Next Google Gemini Pro Model released by 2026?

Platform comparison

Market context

Google has still not put Gemini 3.5 Pro into broad public release, even after shipping cheaper Gemini variants and saying the flagship model is being tested with partners and should arrive “soon”. Reuters reported on 21 July that Google launched lighter Gemini models but gave no firm date for the Pro tier, which keeps the market anchored to launch timing rather than model quality. [12]

The pattern here is delayed but not abandoned: Google moved Gemini 3.1 Pro into preview across the app, API, Vertex AI, Gemini Enterprise and NotebookLM, showing it will often stage access before any wider rollout. Its model pages also show long-lived product lines and staggered transitions, while older Pro models remain supported well after newer releases, so a late-cycle public debut would still fit Google’s usual cadence. [9][1][3]

For traders, the key catalysts are any Google blog post, Gemini release note or API changelog entry that upgrades a Pro model from preview to general availability, plus any scheduled product event where the company could bundle a launch with broader Gemini announcements. A fresh confirmation from Google staff would matter more than speculation, because the market only pays out if the next Pro model is made available to the general public, not merely tested with partners or rolled out in limited preview.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
