National League Manager of the Year is a story award. Voters hand it to the skipper whose club most outran what anyone expected of it, which is why our price-blind panel scored this race on August 4 with Atlanta's Walt Weiss on top at 25 percent and Milwaukee's Pat Murphy down at 15.7.
Murphy is 81 cents today. Milwaukee clinched the NL Central on September 15 and carries the best record in baseball, and the market has spent the week since deciding the award is already his. Weiss has fallen to 19, below the number the panel gave him.
That is a 65-point gap on the favorite, and it has widened every time we have looked. It was 55 points a week ago. Ours is the number that is wrong.
The 15.7 We Would Take Back
The panel's reasoning was never that Milwaukee would fade. It was that this electorate discounts sustained excellence — that a manager whose stacked club wins as expected gets less ballot credit than the win column implies.
Applied to a first-year Atlanta manager with a 13-win improvement, that logic was sound. Applied to Murphy, it required voters to punish a third consecutive outstanding season, and nothing in the voting record says they do that. Murphy is chasing a third straight award no manager has ever won, and the panel treated the streak as a headwind when the market has treated it as the story itself.
The August 4 board had one other loud argument: Don Kelly at 16 cents against a 4.3 percent blend. The market conceded that one completely. Pittsburgh finished 75-76 and the contract has no bid at all. One call landed, the bigger one did not, and the bigger one is the reason to read the rest of this page with the panel's number held at arm's length.

Kalshi event KXMLBNLMOTY-26, read September 21, 2026. Seventeen contracts, of which only four carry a bid. Lifetime volume about $468,000. Panel verdicts are frozen from August 4, generated without sight of any price, and have not been re-scored. These are model estimates, not predictions of fact and not financial advice.
Murphy gained 23 points on the day. Weiss lost 10. Craig Stammen is the only new name to arrive, up four to 7 percent on a 2-bid, 5-ask book, which is a quote rather than a price.
Why The Story Award Reordered This Board
Manager of the Year does not reward the best record. Voters reward surprise contenders, first-year skippers who lift a club, dramatic turnarounds. A stacked roster winning as expected gets less credit than the standings suggest.
That single idea held this board together for six weeks. September tested it to destruction.
Milwaukee clinched on September 15, Jacob Misiorowski throwing five scoreless innings in a 5-1 win at Pittsburgh, and the title only went final later that evening when Weiss's Braves finished off the Cubs in Chicago. Milwaukee was 94-57 that night, the best record in Major League Baseball. Atlanta was 89-63 and up five and a half in the NL East.
Murphy's contract opened clinch day at 60 cents and never traded lower. It has not stopped since.
How To Read These Prices
One thing here undercuts everything above it.
Add the 17 asks on this board and you get 121 cents, for an outcome that pays exactly one dollar. Nobody should buy the field — doing that locks in a 21-cent loss — but the 21 cents is the point, because it is the margin sitting inside every single price on the page. Take the midpoints instead and the board sums to 108, down from about 111 a week ago and from under 100 at the end of August.
The reason the number drifts is that most of this board is not really quoted. Only four of the 17 contracts have a bid underneath them. The other 13 show a penny or two of ask that nobody has met, and a mid on a book with no bid is an optical price, not one you could trade. Compare shapes across a board like this, never exact cents.
The panel's blend is not normalized either. It was scored as independent probabilities on August 4 and left alone, which is what makes it gradeable and also what makes a 65-point miss visible rather than quietly revised away.
What Settles It
BBWAA writers vote on a 5-3-1 ballot before the playoffs begin, and the result is announced in November. That timing matters more than it looks: the ballots are in before anything that happens in October can change anyone's mind, so the case Murphy has already made is close to the whole case.
The Murphy contract's rule reads plainly: "If Pat Murphy wins the Pro Baseball National League Manager of the Year in the 2026 season, then the market resolves to Yes."
Our August number stays frozen at 15.7 so it can be graded in public against what the market did next. On this board, what it did next was run 65 points the other way.
