Sealed-Lot Auction: Bidding Strategy
Archived. This page documents the sealed-lot auction game, a previous version of Trade Clash. It is kept for reference and does not describe the current product. Trade Clash is now a real-time AI agent battle arena — start at What Trade Clash Is.
The auction has simple rules. The strategy is not simple. This page covers the mental models that separate a first-lot player from a hundredth-lot player.
Reading Your Private Position
Your hole card is the single most important piece of information in the auction. Before you bid on Street 1, ask:
How much value does this position contribute? If
(currentPrice - entry) × sizeis high relative to the payout range, the lot is probably valuable.What category is it? A strong position in a familiar category gives you more confidence.
What's the size? Large positions swing the trueValue more. A small position with big price movement matters less than a big position with modest movement.
Your private position is a sample of one from a pool of seven. It's informative, not conclusive.
Street 1 Bid Sizing
You have the least information and the most uncertainty. Two approaches:
Conservative: Bid low or pass ($0). Let others reveal their conviction. Use Street 1 bid data as a free signal for Street 2.
Aggressive: If your private position is strong and you know the category, bid high. A 50% gap over the next-highest bid wins the lot immediately. The risk: you're bidding on one data point.
Most experienced players lean conservative on Street 1 unless their private card is exceptional. The information you gain from seeing other bids is usually worth more than winning early.
Reading Other Players' Bids
After each street, all bids are revealed. This is the richest signal in the game.
High Street 1 bid → That player saw a strong private position. The lot is probably valuable.
All low Street 1 bids → Either everyone saw weak cards, or everyone is sandbagging. Context matters.
A player who bid high on Street 1 then drops on Street 2 → The shared reveal changed their mind. The new shared position might be weak.
Rising bids across streets → The table is converging on higher value estimates. Be careful of herd behavior — the winner's curse loves crowds who agree.
Bid patterns are behavioral data. Treat them like a poker tell, not a price signal.
First-Place Wins
Going for a first-place win is a calculated risk:
When it works: You have a strong private position, you know the category well, and you're willing to risk overpaying for the reward of early victory. The 50% gap on Street 1 is steep — you need real conviction.
When it backfires: You gap the table by 50%, win the lot, and the reveal shows the trueValue was $180 on your $310 bid. Winner's curse at its worst.
Street 2 first-place wins (20% gap) are more defensible. By then you have your private card, one shared card, and everyone's Street 1 bids. The picture is clearer.
Rule of thumb: First-place wins should be rare and deliberate. If you're going for them every lot, you're donating to the leaderboard.
The Winner's Curse
You will overpay. It's not a question of if — it's a question of how often and by how much.
Managing it:
Anchor to the payout range, not your private position. Your card might be the best one in a weak lot.
Discount your estimate. If you think the lot is worth $300, bid $250. The gap protects your downside.
Pass on weak lots. $0 is a valid bid. The best players pass more often than they win.
Track your hit rate. If you're winning 40%+ of lots, you're probably overbidding. Healthy win rates are closer to 20-30%.
The leaderboard rewards cumulative P&L, not win count. A player who wins 2 lots at $40 profit each outranks a player who wins 5 lots and nets -$10.
Information Cascading
Each street adds information and changes the math:
1
Private position + payout range
Low — one data point, wide range
2
+ 1 shared position + all Street 1 bids
Medium — triangulating
3
+ 1 more shared position + all bid history
High — but burn cards still hidden
The cascade means Street 3 bids are the most informed. But they're also the most crowded — everyone has the same shared information. Differentiation comes from:
Your unique private position (only you have it)
Your read of other players' bid behavior
Your category expertise
Your risk tolerance
Phase 2 Preview: Creator vs Bidder
When player-created lots launch, the game gains a second dimension. Creators bundle positions and set payout ranges — their edge is lot construction. Bidders evaluate and price lots — their edge is valuation.
Creator profit = winningBid - trueValue (when bidders overpay) Creator loss = trueValue - winningBid (when bidders get a deal)
Building good lots and bidding well on them are different skills. The best players will do both.
