New York 'Egg on Face' Showdown: Polymarket Opens Shop, Kalshi Issues Vouchers, What's the Big Idea Behind the Scenes?
Original Article Title: "Polymarket Opens in New York, Kalshi Sprinkles $50 Grocery Vouchers, Is the Prediction Market Also Giving Away Eggs?"
Original Article Author: Wenser, Odaily Planet Daily
"Every generation has its own way of getting eggs," and the value of this statement keeps rising!
This time, the prediction market duopoly sparking this egg battle is Kalshi and Polymarket.
To gain more attention before the "American Spring Festival" Super Bowl, the two major platforms recently began their own "ground promotion performance" in unison—Kalshi distributed $50 worth of free food benefits to users in a certain supermarket in New York; Polymarket went even further, launching a meticulously planned "New York's First Free Grocery Store," scheduled to open on February 12. In terms of vying for attention and user base, the billion-dollar valuation prediction market giant chose the most cliché but effective "offline ground promotion" route.
In response to this, we also contacted our New York-based colleague Connie for the first time, and obtained real information about the "Kalshi, Polymarket offline ground promotion" and "how much can $50 buy in New York, USA," to share with our readers.
When Prediction Market Giants Engage in Ground Promotion: Kalshi Does Flash Mobs, Polymarket Opens a Store with One Click
As the top metropolitan area in the United States, New York has become the battleground and focal point for Kalshi and Polymarket, the two prediction market giants.
And around the escalating cost of living pressure in the New York area and even across the United States, Kalshi and Polymarket have come up with trump cards—

On February 3, Kalshi distributed $50 worth of free food benefits to some users at the West Market on 84 Third Avenue in New York for a limited time to attract more users to participate in various real-world event predictions on the platform.
Based on the surrounding "utility pole mini billboards," "supermarket interior KT boards," and other surrounding materials, Kalshi's offline ground promotion this time seemed more like an impromptu "flash mob event," that is, cooperating with local supermarkets to distribute some offline materials in a short period of time, using the "free $50 food giveaway" benefit as bait to attract people to line up to participate and observe the offline event. This point was also verified and confirmed by Connie.

Additionally, it is evident that through this flash mob event, Kalshi hopes to involve more people in prediction markets with bet-able questions such as "Will this year's New York City oil price exceed $3.3," which are relatable, low-barrier, and easy to understand, to achieve branding and user acquisition goals.


Kalshi Co-Branded Flash Sale Eggs Sold Out
Compared to Kalshi's somewhat rough and highly commercial approach, Polymarket's preparations are undoubtedly more thorough.
On February 3, slightly earlier than Kalshi's official announcement, Polymarket officially announced that after months of careful preparation, they plan to open the "first free grocery store in New York" through an offline store lease on February 12 (EST). Additionally, Polymarket has donated $1 million to the Food Bank For New York City to address the "hunger issue" in the area.

Polymarket also released real shots of offline distribution of vegetables such as tomatoes and eggplants, reminiscent of the bygone era of ground promotion on domestic internet platforms, with a strong sense of "Download the APP to receive eggs" and "First recharge to receive a newcomer's gift package."

It is worth mentioning that Polymarket not only emphasizes that "Polymarket's offline store has sufficient supply, no purchase necessary," but also at the end of the tweet calls on everyone to donate to the Food Bank For New York City, encouraging people to take practical action to address the high food costs and the ongoing high cost of living leading to the "hunger problem."

Seeing this scene, it can't help but make me sigh—
False cryptocurrency project ground promotion: hold offline conferences, indulge in seafood meals, promote various false concept tokens;
Real cryptocurrency project ground promotion: distribute vegetables, give away eggs, open offline stores to provide free food, engage in charity and public welfare, and call on people to donate to show love.

Regarding the real purchasing power of the "Free Egg Event" for Kalshi and Polymarket, we also had a detailed discussion with Connie.
$50 Real Purchasing Power in New York, USA: 5 McDonald's Meals, 1.5 Pounds of Beef, or 2 Days of Meals for an Average Person
According to Connie, $50 in New York, USA, can also be considered "quite valuable."
“Buying 0.5 pounds of beef at a local supermarket in New York, USA costs approximately $18, and $50 can buy about 1.5 pounds of beef,” which is enough protein for an adult for three meals in a day. For comparison, the price of one pound of beef in China is only about 30 RMB, equivalent to 1/8 of the cost in New York, USA.

When converted to the well-known "McDonald's Index," the real purchasing power of $50 is also quite impressive—a takeaway order of a cheeseburger combo with 800-1000 calories costs about $10.89, and $50 can buy 5 combos; if you buy a 580-calorie double cheeseburger, it costs only around $7.2. Of course, this price would be considered "sky high" in China. For the same combo meal, the price in China is only about 25-40 RMB, costing only 1/2 of the same food in New York, USA.


In other words, saving a little money, $50 is close to covering an average person's food cost in New York for about 2 days (calculated based on 5-6 meals). According to Connie, Kalshi's event has attracted many Americans to line up to "receive food," and even "the enthusiasm of Americans lining up to receive things is higher than that of Chinese people." Polymarket's "offline free grocery store" event is also estimated to attract a large number of people to line up and participate. Based on the information released by Kalshi and Polymarket, the upfront costs of the two platforms' related events are at least $50,000 to $100,000.
With such a significant investment of manpower and resources, aside from charity and goodwill, Kalshi and Polymarket, the two major prediction market platforms, also have their own "calculations."
The "Business Acumen" Behind Prediction Market Platforms' "Free Egg Giveaway": Influencing Regulatory Agencies with Political Issues
The above food donation activities by Kalshi and Polymarket were not coordinated or communicated with the New York City government, but were voluntary actions by the companies.
However, the external statements and purposes of both are very similar to the "policies" repeatedly emphasized by New York's newly elected mayor, Zohran Mamdani, during his campaign — the latter had proposed "opening public grocery stores in the five administrative regions of New York to lower food prices." Zohran Mamdani pointed out that city-owned grocery stores could reduce rent and operating costs through a non-profit operating model and the use of public property. This plan is currently in the pilot phase, and the final implementation schedule has not yet been determined.
On the other hand, as one of the key states in the United States, New York legislators are actively issuing new bills regarding the prediction market, an emerging industry track. Among them, the "ORACLE Bill" plans to restrict or prohibit New York residents from betting on certain prediction market events and impose stricter restrictions on event-based prediction markets. Another bill plans to require prediction market operators to obtain a license from the state government before operating.
It is evident that some legislators still have various concerns about the prediction market, viewing it as akin to unregulated gambling or more susceptible to insider manipulation.
In view of this, although the New York City mayor does not have direct regulatory authority over the prediction market (note from the author: regulatory authority over prediction market platforms belongs to state and federal governments), Kalshi and Polymarket's actions may also be an indirect attempt to seek regulatory friendliness.
Lastly, regardless of how the actions of the two regarding "egg donation" ultimately impact, we have to acknowledge that the promotion model of Chinese internet platforms may be at least 5-10 years ahead of the Western world.

Before using Musk's "Western WeChat" X Chat, you need to understand these three questions
The X Chat will be available for download on the App Store this Friday. The media has already covered the feature list, including self-destructing messages, screenshot prevention, 481-person group chats, Grok integration, and registration without a phone number, positioning it as the "Western WeChat." However, there are three questions that have hardly been addressed in any reports.
There is a sentence on X's official help page that is still hanging there: "If malicious insiders or X itself cause encrypted conversations to be exposed through legal processes, both the sender and receiver will be completely unaware."
No. The difference lies in where the keys are stored.
In Signal's end-to-end encryption, the keys never leave your device. X, the court, or any external party does not hold your keys. Signal's servers have nothing to decrypt your messages; even if they were subpoenaed, they could only provide registration timestamps and last connection times, as evidenced by past subpoena records.
X Chat uses the Juicebox protocol. This solution divides the key into three parts, each stored on three servers operated by X. When recovering the key with a PIN code, the system retrieves these three shards from X's servers and recombines them. No matter how complex the PIN code is, X is the actual custodian of the key, not the user.
This is the technical background of the "help page sentence": because the key is on X's servers, X has the ability to respond to legal processes without the user's knowledge. Signal does not have this capability, not because of policy, but because it simply does not have the key.
The following illustration compares the security mechanisms of Signal, WhatsApp, Telegram, and X Chat along six dimensions. X Chat is the only one of the four where the platform holds the key and the only one without Forward Secrecy.
The significance of Forward Secrecy is that even if a key is compromised at a certain point in time, historical messages cannot be decrypted because each message has a unique key. Signal's Double Ratchet protocol automatically updates the key after each message, a mechanism lacking in X Chat.
After analyzing the X Chat architecture in June 2025, Johns Hopkins University cryptology professor Matthew Green commented, "If we judge XChat as an end-to-end encryption scheme, this seems like a pretty game-over type of vulnerability." He later added, "I would not trust this any more than I trust current unencrypted DMs."
From a September 2025 TechCrunch report to being live in April 2026, this architecture saw no changes.
In a February 9, 2026 tweet, Musk pledged to undergo rigorous security tests of X Chat before its launch on X Chat and to open source all the code.
As of the April 17 launch date, no independent third-party audit has been completed, there is no official code repository on GitHub, the App Store's privacy label reveals X Chat collects five or more categories of data including location, contact info, and search history, directly contradicting the marketing claim of "No Ads, No Trackers."
Not continuous monitoring, but a clear access point.
For every message on X Chat, users can long-press and select "Ask Grok." When this button is clicked, the message is delivered to Grok in plaintext, transitioning from encrypted to unencrypted at this stage.
This design is not a vulnerability but a feature. However, X Chat's privacy policy does not state whether this plaintext data will be used for Grok's model training or if Grok will store this conversation content. By actively clicking "Ask Grok," users are voluntarily removing the encryption protection of that message.
There is also a structural issue: How quickly will this button shift from an "optional feature" to a "default habit"? The higher the quality of Grok's replies, the more frequently users will rely on it, leading to an increase in the proportion of messages flowing out of encryption protection. The actual encryption strength of X Chat, in the long run, depends not only on the design of the Juicebox protocol but also on the frequency of user clicks on "Ask Grok."
X Chat's initial release only supports iOS, with the Android version simply stating "coming soon" without a timeline.
In the global smartphone market, Android holds about 73%, while iOS holds about 27% (IDC/Statista, 2025). Of WhatsApp's 3.14 billion monthly active users, 73% are on Android (according to Demand Sage). In India, WhatsApp covers 854 million users, with over 95% Android penetration. In Brazil, there are 148 million users, with 81% on Android, and in Indonesia, there are 112 million users, with 87% on Android.
WhatsApp's dominance in the global communication market is built on Android. Signal, with a monthly active user base of around 85 million, also relies mainly on privacy-conscious users in Android-dominant countries.
X Chat circumvented this battlefield, with two possible interpretations. One is technical debt; X Chat is built with Rust, and achieving cross-platform support is not easy, so prioritizing iOS may be an engineering constraint. The other is a strategic choice; with iOS holding a market share of nearly 55% in the U.S., X's core user base being in the U.S., prioritizing iOS means focusing on their core user base rather than engaging in direct competition with Android-dominated emerging markets and WhatsApp.
These two interpretations are not mutually exclusive, leading to the same result: X Chat's debut saw it willingly forfeit 73% of the global smartphone user base.
This matter has been described by some: X Chat, along with X Money and Grok, forms a trifecta creating a closed-loop data system parallel to the existing infrastructure, similar in concept to the WeChat ecosystem. This assessment is not new, but with X Chat's launch, it's worth revisiting the schematic.
X Chat generates communication metadata, including information on who is talking to whom, for how long, and how frequently. This data flows into X's identity system. Part of the message content goes through the Ask Grok feature and enters Grok's processing chain. Financial transactions are handled by X Money: external public testing was completed in March, opening to the public in April, enabling fiat peer-to-peer transfers via Visa Direct. A senior Fireblocks executive confirmed plans for cryptocurrency payments to go live by the end of the year, holding money transmitter licenses in over 40 U.S. states currently.
Every WeChat feature operates within China's regulatory framework. Musk's system operates within Western regulatory frameworks, but he also serves as the head of the Department of Government Efficiency (DOGE). This is not a WeChat replica; it is a reenactment of the same logic under different political conditions.
The difference is that WeChat has never explicitly claimed to be "end-to-end encrypted" on its main interface, whereas X Chat does. "End-to-end encryption" in user perception means that no one, not even the platform, can see your messages. X Chat's architectural design does not meet this user expectation, but it uses this term.
X Chat consolidates the three data lines of "who this person is, who they are talking to, and where their money comes from and goes to" in one company's hands.
The help page sentence has never been just technical instructions.
