Trading in the U.S. on Facebook won't start until 11:00 AM ET. 
 
 But according to Bloomberg, there are bids for the stock at 58.20 EUR in Germany, and that's $74/share! 
 
 That would be a HUGE, nearly 100% gain from the $38 where it orignally priced. 
 
 We're not sure whether there have been trades, or what that means for U.S. trading, but WOW! 
 
 If that holds in that area, we're looking at a market cap of over $200 billion.

 UPDATE: Here's a screengrab from the Deutsche Boerse showing the bid/ask, which is showing a couple lower. ||||| It's a "Beautiful Day" to be Bono. As Facebook goes public, the U2 frontman could stand to make up to $1.5 billion off the widely anticipated IPO. 
 
 UPDATE: Bono addressed rumors of his big payout with MSNBC's Andrea Mitchell. Though he did not say how much he made off the IPO, he took issue with the billion-dollar figure: 
 
 "Contrary to reports, this boy is not a billionaire or going to be richer than any Beatle - and not just in the sense of money, by the way. The Beatles are untouchable. That's just a joke. In Elevation, we invest other people's money , endowments, pension funds. We do get paid and that is a good thing, I'm blessed, but I felt rich when I was 20 years old and my wife was paying my bills. Just being in a band, I've always felt like this, I've been so blessed. I got interested in technology because I'm an artist, I'm interested in the forces that shape the world, politics, religion, the stuff we've been talking about today. Technology is huge. I wanted to learn about it. People say it's odd, 'you're a musician, why are you doing all this.' But I think it's odd if artists aren't more interested in the world around them." 
 
 CNN Money has more details on the singer's potential earnings: 
 
 Bono was one of just six founding partners of Elevation Partners. So, at best he'd get $216 million (once the original investment is subtracted). But then you have to realize that Elevation only receives 20% of the profits on its deal, with the rest going to its limited partners. So, suddenly, Bono's take is down to $43 million. 
 
 The original article continues below. 
 
 
 
 
 
 The business-savvy, Irish rocker owns 2.3 percent of the shares of Facebook through his investment group, Elevation Partners, reports NME. Elevation paid $90 million for the shares in 2009, before Facebook decided to go public earlier this year. Facebook's $100 billion IPO is expected to be the second-biggest IPO in history. 
 
 It's unknown exactly what portion of Elevation's earnings would flow to Bono, but as a co-founder of the investment firm, the handsome return may make him the richest musician on the planet, surpassing Sir Paul McCartney and his vast fortune of an estimated $1.05 billion. 
 
 In other news, U2 are reportedly working with the songwriters behind British boy band One Direction, including Swedish pop writer Carl Falk, who wrote the group's breakthrough hit, "What Makes You Beautiful." 
 
 An unnamed source told NME: "The band are back in the studio getting a feel for new material after the last album 'No Line On The Horizon'. Will.i.am had a credit on that and they are looking to explore that direction further. They have been working with Danger Mouse and RedOne. They are excited about getting to work with Carl Falk."

 Related on HuffPost: ||||| What were you doing at 9:30 a.m. Eastern? You certainly weren’t ringing the NASDAQ’s opening bell as Facebook CEO Mark Zuckerberg was doing. But what Zuck did simultaneously is perhaps even cooler. 
 
 To celebrate the once-in-a-lifetime, historic moment, Zuckerberg posted a status update like no other to Facebook. 
 
 “Mark Zuckerberg listed a company on NASDAQ. — with Chris Cox and 4 others,” reads Zuckerberg’s Friday morning update (see screenshot to the right). 
 
 The unusual status update went live right as Zuckerberg rang the opening bell, which can only mean that the social network configured the update especially for today’s special occasion. To do so, engineers used Facebook’s Open Graph API, which lets developers create custom actions, like “read a book,” “listened to a song,” or, in this case, “listed a company.” 
 
 In fact, clever Facebook engineers actually “hacked” the NASDAQ button to post the update, goes the story told by David Garcia, a senior software engineer at Facebook, on TechCrunch. 
 
 “We hooked up our hack to run at exactly the same time as Mark pushed the button to turn on the light and ring the bell. Then we attached a wire that hooks to the hack and into the headset jack of a cell phone,” Garcia said. “When the button was pressed, it sent a signal through the hack, and the phone got the signal that triggered the custom action through our Open Graph API, posting a story onto Mark’s Timeline. It worked.” 
 
 Facebook yesterday priced its shares at $38 apiece for a $104 billion valuation. The social network will raise $16 billion (up to $18.4 billion with its over-allotment option) in its long-awaited initial public offering on the NASDAQ later today. Shares are expected to begin trading around 11 a.m. Eastern today. ||||| Facebook Inc. shares slid an additional 9.6% Tuesday, as options trading began and investors placed largely negative bets on the stock’s future. 
 
 Tuesday’s decline to $28.84 puts shares of the social-networking company down 24% from their initial public offering at $38 apiece. Facebook’s debut has been one of the worst performing of any large company, according to data tracker Dealogic. 
 
 The Menlo Park, Calif., company is now valued at $79 billion, compared with $104 billion at the time of its IPO. Chief Executive and co-founder Mark Zuckerberg has seen the value of his stake sliced to about $14.5 billion from $19.1 billion. 
 
 Since Facebook eked out a small gain on its first day of trading May 18 with the support of its lead IPO banker Morgan Stanley, the stock has slid amid both fallout from technical glitches as well as questions about whether the offering’s size and price together overwhelmed demand. Facebook has seen big drops in three of its six full days of trading. 
 
 The lingering concerns about the company’s shares were aggravated by the options-market debut, which allows investors to bet on the future of the stock with less money at risk. Facebook options kicked off trading with a burst of activity, as traders bet the beaten-down shares have further to fall. That is a sharp contrast to the excitement leading up to Facebook’s IPO, when many investors clamored to get a piece of the company. 
 
 “It’s pretty stunning to watch,” said Keith Bliss, a New York Stock Exchange floor trader and senior vice president at Cuttone & Co. “I haven’t seen a turnaround in sentiment this severe in 15 years, and certainly not for an IPO.” 
 
 Facebook, in a so-called quiet period following its offering, has declined to comment on the share-price decline. 
 
 Facebook’s latest stumble came in spite of a broader market rally. The Dow Jones Industrial Average rose 1% and the Nasdaq Composite Index gained 1.2%, as technology stocks led much of the day’s advance. 
 
 An option is a contract that allows investors to bet on a stock’s direction, and as is typical for IPOs, options trading for Facebook began about a week after its stock-market debut. 
 
 In order to begin listing options on a company, exchanges must first propose the terms of the options and file for approval with Options Clearing Corp., an industry clearinghouse. While it first approved the listing of options with prices as low as $16, one exchange later applied to change that low to $1. When one exchange enacted the change, the others followed. 
 
 The trading in Facebook options Tuesday by investors big and small was intense and largely bearish. Trading set a record for any option making its debut, according to data provider Trade Alert, with nearly 365,000 contracts changing hands. Among company options, only Apple Inc.’s were more active on Tuesday. 
 
 The largest option trades bet that Facebook shares would continue to fall. These trades used options known as “puts” to wager on Facebook slipping to $25 a share by mid-July. Puts are contracts that give the buyer the right to sell stock later for a set price. These particular bets maximize their profit if the stock trades at $25. 
 
 A $25 price is considerably lower than where analysts are valuing the stock. Many analysts covering the company say the stock is worth more than its current price, with firms that recommend clients buy the stock putting price estimates on Facebook at between $40 and $48 a share. Some firms with “sell” ratings on the stock earlier had advised a $30 price target. 
 
 While bearish bets drew the most options activity, some traders were bullish, wagering shares would reach $65 by January 2014. 
 
 A declining share price doesn’t necessarily hurt a company financially—Facebook still had one of the biggest U.S. IPOs ever, raising $16 billion. But in general, corporate directors and executives pay close attention to a company’s shares as a real-time measure of performance. Shares can also be important for recruiting and retaining employees, and can serve as a currency for acquisitions. 
 
 So-called momentum stock traders were watching the opening of the options trading in the company with particular attention, said Cuttone & Co.’s Mr. Bliss. When trading took off in the first half-hour, with most wagers bearish, the momentum traders who try to capitalize on shifts in a share price’s direction sprung into action, he said. 
 
 “The momentum guys…make a decision about which way this stock is going, and then they long or short it and it becomes a self-fulfilling prophecy,” he said. 
 
 Even before Tuesday, traders were able to “short” shares of Facebook, as a way to express a bearish bet, essentially selling borrowed shares in hopes of being able to buy them later at a lower price. Around 2:16 p.m. Tuesday, Facebook shares were down 10%, triggering a so-called circuit breaker that limited short selling for the rest of the session and through the close of trading Wednesday. 
 
 However, options give investors an easily accessible and, some argue, less risky way to bet on a stock’s gyrations. 
 
 By buying a bearish option on Facebook rather than shorting the stock, for instance, investors can reap the gains of declines in Facebook, while capping any potential losses were shares to rebound. In contrast, if an investor were to short Facebook, any sharp rise in the stock could leave a bearish investor with hefty losses. 
 
 A significant portion of the activity in Facebook options Tuesday came in small batches of contracts, suggesting interest from small investors, according to Jeff Shaw, head of trading at Timber Hill, the market-making unit of Interactive Brokers. “There is a fairly large individual presence in this activity,” he said. Market makers are professionals who take the other side of investors’ trades. 
 
 One person making bearish bets Tuesday was Janet Tavakoli, who runs a structured-finance consultancy. 
 
 She decided to bet against the shares with her own money, she said, and purchased 100 contracts in September $25 puts, dated to after the expiration of the first wave of so-called lockups that restrict sales by early investors. 
 
 She is essentially wagering the stock will go below that price by then. 
 
 “I thought, given that the puts are available, let me make the point that I think this is full of hot air,” she said, pointing to Facebook’s mobile strategy and valuation relative to earnings as what she sees as problems for the shares. 
 
 Some people were willing to take the other side of those types of trades. Douglas Estadt, founder of Pennwall Capital, with about $10 million under management, said he had sold 65 contracts in June $26 puts and June $25 puts as a means of collecting income while also offering a good entry point to buy the stock. 
 
 Selling the contracts, which cover 6,500 shares of Facebook, allowed Mr. Estadt to collect between 20 cents and 35 cents a share. If Facebook’s stock stays above the $26 level, Mr. Estadt gets to keep those proceeds. If the stock falls, Mr. Estadt could be obligated to buy Facebook shares at the $26 and $25 level. 
 
 “Either way, I’m doing pretty well. Either I collect the premium or own the shares very cheaply,” Mr. Estadt said. “I’d be happy to own Facebook at these prices. Facebook is profitable, and I think it will grow.”

 The lawsuit, filed today in a Federal Court in San Jose, California, combines 21 separate cases across the US and could have far-reaching ramifications for the social network at a critical time. 
 
 Facebook priced its flotation at $38 a share last night, valuing the company founded by 28-year old Mark Zuckerberg at $104bn. It will begin trading at 4pm today, shortly after the opening of the Nasdaq stock exchange in New York. 
 
 As a public company, Facebook will be expected to grow its advertising revenues very rapidly, putting it under considerable pressure to collect more and more user data to help it target its ads. 
 
 The company made 85pc of its $3.71bn of revenues from advertising last year but that figure appears paltry in the context of Facebook’s extraordinary reach. The social network has 900m users worldwide. 
 
 Many analysts and experts are sceptical about the effectiveness of paid-for advertising on Facebook. 
 
 Sir Martin Sorrell, chief executive of the world’s biggest advertising group, WPP, has said he has “fundamental” doubts over whether Facebook provides the right “context” for ads, and earlier this week General Motors, the US car manufacturer, said it would stop buying ads on the social network. 
 
 However, Facebook argues that its ability to carefully target its adverts makes them increases their value. If, for example, a female user changes her relationship status to “engaged”, Facebook is able to tap into that and ensure lots of adverts for wedding dresses and other bridal services appear on her Facebook page. 
 
 If the claimants are successful in their $15bn case against Facebook, they could prevent Facebook from collecting so much data and severely impede its ability to grow advertising revenues. 
 
 “This is not just a damages action, but a groundbreaking digital-privacy rights case that could have wide and significant legal and business implications,” said David Straite, a partner at Stewarts Law, the US law firm that is representing the companies in the class-action lawsuit.
– By the time you read this, Facebook shares will likely have begun trading (or not). But the hoopla around the IPO was slightly dampened today, thanks to a mammoth class-action privacy lawsuit filed against it. The case combines 21 separate suits accusing Facebook of tracking users even when they weren't logged in, the Telegraph reports. They're looking for $15 billion—almost enough to wipe out the $16 billion Facebook stands to take in today. In other IPO news: Mark Zuckerberg rang the opening bell this morning, in a remote ceremony from Facebook's Menlo Park campus, VentureBeat reports. The best part? The button he pushed was rigged so that ringing the bell would publish a status update on Zuckerberg's timeline: "Mark Zuckerberg listed a company on NASDAQ. — with Chris Cox and 4 others." How high will Facebook go? Well according to Joe Weisenthal of Business Insider, bids in Germany have hit $74 per share—a massive gain on the $38-per-share they've been priced at. One man watching that price with great interest? Bono. The Huffington Post points out that the U2 frontman owns 2.3% of Facebook, and may, after today, be the richest musician in the world.
