# Will Robin Hanson win a bet that the GPT line of language models will generate < $1Bn in customer revenue by 2025? Per this tweet, Robin Hanson has bet Alex Tabarrok that Systems in GPT line will by 2025 make <$1B in customer revenue clearly tied to such systems.

Will Hanson win the bet?

Resolution is positive if Tabarrok publicly concedes the bet, negative if Hanson publicly concedes the bet, and ambiguous if nobody has conceded by end of 2025.

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
