Resolution criteria

This market resolves to YES if any single Major League Baseball (MLB) player records a cumulative total of 10 or more Runs Batted In (RBIs) in official regular season games played from August 26, 2026, through August 30, 2026, inclusive. Otherwise, this market resolves to NO.

• Timeframe: The games must officially start between August 26, 2026, and August 30, 2026, in Eastern Time (ET).

• Scope: The 10 RBI threshold is cumulative across all games played by a player during this 5-day period (including doubleheaders). It does not require a player to record 10 RBIs in a single game.

• Source of Truth: Resolution will be determined using official statistics from MLB.com or the FanGraphs Splits Leaderboard filtered for the custom date range of August 26, 2026, to August 30, 2026.

Background

Driving in 10 or more RBIs over a 5-day span is a notable offensive hot streak. For context, during a typical week in the 2026 MLB regular season, top-performing batters frequently collect double-digit RBIs over a 7-day period; for instance, Jordan Walker logged 12 RBIs during a week in mid-August 2026, and Dansby Swanson and Junior Caminero co-led a week in late June 2026 with 15 RBIs.

In contrast, achieving 10 RBIs in a single game is one of the rarest feats in baseball history. Pittsburgh Pirates first baseman Ryan O'Hearn became just the 17th player in MLB history to drive in 10 runs in a single game when he did so on July 7, 2026. This market, however, tracks cumulative performance over the specified five-day window.
