EVE Online's December 2025 Monthly Economic Report: A Look At PLEX And The Money Supply

Yesterday CCP Games published EVE Online's monthly economic report (MER) for December 2025. While some of the information in the graphics is incorrect, I tend to just utilize the file with the money supply information.

First, what did the developers consider economically important in December?

• A ~23% increase in Production value over December.
• Drop in High Sec Asteroid Mining value, and increase in High Sec Ice Value.
• Bounty Prizes ISK faucet has stabilized over December, while the Commodities ISK faucet has seen a ~20% growth.
• MPI continues to fall.

Next, we need to know how the population in New Eden fluctuated. For that I turn to Jester's average concurrent user charts.

The final graph for 2025

The general trend in December was a decrease to a bit below an average of 27,000 accounts logged in at any time last month. For the year the average increased around 3000 accounts logged in from January to December, something in the neighborhood of a 10% increase.

The ACU for each year from 2007 to 2025

Over the course of the year, the number of ships increased for the third year in a row. While only a year-over-year increase of 1%, the number has increased by 26.3% since 2022's low total of 18,187.

When referring to logged in accounts, the Active ISK Delta is usually useful, at least on a quarterly scale. And in an economy with a money supply of 2.5 quadrillion ISK, I find percentages work better for understanding the metrics.

Quarterly AID from 2018 to 2025

The Active ISK Delta is the net effect of ISK coming and going with player accounts, including all GM actions. Most of the time the number is negative as the game tends to bleed experienced players faster than new players can earn ISK. December is one of five quarters since the beginning of 2018 to experience a positive ISK amount entering the game. In fact, the last quarter, led by the Catalyst expansion, Crimson Harvest and Winter Nexus events, set a record with the money supply increasing by 2.5%. During the entire quarter the money supply increased by 7.3%.

For the entire year, the starting amount of the money supply declined by 12.3% due to player movement in and out of the game. Except for 2023, that amount has decreased by 24.2% per year since 2017. 

Okay, so the number of logged in accounts is up, although perhaps not as much as in the past two years. Also, the amount of ISK leaving the game is going down. The next question is, does a relationship exist between the new global PLEX market and the number of accounts logged in?

The global PLEX market in 2025

In December, the effect of the sales resulted in a huge amount of PLEX exchanged. For the months, the daily average price of PLEX increased from 4.7 million ISK to 4.8 million ISK. Christmas Eve also saw the greatest volume of PLEX sold in the short history of the PLEX market at 3.8 million sold.

Now, while the price of PLEX remained fairly steady in December, overall the price has declined. From the creation of the global PLEX market in July to the end of 2025 the average daily price of PLEX declined by 20%. Making PLEXing accounts that much easier is expected to increase the number of accounts involved in multi-boxing, at least somewhat.

The monthly economic reports contain a lot more data but I'm mostly interested in the money supply and PLEX. I have a few more ideas on what to extract out of the MER but I think I'll work on those for the new year.
