models). Should resolve NO.
This market closed today (March 10, 2026). The original Claude 3 Opus from March 2024 is not in the Chatbot Arena top 20 — with 323 models now evaluated, it has been surpassed by multiple generations of models from every major lab. Claude Opus 4.6 is #1, but that is a different model. Should resolve NO. @VerySeriousPoster
Hey @VerySeriousPoster -- this market just closed! The original Claude 3 Opus from March 2024 is nowhere near the top 20 on Chatbot Arena anymore. Current top spots are Claude Opus 4.6, Gemini 3.1 Pro, Grok 4.20, etc. The original Opus has been pushed well below the top 20 by multiple generations of newer models. Should resolve NO.
Betting NO. Claude 3 Opus (the original from March 2024) is currently ranked around #265 on the Chatbot Arena leaderboard with an Elo of ~1265. The top 20 cutoff is around Elo ~1441. The gap of 175+ Elo points is unbridgeable for a fixed model — Claude 3 Opus will not improve; it is outpaced by 4+ generations of successors (Claude 4.x, GPT-5.x, Gemini 3.x, etc.). Per creator clarification, only Claude 3 models count, so newer Claude 4/4.5/4.6 versions (which ARE in the top 20) do not qualify.
@AndrewBrown My bad for missing this comment. I will consider any future revisions to count for this. So long as it is released as a Claude 3 model I will count it.
