Because those should earn two very different amounts of trust.
Yes, it does. “For now” has no definite endpoint and thus states that the mission targets indefinite control of territory. (“Until <clear objective endpoint>” is not, on the surface, indefinite, though if the endpoint is a fixed point in time but one of conditions that may or may not ever be met, it might still be indefinite if the criteria is temporal definition, but “for now” is indefinite by any standard.)
It does not target permanent control, but permanent is distinct from indefinite.
I also don’t find “for now” to be clearly indefinite, but I agree it depends on which of multiple definitions of “indefinite” you use, and it does fit some definitions. (Similarly, “permanent” also has multiple definitions, some of which overlap with some meanings of “indefinite”.)
Am I running if I say "I'm running now" while I sit in my chair?
I don't care if the almighty comes down, waves their tentacle and says "let there be light" - if it's still dark after their pronouncement, then anyone who bet a light would appear should lose the bet.
Trump's declaration that he is taking over Venezuela fits pretty comfortably within this category.
In your terms, a light did appear. You're right that the light is not directly connected to the utterance. But since the argument above that there was no invasion is premised on a lack of intent to invade rather than on the invasion not having happened, the utterance disproves that.
Emphasis on "intended to". Speech does count as intention, even if you haven't successfully achieved whatever you say you're doing. If the President says the US intends to control Venezuela, then the Polymarket statement is true.
All the Israel markets have clearly established this interpretation. Israel has done many raids intended to influence foreign governments, but not to control territory, and those markets didn't count as invasion.
There are other markets if you wanted to speculate on regime change or any kind of military action, but "invade" has a specific meaning.
This happens every single market and it's free money for people that understand the rules.
Edit: I guess "raiding" as you say, but that's a tactic used during a war, and apparently we aren't at war. If Israel had announced after a raid that their intent was to control the target country, then I would say their raid was actually an invasion.
My favourite invasion market was the Syria one, where Israel took the peak of a mountain on the border of the Golan Heights and the rest of Syria, and there was a huge dispute over whether the peak itself counted as Syria proper.

"I'm running now" doesn't make you jog if you're sitting down, but it certainly kicks off a campaign if you were considering elected office.
JL Austin called these sort of statements "performative utterances" and there's a lot of linguistic debate about them. Nevertheless, "I declare war", uttered by someone with the power to do so, is pretty unambiguously an example of one.
(A relevant point is that people were still betting on Trump winning the 2020 election even after the results were out in part because it was possible that Polymarket would side with his opinion, but it's probably for the best they didn't...)
Boots on the ground, baby.
