Gemini 3.5 released by May 31?

Prediction markets put the probability at 13%: Gemini 3.5 released by May 31. Currently, markets see this as unlikely (13% YES). Apple releases iOS 26.5 beta 4 for iPhone.

What’s Happening

The prediction market for a "Gemini 3.5 released by May 31" currently shows a 13% probability of a launch occurring within that timeframe, against an 87% probability that it will not. This low confidence comes despite Google’s recent aggressive expansion of its Gemini ecosystem. On April 27, 2026, the Pentagon confirmed it had added Google’s latest commercial model, Gemini 3.1 Pro, to its GenAI.mil platform, which has already surpassed 1 million users. Additionally, Google introduced the Gemini Enterprise Agent Platform on April 23, signaling a major push into agentic AI workflows. However, these developments focus on the 3.1 iteration, not the speculated 3.5, suggesting that Google may be prioritizing enterprise deployment and integration over a rapid version jump.

The market’s skepticism is further reinforced by the lack of any official Google announcement or credible leak regarding a Gemini 3.5 release. Instead, Google’s public roadmap appears centered on deepening existing partnerships. On April 22, 2026, Google confirmed that its Gemini models will power a new, more personalized version of Siri for Apple, set to launch later in 2026. This integration, alongside the Pentagon’s deployment of Gemini 3.1 Pro, indicates that Google’s immediate focus is on scaling its current flagship model through high-profile collaborations rather than rushing a 3.5 release. Meanwhile, a separate securities fraud class action lawsuit was filed on April 26 against Gemini Space Station, Inc. (ticker: GEMI), a completely unrelated entity, which may cause minor confusion in search results but has no bearing on Google’s AI timeline. [MacRumors, Apr 22] [PR Newswire, Apr 26]

Looking ahead, the key date for the market is May 31, 2026, the deadline for a potential Gemini 3.5 release. With less than five weeks remaining, the 13% probability reflects the absence of any pre-release signals, such as developer previews or beta access, which typically precede a major Google AI launch. The upcoming release of iOS 26.5 in May—which notably lacks any Gemini-powered AI features—further suggests that Apple’s integration with Google’s models is not imminent at the OS level. If Google intends to unveil Gemini 3.5, it would likely need to announce a developer event or release a technical paper within the next two weeks to build momentum. Without such catalysts, the market’s current 87% NO probability appears grounded in the observable pace of Google’s product cycle. [9to5Mac, Apr 27]
