How it works

Sportfolio Golf is a stock market game based on the 2026 Open Championship at Royal Birkdale (Jul 16–19). Every golfer in the field can be bought, priced by their leaderboard position. As the tournament unfolds, prices shift. Buy low, sell high.

Starting out

• Each player starts with $10,000
• You must invest at least 75% ($7,500) before Round 1 begins
• Pre-tournament: golfers priced based on betting-odds tiers, from $1.00 to ~$2.65
• After Round 1: prices snap to leaderboard position — last place $1.00, each step up is 1% more, so the outright leader is worth several times the floor price

Trading windows

• Pre-tournament — from launch until Round 1 begins
• After Round 1 — window opens, then closes before Round 2
• After Round 2 — window opens, then closes before Round 3
• After Round 3 — final window, then closes before Round 4
• No trading during rounds or after Round 4 finishes

Rules

• Maximum 25% of your portfolio value in any single golfer per trading window
• Brokerage fee of 1% of your portfolio value is charged on every buy or sell
• Golfers who miss the cut drop to a base price of $1.00 — they can still be sold, and the cash can be reinvested into active players
• Every golfer in the Open Championship field is tradeable — no restricted list
• Equal scores = equal leaderboard position = equal price
• Highest portfolio value at end of tournament wins

In-game price scale

After scores are entered, prices recalculate based on leaderboard position:

• Last place = $1.00
• Each position up = previous × 1.01
• Players on equal scores are ordered based on whatever order they are listed on the official The Open Championship website
• The outright leader's price scales with the size of the field — a bigger field means a bigger gap between 1st and last
