Which company has the best AI model end of October?

What this question means

Anthropic at 74%, OpenAI at 17%, SpaceXAI at 8%, Google at 7%, Meta at 1%, and the rest of a twenty-one name field at zero.

The interesting comparison is the same question one month earlier on this board, which sits at 87% for the leader. Same field, same measure, a month further out — and thirteen points less confidence.

That decay is the horizon effect, and it is one of the most reliable patterns in forecasting. The further away a deadline, the more opportunity there is for the current state to change, so probability leaks away from the front-runner toward everyone else. Here the gap widens specifically toward SpaceXAI and Google, which is the crowd saying the field has more room to shift over a longer window.

Watching the same question at two horizons is the cleanest way to see how much of any forecast is simply a function of time remaining.
