The Overreaction Window: How to Trade the First 10 Minutes After News Breaks

The Market Is Not a Computer

When a headline drops — a candidate withdraws, a Fed member says something spicy, a hurricane shifts west — prediction markets don't smoothly reprice to the new fair value. They convulse. Prices overshoot, snap back, overshoot again, and eventually settle somewhere that may or may not resemble the truth.

That first 10-minute window after news breaks is where most of the money is made and lost. Not because the news is unclear, but because humans are trading it.

What Actually Happens in the First 10 Minutes

The sequence is almost always the same:

Seconds 0-60: Headline hits. A handful of fast accounts (bots, sharps with alerts, people who happened to be looking) start hitting the book. The spread widens as market makers pull quotes to figure out what's going on.

Minutes 1-3: The overreaction. Retail sees the headline on Twitter, sees the price already moved, and piles in *chasing* the move. This is where you get YES contracts blowing through fair value by 5-15 cents on genuinely ambiguous news.

Minutes 3-7: The fade begins. Sharps who read the actual article (not just the headline) start taking the other side. Price wobbles.

Minutes 7-10+: Something like equilibrium. Not fair value — just the price where the panicked buyers have run out of ammo and the fade is exhausted.

The Headline vs. The Content

Here's the edge: most people trade the headline. Almost nobody reads the article in the first three minutes.

"Fed Official Suggests Rate Cut Delay" moves the market. But the article says one non-voting member mentioned it as a possibility in a Q&A after a speech about something else. That's not news. That's noise dressed up as news.

Your job in minute one isn't to trade. It's to read. If the headline overstates the content, you fade. If the headline understates the content, you follow. If they match, you probably don't have edge and should sit out.

The Two Questions

Before you click buy, answer both:

1. Is this information already priced in? If the market moved 8 cents on a headline that was basically leaked yesterday, the news isn't the news — the confirmation is. That's usually a smaller move than people trade it as.

2. Does this change resolution or just sentiment? Prediction markets resolve on outcomes, not vibes. A poll showing your candidate down 3 points feels bad but might not meaningfully change their 60% win probability. A candidate dropping out of the race changes everything. Weight your reaction accordingly.

Where People Get Wrecked

The classic disaster is trading the second headline. Original news hits, market moves. Then a follow-up headline restates the same news in punchier language, and traders who missed the first move panic-chase the second one — at a worse price, for the same information.

Another killer: trading during a liquidity vacuum. When market makers pull quotes, the spread can go from 2 cents to 15 cents. You take out the offer at 72, and thirty seconds later the market is 58/62. You didn't have edge. You had bad fills.

The Discipline

Set alerts. When news breaks on a market you follow, your first action is to open the source article, not the order book. Give yourself a rule: no trades in the first 90 seconds unless you had a pre-written thesis for exactly this scenario.

The traders who make money on news aren't faster than the bots. They're more patient than the humans. The overreaction window closes on its own. Your job is to be there with a clear head when it does.
