Introducing Polymarket Protocol V2, a new smart-contract foundation built for prediction markets.
To give developers and market makers time to integrate, we’re running canary markets October 5–30, with new markets tentatively switching on November 2.
With this release, we’re also introducing Data API v2, a new Rust service powered by our in-house on-chain indexer
Start with the migration docs here: poly.market/v2-migration

Predictions just got bigger.
Combos are live on Jupiter Predict, powered by @Polymarket
Stack multiple picks into one trade and go for a bigger payout.
How it works:
→ Pick your outcomes across sports and esports
→ Add them to one Combo
→ Check your potential payout and confirm
The more picks you add, the higher the payout. But every pick has to hit. Miss one and the whole Combo is lost.
Supports moneyline, spread and total markets, with more categories coming soon.
All in or nothing 👇

Breaking Changes: Effective November 12, 2026 at 00:00 UTC
As part of ongoing security and infrastructure hardening, the following changes will take effect on Thursday, November 12 at 00:00 UTC. Please review and confirm whether any of them impact your integration.
1. Relayer: Restricted to Standard Polymarket Calls
The relayer will only process standard Polymarket contract calls. Transfers are unaffected. Requests involving custom contracts or bespoke calls (e.g. leverage or lending flows) will no longer be supported.
2. Relayer: Hardcoded Relayer EOA No Longer Supported
Integrations that hardcode the relayer EOA will stop working. Please call /relay-payload for each transaction instead.
3. Gamma API: Gzip Required for Large Responses
Requests to /events and /events/keyset with limit greater than 50 must include the Accept-Encoding: gzip header. Requests without it will return HTTP 406. Most HTTP libraries send this header by default
RTDS price feeds shut down Nov 30, 00:00 UTC
All RTDS price topics (crypto, Chainlink, TWAP and equity) are moving to PolyBolt. Please migrate before then.
Migration guide: docs.polymarket.com/migrate/…
The activity topic is not affected
The Protocol V2 release has moved from November 2 to November 9 to keep midterms week clear.
The final schedule and rollout plan will be shared in the next few days, including exact timings and the order in which markets will migrate.
No action is needed in the meantime.

Polymarket Protocol V2 canary markets are now live across weather markets. Find them using ?version=v2, with slugs following polyv2-central-park-{question}-{YYYY-MM-DD}.
These markets are for testing only, with limited liquidity and no production-level support guarantees.
We're targeting November 2 for net-new markets to launch on Protocol V2.

We've deprecated our legacy SDKs, including the CLOB and relayer clients (TypeScript and Python), in favor of the unified SDK.
The deprecated packages will keep working but will no longer receive updates. This is not a breaking change, so existing integrations, including those migrating to Polymarket V2, can continue using them.
We recommend moving to the unified SDK to get the latest features and fixes.
