Read the Tape

What it does

Read the Tape is a daily prediction game where players forecast the direction of five S&P 500 stock charts. Each day, all players receive the same five one-day charts. Players call each chart UP or DOWN and select a confidence level: low, medium, or high. The charts then resolve over the following five days. Confidence levels determine stake size from a shared $10,000 paper money pool. Results are posted and compared against a benchmark called the Monkey Index, which tracks eleven random coin flips at low confidence.

Who it is for

The game targets people interested in chart reading and stock prediction. It appeals to traders and chart enthusiasts who want to test their prediction skills in a competitive, gamified format. The shared daily charts and leaderboard create a community of players competing on equal footing.

Pricing

The site does not show prices. Players use $10,000 in paper money allocated from a shared pool each day.

How it stands out

Read the Tape uses a clever benchmark. Instead of comparing players to random chance or a simple 50/50 baseline, it measures performance against the Monkey Index—a deliberately naive strategy of coin flips. This makes winning tangible: beating random guessing is the bar to clear. Early data shows players systematically underperform this baseline, calling tops more often than reversals occur, with down calls succeeding only 31% of the time against 60% upside resolution. The game also emphasizes immediate feedback, with results resolving within five days rather than requiring long holding periods. The interface supports social sharing and challenge mechanics, turning predictions into shareable moments.

What a founder should check

Anyone building a competitor should verify whether the Monkey Index benchmark is actually predictive and engaging enough to retain players long-term, or if the novelty wears off once players accept they cannot consistently beat random. Second, investigate whether the paper money model drives genuine engagement without real financial stakes—does removing money pressure reduce prediction quality or competition intensity? Third, examine whether the five-chart daily constraint creates network effects strong enough to sustain an active community, or if players need more frequent interaction points to stay invested.
