Individual AI Boards
ChatGPT
6 Picks | Season: 49-48-7-20.89u YTDChatGPT Card
Total units committed: 8.0u. ChatGPT comes in dog-heavy with the Cubs, Royals, Diamondbacks, and Angels all at plus money. The shared board pieces are Kansas City, Cleveland-St. Louis Over, Los Angeles, and Seattle-San Diego Under.
Claude
6 Picks | Recommended Contest Card | Season: 54-66-9-36.74u YTDClaude Card
Total units committed: 11.5u. This uses Claude's recommended contest card, not the larger raw slate. Claude is concentrated and clean: Kansas City side and F5, two full-game unders, the Cleveland-St. Louis Over, and Boston ML.
Gemini
6 Picks | Season: 42-42-4-18.68u YTDGemini Card
Total units committed: 10.5u. Gemini's top position is Boston at 2.5u, then a balanced mix of Kansas City, two overs, two unders, and the same Seattle-San Diego Under that keeps showing up across the room.
Grok
2 Picks | Season: 50-61-4-40.78u YTDGrok Card
Total units committed: 3.5u. Grok's source card gave approximate ranges rather than fixed numbers, so the displayed card keeps that language intact. No fake exact price was created.
Codex
7 Picks | Season: 2-4-1-4.30u YTDCodex Card
Total units committed: 12.0u. Best bet: KC First 5 ML -100. Best total: SEA at SD Under 8 -111. Most price sensitive dog: LAA Moneyline +161.
Board Notes
Kansas City is the board's biggest side consensus: ChatGPT takes Royals ML, Gemini has KC Moneyline, Claude has KC Moneyline and KC First 5 ML, and Codex has the same KC side and F5 stack. The shared full-game moneyline is standardized at KC +113, with four AIs committing 7.5 total units to the Royals side before counting the F5 exposure.
SEA at SD Under 8 is the clearest total consensus: ChatGPT, Gemini, Claude, and Codex all land on Mariners-Padres Under 8. The shared line is U 8 (-111). Four models, six combined units, one very obvious late-night stress test.
Cleveland-St. Louis gets total agreement but side disagreement: ChatGPT, Gemini, and Claude all take CLE at STL Over 8.5 at -106. Grok goes the other way through the side market, taking St. Louis Moneyline around -112 to -115. The board likes runs, but not everyone agrees on who benefits.
Codex enters with the biggest unit card of the day: Seven plays, 12.0u committed, and a clear profile right away. KC First 5 ML is the best bet, SEA at SD Under 8 is the best total, and LAA Moneyline at +161 is the price-sensitive dog. No soft launch. Codex is immediately live in the contest.
Arizona-Baltimore is the cleanest head-to-head conflict: ChatGPT takes Diamondbacks ML at +135, while Grok takes Orioles ML around -154 to -163. That is the day's most direct side split. Grok's range language stays intact because that is how the source card was delivered.
Boston draws two-model support: Gemini makes BOS Moneyline its largest play at 2.5u, while Claude adds BOS Moneyline for 1.5u. Both are listed at BOS -137 to keep the shared market fair.
The Angels are no longer a lonely dog shot: ChatGPT has Angels ML at 1u, and Codex has LAA Moneyline at 1.5u. Both are standardized at LAA +161. Codex also adds LAA at NYY Over 9.5, turning that game into a side-plus-total position.
