What Does the Blue Arrow on Kalshi Mean? (And Why It Confuses Traders)
Confused by the blue arrow on Kalshi combos? Learn what scalar settlement means, how it changes your payout, and why Kalshi’s UI is failing new users.
If you have ever searched for what a blue arrow means on Kalshi, you are not alone. Many users discover the symbol after building a combo and then struggle to understand why one leg shows a blue arrow instead of a green checkmark or red X.
The short answer is this:
A blue arrow means that the leg settled as a scalar value (somewhere between $0 and $1) instead of settling as a simple Yes/No result.
That partial value is then used in the combo’s settlement calculation. The combo does not automatically receive a full payout, but it also does not necessarily fall to zero. Kalshi’s Help Center specifically states that the combo payout is calculated by multiplying the settlement value of every underlying position.
Kalshi Combos Explained
To understand the blue arrow, it helps to understand what a Kalshi combo is.
A combo allows you to combine multiple eligible event-contract positions into one custom position. It may resemble a parlay, but it is created and traded through Kalshi’s exchange infrastructure rather than through a conventional sportsbook.
For example, a combo could contain:
Leg 1: Yes on “Player X scores at least 20 points.”
Leg 2: Yes on “Team Y wins.”
Leg 3: Yes on “The total score exceeds 215.5 points.”
A combo has its own market and order book. Kalshi says combo prices are generated through a Request for Quote (RFQ) process: a user submits a request, other participants provide quotes, and the combo can fill if a quote is accepted. Quotes are live, may change before execution, and are not guaranteed to be available.
The maximum payout is usually $1.00 per combo contract. If every underlying position settles at $1.00, the combo pays $1.00. If any position settles at $0.00, the entire combo pays $0.00.
What the Blue Arrow Indicates
A blue arrow next to one of your combo legs indicates that the position settled scalar.
Scalar settlement means the leg was assigned a value between $0 and $1 rather than a definitive $1.00 win or $0.00 loss. For instance, a leg could settle at:
$0.25.
$0.50.
$0.70.
$0.85.
The exact value depends on the rules of the underlying market. It is not automatically the same for every market and should not be guessed from the icon alone.
Kalshi says scalar settlement typically occurs because of a DNP or another type of partial resolution. The market’s individual rules determine how the adjusted value is established.
Example
Suppose a player is included in a combo but does not play. The relevant market rules may provide for settlement at a last traded or fair-market value rather than at $0.00 or $1.00.
If that player-related leg settles at $0.70, while the other two legs settle at $1.00, the combo payout is:
$0.70×$1.00×$1.00=$0.70\$0.70 \times \$1.00 \times \$1.00 = \$0.70$0.70×$1.00×$1.00=$0.70
The combo therefore pays $0.70 per contract, not the full $1.00 and not automatically $0.00.
Common Reasons for Scalar Settlement
The blue arrow can appear when the underlying market has a rule for handling an outcome that is neither a normal win nor a normal loss.
Did not play
A player may be listed in a sports combo but fail to participate because of an injury, late scratch, illness, suspension, or coaching decision.
Kalshi says that if a player does not play, the position is handled according to the underlying market’s rules. In some cases, this can result in a last-traded or fair-market value rather than a binary settlement.
Partial resolution
Some markets contain provisions for situations in which the event is only partly completed or cannot be determined through the normal Yes/No process.
The exact treatment depends on the market’s rules. A partial resolution might result in a value such as $0.50, but users should not assume that every unusual outcome will be settled at 50-50.
Market-specific settlement provisions
Every leg in a combo remains subject to the rules of its underlying market. This means two seemingly similar markets can treat an injury, cancellation, postponement, or unavailable participant differently.
Before trading, open the market’s full rules and look for sections covering:
Player participation.
DNP or late scratch scenarios.
Injuries and ejections.
Postponements and cancellations.
Official data sources.
Determination timing.
Fair-value or non-standard settlement.
Kalshi’s Help Center also notes that once a player has taken at least one snap, a market may settle according to the player’s actual statistics despite an in-game injury, ejection, or other removal. The specific market rules control.
How Combo Payouts Are Calculated
The basic formula is:
Combo payout=Leg 1 value×Leg 2 value×⋯×Leg n value
Examples:
Leg values | Combo payout |
|---|---|
$1.00 × $1.00 × $1.00 | $1.00 |
$0.70 × $1.00 × $1.00 | $0.70 |
$0.50 × $0.80 × $1.00 | $0.40 |
$0.00 × $1.00 × $1.00 | $0.00 |
This is why a scalar leg matters financially. It reduces the maximum payout in proportion to its settlement value.
A blue arrow does not mean the combo has been canceled, refunded, or declared invalid. Kalshi states that the combo is not simply returned when a leg settles at a non-standard value; instead, the payout is recalculated using the product of all leg values.
Why the Symbol Confuses Users
The blue arrow is easy to misinterpret because many users expect only two possible outcomes:
Green checkmark: the leg won.
Red X: the leg lost.
A blue arrow introduces a third possibility: the leg settled at an intermediate value.
The icon also does not show the reason for the scalar settlement. It may reflect a DNP rule, a partial-resolution provision, a fair-value adjustment, or another condition defined in the underlying market. Users must open the relevant market and inspect its rules to understand how the value was determined.
This creates a genuine communication problem. A short tooltip explaining “Scalar settlement: this leg resolved between $0 and $1. Open market rules for details” would make the result much easier to understand.
The Financial Impact
The blue arrow is not merely a display issue. It can change the amount paid on the combo.
Consider a three-leg combo purchased for $0.20 per contract. If all three legs settle at $1.00, the gross payout is $1.00, and the gross profit is $0.80 before fees.
If one leg instead settles at $0.50, the combo payout becomes:
$0.50×$1.00×$1.00=$0.50\$0.50 \times \$1.00 \times \$1.00 = \$0.50$0.50×$1.00×$1.00=$0.50
The gross profit would be $0.30 before fees, assuming a purchase price of $0.20.
The important distinction is that scalar settlement does not necessarily mean the user’s original prediction was simply wrong. A leg may have been affected by a player’s non-participation or by a special settlement rule rather than by the event occurring in the opposite direction.
How to Check Before Trading
Before placing a combo, follow these steps:
Open each underlying market.
Read the full rules, not only the market title.
Check the treatment of DNPs, injuries, cancellations, postponements, and partial outcomes.
Confirm the official data source and determination time.
Review the quoted combo price and the maximum payout.
Check whether the quote is live and whether the order has actually filled.
Account for trading fees and the possibility of a scalar settlement.
Do not assume that an unavailable or non-participating player automatically causes a refund.
Kalshi also notes that combo settlement can take longer than settlement of the individual legs because the combo undergoes a separate review after the underlying positions are determined. The Help Center says a combo settlement typically occurs within 1 to 12 hours after the last underlying position resolves, although the timing can depend on the market and the need for official confirmation.
Key Takeaway
A blue arrow on Kalshi means that a combo leg settled at an intermediate scalar value between $0 and $1. It commonly appears after a DNP or another partial-resolution situation, and its exact value is determined by the rules of the underlying market.
The combo payout is then calculated by multiplying the scalar value by the values of the other legs. A $0.70 leg combined with two $1.00 legs produces a $0.70 payout per contract (not a full $1.00 payout, but not necessarily a total loss either).
The safest approach is to treat the blue arrow as a signal to read the underlying market’s rules. The icon tells you what kind of settlement occurred; the rules explain why it occurred and how the value was calculated.
