2nd largest company end of May?

Market context

At the end of May, the market is asking which company will sit second in the global market-cap rankings, and the current crowd view prices that outcome at 0% for Yes. That makes the listed favourite effectively any name except the current consensus leader, with Microsoft the obvious benchmark after Polymarket’s end-of-May market showed it as the frontrunner for the top slot. The handicap here is that the second-place finish is usually more stable than the very top spot, because the leader and runner-up often trade places on a narrow valuation spread rather than on a full rerating. In the recent market-cap tables, Alphabet, Apple and Microsoft have all sat in a tight cluster behind NVIDIA, so the live question is less about an outsider breaking in and more about which of the familiar megacaps can hold its relative valuation through month-end.

The main catalysts are the usual month-end drivers: earnings reactions, guidance changes, and any move in rates or megacap multiples that shifts the ranking by a few hundred billion dollars. As of recent coverage, NVIDIA was reported around $5.2 trillion, with Alphabet near $4.2 trillion, Apple at $3.9 trillion and Microsoft at $3.2 trillion, so the spread to second place is wide enough that a sharp move would be needed for a change. That leaves the consensus anchored to the current order unless one of the large constituents gets hit by a company-specific event or a broad tech sell-off. The best contrarian angle is therefore not a dramatic outsider, but the possibility that a fast re-pricing in one of the three largest non-NVIDIA names narrows the gap enough to matter by the settlement cut-off.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
