Here’s the latest I can provide based on recent reporting up to 2026, with citations inline after each claim.
Rory McIlroy’s caddie earnings have been a topic of several outlets, with reports highlighting substantial payouts linked to McIlroy’s tournament wins and high prize money in major events. For example, outlets in 2025 discussed Harry Diamond earning around $870,000 in 2025 from McIlroy’s winnings and bonuses, driven by a share of McIlroy’s prize money at events like The Players Championship and Pebble Beach Pro-Am. This was framed as Diamond’s share typically ranging around 5-10% of McIlroy’s winnings, depending on the event outcome.[1]
In 2025, Golf Monthly and other golf outlets echoed the narrative that Diamond’s earnings are heavily influenced by McIlroy’s performance, including wins that year. One article noted a potential caddie share around 7-10% at various events, with higher percentages possible for wins. Another piece summarized Diamond’s likely take from the year’s results, including event-by-event estimates and typical payout structures.[6][7]
Masters and other major results in 2025-2026 continued to be highlighted for large caddie paydays tied to McIlroy’s success. Reports around McIlroy’s Masters wins in 2025 and 2026 often stated that the caddie’s payout increases markedly for major wins and high finishes, with some outlets noting projected or reported figures in the high five- to six-figure ranges for those events.[4][5][8][9]
For broader context, analyses of McIlroy’s 2025 season, including multiple wins and near-wins, fed into estimates of Diamond’s total earnings for the year, sometimes citing total caddie earnings in the low-to-mid seven figures depending on win bonuses and additional event-specific splits.[3][6]
If you’d like, I can pull the very latest specific figures for Diamond’s 2026 Masters run or annual total with sources and a brief summary of the payout mechanics. Also, I can compare different outlets’ reported estimates for 2025 to show how figures are derived and why they vary.
