Anthropic’s established release pattern drives strong trader consensus that the next Sonnet model will appear promptly on arena.ai’s Text Arena leaderboard. Sonnet 5 launched June 30, 2026, and entered Text, Agent, Vision, Document, and Code Front-end arenas within days, landing at #32 overall in Text while showing gains in agentic and coding tasks over Sonnet 4.6. Earlier versions, including Sonnet 4.6 in February, followed the same rapid evaluation path, reflecting Anthropic’s emphasis on third-party benchmarking alongside official API and claude.ai availability. No new Sonnet has been announced since Opus 5 in July, leaving the timeline for a follow-on release uncertain, though historical cadence suggests a potential update within the next 3–6 months. Competitive pressure from OpenAI and Google models on the same leaderboards continues to incentivize quick public testing, supporting high implied probability for an immediate Text Arena debut once the next model ships.

This market will resolve to "Yes" if the next Anthropic Sonnet model added to the Arena.AI Leaderboard (https://arena.ai/leaderboard/text/overall-no-style-control) has at least the specified score at 12:00 PM ET on the calendar date following the date on which it first appears on the leaderboard. Otherwise, this market will resolve to "No".
Claude Sonnet refers to a model by Anthropic explicitly named Sonnet. Qualifying models include Claude Sonnet 5.1, Claude Sonnet 5.5, Sonnet 6, or any other Sonnet variants. Models under any other name, such as Opus, Haiku, Fable, or Mythos, will not qualify, unless the model is explicitly and officially named Sonnet by Anthropic.
Results from the "Score" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off will be used to resolve this market. This market will resolve solely based on the specified score in the Score column of the leaderboard, regardless of any underlying granular or unrounded data presented elsewhere.
A model marked "AutoEval" will not be considered added to the leaderboard. Only scores displayed without the "AutoEval" label will be considered.
If multiple models are added to the leaderboard on the same calendar date (ET), the highest-scoring model will be used for resolution. Models added to the leaderboard on the calendar date following the initial qualifying model's first appearance will not be considered. If a model is first added to the Arena.AI Leaderboard but is subsequently removed and not re-added, such that it is not displayed on the leaderboard at 12:00 PM ET on the calendar date following its first appearance, its appearance will not qualify as added to the Arena.AI Leaderboard.
A qualifying model must be newly added to the Arena.AI Leaderboard. Whether the model was previously released, publicly accessible, in beta, or otherwise available before appearing on the leaderboard is irrelevant for this market.
The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://arena.ai/leaderboard/text/overall-no-style-control. If this resolution source is unavailable at 12:00 PM ET on the calendar date following the date on which the qualifying model first appears on the leaderboard, this market will resolve based on the first subsequent instance at which such a score becomes available on the leaderboard. If it remains unavailable through the end of the seventh day after the qualifying model first appears on the leaderboard or if no qualifying model release occurs by December 31, 2026, 11:59 PM ET, this market will resolve to "No".Anthropic’s established release pattern drives strong trader consensus that the next Sonnet model will appear promptly on arena.ai’s Text Arena leaderboard.
