Suggested face

No ticket

  1. Spot is BRTI (what settles). Coinbase vs last BRTI print is a stale-book rest, not the 15m forecast.
  2. Up needs 3¢ leftover. Down needs 6¢. Pay 40–80¢ — dogs and 91¢ favorites both lost.
  3. $3 floor · ¼ Kelly on 5¢ · 5% of cash.
  4. No adds. No side flips.
  5. Sell if model leftover is gone and ≥4¢ is locked. If the model is still ≥80%, need ≥15¢ locked — don't scratch an 80¢ payout.
  6. Last 60s: sit unless the 60s-average race is ≥8¢ vs the book.

A gap is expected value against our model, not locked arbitrage. Kalshi settles on CF Benchmarks BRTI (60-second averages), not the Coinbase vol + BRTI (or Coinbase+$5) spot on this desk. Fees and the spread are already subtracted. The blend starts as mostly Kalshi and lets our model take over as time runs down. We only flag a side when that blended leftover is at least 3¢. Asks under 40¢ are skipped — those tickets were 0-for on the live tape. Book arb would require Up ask + Down ask under $1 after fees — that almost never prints.
