Polymarket Knew Before Wall Street. So I Tried to Trade It.

Summary

The video tests whether Polymarket prediction-market odds lead traditional financial markets—and whether traders can profit by following them. Its conclusion is that Polymarket can be a useful gauge of what people believe, but its odds generally did not provide a reliable trading signal once costs and timing were considered. The clearest apparent lead occurred while futures markets were closed over weekends, but the resulting price gap was already reflected when trading reopened.

How the analysis worked

On Polymarket, a “yes” share pays $1 if an event happens and nothing otherwise. A share priced at 70 cents is treated as roughly a 70% implied probability.

The analysis covered:

• 20 Fed meetings from May 2024 to September 2026, with $3.5 billion wagered across those markets.
• 2024 U.S. election night, minute by minute; the video cites roughly $1.5 billion on the election market.
• 154 war-and-peace markets, including Iran, Venezuela, and Russia–Ukraine.

Polymarket odds were compared with futures in crude oil, gold, Nasdaq, 10-year Treasury notes, euros, and yen.

Findings by market

Federal Reserve and Treasury futures

• The Polymarket favorite was correct the day before all 20 Fed decisions in the sample. For a rate increase in September 2026, the probability reportedly rose from 53% a week beforehand to 87.5% the day before.
• In September 2024, expectations shifted late: a half-point cut had been favored the previous day, but five minutes before the announcement, the probability of a quarter-point cut was 56%.
• Comparing 86,400 ten-minute windows in the 30 days before meetings, the analysis found that Polymarket odds and 10-year Treasury futures tended to react in the same ten-minute interval. The odds did not provide a subsequent directional signal.
• A strategy that traded Treasury futures within one minute of a sharp odds move and held for 10, 30, or 60 minutes lost money in each case after commissions and slippage. The best win rate was 48%, which the video says was insufficient after costs.

2024 election night

• Trump’s Polymarket odds rose from 61% at 6 p.m. to nearly 100% by the following morning.
• Futures appeared to move first. At 10 p.m., Polymarket gave Trump an 83% chance, while the Nasdaq had already risen 1.1%. It gained only another 0.1% between 10 p.m. and midnight.
• The video says futures moved roughly 10–30 minutes ahead of Polymarket odds that night, while noting that one election is not definitive proof.

War-and-peace markets and oil

• The study identified about 200 instances where war-and-peace odds rose by at least 10 percentage points within ten minutes while oil was trading.
• Oil and odds moved in the same direction during the jump. Before the jump, there was no reliable pattern; afterward, oil continued in the predicted direction only about half the time.
• On June 23, 2025, oil fell about 9% from noon to 4 p.m. after Iran fired missiles at a U.S. base in Qatar. Polymarket’s ceasefire probability ranged from 8% to 30% during the day, then rose to 81% after Trump announced a ceasefire. The video says oil had already priced in peace hours earlier.
• A more selective backtest—trading oil one minute after odds jumped 20 points or more, then holding for 30 minutes—showed 59 trades and a reported $8,875 profit after expenses. However, the result was highly concentrated:
  • One trade on April 17, 2026 contributed $6,885. The probability of a U.S.–Iran meeting rose from 35% to 70%, while oil fell $7 in half an hour.
  • Excluding that trade left $1,990; removing the top three trades produced a $2,780 loss.
  • Holding for one hour resulted in a $940 loss; holding for four hours resulted in an $11,335 loss.
  • The video says only 1% of random logins produced a comparable result and warns that the apparent strategy depends heavily on a few outliers.

Weekend signals

• Futures markets close over the weekend while Polymarket continues trading. Across 86 weekends with active war-and-peace markets, oil opened in the direction of the odds change on 16 of the 18 weekends when quotes changed the most.
• The video’s February example describes Polymarket odds jumping from 35% to 79% in ten minutes, then to 98% over the next 40 minutes, while oil was closed. Oil reopened 41 hours later and rose 8%.
• However, the video argues that traders cannot capture the weekend move directly because the information is reflected in prices by the time futures reopen. Buying or selling oil at Sunday’s open in the direction of the weekend odds and holding until Monday performed no better than a random choice. In the cited February example, oil moved from $72.86 at Sunday’s open to $71.24 by Monday afternoon; a trade in the direction of war lost money.

Key takeaway and cautions

The video characterizes Polymarket as a “thermometer,” not a crystal ball: its odds quantify market beliefs, but generally did not lead tradable moves in bonds, equities, or oil.

The video cautions that the apparently profitable oil strategy was fragile and dominated by a few unusually large trades. Trading costs, slippage, timing, and dependence on outliers matter.
