How much will the total U.S. plant-based milk market be worth in the year ending in April 2023, in millions of USD?

Data from SPINS summarised by the Plant Based Foods Association and The Good Food Institute shows U.S. retail sales of plant-based milk totalled $1.86 billion in the year ending April 2019 (Good Food Institute, 2019).

Plant-based milk alone accounts for almost half the total plant-based alternative foods market. Dollar sales of plant-based milk grew 6% in the past year and 14% over the past two years. Plant-based milk currently accounts for 13% of all dollar sales of retail milk.

How much will the total US plant-based milk market be worth in the year ending in April 2023, in millions of 2019 USD?


Resolution

This question will resolve as the value of the US market for plant-based meat, as estimated by SPINS. The market value is to be adjusted for inflation and given in 2019 prices. SPINS' estimate of the value of the US market for plant-based foods is the sum of their estimates of the value of the US market for the following subcategories of plant-based alternatives: almond milk, soy milk, coconut milk, rice milk, oat milk, and other plant-based milks and blends.

In the event that the only data available is that for the year ending in December, and if it cannot be constructed or obtained any other way (such as by using the following year's data release, or by contacting the relevant organisation), then this question shall resolve as the total value of the market for the year ending in December of the previous year.

SPINS is to be considered to be substantially different if the methodology for estimating the size of the market is substantially changed, such as when using the new methodology, estimates of the historical size of the market (currently $1.6b in 2017, $1.8b in 2018, $1.9b in 2019, with all years ending in April) changes by more than 50%.

In case SPINS data is substantially different or not available, it is left to the discretion of an admin to either resolve this question ambiguous, or consult an alternative estimate. However, this alternative estimate should only be used if it is judged that the estimate is likely the estimate follows an estimation method that is at least 90% likely produce an estimate within 50% of the estimate obtained by following the SPINS methodology, subject to updates considered reasonable in case new plant-based subcategories emerge, or previously existing subcategories that were excluded from earlier SPINS estimates constitute a larger share of the total value.

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.

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.
