Polymarket minimum deposit
Last updated · how we verify
$3 on low-fee networks (Polygon PoS, Base, Arbitrum, Solana), or $10 over Ethereum mainnet. Polymarket charges no deposit fee. Add a dollar or two of POL for gas and roughly $5 is enough to start trading properly.
Minimum by network
| Network | Minimum | Why |
|---|---|---|
| Polygon PoS | $3 | Native settlement chain; gas is negligible |
| Base | $3 | Low-fee L2 |
| Arbitrum | $3 | Low-fee L2 |
| Solana | $3 | Low-fee chain |
| Ethereum mainnet | $10 | Gas makes smaller transfers uneconomic |

The practical advice is simple: do not fund over Ethereum mainnet unless that is where your money already is. The higher minimum exists because Ethereum gas can exceed the value of a small transfer.
What you actually need
- $3 deposit on a low-fee network.
- A dollar or two of POL for gas — Polygon transactions cost fractions of a cent, so this is a one-off that lasts.
- No deposit fee and no withdrawal fee from Polymarket.
So around $5 gets you genuinely started. That is low enough that your first trade can be small enough not to matter, which is the right way to learn a new venue.

Questions
What is the minimum deposit on Polymarket?
$3 on low-fee networks (Polygon PoS, Base, Arbitrum, Solana) and $10 over Ethereum mainnet, where gas makes small transfers uneconomic.
Is there a deposit fee?
No. Polymarket charges no deposit fee. Network gas and any third-party on-ramp fee still apply.
What is the minimum trade size?
Small — you buy shares priced in cents, so a position can be a couple of dollars. The practical floor is set by what makes sense given the spread, not by a platform rule.
How much do I need in total to start?
Realistically about $6: $3 to deposit plus a dollar or two of POL for gas. Polygon gas is fractions of a cent, so that buffer lasts a long time.
