World Cup Drives Prediction Market Trading Volume to New Highs, Bernstein Says Robinhood May Benefit

Bernstein suggests Robinhood is poised for a "strong tailwind" as prediction market trading volumes hit record highs during the World Cup.Data shows that daily trading volume in prediction markets during the early stages of the FIFA World Cup surged from $2.2 billion on June 11 to $4.8 billion on June 12, setting a new all-time high, surpassing the $1.4 billion traded during the previous Super Bowl.Analysts note that prediction markets have become one of Robinhood's fastest-growing revenue lines since their launch. The firm projects Robinhood's prediction market revenue will grow from $150 million in 2025 to $586 million in 2026, representing an increase of approximately 286% year-over-year, and is expected to account for 17% of trading-related revenue and 10% of total revenue in 2026.Bernstein believes Robinhood's partnership with exchange and clearing house Rothera, which is regulated by the U.S. Commodity Futures Trading Commission (CFTC), is a competitive advantage. Since its launch on May 28, Rothera has processed approximately 200 million contracts in 18 days, with FIFA World Cup and MLB-related contracts contributing nearly all of the trading volume. Analysts state that Robinhood's core strength lies in its distribution capability, with its massive user base, a commission of $0.01 per contract, and strategies like up to 50% fee discounts for Gold members helping to drive user engagement.Furthermore, Bernstein indicates that competition in the prediction market space is expanding, including Polymarket launching event contracts for private companies and Kalshi introducing cryptocurrency perpetual contracts. The firm estimates that the World Cup will bring over $3 billion in new betting volume to prediction markets and boost overall consumer trading volume in the industry by $5 billion to $10 billion.

Polymarket's "Post-Hoc Clarification" Sparks Controversy: A Student's $35,000 Prediction Voided, $3.8 Million in Positions Wiped Out

Odaily News The prediction market platform Polymarket issued a "resolution clarification" that overturned a market result that had already appeared to be settled. This led to a 20-year-old student's $35,000 bet being declared invalid, while a total of approximately $3.8 million in positions across 1,838 accounts on the platform were liquidated.This clarification clause was written into the platform's rulebook, allowing for retroactive interpretative corrections to market settlement results, thereby altering the final payout. The incident has sparked strong dissatisfaction among traders, who argue that this "post-hoc ruling" mechanism undermines the certainty of market rules, and has ignited widespread controversy within the Polymarket and Kalshi communities.According to user disclosures, the incident originates from a case made public on June 13, where a market result that had ostensibly been settled was later reversed due to a change in rule interpretation.Industry analysts believe that this type of mechanism introduces "settlement clarification risk" into prediction markets, which is a type of tail risk event that cannot be hedged. If such operations occur frequently, they could drive high-risk liquidity away from the current platform towards trading venues regulated by the CFTC or those with formal arbitration mechanisms.Furthermore, this event is seen as one in a recent series of controversies, including settlement disputes surrounding the UMA oracle and Strategy's Bitcoin-related markets, which continue to test market participants' trust in the "finality" of prediction markets.

Kalshi perpetual contract volume manipulation? Kalshi crypto head's remarks draw questions from Polymarket team members

CNBC recently covered Kalshi Perpetual Contracts, noting that trading volume surpassed $1 billion within the first week of launch.

He also pointed out that it took prediction markets 3.5 years to reach a similar volume scale. Polymarket team member Mustafa Aljadery appeared in the comments section to congratulate, while also inquiring about the Perpetual Contracts' OI (open interest) data, insinuating that Kalshi's trading volume might have been manipulated.Additionally, many community members in the comments expressed doubts about this data, emphasizing that it could be volume generated from zero-fee or leveraged trading. Some even pointed out that Kalshi's OI data stood at only around $4.5 million.

Polymarket: Probability of "Israel will close its airspace before June 30" rises to 64%, a 24H increase of 52%

Odaily Seer Prophecy Channel monitoring shows that on Polymarket, the probability of "Israel will close its airspace before June 30" has risen to 64%, a 24H increase of 52%; additionally, the probability of "Israel will close its airspace before June 15" has risen to 59%, a 24H increase of 52%.Closing airspace refers to the closure of all of Israel's civilian airspace, or a closure covering most of Israel's civilian airspace, resulting in flight cancellations or a complete suspension of commercial aviation, including commercial flights transiting, arriving at, and departing from that airspace. A qualifying closure must apply to flights nationwide in Israel, or to a qualifying major portion of Israel's airspace. Limited-scope flight cancellations, delays, temporary ground stops, or individual regional closures do not meet the conditions for a "Yes" settlement.If there are a few exceptions within the context of a large-scale closure, such as permitting some pre-approved flights to pass, this does not affect the closure being deemed valid. Warnings, no-fly zones, flight suspensions, or other flight restrictions issued by airlines or countries other than Israel cannot serve as sufficient basis for a "Yes" settlement.After the US-Israel-Iran ceasefire on April 8, Iran today launched missiles at Israel again after a two-month interval. Trump stated that his advice to Iran is, since the missiles have been launched, they should now return to the negotiating table and reach an agreement. Trump also said he will call Israeli Prime Minister Netanyahu to tell him not to retaliate.Odaily Seer Prophecy Channel continuously monitors the prediction market, seeing changes before they are priced in.

Polymarket launches "Zcash Orchard Privacy Pool Confirmed Vulnerable Exploit"

Odaily Seer monitoring shows that Polymarket has launched a new prediction event titled "Was Zcash's Orchard privacy pool confirmed to have been exploited?"On June 4, Zcash's core development team revealed that they had deployed an emergency network upgrade to fix a critical cryptographic vulnerability in the Orchard privacy pool. This flaw could have potentially allowed a malicious attacker to arbitrarily forge unlimited amounts of ZEC. Due to the vulnerability's characteristic that "it is impossible to cryptographically prove whether it was exploited in the past," independent support organization Shielded Labs subsequently proposed on June 5 to deploy a new privacy pool during the NU7 upgrade at the end of July. They also suggested implementing strict "Turnstile-accounting" audits for tokens exiting Orchard to investigate whether any forged tokens exist. According to the settlement rules for this prediction event, if before December 31, 2026, official sources or mainstream credible media confirm that the vulnerability was effectively exploited on the mainnet before being patched, the event will settle as YES.Odaily Seer continues to monitor prediction markets, seeing changes before pricing.

Strategy’s Bitcoin Sale Sparks $20 Million Prediction Market Controversy on Polymarket

According to The Block, Strategy disclosed in an SEC filing that it sold 32 BTC between May 26 and May 31, generating approximately $2.5 million in proceeds to pay dividends on its preferred stock. This marks the company’s first Bitcoin sale since December 2022. The disclosure sparked controversy in a Polymarket prediction market—valued at over $20 million in trading volume—that had asked whether Strategy would sell Bitcoin before May 31. The dispute centers on whether the sale qualifies: “Yes” proponents argue the sale occurred before the deadline; “No” proponents contend the information was not publicly disclosed before the market closed and therefore should not count. The market has now entered its final review phase. Polymarket added that “results confirmed outside the deadline will not be recognized,” leaning toward the “No” side. If the dispute escalates further, UMA token holders will vote to resolve it—but prior reports indicate UMA voting power is highly concentrated, with over 60% of active voters linked to Polymarket accounts, raising concerns about impartiality.

Polymarket New Market: "Will the U.S. Congress Pass an Iran War Powers Resolution Before June 30?"

Odaily Seer Prophecy Channel monitoring indicates a new prediction event on Polymarket: "Will the U.S. House and Senate pass the same resolution by June 30, 2026, aimed at limiting U.S. military action against Iran in recent conflicts?"Since the escalation of U.S. military operations against Iran at the end of February this year, the power struggle between the two parties in Congress over the 1973 War Powers Resolution has experienced multiple failures. Although the Senate advanced a related procedural vote in mid-May, and the House also briefly formed a cross-party majority, the House Republican leadership, on the eve of the recess on May 21, cited "absentee members and insufficient votes" to urgently withdraw and postpone the full floor vote. With lawmakers returning to Washington after the Memorial Day recess in early June, the time window for the two chambers to unify the amendment text and complete final passage is extremely compressed. Coupled with the White House's tough stance, potentially using a veto, the market leans toward the view that the two chambers will not reach a substantial binding resolution before the June 30 deadline.Odaily Seer Prophecy Channel continues to monitor prediction markets, seeing changes before pricing.
