Meta’s rapid iteration cycle on Muse Spark drives the even odds across early-to-mid October dates for version 1.4 or later. The 1.3 update arrived September 2–3 with notable gains in coding and agentic performance, following 1.2 by roughly four weeks, while CEO Mark Zuckerberg highlighted upcoming open-weight releases and teased the larger “Watermelon” model. Traders see these factors creating pressure for another incremental update before month-end, yet Meta’s flexible development timelines, focus on efficiency benchmarks, and competition with frontier systems from OpenAI, Anthropic, and Google leave no single date dominant. The 13.5% chance of no release by October 31 reflects uncertainty around exact feature thresholds and internal priorities.

A qualifying model must have a name or model identifier that includes "Muse Spark" and be designated as version 1.4 or higher, regardless of capitalization, hyphenation, spacing, or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 1.4 or higher named in the same manner as Muse Spark 1.2 or Muse Spark 1.3 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 1.4, such as Muse Spark 1.3 (released September 2, 2026, including any of its reasoning modes, open-weight re-releases, rollouts, promotions, or snapshots), 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.
