After 11 trading days and six rounds of action, the winner of TheStreet's Market Bracket Challenge has been decided, and it's none other than Mark Zuckerberg's social media giant, Facebook (FB - Get Report) .

An Action Alerts PLUS portfolio holding and a No. 11 seed to start the tournament, Facebook squeaked by Tim Cook's tech giant and fellow AAP holding Apple (AAPL - Get Report) in a one-day matchup on Monday. Apple, a No. 5 seed heading into the tournament, finished the day down about 0.01%, while Facebook finished the day up 0.25%.

The two battled furiously over the course of our 11-day challenge and made it past some pretty stiff competition, including the likes of freshly public Snap (SNAP - Get Report) , home improvement retailer Home Depot (HD - Get Report) , Nike (NKE - Get Report) and everyone's favorite gene sequencing company, Illumina (ILMN - Get Report) . Facebook is up 23% year to date, while Apple is up about 25%.

But on Monday it was a "what have you done for me lately" story, and it seems that Facebook has done more to prove its worth to investors lately. In addition to just plain eating Snap's lunch over the past few weeks (announcing copycat features such as stories and filters to its various products) the company also had some news trickle out from its upcoming investor conference. A report from TechCrunch Monday surfaced that Facebook is expected to introduce Bots that would work within Facebook Messenger's group chats. The company did not confirm or deny the reports, which suggested the new feature could be unveiled at Facebook's annual conference beginning April 18.

Apple meanwhile, could have some bigger catalysts coming down the pike, but news today was not enough to spur gains to propel it past Facebook.

According to a report from Recode, Apple is negotiating with Time Warner's (TWX) HBO, as well as Lions Gate's (LGF.A - Get Report) Starz and CBS's (CBS - Get Report) Showtime, to sell their premium cable channels as a bundle. The deal would get Apple further into the battle over streaming content. The report, however, said Apple likely would stick to premium streaming options as the basic networks have not been amicable to handing over content to Tim Cook's company.

So while it was a pretty boring day overall for two of the most influential companies on the planet, the lead-up to our championship tilt was anything but. Let's take a look at the highlights from Apple and Facebook's matchups throughout the tournament:

Round 5 (Round of 4): Apple Kicks Nike to the Curb, Facebook Chugs by Illumina (March 30 & 31)

It was never really a contest, to be honest. After taking a bit of a hit Thursday, Beaverton, Ore., footwear maker Nike continued its decline on Friday. Apple, meanwhile managed to stave off a big dip over the two days, finishing down less than 1% over Thursday and Friday. Maybe it was just a lack of real catalysts for Nike, or maybe it was the fact that Under Armour (UA - Get Report) recently released a high-end sneaker (priced at $300 per pair) that could challenge Phil Knight's apparel powerhouse.

On the Apple front, analysts seemed bullish on the Cupertino, Calif., tech company, and that was enough to keep its stock from dipping too much and putting it out of the running. Canaccord Genuity analyst Mike Walkley on Friday reiterated his buy rating on Apple's stock and hiked his price target to $165 from $154, saying the company has "little to fear" from Samsung's new Galaxy S8. And then there was that talk earlier in the week that the company could be worth as much as $200 per share in the not-so-distant future.

Illumina Can't Keep Its Winning Sequence Going

Oh, Illumina. You plucky, $25.1 billion in market cap, gene sequencing company, you. The South Carolina of TheStreet's Market Bracket Challenge, Illumina had its title hopes dashed as the company posted a 0.8% dip over Thursday and Friday. Illumina couldn't muster the gains it needed to topple the House that Zuck Built, which only ticked down about quarter of a percentage point.

Zuckerberg's social media behemoth posted a slight loss over the past two trading days, enough to eke out a victory and punch its ticket to the title matchup. Facebook investors shrugged off news that Palmer Luckey, co-founder of Facebook's virtual reality company, Oculus, would be leaving the company. The dominant themes for Facebook over the past week or so (and going forward for that matter) continued to be how it planned to eat Snap's lunch and how digital ads and marketing will continue to proliferate on the internet. Investors shrugged off news of a congressional ruling that could make it easier for cable operators and telecoms to sell patrons' personal data for profit.

Round 4 (Round of 8) : Apple Gives CBS a Black Eye, Snap's Epic Run Dashed (March 28 & 29)

The house that Jobs built headed into the tournament's semifinal round after tackling CBS, the host network of that other tournament going on right now, in the Round of 8. It's been all quiet in midtown Manhattan for CBS, as there really hasn't been a trading catalyst for the company of late. Meanwhile, Apple was on a tear after one analyst recently suggested the company could be worth $200 per share in the not-so-distant future, and critics already were saying that the Cupertino, Calif., tech company shouldn't be worried about the new competition from Samsung.

Facebook's Copycat Tactics Mute Snap's Epic Run

Though the matchup in TheStreet's Challenge was Snap vs. Nike, all eyes over the Round of 8 were on Snap's prospective bout with Facebook. Snap shares took a dive on March 28 and didn't recover enough in the second half after Mark Zuckerberg's social media empire launched its latest attack on the fledgling, self-described camera company.

Round 3 (Round of 16): Micron Can't Fabricate a W (March 24 & 27)

Micron (MU - Get Report)  fought tooth and nail, but it couldn't score a win over the world's largest company by market cap. Apple moved on to take on CBS in the regional finals. Micron, the last remaining No. 1 seed in TheStreet's Market Bracket Challenge, had been on an epic run-up until the seeding of the tournament. The run, which helped it secure the third overall seed in TheStreet's bracket, proved unsustainable. "After Micron's previous earnings report, back on Dec. 22, the stock consolidated after the 12.65% gain for three weeks," TheStreet's Gary Morrow said in a March 27 post. "At Friday's peak Micron had stretched its gain since the December 22 report to 40%. Another post-earnings pullback similar the last one now looks very likely."

Round 2 (Round of 32):Apple Slices by Time Warner, Barely (March 22 & 23)

Fan favorite Apple narrowly escaped the jaws of defeat, posting a slight gain over March 22 and 23, while its foe, Time Warner, posted a slight loss. It had been a busy week for the House that Jobs built, as the company on March 22 acquired a popular automation app, Workflow, for an undisclosed sum and made it free on the App Store. Meanwhile, Merrill Lynch analysts expected Asian suppliers to ship 100 million iPhone 8s when the phone is released later this year.
