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
Read more about both in the blog below:
Starting December 14, we’re deprecating three CLOB API behaviors to simplify order and trade queries:
- associate_trades will no longer be supported on order and trade responses
- GET /data/orders will require market when filtering by asset_id
- GET /orders and GET /v1/trade/open-orders will no longer accept asset_id or token_id filters

Polymarket DeFi Combos from Builders 📈
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 👇

New security feature: Withdrawal address allowlisting
You can now lock withdrawals from your deposit wallet to addresses you’ve approved. Adding a new address requires email verification and a 48-hour time lock, and you can cancel it from the email if it wasn’t you. That means even if someone gets into your session or you sign a bad transaction, they can’t drain funds or transfer your positions to an address you don’t control. I highly recommend enabling it if you are on the latest wallet version.
Turn it on in Settings → Account. Passkey support is coming soon to strengthen security further.
For non-deposit wallet users, we are developing a migration tool to help you move everything to the new wallet type. If you don't want to wait, you can open a new account to access this feature immediately.
We are also working on adding more advanced built-in security protection, without requiring you to enable anything on your deposit wallet - will also be live soon.

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

Today we're excited to share what's new in Whitewallet. We introduce a new feature that gives you a new way to put your read on the world to the test.
Introducing Event Markets, powered by @Polymarket
Got an opinion on how something's going to play out? Now you can express your view.
Event Markets let you explore the outcomes of real-world events - crypto, finance, culture and more - directly through the Whitewallet interface. Browse open markets, take a position, and see how it plays out. Prices move in real time as other participants weigh in, so you're always tapping into live crowd consensus, not a static house number.
Event Markets run on @Polymarket, a third-party, non-custodial protocol. Your positions stay on-chain in your wallet - and like any market, you can win, you can lose, and outcomes aren't guaranteed. Availability varies by region.
Available now in the Whitewallet app.
*Feature availability is subject to regional restrictions. Not available to users in the US, UK, EU, or other restricted jurisdictions. Powered independently by Polymarket.

Yesterday, a 3rd-party performance script on polymarket.com was compromised by its vendor's attacker & swapped for one built to target our users. For a small window of time, it used open sessions to sell positions and move funds. The vendor has publicly confirmed the breach..
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.
