Recent statements from Google DeepMind’s new chief Koray Kavukcuoglu, indicating Gemini 4 has entered post-training with an early output targeted “as soon as possible” and well before year-end, have lifted implied probabilities for mid-October dates. Traders weigh this against Google’s pattern of flagship delays, including the unreleased Gemini 3.5 Pro originally slated for June, and a focus on iterative Flash variants through September. Competitive pressure from recent OpenAI and Anthropic updates reinforces the push for a quicker cycle, yet the absence of a firm timeline or preview keeps the “no release by October 31” outcome at the top of the market at 36 percent. Key catalysts ahead include any Antigravity platform testing results or official announcements that could shift sentiment toward specific October windows.
