In Biteye’s previous article, we introduced the basic arbitrage logic of prediction markets. (Read more: Dissecting Polymarket’s Five Major Arbitrage Strategies: How Ordinary Players Can Capture Million-Dollar Opportunities?) For advanced traders, Polymarket’s profit core is no longer just event prediction, but systematic arbitrage based on information transmission order, contract interpretation boundaries, and probability mismatches.
While ordinary investors obtain delayed information via social media, professional traders monitor raw data sources and complete pricing deviations before market consensus is reached.
This article by Biteye will deepen your understanding:
The price fluctuation logic of prediction markets can be simplified as: Real Event -> Raw Data Stream -> Social Media -> Trader Decisions -> On-chain Order Matching -> Price Movement
The earlier you access the raw data stream, the greater your absolute price advantage.
Blogger @QuantVela: Each Polymarket market corresponds to a highly authoritative resolution source, but these sites often lack public APIs and have incomplete documentation. In such cases, sending emails to inquire can connect you directly to source data.
In prediction markets, the order of information on the timeline is highly valuable. The closer to the front, the more likely you are to replicate “formula news” and become the market’s Vida.
In prediction markets, many people love to “sweep the tail,” making large bets when victory seems 99% certain for a tiny 1% profit. But this approach can wipe out dozens of profits with just one reversal.
Tail-end trading isn’t impossible, but it requires market selection.
The core of prediction market prices is the pricing of possibilities. When an event reaches the end, there’s insufficient time for variables to occur.
For example:
Or: the fact has already happened and been announced, but due to procedural delays, the market remains unresolved.
Effective tail-end trading isn’t about betting on probabilities but about exploiting physical impossibilities. Only when time can no longer support any variables (like reversals or comebacks) does this tiny profit become truly certain.
In BTC’s 15-minute rise/fall prediction markets, buy the undervalued side when BTC’s price surges or drops rapidly, then hedge by buying the opposite side, ensuring total cost stays below $0.95 to lock in 5-10% profit.
For example: When BTC’s price drops, the probability of an upward move within 15 minutes also drops due to panic, leading to irrational retracements. Probabilities follow price declines.
At this irrational price point, buy the Up position. When the market stabilizes, buy the Down position at normal prices, ensuring both positions are balanced and total cost remains below $0.95.
This strategy is similar to grid trading: buy low, sell high, without guessing direction, using bidirectional positioning to turn volatility into price differences.
Tip: This strategy is suitable only for ranging markets. In recent trending down markets, some still bet on Up, causing weak correlation between probability and price, often leading to Up price premiums.
In Biteye’s previous article, we briefly mentioned this strategy: in newly launched or illiquid markets on Polymarket, arbitrage opportunities exist by placing buy and sell orders to profit from the spread.
Additional notes:
Bots see the current bid price, e.g., 3 cents → immediately buy at bid.
Then sell at ask, e.g., 4 cents. Each time locking in about 1 cent profit.
The essence of this strategy is providing liquidity in low-liquidity markets, stacking small profits through high-frequency micro-spread captures.
Monitor Binance spot or futures order book in real-time, focusing on bid-ask distribution, depth, and buy/sell imbalance, to judge the short-term trend of the 15-minute BTC rise/fall prediction market.
When the order book shows a strong short-term directional signal, the bot quickly buys the undervalued side (e.g., buy Up), then sells when Polymarket price corrects and reflects the true probability.
This strategy exploits the high liquidity market (Binance) data ahead of the low liquidity market (Polymarket), harvesting the delay in price discovery.
Trader anoin123, with a total profit of $1.45 million, demonstrates a highly profitable logic in prediction markets: harvesting collective panic.
He targets binary markets with clear deadlines, such as:
When headlines, social media panic, or tense situations escalate, retail traders flood into YES, pushing the YES price to 70–95¢, while NO is heavily depressed (often to 5–40¢).
People tend to overestimate the probability of extreme events in the short term and underestimate the inertia of maintaining the status quo in geopolitics.
He doesn’t bet on geopolitical outcomes themselves but on market overreactions returning to rationality—that nothing will happen.
In short: he’s betting on the irrational premiums caused by market panic.
In Biteye’s previous post, we discussed “news trading” in subjective prediction markets, and this time we introduce “information gap trading.”
chungguskhan places heavy bets only on highly certain events, with six-figure positions.
These are not blind bets but capturing the price difference within the window between “little information known” and “market consensus.”
For example: regulation has been approved, but the official announcement will come hours or days later.
Tip: Focus on “Source,” “Definition,” and “Timezone.” Beware of “word games”: especially regarding “airdrop,” “ban,” “launch,” etc. Always clarify whether it refers to “announcement” or “actual implementation.”
In Polymarket, a common misconception for beginners is: “I think 99% will happen, current price is $0.99, so this is free money.” In reality, this is often the start of losses.
Polymarket’s probabilities reflect trader consensus, not objective likelihood.
If the Yes price is 0.99 and the actual probability is also 99%, your expected return on betting Yes is 0, not 1.
Tip: Look for mispricings—only when you believe the actual probability is 90% but the market prices it at $0.70 does the 20% discrepancy become your profit.
The biggest risk is unexpected losses at settlement due to fuzzy rules, unreliable sources, or disputes. It’s advisable to sell early while market sentiment is still volatile.
Polymarket once had a market: Will TikTok be banned before January 19, 2025?
In fact: On January 19, 2025, major app stores (Apple, Google) did remove TikTok, and the government officially initiated a ban, preventing new downloads and restricting existing users. In common sense, this counts as a ban.
But UMA’s rules define a ban very strictly—must be completely inaccessible or cease operations entirely.
UMA voters ultimately decided this didn’t meet the strict definition of a ban. As a result, all YES bets lost, even though in the physical world the ban was already in effect.
Before betting, always read the market rules.
Polymarket once had a market: Will Monad airdrop in October?
On October 9, Monad officially announced: The airdrop claim website will open on October 14. Theoretically, the YES price for Monad’s October airdrop should rise to $1, but it didn’t.
The reason: the rules state that only when users claim the airdrop and it becomes tradable is it considered a YES. As a result, YES surged on news trading but then fell back.
Tip: Pay attention to “Source,” “Definition,” and “Timezone.” Beware of “word games,” especially regarding “airdrop,” “ban,” “launch,” etc. Clarify whether it means “announcement” or “actual completion.”
Similar to Biteye’s previous post: “According to Dune data: The accuracy rate 4 hours before settlement on Polymarket is 95.4%.”
Someone found that 79.6% of Polymarket markets are identified as NO.
This isn’t unfounded: mathematically and logically, NO encompasses more possibilities than YES.
Seeing a wallet with 99% win rate or huge PnL on the leaderboard, your first reaction shouldn’t be copy trading. Avoid blindly following prediction market traders.
Many high-win-rate wallets are essentially delayed arbitrage bots; their profits only exist within milliseconds windows. Blind copying just provides liquidity for these bots.
Tip: Before copying, check trading frequency, individual trade size, and historical drawdowns. Subjective traders may perform better.
If Biteye’s previous post introduced the beginner’s path into prediction markets, this deep dive aims to reveal the trading strategies behind Polymarket.
From first principles, prediction markets are fundamentally about pricing information flow and rewarding cognitive depth.
After dissecting numerous Polymarket cases, Biteye observes that Polymarket is forming a unique ecosystem: it fairly rewards everyone with a strategy. Here, each person’s approach is different:
Despite different focus areas and strategies, these winners share a common trait: they never gamble on luck, only on event certainty.
The most fascinating aspect of prediction markets may be this: they provide a direct path to monetize cognition.
May you build your own certainty model in the probabilistic market.
