Prediction market on Gemini 4 releasing before October 20 resolves YES
The author created a market on XO asking whether Gemini 4.0 would release before October 20, and it resolved YES after Google opened Gemini 4 Argon to the public and developers on October 13.

Resolved. Two days ago I turned my daily Gemini usage into a real market on @xomarket Gemini 4.0 released before October 20, 2026? Google officially made Gemini 4 Argon available to the public and developers on October 13. Market resolved YES. I won. Hurray 🤑 This is exactly why I keep coming back to XO. No waiting for someone else to list the market. You see something happening in real time → you create it → the crowd prices it → and it resolves cleanly. Most people just tweeted opinions. A few of us put actual skin in the game. LFXO. Join OX beta : http://beta.xo.market/?r=eclock24
