How BearBull Works   

BearBull is fantasy sports meets the stock market. Instead of drafting athletes, you draft real US stocks and instead of touchdowns, you're competing on actual market performance.

The Basics

A challenge is a 1-week competition (Monday market open through Friday market close) where players build a stock portfolio and compete for the highest growth percentage. Think of it like a fantasy football league, but for the stock market.

Creating a Challenge

Any player can host a challenge. The host names it, picks a start date, and shares an invite code that they can copy to friends, family, or coworkers. 

Building Your Roster

This is where strategy lives. Each player selects 10 stocks from a curated catalog of ~100 US companies and distributes 100 shares across them. But you can't just load up on one stock — rosters are built around a tier system based on stock price

Each BearBull roster is built using five stock tiers based on share price. You'll draft: 

2 Speculative stocks ($5–$25.99)
3 Momentum stocks ($26–$50.99)
3 Core Holdings ($51–$150.99)
1 Blue Chip stock ($151+)
1 Wildcard stock*

*Which can be any price and is the only tier that allows stocks under $5

 You'll then allocate 100 total shares across your roster within each tier's share limits.

This structure forces balanced portfolios. You can't simply go all in on one stock. Success requires finding the right mix of high-risk opportunities, steady performers, and breakout candidates, with your strategic edge coming from how you allocate shares within each tier.

To keep competition unique, no two players in the same challenge can submit the exact same roster and share allocation. It is first come, first served. If another player has already claimed your combination, you'll need to make adjustments. This rewards original thinking, early roster submissions, and prevents copycat strategies.

How Scoring Works

Once the market opens, rosters are locked and your score begins tracking the real-world performance of your stocks. Each stock contributes to your score based on its percentage gain or loss and the number of shares you've allocated to it. Stocks that rise increase your score, while stocks that fall reduce it.

Scores update throughout market hours, and a live leaderboard lets you track your standing against other players in real time.

Winning

At market close (usually Friday), final prices are captured and the player with the highest growth percentage wins. In case of a tie: highest overall growth first, then whoever had more individual stocks in the green, then whoever submitted their roster earliest.

What You See on Your Profile

Every challenge you play contributes to your career stats: win/loss record, growth percentage history, total challenges played, and win rate. It's your track record as a stock picker — bragging rights included.

Notifications

You'll get notified when it matters: when someone joins a challenge you created, when you have less than a day to lock in your picks, when the challenge starts, when you take the lead, and when results are in! You can customize which notifications you receive in your settings.
