Meta released Muse Spark 1.3 on September 2, 2026, delivering the primary catalyst for current trader sentiment through gains in agentic workflows, long-horizon coding, and tool efficiency—roughly 20% fewer tool calls and 25% fewer tokens versus 1.2—while maintaining the same pricing. The update rolled out immediately via Muse Code and the Meta Model API, with a max-reasoning mode pending final safety checks, positioning it competitively against frontier models from Anthropic, OpenAI, and Google amid their own recent announcements. This rapid iteration—following 1.1 in July and 1.2 in August—reflects Meta Superintelligence Labs’ aggressive cadence under Alexandr Wang, supporting broader goals like personal agents. Upcoming catalysts include the max-reasoning variant and any open-weights plans, though the just-shipped release has likely shifted implied probabilities sharply toward earlier resolution windows.

A qualifying model must have a name or model identifier that includes "Muse Spark" and be designated as version 1.3 or higher, regardless of capitalization, hyphenation, spacing, or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 1.3 or higher named in the same manner as Muse Spark 1.1 or Muse Spark 1.2 would qualify, including a new whole-number generation such as Muse Spark 2, while models whose name does not include "Muse Spark" or which retain a version designation below 1.3, such as Muse Spark 1.2 (including any open-weight re-release of it), Muse Glimmer, or Muse Image, will not qualify.
A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must either be clearly defined and publicly announced by Meta as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.
The primary resolution source for this market will be official information from Meta, with additional verification from a consensus of credible reporting.
