We think the persistent services line and the energy pass-through into core will surprise to the upside. ## Overview The Consumer Price Index for May is the next major inflation read. Kalshi's market for the headline year-over-year figure currently puts a 14¢ price on the contract that pays if CPI prints above 4.3% — implying the market thinks there's about an 86% chance the print comes in at or below 4.3%. We see a higher probability of an upside surprise than that. Services CPI, which makes up roughly 60% of the index, has been printing at a sticky 5%+ annualized rate for three months running. Energy prices have ticked up in the last six weeks, and the BLS methodology will pass some of that through into both the energy line and several core sub-indices. A 4.3% headline is a real possibility, not a tail. This basket has two positions, both on the Yes side. Bet Yes on the 'CPI YoY above 4.3%' contract at 14¢ — the main bet, chosen because it's the cheapest expression of the upside-surprise view available on Kalshi right now. If the print delivers, the position pays out at $1.00 — roughly a 7x return on capital. Bet Yes on the annual 'gas prices hit $5 by Dec 31' contract at 30¢ — a second leg that expresses the same inflation-upside view through energy. Model edge here is negligible (market 30%, model 29.3%), but the leg pays a 3.3x return if pump prices spike, and a basket about energy pass-through belongs on the same side as the inflation tail it's modelling. ## Backtest - Since inception (2026-04-28): +6.4% - Live leg coverage: 2 / 2 - Daily candles: 44 _Backtest is hypothetical, computed against the Octagon research report's entry prices.

The setup is a single dated catalyst Unlike most macro themes, this one has a hard release date. The BLS publishes the May CPI report at 8:30am ET on the announced release day, and the Kalshi contract settles within minutes of that release based on the official headline figure. There is no ambiguity about when the basket pays out or what triggers it. ### 2. Why we lean toward an upside surprise Services CPI, the largest single component of the index, has been printing at a sticky 5%+ annualized rate for three months. Shelter, transportation services, and medical care all have momentum. Energy is no longer subtracting from the headline. None of these inputs argues for the year-over-year figure dropping enough to put the print comfortably below 4.3%. ### 3. Why the asymmetric payoff is the whole point At a 14¢ entry, this contract pays out roughly 7-to-1 if our view is right and zero if not. That asymmetry is what makes a small probability bet attractive — we don't need to be confident that 4.3%+ is the most likely outcome, just confident enough that the market has under-priced it. ### 4. What could go wrong A cold print is the obvious risk: a softer-than-expected services line or a downward revision to last month's report could pull the headline figure well below 4.3% and the position expires worthless. We size the basket so that outcome is bearable, and we don't add to it after the print is out — once the catalyst fires, the trade is done. ## Disclosures Backtested results are hypothetical and do not reflect actual trading.
