How to Track Prediction Market Bets Live on PredTerminal 2026

During breaking news, the first minutes often decide whether you get a good entry or watch the spread close. This step-by-step workflow shows how to track prediction market bets live on PredTerminal across Polymarket and Kalshi, starting with whale trade spikes and ending with confirmation before you execute. You’ll also learn how to verify whale-driven price moves, scan for arbitrage gaps, and manage fast-market risks like thin liquidity and false signals. By the end, you’ll have an alert + review loop that keeps you ahead of the “moved already” crowd.

Why “breaking news timing” matters in prediction markets (and where traders miss the move)

Breaking news creates instant repricing risk. The fastest money often isn’t retail—it’s whale-sized participants reacting to new information, shifting odds before most traders even refresh. If you wait for confirmation from the “main” price only (or a single exchange), you can miss the window when the spread is still favorable and liquidity is thin.

Most traders also miss two key dynamics:

1. Cross-platform lag: Polymarket and Kalshi can move at different speeds as orders hit their books. If you only watch one venue, you may buy at a locally “fair” price while the other venue is still lagging.
2. Signal-to-execution delay: Whale activity may spike before the order book fully reprices. Traders who don’t verify with price confirmation (and sometimes arbitrage gaps) risk entering after the edge disappears.

A practical breaking news playbook should therefore be timing-first: monitor whale flows → verify market price impact → check cross-exchange gaps → then decide on entry and sizing.

Set up your PredTerminal dashboard for real-time coverage (featured vs full markets, cross-platform view)

Before breaking news hits, you want your workspace ready to answer three questions within seconds:

• What market is moving?
• Which exchange is leading vs lagging?
• Is the move supported by large trades (whales) or just noise?

Configure a cross-platform view

PredTerminal provides a unified Polymarket + Kalshi dashboard with real-time odds/prices, plus a whale bet stream and arbitrage scanning. For breaking events, prefer a cross-platform layout: keep Polymarket and Kalshi price movements visible for the same theme (e.g., election outcomes, regulatory decisions, geopolitical escalation).

Featured vs full markets (know what you can see)

Free users typically see featured markets only, and the whale stream may show 1-hour delay. If you’re serious about “live during breaking news,” you should assume you need access to full markets and the real-time whale bet stream (via WebSocket) to avoid acting on stale signals.

Even with full coverage, don’t drown in markets. Use category focus (Politics, World Events, Economics, Science) and keep your watchlist lean to the event types you actually trade.

Turn on the right alert channels

PredTerminal supports email alerts, and for paid tiers it also includes sound and browser push notifications, plus arbitrage opportunity alerts. For breaking news, notifications should be reserved for what you can act on immediately:

• whale activity thresholds (e.g., $10K+ trades)
• market moves for your selected markets
• detected arbitrage gaps between Polymarket and Kalshi

Live workflow: from whale trade spike to actionable entry (smart conviction → arbitrage gaps → price confirmation)

A strong “breaking news” workflow is iterative and fast. Here’s a step-by-step process you can run during real time.

Step 1: Detect the trigger—use the predterminal real-time whale bet stream

When a major headline drops (e.g., “central bank unexpected rate decision,” “sudden ceasefire talks,” “player injury affecting tournament odds”), open PredTerminal and scan for:

• whale trades as they happen (large $ amounts)
• clusters of trades in the same direction
• repetition across related markets (same underlying event, different contract structures)

PredTerminal’s live whale bet tracking and whale bet stream are designed for this: instead of guessing which contract “feels right,” you start from where institutional-sized capital is actually moving.

Example context: Suppose Polymarket has a contract like “X country will announce Y sanctions before date Z,” and Kalshi has a corresponding “Announcement occurs by/after date.” A sudden $20K+ buy on one side often precedes visible price movement, especially on the exchange that processes the whale order first.

Step 2: Translate whale direction into thesis—smart conviction signals

Whale activity tells you what changed. “Smart conviction” signals help you judge whether it’s likely to persist or revert.

Use smart conviction to answer:

• Is the whale move aligned with broader flow (not a single odd trade)?
• Are multiple top traders/copy signals converging on the same outcome?
• Does the move fit a known narrative revision triggered by the news?

This is where many traders overfit: they see a whale trade and instantly assume the thesis is correct. Smart conviction helps filter for momentum vs one-off liquidity grabs.

Step 3: Check arbitrage gaps—where the edge often lives

Once you see directional whale flow, immediately run an arbitrage scan. PredTerminal can detect price gaps between Polymarket and Kalshi. During breaking news, arbitrage windows can appear because one venue reprices faster than the other.

Practical rule: don’t chase the “most moved” price. Chase the mispricing across venues.

Example context: If Polymarket prices “Outcome A” at 58% while Kalshi prices the equivalent at 61%, you may have a gap depending on contract definitions (yes/no, time cutoff, settlement mechanics). PredTerminal’s arbitrage scanner is meant to reduce manual matching errors and speed up the decision loop.

Step 4: Confirm with price impact—don’t enter on whale intent alone

After whale spikes:

1. confirm that the order book/odds follow through (not just a temporary trade print)
2. observe whether small-to-mid traders are joining the move
3. check whether liquidity is tightening (spreads widening can be either dangerous or beneficial for your entry)

PredTerminal’s unified dashboard makes this cross-exchange confirmation easier: you can verify whether the move is happening on both venues or only one.

Step 5: Execute with a “breaking news” sizing plan

Even if the thesis is right, breaking markets punish aggressive sizing:

• spreads can widen unexpectedly
• your entry may become unfillable as the book turns over
• you can get filled but face adverse mark-to-market if resolution timing shifts

Start with a smaller test size, confirm continued pricing consistency for 10–60 seconds (or longer if liquidity is thin), and only then scale.

Risk controls during fast markets: thin liquidity, spread surprises, settlement/resolution traps, and false signals

Breaking news trading isn’t only about speed—it’s about surviving failure modes.

Thin liquidity and spread surprises

When a market reprices suddenly, depth often disappears. You might see a price jump, but the best available fills can be far from the displayed odds.

Controls:

• limit order when possible
• avoid market orders in thin books
• confirm that adjacent prices remain stable for at least a short window

PredTerminal’s real-time pricing helps you spot where the market “jumps then sticks,” which can indicate either real repricing or a temporary liquidity vacuum.

Settlement/resolution traps (contract mismatches)

Polymarket and Kalshi contracts aren’t always perfect mirrors. Even if they look equivalent, differences in:

• cutoff timestamps
• definitions (what counts as “announcement”)
• who decides/official sources can flip outcomes.

During breaking news, the first headline might be wrong or revised. If the contract resolves based on an official body’s later statement, you need to ensure the resolution criteria match your narrative.

Mitigation workflow:

• read the contract resolution criteria before trading
• only arbitrage between contracts with genuinely comparable definitions
• treat arbitrage as a confirmation layer, not a guarantee

False signals and “whale wash” scenarios

Whale prints can be:

• hedges (not directional conviction)
• test orders
• temporary liquidity provision then withdrawal
• trades reacting to rumor that later gets corrected

Mitigation:

• look for multiple whale trades in the same direction across a short interval
• use top trader leaderboard + copy signals to see if credible traders align
• rely on price confirmation rather than the first print

Settlement and resolution timing risk

Breaking news can change quickly. Some markets settle on “by end of day” outcomes; others hinge on a specific instant. A move that’s correct for one timing window may be wrong for the contract’s actual resolution rule.

If you trade frequently during breaking news, build a checklist:

• is the market tied to a date or a moment?
• can there be revocations or retractions?
• is the outcome dependent on an official publication channel?

Automation & staying ahead: alerts (email/push), notification rules, and what to export for review

Manual monitoring breaks down when news cycles stack. Automation turns your workflow into a repeatable system.

Set notification rules that match your execution speed

Use PredTerminal alerting to avoid constant tab-refreshing. A sensible breaking-news configuration:

• whale bet alert for large trades in your watched markets (or relevant categories)
• arbitrage opportunity alerts only if they involve markets you can truly execute across (not every detected gap)
• market movement alerts tied to your specific contract watchlist, not generic category noise

If you use push/sound notifications, keep thresholds high enough that alerts remain actionable.

Use CSV export for post-mortem and pattern building

After the dust settles, export data to analyze what worked and what didn’t. PredTerminal supports CSV data export for whale trades and trader data.

What to export after major events:

• whale trades you acted on (timestamp, amount, direction, exchange)
• price snapshots around each whale spike
• arbitrage detections that led to execution vs those you skipped
• top trader/copy signal alignment (did your thesis match real top-trader flow?)

Then run a simple review:

• How quickly did price confirm after the whale trade?
• Did arbitrage appear before or after the main repricing?
• Were false signals associated with single large prints or repeated flow?

Build a repeatable “morning/evening” and “during-event” routine

• Before market-moving events: verify your watchlist, notification rules, and category focus.
• During event: follow the loop (whale spike → smart conviction → arbitrage scan → price confirmation → execute with conservative sizing).
• After event: export CSVs and evaluate decision timing.

Over time, this reduces the “feel-based” entries and improves consistency during breaking news.
