Executive summary

2 picks, 12 logged rejects, $254.54 deployed (10.2%), $2,245.46 cash (89.8%). The 45-day Tier-1 slate is almost entirely untradeable this week: of 37 Tier-1 markets inside the horizon, every one failed the mechanical cuts — dead books (vol24h 0), tail prices (ask ≤ 5¢), or both. The only near-live Tier-1 book (KXGOVTFULLFUND Sept rung, 56/62) trades 205 contracts a day on a 6¢ spread and is logged as a liquidity-floor reject. The deployable slate was five Tier-2 markets in three series. Both picks are precedent-fed, in the 60–84¢ core band, MEDIUM conviction, one leg per cluster: a telegraphed BoJ September hike at 75¢ and the NO side of an Anthropic IPO-confirmation-before-Oct-1 at ≤79¢. The Trump-Bedminster exact-trip-count cluster — the week's most tempting board — is rejected in full: the playable side sits below the 40¢ band floor, the priced side contradicts the primary-source schedule record, and the thesis is a pace-of-count bet correlated with the live KXLAGODAYS pick. A ~90%-cash week is the correct output of an efficient board, not a failure to find edge.

Thesis. The BoJ raises the policy rate 25bp to 1.25% on Sep 17–18. This is a telegraphed institutional move, not a data drift: Reuters (Aug 14, three sources) reported the Board is eyeing a September hike and considering a faster-than-twice-a-year pace — "an early rate hike has come into sight"; the July Summary of Opinions (Aug 10) flagged upside price risks and a possible faster pace; the July 31 statement warned core inflation could exceed the 2% target; and the yen stayed weak despite July's rare joint Japan–US intervention.

Precedent: KXCBDECISIONJAPAN-26JUN15-H25 resolved YES (7–1) with swaps at only ~72.6% — the store's lesson: "BoJ hold legs must be priced off the signalling, not off the bank's no-show history." KXCBDECISIONJAPAN-26JUL30-HOLD (verified this run, API-verbatim) settled YES with hawkish guidance that set up September. Counter-precedent weighed: KXFEDDECISION-26JUL-H25 — a hawkish repricing into the Fed faded to a 9–3 hold. The distinction: the Fed repricing was market-inferred from oil and CPI; this BoJ repricing is leak-driven — the institution itself speaking through its standard channel.
Resolver profile & deductions. Resolver: Kalshi on the BoJ's official policy-rate announcement; primary rate only. Cancel/delay clause → HOLD resolves YES (−1pt). Emergency inter-meeting hike does not count for this rung (rules_secondary; negligible at this horizon). No ambiguity in "Hike 25bps" for an exact-action rung. Total deductions ≈ 1pt → final 79%.

Book & entry. Entry context: yes 74/75, 3,621 contracts offered at 75¢, vol24h 3,251, OI 21,061. 14-day tape: 38¢ (Aug 4) → 87¢ intraday (Aug 14, leak day, 5.8k vol) → consolidated 74–76 by Aug 17 — entering on consolidation, not chasing the spike (48h move is −8¢, downward). Depth cap 1/3 × 3,621 = 1,207 ≫ 233; slippage ≤ 1¢. EV ≈ +4¢/contract pre-fee (+2.7¢ after ~1.3¢ fee).

Thesis. "Confirms an IPO" is mechanically defined (rules_secondary): SEC declares the S-1 effective, OR the offering is priced, OR an exchange assigns a ticker. Anthropic's S-1 is still a confidential draft (submitted Jun 1); IPO-watch reporting has the public flip in ~September, the institutional roadshow through September–early October, and first trade targeting October on Nasdaq. In the SpaceX precedent all three triggers fired within ~48 hours of first trade — a September roadshow alone resolves nothing. The fastest bull path (public flip by ~Sep 5, the 15-day JOBS Act clock, a one-week roadshow, pricing by Sep 30) is physically possible but requires beating the company's own reported target; mega-IPOs slip later, not earlier, and Anthropic has said timing depends on market conditions.

Precedent: KXIPOANTHROPIC-DATE-26JUL01 resolved NO — the resolver ruled the confidential draft S-1 announcement was none of the three triggers, and YES got cheaper on the "Anthropic files for IPO" headline (the store's inverse-headline case). KXIPOANTHROPIC-DATE-26JUN01 resolved NO on the same strict mechanics. KXIPO-26-SPACEX confirms the trigger cluster lands at pricing/effectiveness, not at roadshow launch (Jun 4 roadshow was not a trigger; Jun 11–12 was).
Resolver profile & deductions. Rules are crisp and twice-enforced strictly. Residual risk: an early Nasdaq ticker assignment being read as a trigger days before pricing (−2pt), plus acceleration risk in the hottest IPO on the board (blend −1pt toward a churning book that touched 31–32¢ Aug 11–14). Final NO = 82%. Specialist-dense book (vol24h ~4.5k) noted — the edge claimed is specific (trigger mechanics + timeline), not sentiment.

Book & entry. Entry context: yes 24/25 (NO ask 76), vol24h 4,522, OI 110,396. NO-side depth is thin at the touch: ~109 contracts within 76–78¢, 304 within 79¢ → limit 79¢ (exactly 3¢ max slippage), depth cap 1/3 × 304 = 101 contracts. 14-day tape: YES 15¢ → 31–32¢ (Aug 11–14, heavy vol) → faded to 24¢; buying NO into a fading YES, not chasing. EV ≈ +3.7¢/contract pre-fee at ~78.3¢ avg fill.
