Who owns the Elder Wand in "Fantastic Beasts And Where To Find Them"?

Question

In Fantastic Beasts And Where To Find Them, when Tina disarms Graves,

(Grindelwald)

does she then become the owner of the Elder Wand?

Answer 1

Grindelwald owns, as in physically possesses, the Elder Wand.

In the promotional picture for the next movie in the series, Fantastic Beasts: The Crimes of Grindelwald, Grindelwald is seen holding the Elder Wand.

This doesn’t show whether he’s the master of the Elder Wand, but it shows that he has the Elder Wand. That he has it is referenced on Pottermore, in one of their pieces giving information on the next movie.

Grindelwald has the Elder Wand
In this new photo, Grindelwald is seen holding the familiar, textured wand we recognise from the Harry Potter films. From the books, we know that Grindelwald stole the most powerful wand in the wizarding world from the wandmaker Gregorovitch quite early on in his reign of terror.

He’s also seen holding it in the second trailer released for Fantastic Beasts: The Crimes of Grindelwald, which is referenced in a news release on Pottermore.

Grindelwald has the Elder Wand

Well, that settles that. The Elder Wand, one of the three Deathly Hallows, is definitely in Grindelwald’s possession during the events of this movie. There is simply no mistaking its recognisable berry-esque carvings that we remember oh-so-well from the Harry Potter films.

As far as we know, the next person to take the wand was Dumbledore after their famous 1945 duel. The Crimes of Grindelwald is set in the 1920s so... blimey, does that mean Grindelwald owns the wand for at least two decades? That doesn’t sound like a fun two decades, if so.

So, at the time of Fantastic Beasts and Where to Find Them, Grindelwald physically possessed the Elder Wand and seems to be using it as his own, though we don’t know yet if he’s its true master.

It’s not confirmed yet, but Tina probably isn’t the Elder Wand’s master.

It’s unlikely that Tina would have changed the Elder Wand’s mastery, since she didn’t “win” over Grindelwald. Grindelwald dropped the wand he had been using, and Tina summoned it away. She neither Disarmed him using Expelliarmus, nor did she wrestle the wand from his hand.

“With a sense that he’s been holding this one back, he slashes it through the air: out flies a crackling rope of supernatural light that wraps itself around GRAVES like a whip. GRAVES tries to hold it off as it tightens but staggers, struggles and falls to his knees, dropping his wand.

TINA
Accio.”

Grindelwald likely would have had mastered the Elder Wand himself before his encounter with Newt and Tina, so if he did, the mastery of the wand would likely be with either him or Newt. To get the Elder Wand, Grindelwald had broken in, Stunned Gregorovitch, and stole the wand - Stunning him would likely count as defeating him.

Answer 2

I'm actually not sure why there is so much debate on this subject. It was quite obvious to me whats happened so far if you understand that JK will very much reuse old plot devices in her work because... it’s easy and very much in line with her writing style:

1. Grindlewald was the master of the Elder Wand in FB1 since he's undefeated upto this point

2. Newt defeats Grindlewald at the end of FB1 (he clearly restrains him with his spell) and is now the master of the wand (remember tina only summoned the wand after newt won so she's irrelevant to the discussion)

3. Newt is the only one actually able to defend against the protego diabolical spell in FB2 (watch closely, it incinerates the Aurors while Newt has no problem deflecting it out of his way) because as master of the Elder Wand the spell wont hurt him. Thesius only deflects the fire because a) he's alongside Newt who’s actually doing the work (unless I'm mistaken they're side by side for most of the scene) or b) because leta's 'love' saves him when he's briefly separated from Newt (we do remember the whole love thing right? why else would leta's death change the fire like that and why would she mention "doing it to save him")

aaaaand thats where we are so far. Newt is pretty obviously the current master based on the above observations and we just have to wait and see what happens next.

The simplest solution would be grindlewald defeating newt in a later movie so hes back in charge of it for the 'Dumbleduel'

However I suspect JK is going to go for a rehash of her 'who's actually the master' plot device from harry potter - ie: Dumbledore will disarm Newt at some point and will be the Elder Wand master (unbeknownst to Grindlewald) so he will have the edge in the 'Dumbleduel' allowing him to beat Grindlewald. This actually makes sence since Dumbledore will use the same strategy to help Harry beat Voldemort decades later (Dude had to learn the strategy from somewhere, why not by using it to take down Grindelwald first).

Answer 3

We don't know

Rowling has said in an interview that the identity of the current owner would be a spoiler, so we can probably assume Grindelwald doesn't have it during the events of the first film (him having it was already shown in the books ave thus wouldn't constitute a spoiler).

What happened to the Elder wand? Where is it? The elusive Elder wand.

JK Rowling: Where is it right now?

Yeah.

JK Rowling: I can't tell you, but you will find out in movie two

As shown by the promotional material cited in Bellatrix's answer, Grindelwald likely acquires it at some point during the second movie, but we really don't know who has it before that point.

Answer 4

The person holding the Elder Wand at the end of the Crimes of Grindelwald trailer is holding it in their left hand. Grindelwald appears to always hold it in his right. Also, you’ll notice the carriage is still being pursued by Aurors in the background, bottom left.
