Released: I will consider a release to be a formal unveiling of capabilities. Rumors/leaks don't count. It will need to meet the following conditions

Stock price: If Llama 3 is released during the trading day, I will use the closing price of the previous full day of trading.

Month: I'll resolve this at the end of the trading day one calendar month after the model is released, or after the final trading day after a calendar month.

I will compare Meta's starting stock price with the closing stock price. If the stock price is higher, this market resolves as yes. If the stock price is lower, this market resolves as no.
