August 24, 2026

Banned accounts are now fully frozen

fix

Suspended accounts could previously still have their existing resting orders matched by other traders, and in some cases could still place orders on the main markets. A suspension now takes full effect immediately: banned accounts cannot place orders anywhere, their resting orders can no longer be filled, and those orders are cancelled automatically.

August 22, 2026

Market listing, detail, and creation endpoints restored

fix
api

A deployment issue caused market listing, market detail, and market creation requests (on the site and via GET/POST /api/v1/markets) to fail with server errors. The missing server dependency is now packaged correctly and these endpoints work again. No markets or data were affected.

August 22, 2026

Ranked-choice election markets

feature

Election markets for ranked-choice races, including Alaska and Maine, can now be created and will settle automatically once final results are published.

August 22, 2026

Verbatim market titles for organization API keys

api

Market creation via the API now accepts a preserveSubmittedTitle option for organization-bound API keys. When set, the submitted title is stored exactly as provided instead of being replaced with a server-generated title. It applies to single-contract markets only; composite submissions are rejected.

August 22, 2026

Header and small-screen layout fixes

fix

The organization header no longer overlaps the balance chip with navigation links at common desktop widths. On tablet-sized screens the account menu opens reliably, wide tab bars can be scrolled instead of being cut off, and tournament cards keep their details on one tidy line.

August 22, 2026

Fusion party tickets

improvement

Election markets now handle candidates who run on multiple party lines at once, as in New York. A party market pays out when the winning candidate is affiliated with that party, even as part of a fusion ticket.

August 21, 2026

Two-sided quoting and selling without shares

feature
api

You can now quote both sides of a market at once and sell shares you do not hold — an unbacked sell is placed as the equivalent buy of the opposite side, and buying against your existing position pays out 1 credit for every matched YES/NO pair on the spot. Orders that would trade against your own resting orders never self-match: they fill other traders first and the crossing remainder is cancelled automatically. API responses now report the canonical order that was placed; non-idempotency placement conflicts now return 400 or 403, while 409 is reserved for idempotency conditions and requests still in flight.

August 21, 2026

Organization header logo contrast and scaling

improvement

Organization logos now appear white over hero imagery and return to full color on the light header. Wide logos also scale correctly on mobile without crowding the navigation.

August 21, 2026

Free market creation on organization sites

improvement
api

Creating markets on organization sites is now completely free — no creation fee, no multi-outcome surcharge, and video generation is included at no cost. Pricing rows, balance requirements, and paid add-ons that don't apply to organization sites (Super Signal, liquidity boost, anonymous mode) no longer appear in the market builder. Organization-bound API keys also create markets free of charge; requests that set superSignal or a positive liquidityAmount are now rejected with a validation error.

August 19, 2026

Organization-scoped API reads

api

Organization-bound API keys now resolve every account, portfolio, and leaderboard read to their default tournament instead of the public global context, matching how orders and market data already behave. Tournament-scoped fills and portfolio history endpoints were added, and explicit tournament filters are now validated — unknown or inaccessible tournaments return 404/403 instead of empty results. Pagination cursors issued before this release should be discarded; restart any in-flight pagination without a cursor.
