Exploring EVE Online's Global PLEX Market For September 2025

CCP Games published EVE Online's monthly economic report for September last Tuesday. I'm still trying to figure out how to approach the data since CSM member and EVE economics YouTuber The Oz informed me that ISK is still considered active until an account has not logged in for 90 days. I do wish CCP would confirm that someplace on the internet, but until proven otherwise I'll go with the guy who has direct access to the developers. With that piece of news reviewing the active ISK delta every month wasn't really productive. So what do I write about now?

I can still note what the developers consider important.

Destruction remains relatively stable over the last ~9 months. While production continues its long term (~18 months) trend upward.

Money supply has stopped falling. However ISK velocity continues its downward trend over the last ~6 months.

MPI continues to fall.

Since I'm interested in the money supply I decided to look a little deeper into the data. According to one of the graphs in the MER, the amount of ISK actually fell in September by 1 trillion ISK, or basically remained flat. But digging into the money supply file I found two things of note. The first is that the entry for 31 August 2025 was missing. Yikes!

But even when taking that into account the file showed 2410.3 trillion ISK in the money supply, or 1.3% more than in the graphic above. And the Active ISK Delta also doesn't explain the discrepancy. But according to the data, the money supply began an upward trajectory on 9 September.

Looking at Jester's average concurrent user graph the timing for the upturn makes sense. At least the money supply is still responsive to near-time player behavior changes.

The Global PLEX Market since its inception

I know people expect information from the MER, but I'm going to post one of my own. The seven-day moving average for the price of PLEX declined by 0.7% over the course of September.

I want to dig deeper into the relationship of the PLEX market and the overall New Eden economy. I'm going to begin looking at two metrics. The first is the sale of PLEX on the GPM versus the amount of ISK entering the economy due to the game's ISK faucets.

ISK made vs ISK bought

One interesting fact to note about the data. Sales of PLEX are not included in any of the totals. Realistically the exchange of ISK for PLEX is probably considered a currency exchange effect, not an actual sale of an item.

The other statistic I want to see is what percentage of total ISK spent in the game was purchased, especially since ISK spent on PLEX doesn't count in the data.

Percentage of sales purchased with cash

For the two full months the Global PLEX Market has operated each month has exceeded 20%. I will need to set up my spreadsheet for some additional statistics but I'm still playing around trying to determine anything valuable to spend the time to track.

I am bringing back one previous chart, the quarterly Active ISK Delta going back to the start of the Alpha & Omega period.

For the quarter following the Legion expansion the amount of ISK removed from the game due to the net effect of players entering and leaving the game, including GM actions, equaled 9.0% of the starting total of 2504.3 trillion ISK. As mentioned previously in this post the MER provided two different figures for the amount of ISK in the money supply at the end of September so I cannot give a further breakdown. But for what I can give, I'd say that the Legion expansion was better received than last summer's Equinox expansion. I'll let null sec residents let me know if they felt that way.
