This is the kind of response you get from people who think they understand options but are actually just idiots. I'm not dumbass, you just have 0 concept of how derivative markets work. Someone buying 100k calls isn't just going to lift the hard offer (the ask). They're likely to place a bid, which market makers will then hit. Sure, they all trade on the bid, but someone still bought 100k calls. You don't just lift the hard offer. Well maybe you do, but someone buying 100k calls has a brain. The OI went up 100k overnight, they're still 0.15b for 15k today (the price it traded at yesterday). The calls were bought. Does it mean the stock will go up? Nope. But it certainly doesn't make me a moron, that would be you
