A funding arbitrage position buys the spot asset and shorts the perpetual on the same venue, so price moves cancel out and the funding payment becomes the return. Taker fees on both legs cost about 0.32% of notional round trip, so the current rate needs roughly 6.1 days to pay that back. If the rate does not hold that long, the trade loses money even while the funding prints positive. The 24 hour median across venues is 28.0% annualized and the best venue is now at 19.2%, so today's level is at or below its own recent average.
Over the last 24 hours the best annualized rate on SPCXX ranged from -80.5% to 87.0%, with a median of 28.0% across 312 samples. That range matters more than the spot number: a rate that spikes for one hour and collapses the next does not pay for the round trip.

Rates come straight from each exchange's public API and are re-read every hour. Annualized figures multiply the per-period rate by the number of periods in a year, which is 8,760 for an hourly venue and 1,095 for an eight-hour one. Volume is 24 hour quote volume, so it reflects dollar turnover you can actually trade against. Contracts with less than $1M of turnover are excluded from the ranking because their rates are usually noise.
