In the ever increasing furry over Apple’s upcoming tablet device, many are looking to market indicators for a hint of what’s to come. Now there are two markets that indicate “iPad” as the upcoming tablet name: betting websites and domain name registrations.

Betting website Paddy Power has changed the odds in the Apple tablet naming competition. Yesterday “iPad” had a strong lead over “iSlate” with odds 1/3 and 2/1 respectively. Last night, however, “iSlate” odds improved dramatically from 2/1 to 5/4. While the 1/3 odds for “iPad” remained the same, these changes indicate that the recent “iPad” trademarks may not be as convincing as they were earlier in the week when the news first hit.

Meanwhile, dark horse “iBook” has finally joined the race today jumping in at 4th place with 12/1 odds, just behind “iTablet” which has stayed steady at 10/1 odds since Saturday.

While betters may be growing more indecisive, domain investors and speculators are pointing to “iPad” as the tablet name. In analytics I ran earlier this morning on the number of .COM domains registered over the past 48 hours, the keyword “iPad” increased by 93 domains, “iSlate” increased by 76, “iTablet” scored 14, and “iBook” grabbed fourth place with just 12 domain registrations.

Sedo had a good week with a nice six-digit sale, while total sales dropped to $778,261 and the median dropping to $2122. The total number of domains sold (over $700) increased to 182, which indicates that volume is consistent.

The largest sales this week include “website.de” selling for $143,136, “bookkeepers.com” selling for $34,000, “juegos-gratis.com” (“free games” in Spanish) for $26,179, and a great two letter .ORG “ch.org” sold for a reasonable $21,775.

In the last month many trademark filings and a whois record have come to light that point to possible names of Apple’s forthcoming tablet computer. The two names with the most trademarks are “iSlate” and “iPad” with “iTablet” being predicted by at least one Apple blog. While the news, blog, and IP worlds still haven’t decided on a name, the betting world has reached consensus.

European betting website Paddy Power has been running odds on potential Apple tablet names and initially indicated “iSlate” would be the most likely name. Last week they were paying 4/5–less than even money–for “iSlate” and 7/5 odds for “iPad.” The flurry of international trademark activity last week has made big changes to the odds. On Saturday the odds for “iSlate” and “iPad” reversed, giving “iPad” the lead of 1/5 odds before settling down at 1/3 earlier today with “iSlate” running as high as 9/4 before dropping slightly to 2/1.

With odds for the Colts winning the Superbowl at around 1/2, the 1/3 odds for “iPad” make it sound like a sure bet.

Sedo announced sales figures for last week when they sold 174 domains for $860,305. The total was down significantly from the previous week by almost $1 million, with the number of domains sold dropping by almost 14%. The median Sedo sales price kept steady at $2439, up slightly from $2400 last week.

The largest sale this week was Free-SMS.de which went for $164,209, with ConnectionExpress.com taking second place at $30,000. The most undervalued sale was Podium.com which went for only $12,902.

Apple has e-mailed selected media for an invitation-only event on January 27th. The invitation indicates that the event will begin at 10:00 AM and will be held at the Yerba Buena Center for the Arts Theater in San Francisco.

Through leaks, rumors, and wild speculation many expect Apple to announce their tablet, possibly called “iSlate.” The blogging and technology press has been jumping since December 24th when MacRumors announced that Apple owned the “iSlate” trademark and domain name.

UPDATE: Fox News has confirmed that the event will focus on the “tablet device, iPhone 4, and a new round of iLife 2010 software.”

Two six-digit sales pushed Sedo’s weekly numbers up higher than usual, but the median dropped a bit to $2,400. The two big sales were credit.fr for about $850,000 and migraine.com for $125,000. There were sixteen five-digit domains including mysports.com for $60,000, items.com for $50,000, and cityhotels.com for $40,000.

This kind of money pouring into the domain aftermarket is heartening for domain investors to see this early in the year. It should be no surprise to see finance and healthcare taking the top two spots, as those were hot throughout 2009.
