Weird Things to Gamble On: Craziest Bets Available Online

Aliens

First on my list of weird things you can bet on are aliens! BetUS offers multiple markets for extraterrestrials, including where aliens will be confirmed to exist by the end of 2025 (+250).

Another way to wager on aliens is to bet on whether any well-known celebrities will be revealed as extraterrestrials. BetUS lists the following celebs as favorites to be confirmed as aliens.

• • Dennis Rodman (+1200)
  • Steven Spielberg (+1300)
  • Mark Zuckerberg (+1500)
  • Kanye West (+2000)
  • Miley Cyrus (+2000)

Of course, when you are talking about aliens, you cannot overlook the possibility of an alien abduction. Here are the favorites to be abducted by aliens first.

• • Donald Trump Sr. (+1200)
  • Vladimir Putin (+1800)
  • Elon Musk (+2000)
  • Barrack Obama (+2000)
  • Taylor Swift (+2200)

Both wagers must be graded by the end of 2025. If you feel adventurous and want to try a wager on these, you will find them at BetUS.

Art Auctions

An unusual story from the art world has also created a unique betting opportunity. A lost painting from Spanish surrealist artist Salvador Dalí was discovered in Cambridge in 2023. The painting, titled Vecchio Sultano, was bought during a clearance sale for under $200.

Now that the painting has been confirmed to be a genuine Dalí, it could fetch tens of thousands of dollars at auction.

You and I will not profit directly from the sale of the painting, but we can cash in by betting on the auction. BetOnline has the following odds for the price the painting sells at auction later this year.

• Over $42,000.50 (-120)
• Under $42,500.50 (-120)

The painting will be auctioned on October 23rd in Cambridge. It is valued at between £20,000 to £30,000, or $26,433.17 to $39,649.76 USD.

If you’re interested in this one, it’s available at BetOnline.

Grand Theft Auto 6

Grand Theft Auto 6 has been one of the most highly-anticipated video games of the last decade. Unfortunately, the pressure to live up to expectations and other development issues have caused the game to be delayed several times. Recent reports suggest that GTA 6 could be delayed again.

The long wait for GTA 6 has been much maligned by the internet and created several memes. Bettors can also bet on GTA 6 in various ways.

NEW GTA 6 LEAKED INFO:

The game is planned for release in May 2026, but internal discussions hint at a possible delay to September 2026.

It will be available in three editions: Standard ($69.99), Deluxe ($89.99) which includes early access to GTA Online, and Premium… pic.twitter.com/vBaSguNFyf

Bovada offers this prop on the release date of GTA 6:

• GTA 6 released first (-3500)
• Aliens confirmed to exist first (+900)

For reference, Bovada lists the odds of a living extraterrestrial to be found on Earth in 2025 at +6000 odds. While the GTA 6 release is a heavy favorite to come first, it is not guaranteed. At 9-1 odds, the confirmation of alien life has an implied win probability of 10%.

Another option for betting on GTA 6 is this wager from BetUS: Will a new GTA 6 Trailer be released in 2025?

• Yes (-125)
• No (-115)

The game’s current release date is May 26th, 2026. Rockstar has released two trailers so far for the long-awaited game. A new trailer could give fans something to talk about and distract them from yet another delay.

TikTok Sale

TikTok is one of the most popular social media apps in the US. However, the future of the app has been in jeopardy for over a year.

After a brief ban in January 2025, the app returned service to US users. Unfortunately for fans of the app, the future of TikTok is once again in doubt. BetUS lists TikTok at +200 odds to be sold before the end of 2025.

The latest extension by President Trump gave ByteDance, TikTok’s parent company, until September 17th to sell the app to a US-based company. Rather than sell the app, some reports suggest that ByteDance is creating a new, TikTok-like app that will only be available to users in the US.

Creating a new app could temporarily solve ByteDance’s problems. However, if the new app is still owned by a Chinese-based company, it will continue to draw the ire of anti-TikTok politicians.

The Enhanced Games

The Enhanced Games seek to find the true limits of human performance by allowing athletes to use doctor-approved performance-enhancing drugs (PEDs). Organizers have had to overcome several hurdles, but, barring another setback, the first-ever Enhanced Games will finally take place in 2026.

BetUS offers multiple markets for the inaugural Enhanced Games, such as:

• • Which athletes will compete?
  • How many world records will be broken?
  • What events will take place?

The current events for the 2026 Enhanced Games include four swimming events, three track and field races, and two weightlifting competitions. However, there is plenty of time between now and next spring to add more events and participants to this one-of-a-kind sporting venture.

Next Owner of OnlyFans

The announcement that the controversial social media platform OnlyFans could be sold soon has generated a lot of buzz about the potential new owners. Thanks to Bovada, you can wager on the next owner of the platform.

OnlyFans was valued at $8 billion, so only a few investor groups have the capital to buy the site. Bovada lists the following groups as the favorites to purchase the platform.

• • Forest Road Company (-125)
  • Any other group including Conor McGregor (+650)
  • Apollo Global Management (+950)
  • Binance (+1000)
  • KKR & Co (+1200)
  • Public Offering (IPO) (+1200)

Longshots for this wager include Meta (+1800), Mark Cuban (+2800), and Elon Musk (+3500).

Forest Road Company is the favorite, and it is easy to see why. The investment group has spent years aggressively acquiring entertainment, media, real estate, and other businesses.

For this wager to have action, the sale must be completed by the end of 2025.

San Jose Treasure

More than three centuries after the San Jose crashed off the coast of Colombia, the “holy grail” of shipwrecks is offering bettors a chance to win their own small fortune. The wreck itself is rumored to hold billions of dollars’ worth of treasure.

Before you go spending money on diving gear, the treasure is already being excavated by the Colombian government. However, governments from other countries, including Spain and Peru, have laid claim to the underwater treasure trove.

More than 300 years after the Spanish galleon San José sank off the coast of Colombia in 1708, a cluster of glittering gold coins from what’s often called the “world’s richest shipwreck” is helping archaeologists confirm the vessel’s final resting place. https://t.co/CSLBd4ogpH

Luckily, BetOnline offers a unique market for the treasure, so bettors can cash in on the discovery without having to get their feet wet.

BetOnline has the following odds on which country or group will be declared as the owners of the treasure from the San Jose shipwreck.

• • Colombian Government (+150)
  • Spanish Government (+250)
  • Sea Search Armada (+350)
  • Peruvian Government (+400)
  • Indigenous Population (+1200)
  • Any other (+750)

The wreck is located on the Colombian coast, and the government of Colombia has been excavating the site. So, it comes as no surprise that the Colombian government is a +150 favorite. However, the ship was originally a Spanish vessel, and Spain is a close second at +250.

Extinct Animals

Speaking of betting on unique discoveries at BetOnline, this sportsbook also has odds on the next extinct animal to be revived.

Advances in cloning and genetic engineering have allowed scientists to bring back previously extinct species. A recent example of de-extinction is the dire wolf, which went extinct 10,000 years ago. Scientists at Colossal Biosciences created three wolf pups genetically modified with DNA from the dire wolf.

BetOnline offers the following odds for the next animal to be revived from extinction.

• • Passenger pigeon (+200)
  • Woolly mammoth (+250)
  • Tasmanian Tiger (+300)
  • Giant Ground Sloth (+300)
  • Moa (+400)
  • Megalodon (+600)

Other options in this betting market include the Saber-toothed tiger (+800), the dodo bird (+1000), and the golden toad (+2500).

Many of the top betting options, including the passenger pigeon and woolly mammoth, are already decades into de-extinction efforts but are expected to return soon.

A passenger pigeon hybrid, for instance, is expected to begin captive breeding by 2032.
