30-Day Supply Growth
30-day supply growth is the percentage increase in a token's circulating supply over the trailing month. It is a realised measurement rather than a projection: it counts supply that has already reached circulation, whichever channel delivered it, which makes it the most direct way to rank which tokens are diluting fastest right now.
TradFi parallel: Like comparing this quarter's actual share count against last quarter's, instead of the dilution implied by an unexercised option pool.
Key Takeaways
- 0130-day supply growth measures the realised percentage increase in circulating supply over the trailing month, not a projection from a vesting schedule
- 02It is channel agnostic: cliff unlocks, linear vesting, block rewards, staking emissions and airdrop distributions all register in the same figure
- 03Tokenomist's Top Supply Growth Last 30D table on the Overview ranks tokens by this metric and shows Supply Change %, Release MCap Change % and Price Change % over the same window
- 04Pairing supply growth with price change over an identical period separates dilution the market absorbed from dilution it did not
- 05Because it is percentage based, tokens with small circulating supply dominate the ranking on relatively modest absolute releases
- 06It is backward looking, so a one-off cliff can top the table and then go quiet, while a steady heavy emitter is outranked by cliff spikes even when it dilutes more over time
How It Works
Most supply metrics look forward. A release schedule tells you what every channel is authorised to add; an emission projection tells you what ongoing issuance should add. 30-day supply growth looks backward and answers a narrower question with far less modelling in it: how much did circulating supply actually grow over the past month. Because it measures the outcome rather than the schedule, it is agnostic about how the supply arrived. Cliff unlocks, linear vesting, block rewards, staking emissions and airdrop distributions all land in the same number, which is precisely what makes it useful as a ranking.
On Tokenomist the metric drives the Top Supply Growth Last 30D table on the Overview: tokens with the largest circulating supply increase over the past 30 days. The table pairs three columns over the identical window. Supply Change % is how much circulating supply grew. Release MCap Change % is the change in market cap attributable to the newly released tokens. Price Change % is the token's price movement over the same period. The pairing is the design intent, since supply growth on its own tells you dilution occurred but not whether the market absorbed it.
Read together, the columns separate absorbed dilution from unabsorbed dilution. In its 8 to 14 December 2025 digest, Tokenomist reported that WCT, USUAL, RIVER, PUFFER and STBL led 30-day supply expansion with increases of 20% to 66% over the month, and that price performance across the basket was broadly negative, which it read as supply growth driven primarily by vesting-related emissions rather than organic demand. The digest for 1 to 7 December showed the same shape with a near-identical basket, describing the moves as unlock-led dilution rather than demand growth. When a token appears at the top of the supply table with a deeply negative price column, the market is not absorbing the new supply.
The limitations follow from the same properties that make it clean. It is backward looking, so it tells you dilution happened and not that it will continue. A token that has just cleared a one-off cliff can top the table and then go quiet for a year, while a steady, heavy emitter gets outranked by cliff spikes even when its cumulative dilution is larger. It is percentage based, so tokens with small circulating supply dominate the ranking on modest absolute releases. And it is channel agnostic by construction: a 30% increase from an insider cliff and a 30% increase from block reward issuance rank identically, despite implying very different forward supply. Use it to find where dilution has actually landed, then check the release mechanism and the forward emission view before drawing a conclusion.
Real World Examples
December 2025: supply up, price down
View →Tokenomist's 8 to 14 December 2025 digest reported WCT, USUAL, RIVER, PUFFER and STBL leading 30-day supply expansion with increases of 20% to 66% over the month. Price performance across the basket was broadly negative, which the digest attributed to supply growth driven primarily by vesting-related emissions rather than organic demand.
The same names, a week earlier
View →The 1 to 7 December 2025 digest showed WCT, OMNI, USUAL, RIVER and STBL leading 30-day supply growth with 20% to 65% increases, described as largely driven by vesting rollouts rather than organic activity, with price performance across the names deeply negative. Persistence at the top of the table over consecutive weeks marks a sustained release programme rather than a single event.
Why the price column belongs next to the supply column
View →A token can grow circulating supply substantially and hold its price if demand is expanding at the same rate. The Overview table puts Supply Change %, Release MCap Change % and Price Change % over the identical 30-day window for exactly this reason. Supply growth alone establishes that dilution occurred, and only the price column indicates whether it was absorbed.
The small float distortion
A percentage metric rewards a small denominator. A token adding a few million dollars of supply against a thin float can outrank a large-cap adding far more in absolute terms. This is not a defect, since proportional dilution is what holders experience, but it means the ranking should be read alongside the release market cap change rather than on its own.
Realised growth against a forward projection
A token whose entire supply comes from block rewards has no unlock calendar to project from, yet it registers in 30-day supply growth the same way a cliff unlock does. The reverse also holds: a large projected unlock that goes unclaimed under a discretionary structure never shows up here at all. Realised and projected views answer different questions and should be checked against each other.
Frequently Asked Questions
How is 30-day supply growth different from an emission projection?
Direction and certainty. An emission projection is forward looking and derived from a schedule, so it depends on assumptions about what will be released and claimed. 30-day supply growth is backward looking and measured, counting supply that has already reached circulation. The projection tells you what is authorised to happen; the trailing figure tells you what did happen, including releases no schedule anticipated.
Why does Tokenomist show price change next to supply change?
Because dilution is only half the question. The Top Supply Growth Last 30D table places Supply Change %, Release MCap Change % and Price Change % over the same 30-day window so the two can be read together. Heavy supply growth with a flat or rising price suggests demand kept pace. Heavy supply growth with a deeply negative price, the pattern in the December 2025 digests, points to unlock-led dilution rather than growth.
Does a high 30-day supply growth figure mean more dilution is coming?
Not on its own. The metric describes the month that just ended and carries no forward information. A one-off cliff produces a high reading followed by a quiet year, while a token with steady heavy emissions is often outranked by those spikes even though it dilutes more across the year. To assess what comes next, pair the trailing figure with the forward emission view and with the release mechanism behind the growth.
Why do small tokens dominate the ranking?
Because the metric is a percentage of circulating supply, and a small denominator magnifies a modest release. A mid-cap adding 30% to a thin float will outrank a large-cap that released far more in dollar terms. Proportional dilution is what holders actually experience, so the framing is correct, but the Release MCap Change % column is the one to check when you want the absolute scale of the release.
