Polymarket Holds Anthropic at 84.5% as Meta’s Instagram AI Tool Stirs Privacy Row

Traders on the on-chain prediction platform Polymarket continue to back Anthropic as the developer of the best artificial intelligence model by the end of July, with the contract pricing the outcome at 84.5% even as Meta’s rollout of a new Instagram image tool intensifies competition among the major AI labs, according to blockchain.news.

The market, titled “Which company has best AI model end of July?”, has attracted $4,972,688 in traded volume, per data cited by the outlet. Google sits a distant second at 12.55%, OpenAI trails at 4.2%, while xAI and Meta are both priced near zero at 0.15%. The market resolves on 31 July 2026.

Meta’s Instagram launch reshapes the competitive backdrop

The pricing shift comes as Meta introduced its first AI image model from Meta Superintelligence Labs on Tuesday, branded Muse Image and embedded directly into Instagram. The company has pitched the launch as a direct challenge to OpenAI’s GPT Images 2.0 and Google’s Nano Banana 2, according to blockchain.news.

The tool lets users generate “remixes” of photos and, under an automatic opt-in for public accounts, incorporate other users’ public-profile likenesses by tagging a username in a prompt. Meta’s own help materials state that users will not be notified when content is generated using their likeness, and that images already created will not be deleted even if a user later switches settings. Opting out is possible only by making an account private or adjusting the newly introduced privacy toggles.

Despite the launch representing a significant consumer-facing move for Meta, the Polymarket contract has not shifted meaningfully in its favour, with the outcome still priced at just 0.15%. Anthropic’s leading price has in fact softened slightly, down 2.5 percentage points over both the past 24 hours and the past seven days, though it remains comfortably ahead of every rival.

On-chain markets as a live gauge of institutional AI sentiment

The persistence of Anthropic’s lead illustrates how Polymarket’s blockchain-settled contracts are increasingly used to track sentiment around corporate technology races, not just political or macroeconomic events. The platform’s structure, with each outcome priced as an independent yes/no rung, allows traders to express conviction across multiple competitors simultaneously without needing a single binary bet.

blockchain.news also reports elevated volume on adjacent contracts tied to product timelines, including a market on the release date of “GPT-5.6”, where 31 July is priced at 98.65% on $3,405,593 in volume, and a narrower contract on a 9 July release date priced at 78.55% on $684,668. Such clustering suggests traders are treating Polymarket as a running scoreboard for the pace and credibility of AI product releases across the sector.

For institutional observers, the episode underscores a broader pattern: decentralised prediction markets are absorbing capital and attention around corporate technology announcements in near real time, offering a market-based signal that sits alongside traditional analyst commentary. Whether the gap between Anthropic and Google narrows as the 31 July resolution date approaches, and whether Meta’s consumer AI push eventually feeds through into the pricing, will be watched closely by traders positioned across the contract.
