OpenAI’s GPT-5.5 Pro is now available on Venice, pushing “GPT-5.5 released by April 30” to 100% YES.
The April 23 market also hit 100% YES, up from 93% just a day ago. Odds had climbed steadily over the last week, suggesting traders expected the announcement.
The April 30 market now sits at 100% YES with $30,936 in actual USDC traded daily. All relevant resolution dates are pegged at full YES confidence, with no meaningful spread across the term structure.
Combined face value across these markets is $241,174, with $233,954 in actual USDC traded over the last 24 hours. The order book is thick enough that moving prices even marginally would require substantial capital.
The release resolves the immediate market question, but it also gives a data point on OpenAI’s deployment speed for new models. A YES share at 100¢ offers no upside now. Trader attention will likely shift to markets around subsequent releases like GPT-6.
Watch for OpenAI announcements about GPT-5.5 Pro’s capabilities or limitations as Venice completes integration. Any disclosed model upgrades or security issues could affect related markets.
