Spider-Man movies make their way into the MCU. And they all seem to be gunning for Spider-Man.
In a Venom 2 post-credit scene, Venom appears to enter the MCU; however, that might not be what's truly happening. Brock and Venom watch TV during the scene, but they become shocked when their surroundings instantly change. Suddenly, their room is noticeably nicer, and the J. Jonah Jameson's (J.K. Simmons) report about Spider-Man's identity is playing on the TV. The appearance of Holland's Spider-Man seems like confirmation that Venom is now in the MCU, and Doctor Strange's failed No Way Home spell could be why. But there's an alternate explanation as well.
Though it seems like Venom is in the MCU, the Multiverse complicates things. Because of the Multiverse, there are endless possibilities and infinite timelines. Due to these possibilities, Venom could've entered another timeline, but that doesn't mean he's in the main MCU. After all, while the footage playing on the screen looks like Jameson's footage from Far From Home, it's slightly different. In the footage from Venom 2, Tom Holland's Peter Parker is wearing his Spider-Man suit but has his mask off. However, in the Far From Home after-credits scene, he appears while wearing his mask. It's a small change, but it leaves enough leeway for Marvel to take the story in a different direction.
When it comes to Marvel, fans should be skeptical. In X-Men movies ed the MCU. However, the WandaVision ending revealed that wasn't the case. Peters' character was simply a random guy named Ralph Bohner, and he was enchanted to pretend he was Quicksilver. Additionally, Marvel regularly fools fans with its trailers, showing fake or doctored footage to throw viewers off the actual plot. If Marvel is tricking fans with its Venom: Let There Be Carnage scene, it wouldn't be the first time.
