Lighter fees & measured trading cost
Lighter currently sets the floor: nothing we measure fills a $100K BTC futures order cheaper than its $4.96 all-in. FeeFloor measures Lighter's futures market on BTC, ETH and SOL — fee, spread and slippage, not just the headline rate. That's a live fact, not an endorsement; the breakdown below shows where the cost sits and how it shifts with size. We count only what a market order pays to execute — funding, withdrawals and gas are measured separately.

What our measurements show
Lighter's rank moves with trade size: #1 of 49 at $10K, but #9 at $10M. Fees are flat — depth is not.
Only 0.00 bps of the 0.50 bps total at $100K is the advertised fee — the rest is spread and slippage the fee page never mentions.
At $10M, slippage alone reaches 7.86 bps — size this venue accordingly.
Cost by trade size
Fees are flat, but spread and slippage scale with size — so a venue that wins at $10K can be mid-pack at $10M. BTC futures, taker.

Lighter: quick answers
What does a $100K BTC trade actually cost on Lighter?
As of 2 August 2026, a $100K BTC futures market order on Lighter costs $4.96 all-in (0.50 bps): 0.00 bps fee, 0.27 bps spread and 0.23 bps slippage. That ranks #1 of 49 venues we measure.
Is Lighter better for small or large orders?
Right now, small orders: Lighter ranks #1 at $10K and #9 at $10M. Fees are flat percentages, but slippage grows with size, so the answer shifts with the venue's live order-book depth.
Does Lighter have hidden costs beyond the trading fee?
Yes — every order-book venue does. On top of the 0.00 bps list fee you pay the live spread (0.27 bps right now) and slippage that grows with order size (0.23 bps at $100K). Neither appears on the fee page, which is exactly why we measure them.
