Using the Sei Market Cap Calculator
Market cap is simply the live SEI price multiplied by the number of coins in circulation, and this page does that with the current price loaded for you. The supply field starts at roughly 6.73 billion SEI, which is where it stood on 5 August 2026 — supply moves, so check it against a market data source if you need an exact figure, and edit the field.
Sei's supply is bounded at 10 billion SEI, so the fully diluted valuation is a real ceiling rather than an open-ended one. The MC/FDV row shows how much of that supply is already trading: the closer it is to 100%, the less future dilution is waiting for you, and for SEI that gap is currently 67%.
The comparison field answers the question people actually come here for: what would SEI be worth at some other valuation? Enter a target market cap and the calculator returns the implied SEI price and the multiple from here. It is arithmetic, not a forecast — reaching a larger cap means absorbing every holder willing to sell on the way, and sEI is a high-beta layer 1 with a large uncirculated supply — check the unlock schedule before treating a rally as structural.
The SEI price behind each market cap

SEI's circulating supply is about 6.73B (as of 5 Aug 2026), 67% of a 10.0B total. Market cap is only price × supply, so a target valuation pins one exact price — no guesswork.
A $1 billion cap would put SEI at $0.1485, a $10 billion cap at $1.49, and a $100 billion cap at $14.85. On the fully diluted 10.0B supply those prices are lower, because 3.27B SEI is still to be issued — the FDV block above works that denominator in.
Figures are derived from SEI's own daily closes over the window shown and are bounded by it — not all-time values. Prices move; treat them as context, not a forecast.

Frequently asked questions
- What is Sei's market cap?
- Multiply the live SEI price by the circulating supply — around 6.73 billion SEI as of 5 August 2026. The calculator above loads the current price and does this for you; the result updates the moment you change either field.
- How do I calculate the SEI price at a given market cap?
- Divide the target market cap by the circulating supply. The comparison field above does it directly and also shows the multiple against today's SEI price, which is usually the more sobering number.
- What is Sei's fully diluted valuation?
- FDV prices all 10 billion SEI at the current price, including coins not yet circulating. The difference between FDV and market cap is the supply still to enter the market — worth knowing before you treat market cap as the whole picture.
- How do you calculate crypto market cap?
- Market cap = current price × circulating supply. A coin at $2 with 500 million coins in circulation has a $1 billion market cap. Note that it is circulating supply, not total supply — tokens still locked in vesting contracts or a treasury are excluded.
- What is the difference between market cap and FDV?
- Market cap uses only the coins in circulation today. Fully diluted valuation (FDV) prices every coin that will ever exist, including locked and unminted supply. A project with a $200M market cap but a $2B FDV has 90% of its supply still to hit the market.
