What will be the lowest tabulated cost of a teraflop of computing speed in 2018?

A new compendium of costs for a given amount of computational power has been created in Wikipedia, with the most recent entry as of question launch of $60/TFLOPS (this neglect a $30 entry that is given in single-precision.)

What will be the lowest cost/TFLOPS listed in this table for 2018?

Question resolves using the lowest amount listed for a date in 2018, upon the first listing of a date in 2019. If no 2018 entry is listed by 1/1/2020 or the first 2019 listing (whichever comes first), resolves ambiguous. The table entry in question should pertain to 32-bit floating point operations.

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. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.

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.

Community Stats

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.
