Polymarket Developers @PolymarketDevs Oct 5

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

Jupiter @JupiterExchange 5d

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
