GPT-5 release odds and market reaction

I'm looking at the probability of a GPT-5 announcement or a substantial beta release by year-end. Given the current pace of development and the competitive landscape, I'd put the odds around 60% for some form of significant reveal, perhaps an early access program. This could have a ripple effect on related AI plays, pushing some of the more speculative names even higher, though established players like $MSFT might see less dramatic immediate impact. The real move comes when concrete commercial applications are demonstrated.
