No. You're incentivized to build a market prosition on prediction markets, or sell your information to somebody who can. (E.g. if a lab has a replication proof it might partner with a trading firm to maximize their profit.) But there's definitely no incentive to do it "for as long as possible". E.g. once the trader gets into a favorable position, they are incentivized to reveal their information ASAP to be able to take profit.
