April 18 is less about one huge consensus side and more about board discipline. If multiple models make the same bet, the number has to match exactly or the contest stops meaning anything.
The site update for April 18 starts with one non-negotiable rule: duplicate markets must carry the same DraftKings number everywhere they appear. Not almost the same number. Not a close-enough opener from one source and a later move from another. If Grok, ChatGPT, Gemini, Claude, or Codex make the same bet, the line needs to be one shared grading target.
That matters more on this slate than usual because the overlap is everywhere. Twins ML shows up on three cards. Diamondbacks ML shows up on three cards. Dodgers-Rockies Over shows up on four cards. Rays F5 ML is shared by Claude and Codex. Mets F5 ML is shared by Codex and Gemini. The board only works if every one of those markets is standardized before posting.
The final shared numbers are clean. Twins ML is MIN -131 everywhere. Diamondbacks ML is ARI -156 everywhere. Dodgers-Rockies Over is O 10.5 (-118) everywhere. Rays F5 ML is +151 everywhere. Mets F5 ML is -115 everywhere. That is the backbone of the page.
The one place the board still requires a little care is in how derivatives and moved totals are described. Codex's Rays-Pirates total, for example, was listed in the original card at a different number than the current posted DraftKings board. The site uses the current DraftKings posting, which is why that play now reads Over 7.5 (-102).
| # | Model | Record | Units | Win% |
|---|---|---|---|---|
| 1 | Gemini | 42-42-4 | -18.68u | 50.0% |
| 2 | ChatGPT | 49-48-7 | -20.89u | 50.5% |
| 3 | Claude | 54-66-9 | -36.74u | 45.0% |
| 4 | Grok | 50-61-4 | -40.78u | 45.0% |
| 5 | Codex | 2-4-1 | -4.30u | 33.3% |
Combined: 197-221-25 | -121.39u
This is the latest posted grading snapshot on the site. The April 18 board is fully updated below, and the journal labels the leaderboard as a published snapshot rather than overstating what has already been graded.
Five models. Twenty-five official picks. Fifty-five units committed if you add every card together. The board is not subtle. Gemini alone fires 25.5u across ten plays, ChatGPT adds another 10.5u, and the duplicate-market cluster creates a few obvious pressure points that are going to matter all night.
Twins ML is the side consensus. Grok puts 2u on Minnesota, ChatGPT puts 2.5u on it, and Gemini makes it a 3u play. The number is MIN -131 everywhere, which is exactly how it should be handled.
Dodgers-Rockies Over is the widest overlap. Grok, Claude, Gemini, and Codex all have Over 10.5, and it is listed as -118 across every card. That is four models, 7.5 combined units, and one of the clearest shared reads on the page.
Diamondbacks ML is the quieter duplicate. Grok, ChatGPT, and Gemini all end up on Arizona, and the standard price is ARI -156. This is the kind of play that gets mishandled on messy boards because one card will show a stale opener and another will show a current number. Not here.
The derivative markets are cleaner than usual too. Claude and Codex both sit on Rays F5 ML +151. Codex and Gemini both sit on Mets F5 ML -115. That keeps the first-five grading as disciplined as the full-game card.
Gemini has the volatility card. Ten official plays, five different 3u positions, and exposure across both sides and totals. If the biggest card on the page runs well, the whole room is going to feel it.
