Market context
Brandon Aiyuk is expected to leave the San Francisco 49ers and join a new NFL team before the 2026 campaign, with the 49ers having voided all guarantees in his contract and general manager John Lynch openly seeking a trade[1][3]. Despite remaining on the roster at the time of writing, the 28-year-old wide receiver is widely anticipated to depart, as the situation has not worked itself out in San Francisco and Lynch has stated the team is available for calls[1][3].
Historical precedents for high-profile receivers leaving teams mid-contract due to financial restructuring suggest a 21% probability of a specific listed team is plausible, though "Other" outcomes remain common when trades fail or players retire[2][4]. Comparable cases, such as Deebo Samuel’s move to Washington, show that former teammates can reunite, yet Aiyuk’s knee injury and the 49ers’ cap constraints create significant uncertainty about whether he will sign anywhere by August 2026[2][4].
Traders should monitor official signing announcements before August 31, 2026, and watch for updates on Washington Commanders’ interest, as Aiyuk has expressed desire to reunite with Jayden Daniels[2]. Key dependencies include the Commanders’ cap space, the Titans’ projected highest cap availability, and whether the Ravens pursue an outside receiver to fill a years-long offensive gap[2]. Any delay in a trade or release could push the resolution to "Other", especially if Aiyuk does not secure a contract by the deadline[3][8].
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Sport Prediction, which mirrors the Polymarket order book directly.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
