The short version
MODE 2 OF 2
What the primary record establishes
Kalshi’s documentation, updated 20 August 2026, describes dollar-price strings with up to four decimal places and contract-quantity strings with up to two. Integer-cent fields cannot represent sub-cent prices. Kalshi — Fixed-Point Representation, updated 20 August 2026 ↗
What the distinction changes
Representation and permission are separate. A system can parse “0.1234” accurately while that price remains outside a particular market’s grid. Rounding every input to whole cents can instead discard a valid finer price.
What to check before drawing a conclusion
WFN would preserve the original strings, apply decimal arithmetic and validate against the market’s current ranges. These are implementation review points; the article supplies no live market tick size or claim that one grid applies everywhere.

The linked source supports the documented record; WFN interpretation and illustrative examples are separate.
A price string can carry four decimal places without making every such price valid. The market’s price_ranges define the permitted steps.

The documentation identifies price_ranges, an array of start, end and step bands, as the source of valid prices for each market. It recommends consuming those ranges dynamically rather than keying pricing logic to the price_level_structure label. Kalshi — Fixed-Point Representation, updated 20 August 2026 ↗

What the distinction changes
Representation and permission are separate. A system can parse “0.1234” accurately while that price remains outside a particular market’s grid. Rounding every input to whole cents can instead discard a valid finer price.
Quantity precision needs independent treatment. An order or fill expressed as a fractional contract should not silently become an integer. The resulting notional changes even when the price is copied correctly.

What to check before drawing a conclusion
WFN would preserve the original strings, apply decimal arithmetic and validate against the market’s current ranges. These are implementation review points; the article supplies no live market tick size or claim that one grid applies everywhere.
Price precision also does not describe a fee schedule or guarantee an execution. Confirm the relevant contract, current grid and fee rules before turning a technically valid price into an economic comparison.
