REPLAY CASE · CRYPTO · RESOLVED JANUARY 10, 2024

The First Spot Bitcoin ETF Approval

On January 9, 2024, the SEC's official Twitter account posted that spot Bitcoin ETFs had been approved. Forty minutes later, the SEC retracted the tweet, claimed they had been hacked, and Bitcoin fell 6% in twelve minutes. The next day — January 10, 4 PM ET — the actual approval landed. By the time it did, the market had spent fourteen months building toward this exact outcome. The price chart of the spot-ETF approval market on Polymarket is a study in how markets price an event that everyone knows is coming but no one knows exactly when. This case teaches what 'priced in' really means: most of the move had already happened. The remaining move was about the precise timing.

WHAT YOU'LL LEARN

"'Priced in' is a real concept. When an outcome is widely expected and the market sits at 95% for weeks, the remaining edge is about timing and exact details, not the binary outcome."

· You'll watch the market process information in real time from January 9, 2024 through January 10, 2024
· You'll trade with $100 in simulated USDC. No real funds move at any point.
· After the replay ends, you'll see a debrief: what your decisions would have returned, where you anticipated the move, where you chased.

CONTEXT

What was knowable at the time.

What was knowable on January 9

· The SEC had until January 10 to rule on the BlackRock and Fidelity applications.
· Polymarket's "Spot ETF approved by Jan 15" market had been trading at 92-95% for two weeks.
· Bloomberg's Eric Balchunas and James Seyffart had assigned 90%+ odds in late December.
· The fake @SEC_News tweet at 4:11 PM ET on January 9 said "Today the SEC grants approval for #Bitcoin ETFs." The price spiked from 94% to 99% in 90 seconds.
· 40 minutes later: SEC retracted, claiming compromise. Price dropped to 88%. Bitcoin spot fell from $47.5K to $44.5K.
· January 10, ~3:45 PM ET: Multiple outlets reported approval imminent. Price climbed to 99% before the official release.
· Real approval published at 4:01 PM ET. The market resolved YES immediately. Bitcoin briefly hit $49K then sold off on classic "buy the rumor, sell the news."

Replay sessions use simulated funds against historical Polymarket price data. No real USDC moves at any point during a replay. Your simulated calibration is a training tool, not a promise of how you'll do with real money.
