## Questions

**Is SIREN funding-rate arbitrage profitable right now?**

Not at the full size. At $10,000 per side for 7 days the best SIREN pair (Bitget / BingX) would net +$13.56 after taker fees, order-book slippage and carry, but the slippage at that size is over the budget, so it is on watch rather than actionable.

**Which exchange has the highest SIREN funding rate?**

Bybit at +822.1% a year (0.3754% every 4 h); the lowest is Bitget at −222.1%. A positive rate is paid by longs to shorts, a negative one by shorts to longs.
