Total compute TOP500 supercomputers Nov 2026
In the seven decades since the invention of the point-contact transistor at Bell Labs, relentless progress in the development of semiconductor devices — Moore’s law — has been achieved despite regular warnings from industry observers about impending limits.
The TOP500 project collects and ranks system performance metrics of the most powerful non-distributed computer systems in the world. The project was started in 1993 and publishes an updated list of the supercomputers twice a year. The first of these updates always coincides with the International Supercomputing Conference in June, and the second is presented at the ACM/IEEE Supercomputing Conference in November.
The TOP500 ranks high-performance computing (HPC) by recording how fast a computer system solves a dense n by n system of linear equations in double precision (64 bits) arithmetic on distributed-memory computers (TOP500, 2019). This is an implementation of the High Performance Computing Linpack Benchmark.
What will the the sum of the level of performance (in exaFLOPS) of the all 500 supercomputers in the TOP500 be according to their November 2026 list?
This question resolves as the sum of performance (at Rmax) in exaFLOPS (1 exaFLOP = FLOPS) of all supercomputers listed on the November 2026 TOP500 list.

This question resolves ambiguously if TOP500 stops reporting performance in terms of Rmax measured in TFlop/s on the Linpack benchmark.
Metaculus help: Predicting
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.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.
Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
