NO on Will OpenAI release GPT-6 before Sep 1, 2026?

OpenAI shipped GPT-5.6 on Jul 9, 2026 and as of mid-July there is no GPT-6 announcement, model card, or date; tracker consensus puts GPT-6 in Q4-2026/2027. Resolver: Kalshi release determination, public release required (gov-restricted previews did not resolve the GPT-5.6 market early); priced risks: -2 pts surprise generational launch under competitive pressure from Anthropic's Claude 5 sweep, -1 pt naming ambiguity ('GPT-6 or greater'). Cleanest tail risk: OpenAI announces GPT-6 at a surprise August event and takes it GA within ~2 weeks, as it did preview-to-GA with 5.6.
