The Financial Rules of Baseball
2026 Luxury Tax Thresholds
The Competitive Balance Tax starts here. Penalties scale with how far over you go — and how many years you've been over.
What Makes MLB Different
MLB lets you go as high as you want — you just pay penalties. This creates a different strategic game than the NFL or NBA.
July 31. No other sport has a moment like it. Sellers clear payroll and rebuild. Buyers go all-in on a championship window. AiMLB GM models the whole thing.
