Definition
GPP (guaranteed prize pool) is a DFS contest format where the prize pool is guaranteed regardless of how many entries fill. Payout structure is top-heavy: typically top 15–20% of entries cash, but 50–70% of total prizes go to the top 1% of finishers. This structure requires boom-or-bust roster construction — low-ownership tournament-winning plays beat safe high-ownership stacks. GPPs reward correctly predicting outlier performances, not average projections. Large-field GPPs ($3–$20 entry) offer the highest ceiling and most variance.
Worked Example
$5 GPP, 10,000 entries, $50,000 prize pool. 1st place: $10,000 (200× return). Cash line: top 2,000 entries (20%) win $12 or more. To win 1st, need 6–8 correct differentiated calls vs 9,000+ competitors. Expected value of optimal GPP entry: positive only if lineup construction beats field by enough to offset the heavy top-weighting. Identical roster to 30% of field = near-zero shot at top prizes.
Why It Matters
GPP EV hinges on ownership leverage. Correctly going low on chalk at peak chalk pricing — and being right — creates 10–100× returns. High-owned safe plays guarantee cash-line outcomes but eliminate first-place equity.
