Kalshi Politics — Mispricing Audit (Anchor, NO-side structural)

Will the Bank of Canada hike 25 bps at its Oct 28, 2026 meeting?

YES condition: For YES to pay, the Bank of Canada must announce a 25 bp increase in the target for the overnight rate at the Oct 28, 2026 fixed announcement date, resolved by the Bank's press release (rules_primary; rules_secondary empty; closes 13:29 UTC Oct 28, one minute before the 09:45 ET release). A new action by an institution: Anchor-shaped.

Prob: 28% pre-market → 30% final. Market YES 28/32 (mid 30). CORRA OIS 31% hike / 69% hold as of Oct 5 (BlueGamma). The book tracks swaps.

Resolver profile. Kalshi resolves on the BoC decision text; the 12 stored precedents (Jun, Jul, Sep 2026 ladders) all resolved cleanly on the announced target rate with no definitional dispute. Resolver-risk deduction: 0 pts.

Vehicle and calendar (primary sources). Oct 28 09:45 ET is on the Bank's published schedule and is an MPR meeting (bankofcanada.ca upcoming events). Before it: Labour Force Survey Oct 9, September CPI and the Business Outlook Survey on Oct 19 (Statistics Canada schedule; BoC calendar). No further BoC speeches are scheduled before the decision. Summary of deliberations for Oct 28 publishes Nov 10.

Evidence for hold (NO). Sep 2 press release: core measures "close to 2% in July", ex-gasoline 2.2%. Sep 16 deliberations contain no mention of raising the rate; the trigger is written as "if higher energy prices did spill over into other components of the CPI … it could require a monetary policy response". Aug CPI (Sep 14): trim 1.9%, median 2.0%, common 2.6%, ex-gas 2.4%, headline 3.0%. Aug LFS (Sep 4): employment −42k, unemployment 6.4%, wages +2.0% y/y, the slowest since 2017. Q3 Business Outlook Survey: near-term inflation expectations eased to 3%, 2–5 year at 2.5%. RBC and TD call hold through 2026; Watt (Sep 22) argues the raw CORRA-futures odds overstate the hike by ~15 pts.

Evidence for hike (YES). Macklem, Halifax, Sep 21: "nor do we want to be too slow to respond if inflationary pressures are becoming more persistent"; "if oil prices stay near $100 … we would expect inflation to edge up". Deliberations: "the longer they were high, the more likely they would be passed through". Brent $101–102 on Oct 5 with Hormuz disruption ongoing. Q2 GDP +3.3% annualized, above the July MPR. Fed hiked Sep 16. UBS, Manulife, Oxford Economics and Scotiabank moved to an October hike call (Oct 1–2); UBS expects Sep CPI 3.3%.

Entry context (after the probability was committed). Candles: YES 7¢ on Sep 2 → 22¢ Sep 11 → 42¢ Sep 16 (Fed) → 46/47 Sep 24 → 38 Sep 30 → 30/32 Oct 2–5. 48h move: −3¢, not a chase. Book: NO buyer pays 72¢ against 65 resting YES bids at 28¢, then 68 at 25¢ (depth cap would be 21 contracts). vol24h 1,525; OI 33,698.

Cleanest loss. Oil stays ~$100, the Sep CPI on Oct 19 shows ex-gasoline and core drifting higher, and Governing Council acts on its own spillover language at the MPR meeting. That is the current pass-through continuing, not a new discrete event: a continuation tail, exactly as the stored 26SEP-H0 lesson warns.

Verdict: REJECT — inside spread (fair NO 69–70¢ vs 72¢ ask, zero edge after fees) and continuation tail. Conviction would have been LOW. Re-examine only after Oct 19 if core/ex-gasoline prints flat and the leg still trades above 25¢ YES; even then the OIS anchor must be beaten by more than fees.

Precedents consulted: KXCBDECISIONCANADA-26JUL-H25 ("two-sided guidance keeps both middle rungs alive in the narrative while neither gets priced"), 26JUN-H25 ("explicit two-sided risk language is empirically a hold tell"), 26SEP-H25 ("price the hike leg off the core/ex-gasoline prints released the week before the meeting, not off the gasoline-driven headline"), 26SEP-H0 ("trend-driven tail makes NO-on-hike a continuation-tail reject under Anchor even when the fade looks attractive").
